Answer:

C = km

k = 95

C = 665

Step-by-step explanation:

Calories burned varies directly to miles run.

Let

C = calories burned

m = miles

C = km

Dustin burns 190 calories for every 2 miles he runs

C = 190

m = 2

C = km

190 = k2

Divide both sides by 2

k = 95

equation for the direct variation.

C = km

Find how many calories Dustin will burn after running 7 miles.

C = ?

m = 7

k = 95

C = km

C = 95 × 7

= 665

Muna claims that the expression (8)(16) + (8)(12) + (16)(12) represents the
aivan3 [116]

The surface area of a right rectangular prism is the amount of space on it.

Muna's claim is incorrect

<h3>How to determine the surface area?</h3>

The surface area of a right rectangular prism is calculated as:

A = 2 * (lw + lh + wh)

So, we have:

A = 2 * (8 * 16 + 8 * 12 + 16 * 12)

The above expression implies that Muna's claim is incorrect

seropon [69]

Answer:

t ≥ 96   test score must be 96 or greater

Step-by-step explanation:

Let t - score on his third test

   (75 + 81 + t) ÷ 3 ≥ 84

⇒ (75 + 81 + t) ≥ 84 x 3

⇒ (75 + 81 + t) ≥ 252

⇒ 156 + t ≥ 252

⇒ t ≥ 252 - 156 ≥ 96
