Please help I rlly need it
kozerog [31]

Answer:

a)78

b)82.95

Step-by-step explanation:

To get the amount something is marked up you just need to multiply it by

1+0.(the%)

so in this case you multiply 60 by 1.30 to get 78

To get a discount you just have to do the same but without the +1

so 88*0.15

should get you the discount amount (13.2)

which you subtract from the original number (88-13.2 = 74.8)

now to get sales tax you would multiply the 79 by 0.05 which is 3.95

and add that to the total of 78.75 since sales tax applies AFTER coupons

The distants around the edge of the pool is 38 feet. What is the area the pool with cover
kvv77 [185]

Answer:

114.93 ft

Step-by-step explanation:

\pi  = 3.14

Given formula to find the area:

\pi  * r^2

Find radius first:

Circumference = \pi  * 2 * r

The circumference in this situation would be 38 feet.

38ft = \pi  * 2 * r

38 ft = 3.14 * 2 * r

3.14 * 2 = 6.28

38ft = 6.28 * r

Since we need to find radius, do division to 38 by 6.28.

38ft / 6.28 = 6.05

Our radius is 6.05

Now back to the original formula which is:

\pi  * r^2

Substitute:

A = 3.14 * 6.05^2

6.05^2 = 36.6

A = 3.14 * 36.6

==> 114.93ft
