A = LW
A = 320
L = 5W
320 = W(5W)
320 = 5W^2
320/5 = W^2
64 = W^2
sqrt 64 = W
8 = W
L = 5W
L = 5(8)
L = 40
so the length (L) = 40 cm and the width (W) = 8 cm
P = 2(L + W)
P = 2(40 + 8)
P = 2(48)
P = 96 <=====
Answer:
<h2>4/5</h2>
Step-by-step explanation:
Look at the picture.
We need a hypotenuse length.
Use Pythagorean theorem:
We have
Substitute:
For the sine we have:
Substitute:
Answer:
1. 8/35
2. 13/35
Explanation:
You add the numbers in the parentheses first, then you multiply
1. 1/5 + 3/5 = 4/5
4/5 * 2/7 = 8/35
———————————
2. 1/5 + 3/5 * 2/7
You would multiply 3/5 and 2/7 first
1/5 + 6/35
Then you find a common denominator
1/5 = 7/35
Then you add 7/35 and 6/35
7/35 + 6/35 = 13/35
