Answer:
the total surface area of the rocket: 1978.2 
Step-by-step explanation:
Given that :
- A rocket in the shape of a cone
- The aslant height: 15m
- The base diameter: 12m <=.> Radius: 6m
- The height: 42
So the surface area of a a cone with about the base area because it is attached to a cylinder:
= π*r*l = 3.14*6*15 = 282.6
The area of the cylinder is: 2*π*r*h+pi*
(without the top part of it)
= 2*3.14*6*42 + 3.14*
= 1695.6
At the end, the total surface area of the rocket:
1695.6 + 282.6 = 1978.2
Answer:
Step-by-step explanation:
Let total x black and y brown shoes are sold in a week
So total number of shoes sold in a week is = x+y
It is given that 
of all shoes sold are black
So 
So the number of brown shoes sold in a week in terms of black shoes are x/2
Answer: D-18 years, Joan-41 years
Step-by-step explanation:
Given
The Sum of Debbie and Joan's age is 59
Take x and y as the age of Debbie and Joan
In 5 years, twice Debbie's age will be equal to Joan's age
Also, 
solving these two equations we get
Well it is distributive but you don't but the multiplication sign by the 8 with the parenthesis so it would be 8(12*5) and then you do 8*12 which is 96 and then 8*5 which is 40 and then add 96+40
Precipitation is when liquid falls from the atmosphere and reach the surface of the Earth. Condensation is when water vapor changes back into water (in liquid form).
