H^2 = 12^2 + 16^2
H^2 = 144 + 256
H^2 = 400
H = square root of 400 = 20
Answer:
The answer is y = 5.25
Step-by-step explanation:
-2.3 + 1.6y = 6.1
1.6y = 6.1 + 2.3
1.6y = 8.4
y = 8.4/1.6
y = 5.25
Answer:
D
Step-by-step explanation:
The area of a circle can be found using:
a=πr^2
We know that the radius is 10 meters. Therefore, we can substitute 10 in for r.
a=π*10^2
Evaluate the exponent
a=π*100
Multiply pi and 100
a=314.159265359
Round to the nearest tenth: there is a 5 in the hundreth place, which indicates we round up the 1 in the tenths place to a 2.
a=314.2
The area is 314.2 square meters, or choice D
Answer:
It's very simple, all you have to do is round the place that is underlined. So for the first question, 6,9<u>9</u>5,000, the 3rd number there is underlined. (Which is the number 9) So you will have to round to the nearest ten thousand. The answer for number 1 is 7,000,000.
