Hi! To find the amount of simple interest earned, we can divide the amount earned in interest by the amount in the savings account. 20/500 is 0.04. To get this in percent form, multiply by 100 to get 4. Lily's savings account received an interest rate of 4%.
Answer: 8/15, 15/8
Step-by-step explanation:
By the Pythagorean theorem, the length of the unknown side is
So, the tangents of the acute angles are 
If 12 is 20%, then 24 is 40%, then 36 is 60%, then 48 is 80%, then 60 is 100%
So there are 60 questions on the test.
Answer:
$69.17
Step-by-step explanation:
.065 x 64.95 ≈ $4.22
$69.17 + $4.22 = $69.17
Brainliest would be appreciated but not required :)
ANSWER:
As the above angles are corresponding, so they must be equal.
So, 17x - 4 = 12 + 5x
17x - 5x = 12 + 4
12x = 16
x = 16/12
x = 4/3.
