Answer:
10 feet
Step-by-step explanation:
this is a Pythagorean Theorem Problem
A rectangle has 4 right angles. The diagonal cuts the table in 1/2 into 2 triangles.
Formula
c^2 = a^2 + b^2
Givens
a = 6
b = 8
Solution
c^2 = 6^2 + 8^2 Substitute into the formula. Expand the givens
c^2 = 36 + 64 Add on the right
c^2 = 100 Take the square root on both sides
sqrt(c^2) = sqrt(100)
c = 10
You could use the formula a^2+b^2=c^2. So the answer is D.4.
Step-by-step explanation
They sold $480 of tshirts, the ratio is 480;20, simplified to 24:1.
One shirt is $20, but $4 is the amount taken from 20 for the equipment.
Multiply $24 by the $4 taken for the equipment. (Equals $96)
They make 4/20 (1/5) of the the sales as a profit for equipment.
Multiply 1/5 by 480 and you will get $96 as the club's profits.
