112-88 = 24
they save $24 per month
so 650/24 = 27.083
so it will pay for itself in 27.083 months, round up to 28 months
Answer:
<em>500πx³y³z³ </em>
Step-by-step explanation:
Volume of a sphere = 4πr³
r is the radius of the sphere
Given
Diameter of the sphere = 10xyz mm
Radius = diameter/2
Radius = 10xyz/2
Radius = 5xyz
Substitute the radius into the formula
Volume of the sphere = 4π(5xyz)³
Volume of the sphere = = 4π(125)x³y³z³
Volume of the sphere = 500πx³y³z³
<em>Hence the volume of the sphere is 500πx³y³z³ mm³</em>
The correct answer is 30+100u. Hope this helps!!
Answer:
−6.7 + (−2 1/ 5 )
Step-by-step explanation:
−6.7 + (−2 1/ 5 )
-12 degrees.
Each hour, the temperature dropped by 3 degrees so it'd look like:
-3
-6
-9
-12
