4.68
5.84
7.85
5.12
Answer:
5.84
Step-by-step explanation:
She has two shirts and their 23.99 each
23.99 x 2 = 47.98
Then she has a pair shoes that cost 41.99
Add
47.98 + 41.99 = 89.97
6.5% = 0.065
89.97 x 0.065 = 5.84
A short quiz was to be held at Meenakshi's school. As an unprepared student, she planned to randomly guess all the answers on the twelve true or false questions. What is the probability that at least 2 of Meenakshi's answers will be correct?
Answer:
0.9968
Step-by-step explanation:
Given that:
P of being correct = 0.5 (since there are only 2 options in each question with only one bring correct).
1 - p = 1 - 0.5 = 0.5
Number of questions, n = 12
Probability that atleast 2 questions are correct
P(x ≥ 2) = p(x = 2) + p(x = 3) +... + p(x = 12)
P(x =x) = nCx * p^x * (1 - p)^(n - x)
The sun of the individual probabilities gives us the answer or we could use the binomial probability calculator :
Hence,
P(x ≥ 2) = 0.9968

What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number of days to repair 8 km be represented as A
Now , the proportion will be
Let the distance be = 1250 meters = 1.250 km
The number of days to repair 1.250 km is = 5 days
Substituting the values in the equation , we get
5 / 1.250 = A / 8
Multiply by 8 on both sides of the equation , we get
A = ( 8 x 5 ) / 1.25
A = 40 / 1.25
A = 32 days
Hence , the number of days is 32 days

Find the distance along an ark on the surface of the earth that subtends a central angle of 10 minutes (1 minutes 1/60 degree) The radius of the earth is 3960 miles around to the thousands
Answer:
11.52 miles
Step-by-step explanation:
We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.
Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles
So L = Ф/360 × 2πR
= (1/6)°/360 × 2π(3960 miles)
= 1/2160 × 7920π
= 3.67π
= 11.52 miles
What is 524 rounded to nearest 10
Answer:
520
Step-by-step explanation:
When rounding to the nearest ten, like I did with 524 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
What is the image point of (7,-7) after a translation of 3 right and 1 down followed by
a reflection over the x-axis?
Answer:
The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:
P''(10, 8)Step-by-step explanation:
Given the point
(7, -7)
Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate
Therefore, the translation rule:
(x, y) → (x+3, y-1)
In our case, let the point P(7, -7)
P(7, -7) → P'(7+3, -7-1) → P'(10, -8)
FOLLOWED BY A reflection over the x-axis
We know that the rule of reflection over the x-axis implies that
(x y) → (x, -y)
i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.
After the first transformation, we had got P'(10, -8)
so
P'(10, -8) → P''(10, -(-8)) → P''(10, 8)
Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:
P''(10, 8)Solve for p.

You have twenty blankets that each take up 704 cubic inches of space. How many blankets could you pack into a 22-inch moving box?
Answer:
32
Step-by-step explanation:
i don't know if its right but i did 704 divided by 22 which equals to 22
We can pack a maximum of 15 blankets into the 22-inch moving box.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine how many blankets can fit in a 22-inch moving box, we first need to calculate the volume of the box.
Since the box is 22 inches in all three dimensions (length, width, and height), its volume is:
= 22 x 22 x 22
= 10,648 cubic inches
Next, we need to divide the volume of the box by the volume of one blanket to find out how many blankets can fit inside.
= 10,648 / 704
= 15.125
We can't fit a fraction of a blanket, so we can only pack a whole number of blankets.
Therefore,
We can pack a maximum of 15 blankets into the 22-inch moving box.

Answer: 28 shirts
Step-by-step explanation:
From the question, we are informed that Lisa sold 11 shirts for every 7 shirts Becky sold. This can be expressed in a fraction as:
Lisa = 11/(11 + 7) = 11/18
Becky = 7/(11 + 7) = 7/18

If 38% of a number, n, is 24.32, what is 20% of n?
Answer:
20 % of n would be 12.8
Step-by-step explanation:
By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.
The 20% of n is 12.8
38% of number n is given as:
[tex]38\% \times n = 24.32[/tex]
Express the percentage (38%) as decimal
[tex]0.38 \times n = 24.32[/tex]
Divide both sides of the equation by 0.38
[tex]n = 64[/tex]
Multiply both sides of the equation by 20%
[tex]20\% \times n = 20\% \times 64[/tex]
Express the percentage (20%) as decimal
[tex]20\% \times n = 0.20 \times 64[/tex]
Evaluate the product
[tex]20\% \times n = 12.8[/tex]
Hence, the 20% of n is 12.8
