Answer: The radius is 5. Hopefully this helps. :)
Step-by-step explanation:
V = π r2 h 125/5=25
125π = π r2 5 r2=25
125π= π*5^2*5 r=5
Answer:
t=4
Step-by-step explanation:
Use the distributive property first on the left side (multiply 2 by t and 2 by 1). This leaves you with 2t+2=10. Then you just have a multistep equation. Subtract 2 from both sides (2 cancels out on the left side and you are left with 8 on the right side). Equation now looks like 2t=8. Then, you divide by 2 on both sides to isolate the t and you get 4.
Answer:
7.5s
1.6666 repeating or 1.67 m/s²
Step-by-step explanation:
the equation you have to use is Vfinal=Vstart+acceleration•time
(I'm gonna simplify to Vf=Vs+at)
so you gotta rework it for the two equations
for the first equation you need time so take Vf=Vs+at and subtract Vs on both sides to get Vf–Vs=at
then divide acceleration on both sides to get t=(Vf–Vs)/a
for the second problem equation need the equation a=(Vf–Vs)/t (just divide time on both sides instead of acceleration)
so you the plug in
(I don't put the units in to the problem unless needed)
1. t=(Vf–Vs)/a to t=(0–30)/-4.0
t= -30/-4.0
t=7.5 seconds
2. a=(Vf–Vs)/t to a=(10–0)/6.0
a= 10/6.0
a= 1.67m/s²
(I'm assuming the that for number two they started at rest so it would be 0m/s for velocity start)
Proportion is an equation in which two ratios are set equal to each other.
