Answer:
1 hour
Step-by-step explanation:
Each graph shown lasts for 1/2 hour / 30 minutes
Answer:
<u>Volume=2.2*10^10 km^3
</u>
Step-by-step explanation:
Given
Diameter of moon=d=3476 km
The formula for the volume of sphere is:
V=4/3 πr^3
As it can be clearly seen that the formula uses radius, and we are given diameter. So we have to find the radius first
So,
radius=r=d/2
=3476/2
=1738 km
Now putting the value of r and pi in the formula:
V=4/3*3.14*(1738)^3
=12.56/3* 5249879272
= 21979494552.106
Rounded off to two significant digits:
<u>Volume=2.2*10^10 km^3
</u>
Answer:
B
Step-by-step explanation:
- 9.2(8x - 4) + 0.7(2 + 6.3x) ← distribute parenthesis
= - 73.6x + 36.8 + 1.4 + 4.41x ← collect like terms
= -73.6x + 4.41x + 36.8 + 1.4
= - 69.19 + 38.2
