The answer would be n=37 because…
40+n=77
subtract 40 on both sides, cancelling it out on the left side and 77-40=37 so:
n=37
Area = Bh, so 3 * (2/3) = 1
The area of each triangle, since there are two, would be half of the total area, so 1/2
You set up a proportion so: 12/x and 40/100
Cross multiply so 12 times 100 = 1200
and 40 times x = 40x
1200 divided by 40 = 30 minutes total
You know that he already know he spent 12 minutes doing it so
30 - 12 = 18 more minutes
Answer:
$4779
Step-by-step explanation:
First you need to write an equation to model this situation. In this case it's f(x)=1000(1.12)^x. College usually lasts 4 years, so to find the total amount of money they need to budget, you need to find the sum of f(0), f(1), f(2), and f(3).
This is roughly equivalent to 1000+1120+1254+1405, which equals 4779.
Answer:
19
Step-by-step explanation:
f(x)=2(3^x)+1,
Let x=2
f(2)=2(3^2)+1
Exponents first
=2 (9) +1
Then multiply
=18+1
=19
