Answer:

20.833 feet

Step-by-step explanation:

The light reflects off the mirror at the same angle that it hits it at.  So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.

Therefore, we can write and solve a proportion.

h / 10 = 6.25 / 3

h = 20.833

The beam is 20.833 feet tall.

Which of the following pairs of items is a better​ buy?
Bas_tet [7]

Answer:

a. 6Pack of paint brushes for $12.99

b. 5 classes for $64.99

c. 12 pack of paper plates

Step-by-step explanation:

a.

I could buy a 6 pack of paint brushes for $ 12.99

or

buy 6 individual brushes for the price of $ 2.19 each.

6 x $2.19 = $13.14

first option is cheaper

b.

10 classes for s total of $150

$150 ÷ 10 = $15 (price per class)

5 classes for $64.99

$64.99 ÷ 5 = $12.998 (price per class)

c.

12 pack of paper plates for $2.29

25 pack for $4.99

$2.29 ÷ 12 = $0.1908 (price of one plate)

$4.99 ÷ 25 = $0.1996 (price for one plate)

Do you multiply area or add it
pogonyaev
It's the formula. Base times height.
For example: if 50 is the base and 10 is the height, just multiply them both.
50 x 10 = 500. And I don't think you add area-that's for finding the perimeter
