Step-by-step explanation:
( x-2y=12)5
5x-10y=60
- 5x+3y=-44
____________
13y=-104
y=-104/13
You would divide miles to hours amd get 57.5
19500 times because
5 times 26 = 130 (how many minutes)
and
now just multiply how many minutes (130) times how many heart beats per minute (150) to get 19500
Answer: Height = 41 in
Step-by-step explanation:
Alrighty, I was trying to dodge this question but I guess I'll have to split my brain cells.
To find the Height we can turn the information we have into an equation
15,577.54 = 3.14 * 11 ^ 2 * h
we do some distrubutive property
15,577.54 = 3.14 * 121 * h
15,577.54 = 379.94 * h
15,577.54 = 379.94h
divide by 379.94
H = 41
THE HEIGHT IS 41 YAY ( My head hurts )
X and y vary inversely:
y=k/x
y=8/3 when x=8
8/3=k/8
Solving for k:
8(8/3)=k
64/3=k
k=64/3
y=k/x
y=(64/3)/x
y=(64/3)(1/x)
y=64/(3x)
when x=4→y=64/(3x)=64/(3(4))→y=16/3
Answer: Second Option y=64/(3x); 16/3
