Answer:
60
Step-by-step explanation:
Simplify the following:
4×9^2/27×5
9^2/27×5 = (9^2×5)/27:
4×(9^2×5)/27
4×(9^2×5)/27 = (9^2×5×4)/27:
(9^2×5×4)/27
9^2 = 81:
(81×5×4)/27
81/27 = (27×3)/27 = 3:
3×5×4
3×5 = 15:
15×4
15×4 = 60:
Answer: 60
Answer:
60
Step-by-step explanation:
First we divide 5 from 20 then we get 4 so 4 x 15 would be 60.
Answer:
Step-by-step explanation:
Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.
Or 1260 =(n-2)x180
Dividing both sides by 180:
7=n-2
Adding both sides by 2 we have :
n=9.
Hence a nanogon will have the sum of interior angles as 1260°.
Answer:
the height depends on launch speed and body weight
Step-by-step explanation:
Cube root of (2x + 3) = 5
I think the best thing to do is to cube both sides
2x + 3 = 125
2x = 122
x = 61
We can check that:
cube root of (2x + 3) = 5
cube root of (2*61 + 3) = 5
cube root of (122 + 3) = 5
and the cube root of 125 does equal 5
so x = 61
