Answer:

The equation that models the relationships between x, the number of hours Mark reads, and , y the number of pages of the book he reads is:

y=56x

Step-by-step explanation:

Given:

Mark reads 42 pages every \frac{3}{4} hour.

The number of hours is given by = x

The number of pages is given by =y

The equation can be modeled as:

y=mx+b

where m represents rate of change and b represents the y-intercept or the initial value.

Rate of change ==\frac{Change\ in\ y}{Change\ in\ x}=\frac{42}{\frac{3}{4}}=42\times \frac{4}{3}=56

The initial value b=0 as Mark starts reading from 0.

So, the equation is:

y=56x

andre [41]
<h2>Answer:</h2>

The score range for the smallest percent of students is:

                         400 to 700

<h2>Step-by-step explanation:</h2>

From the pie chart or circle graph that is provided to us the smallest percent of the students are 10%

( Since 10%  is smallest among 14%,42%,34% and 10%)

and we may observe that the smallest region is denoted  or represented by the dark blue region and the range of the score of blue region that is given to us is:

                  400 to 700

   Hence, the answer is:

                   400 to 700

There are 140 apples for every 91 cups of water how many apples are needed for every 1 cup of water
podryga [215]

Answer:

The number of apple for 1 cup of water is 1.5 apples

Step-by-step explanation:

Given as :

The number of cups of water = 91 cups

The number of apples for every 91 cups of water = 140

Let The number of apple for 1 cup of water = n

<u>Now, From unitary method :</u>

∵ For every 91 cups of water , the number of apple needed = 140

∴ For every 1 cup of water , the number of apple needed = \frac{140}{91}

I.e n =  \frac{140}{91}

or, n = 1.5 apples

The number of apple for 1 cup of water = n = 1.5 apples

Hence The number of apple for 1 cup of water is 1.5 apples Answer

What is the approximate side length of each square
alexandr1967 [171]

Answer: 9\ units

Step-by-step explanation:

You need to use the following formula for calculate the area of a square:

A=s^2

Where "s" is the lenght of any side of the square.

You know that the area of a mural is 81\ units^2. Then, you can substitute this area into the formula and solve for "s", in order to find the side lenght of the mural.

Therefore, this is:

81\ units^2=s^2\\\\s=\sqrt{(81\ units^2)}\\\\s=9\ units

How do you find the circumference, radius, and diameter in area?
lawyer [7]

Answer:

Sample Respond: Let's assume it's equal to 14 cm. Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm . You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² . Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm .
