Answer:
72 animals
Step-by-step explanation:
Let d = dogs
d+d25% = cats
Changing to decimal form
d+.25d= cats
d(1.25) =cats
There are 40 cats
d(1.25) =40
Divide each side by 1.25
1.25d/1.25 = 40/1.25
d =32
There are 32 dogs and 40 cats
The total number of animals
32+40 = 72
x = total value of merchandise sold (in dollars)
y = take home pay (in dollars)
Job A: y = 0.15x + 750
Job B: y = 0.20x + 675
We want to know when job B's pay will be larger than job A's pay. So set the expression for job B larger than job A, solve for x
0.20x + 675 > 0.15x + 750
0.20x - 0.15x > 750 - 675
0.05x > 75
x > 75/0.05
x > 1500
Answer: Miranda must sell more than $1500 worth of merchandise to have job B pay more than job A.
Answer:
A) 300 cm2
Step-by-step explanation:
First you have to find height
use Pythagorean theorem: a2 + b2 = c2
h2 + 64 =289
h2 = 289-64
h2 = 225
h= 15
now the area
A = a * h
A = 20 * 15
A = 300 cm2
