Martin burns 360 calories running for 30 minutes. Paul burns 165 calories for every 15 minute he runs. If Kara runs for 20 minut
Yanka [14]

Answer:  She would have to burn between 220 and 240 calories per minute to have a calorie burn rate between those of Martin and Paul.

Step-by-step explanation:

Martin:

360 calories / 30 min = 12 calories/min

Paul:

165 calories / 15 min = 11 calories/min

Kara:

Needs to burn between 11 and 12 calories/min, so we'll calculate the range:

11 calories/min x 20 min = 220 calories (minimum # calories she can burn)

12 calories/min x 20 min = 240 calories (maximum # calories she can burn)

What is the value of r (3,4), (-1,r),m=-3/4
Llana [10]

To find the value of r

We will follow the steps below

Usinf the equation of a slope:

slope(m) =

m=\frac{y_2-y_1}{x_2-x_1}

from the question given;

m= -3/4

x₁ = 3

y₁=4

x₂=-1

y₂=r

substituting the values into the slope formula

\frac{-3}{4}\text{ = }\frac{r-4}{-1-3}

we can now simplify and then solve for r

\frac{-3}{4}\text{ = }\frac{r-4}{-4}

cross-multiply

-3 x -4 = 4(r-4)

12 = 4(r-4)

Divide both-side of the equation by 4

\frac{12}{4}\text{ = }\frac{4(r-4)}{4}

3 = r - 4

add 4 to both-side of the equation

3+4 = r-4+4

7 = r

r=7

Therefore the value of r is 7
