Answer:

finding area formula of a circle:

πr^2 (pie r (radius) squared)

Pie could equal: 22/7 or 3.14

Use 3.14 most likely,

Given information

Radius is: 12

(needs to be squared)

12 x 12 = 144

144 x 3.14 <------ (pie or π) = 452.16

452.16 rounded to the nearest hundredth is:

452.16 miles. (doesn't have a thousandths place so we can't really round but we should assume the number by itself)

Sidana [21]

Answer: 10 hours

Step-by-step explanation:

Given

Slow fix auto charge $28 for parts and $48 per hour of labor

We work charge $59 for parts and $44.90 per hour of labor

Suppose both works for x hours

Cost of Slow fix= \$(28+48x)

Cost of We work= \$(59+44.90x)

When these costs are the same

28+48x=59+44.90x\\3.1x=31\\x=10\ hours

19 4/12 + 17 2/11 - 16 6/9 =
SOVA2 [1]

Answer:

19 28/33

Step-by-step explanation:

lets work out the whole number parts first:

= 19 + 17 - 16 = 20.

4/12 + 2/11 - 6/9

= 1/3 + 2/11 - 6/9

Find the LCM of the denominators:

3 = 3

11 = 11

9 = 3*3

- so the LCM is 3*3*11 = 99.

So we have:

33/99 + 18/99 - 66/99

= 51/99 - 66/99

= -15/99

= -5/33

So the answer is  20 - 5/33

= 19 28/33

You just had to subtract 5/33 from 20.

The lines on the outside simply means "absolute value". This just takes any negative number and makes it positive. In this case, 15-4 is already positive so the answer is just positive 11.
