Answer:
A. 8/100+2/10
Step-by-step explanation:
8/100+2/10= 7/25
7/25(in decimal form)= 0.28
Answer:
1/16
Step-by-step explanation:
-1/4*-1/4
= -*- = +
= 1/4*1/4
=1/16
Answer:
2,600
Explanation:
Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
N + 9 > 16 or n + 3 < -6
- 9 - 9 - 3 - 3
n > 7 or n < -9
Solution Set: (7, ∞) or (-∞, -9), {x|x > 7 or x < -9}
50:1 scale drawing -> Both sides of the garden is shrinked by 50 times.
We can calculate the area of the shrinked scale drawing : 12 x 10.5 = 126 (cm2)
Since both sides are shrinked by 50 times -> The real area get shrinked by 2500 times.
So, we can find the real area : 126 x 2500 = 315000 (cm2)
