Answer:
Step-by-step explanation:
I don’t know
You should look to units of measure when setting up problems. when math is done correctly, the units cancel out just as numbers and variables do.
(miles / hr) * hr = miles
Speed = (miles / hr)
So if the Train W is traveling at x miles/hr
Then Train E is traveling (x+14) miles/hr
The combined distance they two trains travel is 320 miles
2x + 2(x+14) = 320
2x + 2x + 28 = 320
4x + 28 = 320
4x = 292
x = 292/4
x = 73 miles/hr
remember we set x as the speed for Train W
so Train E is going 73 + 14 = 87 miles/hr
Yes because it’s the same shape just reflected and rotated

1.
volume of cone=(1/3)hpir^2
h=6
r=9
v=(1/3)6pi9^2
v=2pi81
v=162pi
3.14=pi for problem
162 times 3.14=508.68
answer is D
2. 2=r, 24=h
v=(1/3)24pi2^2
v=8pi4
v=32pi
answer is D
3. 10=h
4=r
v=(1/3)10pi4^2
v=(1/3)10pi16
