Answer:
0.28 meters per second.
Step-by-step explanation:
We have that the speed formula is as follows:
v = d / t
In this case they tell us that the distance is 2 km the equivalent of 2000 meters and the time is 2 hours the equivalent of 7200 seconds, we replace and we are left with:
v = 2000/7200 = 0.28
Therefore it ran 0.28 meters per second.

A swim team must be chosen from 10 candidates. What is the greatest number of different four-person teams that can be chosen?
Answer:
There are a total of 210 different four-person teams that could be chosen.
Step-by-step explanation:
In order to calculate the greatest number of different four-person teams we need to calculate the combination of 10 people taken four by four as shown below:
[tex]C_{10,4} = \frac{10!}{4!(10 - 4)!}\\C_{10,4} = \frac{10!}{4!*6!}\\C_{10,4} = \frac{10*9*8*7*6!}{4!*6!}\\C_{10,4} = \frac{10*9*8*7}{4*3*2}\\C_{10,4} = \frac{5040}{24} = 210[/tex]
There are a total of 210 different four-person teams that could be chosen.
solve for b. b - 7/4 = -2/3
Answer:
1 1/12
Step-by-step explanation:
b - 7/4 = -2/3
Add 7/4 to each side
b - 7/4+7/4 = -2/3+7/4
b = -2/3+7/4
Get a common denominator
b = -2/3 *4/4 + 7/4 *3/3
= -8/12 + 21/12
=13/12
= 12/12 +1/12
= 1 1/12

The sum of all digits in the numbers 44, 45 and 46 is 27 because (4+4)+(4+5)+(4+6)=27. Find the sum of digits in the first 25 counting numbers: 1, 2, 3, …, 25. NEED HELP PLEASE!!!!!!!!!!!!!!!!!!!!
Answer:
Total um of the digits of the first 25 numbers is 127
Step-by-step explanation:
Notice that:
The sum of the digits:
0+1+2+3+4+5+6+7+8+9 = 45
Also notice that the addition of:
10+11+12+13+14+15+16+17+18+19=0+1+2+3+4+5+6+7+8+9 + 10*1 = 45 + 10 = 55
And for the last 6 numbers:
20+21+22+23+24+25 = 0+1+2+3+4+5 + 2 * 6 = 15 + 12 = 27
So the total sum of all this is: 45 + 55 +27 = 127

Steve works at an apple orchard and is paid by the bushel for the apples he harvests each day. If Steve harvests 42 bushels or less per day, he is paid y dollars per bushel. If Steve harvests more than 42 bushels per day, he receives y dollars per bushel for the first 42 bushels and is paid 1.5 times that amount for each additional bushel. How many bushels of apples did Steve harvest yesterday
Answer:
The information given in the question to solve it is insufficient.
The complete question related to this found at GMAT club forum is stated below:
Steve works at an apple orchard and is paid by the bushel for the apples he harvests each day. For the first 42 bushels Steve harvests each day, he is paid y dollars per bushel. For each additional bushel over 42, he is paid 1.5y. How many bushels of apples did Steve harvest yesterday?
1. Yesterday, Steve was paid $180 for the apples he harvested.
2. Today, Steve was paid $240, and he harvested 10 more bushels of apples than he harvested yesterday.
Step-by-step explanation:
1st 42 bushels Steve harvests each day:
Payment of 1 bushel = y dollar
Payment of ≤ 42 bushel = 42× y = $42y
Payment for Additional bushel after the 1st 42 bushels = 1.5y per bushel
Yesterday's Payment = $180
Today's payment = $240
Let the total number Steve harvested yesterday = p
Today he harvested 10 more bushels than he did yesterday
Total number Steve harvested today = p + 10
Now looking at the information in the question:
First statement did not tell us the amount he harvested that got him that pay, so it's insufficient. Second statement alone two is not sufficient to determine yesterdays pay.
In both statement, we were not told if he harvested more or less than 42 yesterday. Neither were we told if the additional 10 bushels was after he had harvested more than 42 bushels.
Let's assume the additional 10 bushels was after he had harvested more than 42 bushels (that is he harvested 42 yesterday) .
Difference in payment = 240-180 = 60
For the additional 10bushels, he was paid $60
10(1.5y) = 60
15y = 60
y = 60/15 = 4
If y = $4 per bushel and he was paid $180, the number he harvested will be:
4 × number of bushels = $180
4p = 180
p = 180/4 = 45 bushels
p = 45bushels isn't possible because the amount for the first bushels should either be less than or equal to 42
If we make another assumption, let's say he harvested more than 42 yesterday (42 + an additional number), we would get a different answer.
Thus the information given in the question to solve it is insufficient.

Jon recently drove to visit his parents who live 528 miles away. On his way there his average speed was 14 miles per hour faster than on his way home (he ran into some bad weather). If Jon spent a total of 22 hours driving, find the two rates.
Answer:
speed while going = 42, while returning home = 28
Step-by-step explanation:
let his speed on the way to his parents house is (x)
then his speed while returning is x - 14
Time = Distance / speed
528 / x + 528 / x -14 = 22
multiplying the denominator ...
528x + 528x +7392 = 22x^2 +14x
1056x + 7392 = 22x^2 + 308x
0 = 22x^2 -748x -7392
"dividing by 22"
0 = x^2 -34x-336
0 = (x+8) (x-42)
x must be 42
finally jon's speed while back home is 42 - 14 = 28
What is the nth term rule of the quadratic sequence below? 7, 14, 23, 34, 47, 62, 79 Please could someone help me and write a step by step explanation? Thanks :D
Step-by-step explanation:
The first differences are 7,9,11,13,15,17 and the second differences are 2.
This means that the first term of the sequence is n^2.
Subtracting n^2 from the sequence gives 6,10,14,18,22,26, which has nth term of 4n + 2.
So putting these together gives a nth term of the quadratic sequence of n^2 + 4n + 2.
Hope it helped and tell me if I went wrong :)
When Gene and Kelly were planning their trip to Paris, one United States dollar was worth about $\frac{7}{10}$ of a euro. Before they left, they took 1,000 dollars to the bank and converted them into euros. Two weeks later, they returned home to the United States with 196 euros. To the nearest dollar, how many dollars did they bring back?
Answer:
$280 dollars
Step-by-step explanation:
When they were leaving
[tex]\$1 \approx \frac{7}{10}$ Euro\\Therefore:\\\$1000 \approx \dfrac{7}{10}\times 1000 =700$ Euro[/tex]
When they returned home, they brought 196 Euros.
[tex]If\:\:\$1 \approx \frac{7}{10}$ Euro\\Then: 1 Euro $=\$ \dfrac{10}{7}\\\\$Therefore:\\\\196 Euros = \$ 196 \times \dfrac{10}{7} =\$280[/tex]
They brought back $280 dollars to the United States.
Answer:
They brought back 280 dollars.
Step-by-step explanation:
From the question, one United States dollar was worth about $\frac{7}{10}$ of a euro implies that:
$1 = 7/10 euro, or 0.70 euro. That is, the exchange rate is $1:0.70 euro.
The equivalence of the exchange $1:0.70 euro can also be obtained by dividing both sides by 0.70 as follows:
$1 / 0.7 = 0.7 / 0.7 => $1.43:1 euro. That is, $1.43 is equal to one euro.
Since they returned with 196 euros and $1.43 is equal to one euro, we will simply multiply 196 euros by $1.43 to obtain the amount of dollars they brought back as follows:
Amount of dollars they brought back = $1.43 * 196 = $280 to the nearest dollar.
Therefore, they brought back 280 dollars.

After the first 4 quizzes, Ron’s quiz average is an 87. There are two quizzes remaining for the quarter and the maximum score for any individual quiz is 100. What is the minimum grade Ron can score on one of these two quizzes and still score high enough on the other so that the final quiz average of the six quizzes is at least a 90?
Answer:
Minimum = 92 ; maximum =100
Step-by-step explanation:
Total number of quizzes = 6
Number of completed quizzes = 4
Number of quizzes left = 2
Average score on completed quizzes = 87
Target average = 90
Maximum score for any individual quiz = 100
Current total score on the 4 quizzes to obtain an average of 87:
87 * 4 = 348
To obtain an average of 90:
Total score must in the six quizzes must be :
90 * 6 = 540
Therefore total score needed in the remaining 2 quizzes to attain an average of 90:
540 - 348 = 192
Since the highest attainable score is 100:
Maximum score Ron can attain on one quiz = 100
Minimum he can attain in the other = 192 - 100 92 in other to score an average of 90 in the six quizzes.

3 and 3y4x and 4yAccording to the Insurance Institute of America, a family of four spends between $400 and $3,800 per year on all types of insurance. Suppose the money spent is uniformly distributed between these amounts. If we select a family at random, what is the probability they spend less than $2,000 per year on insurance per year? (Round your answer to 4 decimal places.)
Answer:
0.471
Step-by-step explanation:
Calculation for the probability that they spend less than $2,000 per year on insurance per year
First step is to find the base
Base =$2,000-$400
=$1,600
Second step is to find the probability using this formula
P=1/b+a×base
Where,
b represents $3,800
a represents $400
base represents $1,600
Let plug in the formula
P=1/$3,800-$400×$1,600
Hence,
P=1×$1,600/$3,800-$400
P=$1,600/$3,400
P=0.471
Therefore the probability that they spend less than $2,000 per year on insurance per year will be 0.471
Which measurements could represent the side lengths of a right triangle?
4 m, 6 m, 10 m
5 ft, 8 ft, 9 ft
O 16 cm, 30 cm, 34 cm
o 18 in., 24 in., 42 in.
Answer:
16 cm, 30 cm, 34 cm
Step-by-step explanation:
I got this answer simply by plugging each number into my calculator with the following equation:
[tex]\sqrt{x^{2} +y^{2} }[/tex]
When you the lower numbers into the equation, if the lengths really do give you a triangle, then you should get the largest number as your output. This can help you with any of the other questions that you may have to answer.
Only the measurements of 16 cm, 30 cm, and 34 cm could represent the side lengths of a right triangle.
What are Pythagorean triplets?In a right-angled triangle, its sides, such as hypotenuse, and perpendicular, and the base is Pythagorean triplets.
Here,
The side lengths of a right triangle must satisfy the Pythagorean theorem, which states that the sum of the squares of the two shorter sides (the legs) is equal to the square of the longest side (the hypotenuse). Therefore, we need to check which sets of measurements satisfy this condition.
Only the measurements of 16 cm, 30 cm, and 34 cm could represent the side lengths of a right triangle.
For the first set of measurements, we have:
a = 16 cm, b = 30 cm, c = 34 cm
a² + b² = 256 + 900 = 1156
c² = 1156
Since a² + b² = c², these measurements do represent the side lengths of a right triangle.

What is the measure of ZE, in degrees?
Answer:
B. 84 deg
Step-by-step explanation:
Sides DE and FE are congruent since they both have the same length.
That makes angles D and F congruent.
m<D = m<F = 48
The sum of the measures of the angles of a triangle equals 180 deg.
m<E + m<D + m<F = 180
m<E + 48 + 48 = 180
m<E = 84
