We know that
circumference=pi*D
where D is the diameter
diameter=4 ft
circumference=4*pi ft
if one revolution is -------------> 4*pi ft
1320 rev-------------> x
x=1320*4*pi-----> x=5280*pi ft/hout

convert ft to miles
1 mile-----------> 5280 ft
so
5280*pi ft----------> is pi mile
5280*pi ft/hour------> is equal to pi mile/hour

the answer is the option
<span>a. pi</span>

A college theater charges $5 handling fee. tickets cost $58. what would the slope be

schepotkina [342]

The slope would be 58.

Slope = (change in y) / (change in x)

That relationship is established by the fixed cost of each ticket ($58). The handling fee is a constant that would shift the curve upward by $5, but would have no effect on the slope of the line since it is completely independent from the number of tickets being purchased (x).

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

marta [7]

Answer:

Therefore the results from adding the equation in this system is

$7x=-35$

Step-by-step explanation:

Given:

Equations as

$11x-3y=-17$ .......................1

$-4x+3y=-18$ .......................2

To Find :

Result when adding equation 1 and 2 = ?

Solution

On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18) as shown below

11x - 3y = -17

-4x + 3y = - 18

-------------------------------------------

7x + 0 = - 35

---------------------------------------------

Therefore the results from adding the equation in this system is

$7x=-35$
