First, convert 625 revolutions per minute to revolutions per hour: 625*60=37500 revolutions per hour

Next you can simplify 88 feet for 11 revolutions to 8 feet per revolution.

To find how many feet per hour you are travelling, multiply 37500 by 8 ft., which results in 300000 feet per hour.

Then you have to convert 300000 ft. per hour to mph. There are 5280 feet in a mile, so divide 300000 by 5280 to get approx. 57 mph.

Basile [38]

Answer:

V(t)=0.0112\pi t^{2}

Step-by-step explanation:

we have

V(r)=0.07\pi r^{2} -----> equation A

r(t)=0.4t -----> equation B

To find out (V of r)(t) substitute equation B in equation A

V(r(t))=V(t)

V(t)=0.07\pi (0.4t)^{2}

V(t)=0.07\pi (0.16)t^{2}

V(t)=0.0112\pi t^{2}

-(7-9)z-6z=8(-6+2) solve for z
Sergeeva-Olga [200]

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8
