240(v+2.5)=1300-240v
240v+600=1300-240v
480v=1900
v=95/24
v-2.5=v-5/2
95/24-60/24=35/24
So the faster group travels at 95/24 mph (≈3.96 mph) and the slower group travels at 35/24 mph (≈1.46mph)
check...
240(95/24)=950 miles from the origin...
1300-240(35/24)=950 miles from the origin...
V = Volume of cylinder
B = area of base
h = height of cylinder
It turns out that
V = B*h
In a similar way to that of a cube
If we know that V = 84pi and h = 7, then we can plug those values into the formula above, and solve for B
V = B*h
84pi = B*7
84pi/7 = B*7/7 ... divide both sides by 7
12pi = B
B = 12pi
Therefore the base is 12pi square units

Answer:
23
Step-by-step explanation:
With f(4), we plug 4 into the function.
f(4) = 4² + 7
f(4) = 16 + 7
f(4) = 23
Answer:
h = yX -yr
Step-by-step explanation:
X=r-h/y
X - r = h/y
y*(X-r) = h
h = yX -yr
