After an exercise, Ali and Ben measured their heart rates. The ratio of their heart rates was 15:17 Bens heart beats 18 times pe

skelet666 [1.2K]

Answer:

Ali's heart rate is 135 times per minute.

Step-by-step explanation:

Let Ali's heart rate be denoted by x times per minute.

It is provided that Ben's heart beats 18 times per minute more than Ali.

The ratio of their heart rates was 15:17.

That is:

$\frac{15}{17}=\frac{x}{x+18}$

Solve for x as follows:

$\frac{15}{17}=\frac{x}{x+18}$

$15(x+18)=17x\\15x+270=17x\\2x=270\\x=135$

Thus, Ali's heart rate is 135 times per minute.

viva [34]

Answer:

p = 14 inches

Step-by-step explanation:

using either the sine or cosine ratios

using the sine ratio and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{7}{p}$ = $\frac{1}{2}$ ( cross- multiply )

p = 14

Find the slope of the line passing through the points (-2,3) a and (-9,6).

larisa [96]

<h3>Answer: Slope = -3/7</h3>

===================================================

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (6-3)/(-9-(-2))

m = (6-3)/(-9+2)

m = 3/(-7)

m = -3/7

This means each time you go down 3 units, you go to the right 7 units.

Slope = rise/run = -3/7

rise = -3 and run = 7
