A survey was taken of students in math classes to find out how many hours per day students spend on social media. The survey results for the first-, second-, and third-period classes are as follows: First period: 2,4,3,1,0,2,1,3,1,4,9,2,4,3,0 Second period: 3.2.3.1.3, 4.2, 4.3, 1.0.2, 3, 1.2 Third period: 4,5, 3, 4, 2, 3, 4, 1, 8, 2, 3, 1, 0, 2, 1, 3 Which is the best measure of center for second period and why?​

The amount of water in the tank represented by the equation as:

y = 2m + 6, where y is the total amount of water in the tank, m is the number of minutes.

A linear equation is defined as an equation in which the highest power of the variable is always one.

Let y represent the total amount of water in the tank and m represent the number of minutes.

We can model the amount of water in the tank using the equation:

y = 2m + 6

This equation states that the total amount of water in the tank (y) is equal to the rate of filling (2 gallons per minute) multiplied by the number of minutes (m), plus the initial amount of water in the tank (6 gallons).

For example, if we let m = 5, then y = 2 × 5 + 6 = 16, which means that after 5 minutes, the tank will contain 16 gallons of water.

Answer: 88.8 m , 59.2 m

Step-by-step explanation:

Given

Breadth is [tex]\frac{2}{3}[/tex] of length

Suppose length is x m

So, breadth is   [tex]\dfrac{2}{3}x[/tex]

Perimeter is given by [tex]P=2(L+W)[/tex]

Putting values

[tex]\Rightarrow 296=2(x+\dfrac{2}{3}x)\\\\\Rightarrow 296=2(\dfrac{5}{3}x)\\\\\Rightarrow x=\dfrac{296\times 3}{10}=88.8\ m[/tex]

Length L is [tex]88.8\ m[/tex]

width W is [tex]\frac{2}{3}x=59.2\ m[/tex]

Answer:

The correct answer to a is 3 1/2 same answer for the other answer.

Answer:

a. 7/2  OR  3 1/2     Either answer should be acceptable

b. 82/15   OR  5 7/15   Either answer should be acceptable

Step-by-step explanation:

a. 5 3/4 =  so first multiply the denominator, 4, by the whole number 5 so 4 x 5 is equal to 20. Add this to your numerator, 3.

20 + 3 = 23 so the new fraction is 23/4

Same thing with 2 1/4     4 x 2 = 8 + 1 = 9    9/4

23/4 - 9/4 = 14/4 simplify this to 7/2

b. Same process here:

7 2/3      3 x 7 = 21 + 2 = 23      23/3

2 1/5       5 x 2 = 10 + 1 = 11        11/5

This time, we need a common denominator

3 x 5 = 15

5 x 3 = 15

23/3 x 5/5 = 115/15

11/5 x 3 = 33/15

115/15 - 33/15 = 82/15

Answer:

43.5625 kilometers

Step-by-step explanation:

hi!

To solve this problem, you have to take note of the important information which is:

- 10.25 km/hour

- 4.25 hours

- how far did she travel?

To answer the question, you need to take Mia's hourly rate (10.25 km PER hour) and multiply that by how many hours she rode her bike for (4.25) which equals 43.5625 kilometers

10.25*4.25 = 43.5625 kilometers

If we were to take a cross-section of our planet on the equator, we would get a circle. So, the circumference of this circle is the distance one would have to travel to go around the earth. The formula for the circumference of the circle is 2 x r x pi. The radius of the Earth is r, and pi is approximately 3.1415. So, the circumference is 2 x 6370 x 3.1415, which equals 40 029 km, or approximately 40 thousand kilometers.

Answer: 12,740π. If you use pi as 22/7, you get 40040. If you use pi as 3.14, you get around 40004, so the circumference is basically around 40000
