Answer:
Step-by-step explanation:
If the new height is 338m and the helicopter decended 127m to get to that new height then the original height is simply the sum of them both.
H = 338m + 127m
H = 465m

Answer:
Step-by-step explanation:
Line d slope is 8/7, therefore the perpendicular is -7/8
Answer:
1.
a) 5cm
b) 16cm
c) 25cm
d) 124cm
2.
a) 4m
b) 6m
c) 10m
d) 26m
3.
a) 2km
b) 4km
c) 11km
d) 28km
Step-by-step explanation:
When you have a number and it tells you to round it to the nearest cm (m, km etc.), it means you just have to make it a whole number (integer) instead of a decimal by rounding it up or down.
To tell whether you round up or down, you look at the number after the decimal place and if it is under 5, you round down but if it is 5-9 you round up.
For example,
If we had 20.3 (not one of the questions) you would round it down to 20 because the 3 after the decimal place is smaller than 5.
However, if we had 24.7 you would have to round it up because the 7 is from 5-9.
Hope this helps :)
A = 4πr² Divide both sides by 4π
A / 4π = r² Find the square root of both sides
√(A / 4π) = √(r²) Cancel out the square with the square root
√(A / 4π) = r Switch the sides to make it easier to read
r = √(A / 4π)
