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.
Answer:
<u>Mika estimated the sum to be 216; the actual sum is 216.27.</u>
Step-by-step explanation:
Let's find the rounded sum and the actual sum, as follows:
Rounding each number to the nearest whole:
189.27 ⇒ 189
15.8 ⇒ 16
11.2 ⇒ 11
Sum = 189 + 16 + 11
Sum = 216
Actual sum:
Actual sum = 189.27 + 15.8 + 11.2
Actual sum = 216.27
<u>Mika estimated the sum to be 216; the actual sum is 216.27.</u>
W^2=80
W SQRT80
W=8.94 ANS.FOR THE WIDTH
L=3*8.94=26.83 ANS.FOR THE LENGTH
PROOF:
240=8.94*26.83
240=240
So we want to know the product of 0.0000012 and 3.65*10^8 in the scientific form. First we turn 0.0000012 to scientific form: 0.0000012=1.2*10^-6. Now we multiply: (1.2*10^-6)*(3.65*10^8)=1.2*3.65*(10^-6)*(10^8)=4.38*10^(-6+8)= 4.38*10^2. So the correct product is 4.38*10^2.
