If the area of a square is 36 inches what is the length of one side?

To find the length of a square given the area, we just need to take the square root of the area given. The sqrt of 36 is 6, so each side is 6 inches. :)

Well, a square has four sides. So if you divide four into 36, you get 9. So the answer is 9. But the reason that the answer is nine, is because

So a square has four sides, and every side of that square added together equals 36. And if theres four sides, all you have to do is 36 divided by each side of the square (four sides in total) which gives you 9

Car A travels 20 mph faster than Car B. In the same time that Car A travels 252 miles, Car B travels 196 miles. Find their speed
RoseWind [281]

<u>Answer:</u>

A = 70

B = 90

<u>Step-by-step explanation:</u>

We know that Car A travels 20 mph faster than Car B.

Assuming the speed of Car B to be x and the speed of Car A to be x+20, we can write:

\frac{196}{x} =\frac{252}{x+20}

Taking the reciprocal of both sides to make x the subject:

196(x+20)=252x

196x+3920=252x

252x-196x=3920

56x=3920

x=70 ---> speed of Car A

Finding the speed of Car B: x+20 = 70+20=90

Therefore, the speed of Car A = 70 and the speed of Car B = 90.

Find the mean, the median, and all modes for the data in the given frequency distribution. (Round your answers to one decimal pl
kvasek [131]

Answer: Mean = 7.8

              Median = 9

             Mode = 2,9

Step-by-step explanation: <u>Mean</u> is the average value of a data set. Mean from a frequency table is calculated as:

E(X)=\frac{2(10)+3(9)+9(10)+11(7)+12(3)+15(4)+16(3)}{10+9+10+7+3+4+3}

E(X) = 7.8

Mean for the given frequency distribtuion is 7.8.

<u>Median</u> is the central term of a set of numbers. Median in a frequency table is calculated as:

1) Find total number, n:

n = 10 + 9 + 10 + 7 + 3 + 4 + 3 = 46

2) Find position, using: \frac{n+1}{2}

\frac{n+1}{2}=\frac{47}{2} = 23.5

Median is in the 23.5th position.

3) Find the position by adding frequencies: for this frequency distribution, 23.5th position is 9

Median for this frequency distribution is 9.

<u>Mode</u>  is the number or value associated with the highest frequency.

In this frequency distribution, 2 and 9 points happen 10 times. So, mode is 2 and 9.

Mode for this distribution is 2 and 9.
