Find the percent of discount (Just type in the number).<br> $55 on sale for $46.75
Rom4ik [11]

Answer:

15%

Step-by-step explanation:

Given,

Original price = $55.00

Discounted price = $46.75

Discount  = $55.00 - $46.75 = $8.25

Percent Discount = (Discount / Original price) x 100%

= (8.25 / 55.00) x 100%

= 0.15 x 100%

How tall is the flag pole (please give explanation too)
Tpy6a [65]

Answer:

  22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

  h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

  h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

  h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.

n = 12

a = 15

d = - 4

an= 15 + (n - 1)*d

a12 = 15 + 11*(-4)

a12 = 15 - 44

a12 = - 29
