She logs 18,000 feet of walking each shift based on perimeter of the rectangle field.
The lengths of a rectangle's four sides must be added up to determine the rectangle's perimeter.
The perimeter (P) of a rectangle of length L and width W can be calculated using the following formula:
P = 2L + 2W
For instance, the perimeter of a rectangle with dimensions of 10 metres in length and 5 metres in width would be:
[tex]P = 2(10) plus 2(5) equals 20 plus 10 metres.[/tex]
Hence, the rectangle's perimeter is 30 metres.
The fencing has a length and a width and is rectangular in design.
Size: 5000 feet
width is 4000 feet.
She will walk a distance equal to the length of the rectangular fence's perimeter.
Perimeter = 2 (length + width) = 2 (5000 + 4,000) = 2 (9000) = 18,000 ft.

which number of hours and minuets is closest to the amount of time that the jet has been flying if the jet is 1,500 miles from los angeles
Answer: 11550
Step-by-step explanation:
First you add 475+2650=11550
The model shows that 3 and one fifth divided by four fifths equal 4 what would happen if you divide by 8/5 instead of 4/5
Dividing by a larger fraction (8/5) instead of 4/5 results in a smaller answer (2), because we are dividing the same amount (16/5) into more parts (8) compared to dividing by 4/5.
If you divide 3 and one fifth by four fifths, you can first convert the mixed number to an improper fraction:
3 and 1/5 = (3 x 5 + 1) / 5 = 16/5
Then, you can perform the division as follows:
(16/5) / (4/5) = (16/5) x (5/4) = 4
So, we get an answer of 4.
If we divide by 8/5 instead of 4/5, we can use the same process but with the new fraction:
(16/5) / (8/5) = (16/5) x (5/8) = 2
So, the answer would be 2.
This is because when we divide by a smaller fraction, we are dividing the same amount into fewer parts, which results in a larger answer.

True, True, True
What is the speed of an object?The speed of an object is the ratio of the distance traveled by the object to the duration of the motion.
The distance sprinters are to run = 150 meters
The speed of sprinter A = 6 m/s
Speed of sprinter B = 5 m/s
The head start of sprinter B = 10 meters
Statement A; Sprinter A is leading the race at the 12 seconds mark
At the 12 seconds mark, we get;
The distance covered by sprinter A = 6 m/s × 12 s = 72 m
The distance covered by sprinter B = 10 m + 5 m/s × 12 s = 70 m
Therefore, sprinter A is leading sprinter B at the 12 seconds mark
Statement A is True

The sum of

55 consecutive odd numbers is
135
135135. What is the second number in this sequence?
The second term of the finding sequence is 25.
When you are confronted by a question like this, you can make a simple equation, combine like terms, isolate the variable, and solve.
"5 consecutive odd numbers" basically means x + (x + 2) + (x + 4) + (x + 6) + (x + 8). Each time you add 2 more to ensure there are no even numbers. Otherwise, it wouldn't be only consecutive odd numbers.
We are told the sum of these numbers is 135. This means x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135.
(x + 0) + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
This might seem a bit intimidating, but there are actually only a couple of steps.
Combine like terms.
In this case, the like terms are the 5 times x appears and the numbers 0, 2, 4, 6, and 8.
x + x + x + x + x = 5 • x, or 5x.
0 + 2 + 4 + 6 + 8 = 20
So by combining like terms, we can simplify (x + 0) + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135 down to just 5x + 20 = 135.
Isolate the variable.
Now we just have to isolate x. The value of x is the lowest term in the sequence.
5x + 20 = 135
To isolate x, first subtract 20 from both sides. Then, divide both sides by 5.
5x + 20 - 20 = 5x
135 - 20 = 115
5x = 115
5x / 5 = x
115 / 5 = 23
x = 23
The lowest term in the sequence is 23.
Identify all numbers in the sequence.
Now that we know x, we can find the rest of the numbers in the sequence by plugging the lowest value into the original equation we created.
(x + 0) + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
(23 + 0) + (23 + 2) + (23 + 4) + (23 + 6) + (23 + 8) = 135
23 + 0 = 23 This is the first and lowest term in the sequence.
23 + 2 = 25 This is the second term in the sequence.
23 + 4 = 27 This is the third term in the sequence.
23 + 6 = 29 This is the fourth term in the sequence.
23 + 8 = 31 This is the fifth and last term in the sequence.
Now we know the sequence is 23, 25, 27, 29, 31.
Finding the Answer:
To find the answer, locate the second term in this sequence.
23, 25, 27, 29, 31
The second term is 25.

Ye chord is drawn from a pack of 52 cards find the probability of getting a queen or a diamond or a black card
Answer:
There are 4 queens in a pack of 52 cards, and there are also 13 diamonds and 26 black cards (13 clubs and 13 spades).
To find the probability of getting a queen or a diamond or a black card, we need to add the probabilities of each event happening and subtract the probability of getting a card that is both a queen and a diamond (the queen of diamonds).
Probability of getting a queen = 4/52 = 1/13
Probability of getting a diamond = 13/52 = 1/4
Probability of getting a black card = 26/52 = 1/2
Probability of getting the queen of diamonds = 1/52
So, the probability of getting a queen or a diamond or a black card is:
(1/13) + (1/4) + (1/2) - (1/52) = 51/52 or approximately 0.98
Therefore, the probability of getting a queen or a diamond or a black card is approximately 0.98.

Two similar polygons have areas of 128 in2 and 98 in2. If the smaller polygon has a perimeter of 42 in, what is the perimeter of the larger polygon?
In response to the query, we can state that Hence, the bigger polygon's equation circumference measures around 54.86 inches.
What is equation?In a math equation, two assertions are connected by the equals sign (=), which denotes equivalence. A mathematical assertion used in algebraic equations establishes the equivalence of two mathematical statements. For instance, in the equation 3x + 5 = 14, the equal sign creates a space between the values 3x + 5 and 14. To comprehend the relationship between the two sentences written on opposing sides of a letter, utilise a mathematical formula. The logo and the specific programme typically correspond. An illustration would be 2x - 4 = 2.
Area of a smaller polygon is equal to (k * side of a smaller polygon)2.
bigger polygon's area is equal to (k * side of larger polygon)2.
Area of bigger polygon / area of smaller polygon = (k * side of larger polygon) / (k * side of smaller polygon) /
[tex]\sqrt(128/98) k * 42 = (48 / side of smaller polygon) * 42 = 48 * (42 / side of smaller polygon) = (k * side of bigger polygon) / (k * 42)[/tex]
Greater polygon's perimeter is equal to 48 * (42 / smaller polygon's side) [tex]= 48 * (42 / (42k)) = 48 * (1/k).[/tex]
We may utilize the fact that the ratio of the two polygons' surface areas is to calculate k:
bigger polygon's area divided by smaller polygon's area equals 128/98, or 64/49.
the ratio of the sides of the two polygons is 8/7.
K thus equals 7/8.
Hence, the bigger polygon's circumference measures around 54.86 inches.

At a scout jamboree, dinner is served from tinned food. Each tin of soup is shared between 2 scouts. each tin of frankfurters is shared between 3 scouts and each tin of fruit is shared between 4 scouts. If 117 tins are opened to feed all the scouts, how many scouts attended the jamboree
Answer:
108
Step-by-step explanation:
Let's assume that there are "x" scouts attending the jamboree.
The number of tins of soup required to feed x scouts would be x/2.
The number of tins of frankfurters required to feed x scouts would be x/3.
The number of tins of fruit required to feed x scouts would be x/4.
Therefore, the total number of tins required to feed x scouts would be:
x/2 + x/3 + x/4 = (6x + 4x + 3x) / 12 = 13x/12
Since we know that 117 tins were opened, we can set up the equation:
13x/12 = 117
Solving for x, we get:
x = 108
Therefore, there were 108 scouts attending the jamboree.

a. The probability of a correct decision on each trial is 0.1.
b. The expected number of correct decisions in seven trials is 0.7.
c. The probability of no correct decisions in seven trials is approximately 0.478.
d. The probability that the psychic guesses incorrectly in all seven trials is approximately 0.0078.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
a. If the psychic is guessing (i.e., does not possess ESP), there are 10 boxes, and only one of them contains the crystal.
Therefore, the probability of a correct decision on each trial is -
p = 1/10 = 0.1
b. If the psychic is guessing, the expected number of correct decisions in seven trials can be found by multiplying the probability of a correct decision on each trial (0.1) by the number of trials (7) -
E(X) = np = 7 × 0.1 = 0.7
Therefore, the number of correct decisions is 0.7.
c. If the psychic is guessing, the probability of no correct decisions in seven trials can be found using the binomial distribution formula -
[tex]P(X=0) = (n\ choose\ x) \times p^x \times (1-p)^{(n-x)}[/tex]
In this case, n = 7, x = 0, and p = 0.1.
Substituting these values into the formula, we get -
[tex]P(X=0) = (7\ choose\ 0) \times 0.1^0 \times 0.9^7 = 0.478[/tex]
Therefore, the probability value is 0.478.
d. If the psychic has ESP and p = 0.5, the probability of guessing incorrectly on any trial is -
q = 1 - p
q = 1 - 0.5
q = 0.5
The probability of guessing incorrectly in all seven trials can be found using the binomial distribution formula -
[tex]P(X=7) = (n\ choose\ x) \times p^x \times q^{(n-x)}[/tex]
In this case, n = 7, x = 7, p = 0.5, and q = 0.5.
Substituting these values into the equation, we get -
[tex]P(X=7) = (7\ choose\ 7) \times 0.5^7 \times 0.5^0 = 0.0078[/tex]
Therefore, the probability value is 0.0078.

a) What is the expected number of times the die comes up 6, when it is rolled 32 times?b) What is the expected number of times the die must be rolled until the first 6 comes up?Solutions:Part a) Let X be the number of times the die comes up 6 when it is rolled 32 times.To find the expected number of times the die comes up 6, we'll apply the formula E(X) = np, where n is the number of trials and p is the probability of success on any given trial.If we look at the bias in this particular cubic die, we see that when the event is {6}, then p({6}) = p = 2p/4. This implies that p = 2/7, therefore: E(X) = np = 32*2/7 = 9.14285714286 = 9.14Part b) Let Y be the number of times the die must be rolled until the first 6 comes up.Let's use the geometric distribution to calculate the expected number of rolls E(Y).Since the event "6" has a probability of 1/7, then p = 1/7. Thus, the expected number of times the die must be rolled until the first 6 comes up is given by E(Y) = 1/p, which is 7 rolls.Hence, the answers are a) 9.14 and b) 7.

The diagonals of parallelogram ABCD intersect at E. If AE=2x+ 4., EB=6+3y,EC=15-y and ED =x+4 then, find the lengths of diagonals AC and BD.
The length of the diagonals AC and BD are 28 and 18 units respectively.
How to find the diagonal of a parallelogram?A parallelogram is a quadrilateral that has opposite sides equal to each other and opposite sides parallel to each other. The diagonal of a parallelogram are not equal but they bisect each other.
Therefore,
AE = EC
EB = ED
Hence,
2x + 4 = 15 - y
2x + y = 11
6 + 3y = x + 4
x - 3y = 2
Combine the equation
2x + y = 11
x - 3y = 2
multiply equation(ii) by 2
2x + y = 11
2x - 6y = 4
7y = 7
y = 7 / 7
y = 1
Let's find x
x = 2 + 3y
x = 2 + 3(1)
x = 2 + 3
x = 5
Therefore,
x = 5 and y = 1
AE = EC = 2(5) + 4 = 14
AC = 14(2) = 28 units
EB = ED = 6 + 3(1) = 9
BD = 9(2) = 18 units

A net for a cube has a total surface area of 150 in.2. what is the length of one side of a square face?
a. 4 in.
b. 5 in.
c. 16 in.
d. 25 in.
The length of one side of a square face is 5 inches
The surface area of a cube is given by 6s^2, where s is the length of one side of a square face. If the net for a cube has a total surface area of 150 in^2, we can set up an equation:
6s^2 = 150
Dividing both sides by 6, we get:
s^2 = 25
Taking the square root of both sides, we get:
s = 5
Therefore, the length of one side of a square face is 5 inches.
So, the answer is (b) 5 in.

help please and thankyou it’s due soon
Answer:
w=20cm
Step-by-step explanation:
Tough question.
We are not told whether the surface area is only what can be seem from the top, or does it include regions beneath the butterfly. I made the assumption it is from the top
I had to make an assumption that since the butterfies are similar, they wll have the same ratio of width and height. We will assume an "effective height," a value of height that when multiplied by the width will yield the correct surface area of 53 cm^2.
See the attached worksheet.
The effective height for the smaller butterfly is 13.25cm. This multiplied by the given width (4cm) produces the surface area of 53 cm^3. The ratio of width to height (w/h) is 0.302.
We've already made the assumption that the width to height of the larger butterfly will be the same. Now we can use the larger area (1325 cm^2) with the width to height ratio as follows:
Area = w*h
Since w/h is = 0.302, we can write w = 0.302h or h = (w/0.302)
1325 cm^2 = w*h
1325 cm^2 = w*(w/0.302)
w^2 = 200
w = 20 cm
(I made several assumptions in this analysis. Review them carefully).
What is the perimeter of triangle jeg? 60 units 65 units 70 units 75 units
The perimeter of the triangle jeg is 60 units where the sides of the triangle are given.
What is perimeter?Perimeter is the total distance around the outer boundary of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.
According to question:EK = x + 5
KJ = x +5
FG = 2x
GH = 3x - 5
Assuming that the triangle is equilateral:
equate GH = FG
3x - 5 = 2x
solve for x
x = 5
therefore, one side of the triangle is
(x + 5) + (x + 5) = 20
and the equilateral triangle's perimeter is
3×one side = 3 ×20 units
Thus, Perimeter = 60 units.

Increase 402€ by 23%
The value of 402€ after increasing by 23% is 494.46€. The solution has been obtained by using the arithmetic operations.
What are arithmetic operations?
The four basic operations, often known as "arithmetic operations," are said to be able to adequately explain all the real numbers. The mathematical operations following division, multiplication, addition, and subtraction are quotient, product, sum, and difference.
We are given a value as 402€ which is to be increased by 23%.
So, by using the addition operation, we get the value as,
⇒ 402€ + 23%
⇒ 402€ + 92.46€
⇒ 494.46€
Hence, the value of 402€ after increasing by 23% is 494.46€.
