In order to achieve maximum results from aerobic exercise, one’s heart rate at a certain level. a 35-yr-old woman with a resting heart rate of 80 beats per minute should keep her heart rate between 143 and 164 beats per minute while exercising. she check her pulse for 10 sec while exercising. what should the number of beats be ?

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

answerim :

n

step-by-step explanation:

im not sure but my dad knows

6 cars because if you have 8 and subtract 2 youll have 6 left over

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
