Answer:
12 years
Step-by-step explanation:
Simple interest formula:
where
I = interest,
P = principal,
r = rate (as decimal),
t = time
In your case,
P = $616
I = $1,007.78 - $616 = $391.78
r = 0.053
t - unknown, so
Using remainder theorem, we get:
Substitute t = 5 into the equation:
Thus, we get a remainder of 93 or (A)
We are asked to simplify the expression
,
what we do is, we form a single fraction where the numerator is the product of the numerators, and the denominator is the product of the denominators, that is:
simplify the common numbers and terms in the numerator and denominator:
Answer:
Tan(theta)=opposite/adjacent
Tan(31)=x/10
(Tan(31))10=x
X=6.0086
Answer: 12%
Step-by-step explanation:
Total number of people in 6th grade: 70+80 = 150
Total numbers of lefties: 11 + 7 = 18
Percent:
18 ÷ 150 = 0.12
0.12 x 100 = 12
