V=s^3
SA=6s^2
so
125=v
125=s^3
cube root both sides
5=s
A=6(5)^2=6(25)=150 m^2
64=v
64=s^3
cube root both sides
4=s
A=6(4)^2=6(16)=96 m^2
ratio is
150:96=25:16
Answer:
x = 8
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to the exterior angle that's supplementary to the third interior angle:
7x + 6 + 22 = 9x + 12 add like terms
7x + 28 = 9x + 12 export like terms to the same side of the equation
28 - 12 = 9x - 7x
16 = 2x divide both sides by 2
8 = x
If you would like to solve for x: 3x - 24 = 81, you can do this using the following steps:
<span>3x - 24 = 81
</span>3x = 81 + 24
3x = 105
x = 105 / 3
x = 35
The correct result would be 35.
She has distributed the bracket incorrectly
(64 + 5) - 0.2(- 20 + 10)
= (69) - 0.2 (- 10)
=34.5 + 2
= 36.5
The answer is probably 30 or 60
