4x+30=90
-30 -30
4x=60
X=15
So you would subtract 0.32 from 1.16 because it is the initial amount. Then divide what you get from that (0.84) by .21. You're gonna get .04- but that's not the answer because you have to add the initial ounce that is worth $0.32. So The answer is B
Answer:
73.5
Step-by-step explanation:
y=kx
where k is a constant
y=7
x=2
7=2k
k=3.5
what about when x=21
y=3.5*21
y=73.5
Answer: 14.6
<u>Step-by-step explanation:</u>
Draw a right triangle such that the building is perpendicular to the ground (which is where the shadow is cast).
Use Pythagorean Theorem to find the length of the shadow (x):
x² + 34² = 37²
x² = 37² - 34²
x² = 213
√x² = √213
x = 14.59
