You will want to round to 977.259
look at the number to the right of 9, it is 8, and 8 > 5. IF the number is 5 or greater, round up.
so your answer is 977.260
hope this helps
Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)
The answer is A) 1 over 2, because you take the original point such as A and go either up or down, and left or right to get to A prime
To solve the given problem
We can consider,
30% are girls of 30 people
70% are boys in 30 people
In order to get the number, we just multiply the total number
of people with the percentage of the designated target populace.
<span><span>1. </span>30 x 0.3 =
9 girls</span>
<span><span>
2. </span>30 x 0.7 =
21 boys</span>
<span><span>
3. </span>21 boys + 9
girls = 30 people</span>
Hence, there are 21 boys.
For this problem, let's assign variable x to the value of the actual weight. The recommended weight is the central value of the range. So, the variation must be 20 grams below and above the recommended weight. The equation would be:
Actual weight = |Recommended weight +/- 20|
x = |430 +/- 20|
