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>

Answer:

845

Step-by-step explanation:

Because they are similar triangles you can find the scale factor first.

395/553 is the scale factor

(395/553)*280=200

(395/553)*350=250

200+250+395 = 845

Question: State whether each table of values represents a function​
Mashcka [7]

Answer:

Please check the explanation.

Step-by-step explanation:

  • As we know that the values in the table represent a function​ only if there there is only 1 input for every output.

Given the table 1

x              y

-12           2

-10           10

0              -2

5              -6

8               -11

15              -15

From the table, it is clear that for each input there exists a unique output.

i.e.

According to the given table,

y = 2 at x=-12

y = 10 at x=-1 0

y = -1 at x=0

y = -11 at x=8

y = -15 at x=15

From the table, it is clear that for each input x, it has a unique output y.

Hence, table 1 is a function.

Given the table 2

x              y

9            -18

-20           0

-6              1

-17              16

9                17

11              19

This table does not produce a function, because the input x=9 produces two outputs.

i.e.

at x = 9, the y = -18

at x = 9, the y = 17

Therefore, the table 2 does not represent a function.
