Mathematics

Answer:

A)

y =  \frac{10}{3}x

B) 240 pages

Step-by-step explanation:

From the table, he can read 20 pages in 6 minutes and 15 paged in 50 minutes.

The unit rate can be found using

m =  \frac{change \: in \: y}{change \: in \: x}

m =  \frac{50 - 20}{15 - 6}

m =  \frac{30}{9}  =  \frac{10}{3}

Using the point (6,20) and the unit rate we can find the equation using

y-y_1=m(x-x_1)

y - 20 =  \frac{10}{3}(x - 6)

y=\frac{10}{3}x - 20 + 20

y =  \frac{10}{3}x

B) When x=72 minutes we substitute

y =  \frac{10}{3} \times 72

y = 10 \times 24 = 240

17. The length of a rectangle is 12 in, and the perimeter is 56 in. Find the width of the rectangle.
Ivahew [28]

Answer:

Step-by-step explanation:

P = 2(L + W)

P = 56

L = 12

now sub...we are looking for w

56 = 2(12 + W)

56 = 24 + 2W

56 - 24 = 2W

32 = 2W

32/2 = W

16 = W <==== the width is 16 inches

check...

P = 2(L + W)

56 = 2(12 + 16)

56 = 2(28)

56 = 56 (correct)

Choose ALL that apply
HACTEHA [7]

The ratios that have a unit rate of 5 will be:

6 1/4 kilometers to 1 1/4 minutes.

1 kilometer to 1/5 minutes

1/3 kilometers to 1 2/3 minutes

<h3>How to calculate the value?</h3>

The ratios will be:

1. 6 1/4 to 1 1/4

= 6.25 : 1.25

= 5

2. 4 1/2 to 2

= 4 1/2 / 2

= 2.25

3. 4/5 to 5 minutes

4. 1 kilometer to 1/5 minutes

= 1 : 1/5

= 1 / 0.2

= 5

5. 3 1/10 : 3/10

= 10

6. 1/3 : 1 2/3

= 5

Therefore, the correct options are 1, 4 and 6.
