Answer:

Step-by-step explanation:

60 minutes is one hour, which is all the way around the outside of the clock one time.  This distance is represented by the circumference of a circle, assuming that the clock is in fact circular.  The formula for the circumference of a circle in terms of the radius is

C=2\pi r

Our radius is 7, so the distance around the outside of that particular clock (and how far the minute hand travels if it goes around the clock one time) is

C=2\pi (7) or

C = 14π

If you want the decimal equivalency for that, multiply in pi as 3.1415 and round to whatever place you need.  In decimal form, that is

C = 43.9 inches

saveliy_v [14]

Answer:

F = $13,802.31

she can finance $13,802.31 with this loan.

Step-by-step explanation:

Given;

Rate r = 7% = 0.07

Time t = 4 years

Payment per month MP = $250

Number of months per year n = 12

This can be solved using compound interest for future value series formula;

F = future value

F = MP(((1 + r/n)^(nt) - 1)/(r/n))

Substituting the given values, we have;

F = $250(((1 + 0.07/12)^(12×4) - 1)/(0.07/12))

F = $13,802.31

A pizza company charges $8 for a large pizza and a $5 delivery charge. Write an equation that gives the
cupoosta [38]
8p +5 = $29
The above is the equation

If you want to know how many pizza were ordered then you subtract 5 from each side of the equal sign then you would have 8p=24 then divide by 8 on both sides of equal sign . p= 3 ; so 3 pizzas were order plus a charge of $5 for delivery.
