Monica's heart beat 225 times in 3 minutes. jordy's heart beat 360 times in 5 minutes.
whose heart beat at the faster rate and what was that rate?
a. monica had the faster heart rate of 72 beats per minute.
b. monica had the faster heart rate of 75 beats per minute.
c. jordy had the faster heart rate of 72 beats per minute.
d. jordy had the faster heart rate of 75 beats per minute.
worth 8 points!

If Monica's heart beat is 225 times in 3 minutes. 225 ÷ 3 = 75 beats per minute.

Jordy's heart beat 360 times in 5 minutes. 360 ÷ 5 =  72 beats per minute.

So your answer is B. Monica had the faster heart rate of 75 beats per minute.

Hope this helps. :)

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
