If the sale was for 30% off, then she paid 70% of the regular price

100%-30%=70% or 0.70

72*0.70=$50.40

Answer= $50.40

What you would want to do is make 30% into a decimal which is 0.30. Then divide  72 by 0.30 and get the answer

klemol [59]

Answer:

100°

Step-by-step explanation:

the total of all angles around O on one side of AD is 180° (as that would represent a half-circle).

and the sum of the arc angles AB + BC + CD covers the whole 180°.

so, we have

180 = 55 + BC + 25

180 = 80 + BC

BC = 100°

Your co-worker, Amanda, and you are reliving your high school athletic "glory days" during a coffee break. She played basketball
topjm [15]

Answer:

Our score = 0.60, Amanda's score = 0.25

Step-by-step explanation:

For Amanda

μ = 15 , σ = 4

z- score for X = 16 is (From z table)

z = (X - μ)/σ = (16 - 15)/4 = 0.25

For us

μ = 310 , σ = 25

z score for X = 325 (From z table)

z = (325-310)/25 = 0.60

Since our z score is better than Amanda's z score, we can say we did better

Solve the equation: 5x + 7= 7x +23
olga nikolaevna [1]

Answer:

x = -8

Step-by-step explanation:

1)  5x + 7= 7x +23

Move the terms

2)  5x + 7 -7x = 23

Collect like terms

3)  5x -7x = 23 - 7

Calculate

4)  -2x = 16

Divide both sides by <em>-2</em>

5)  x = -8
