Answer:
42 candles
Step-by-step explanation:
Firstly, we need to find the surface area of the pyramid used. This can be obtained by finding the area of the base, multiplied by the height of the pyramid.
The area of the base since it is rectangle is L * B and that is 5 * 2 = 10cm.sqr
The volume of the pyramid is A * h and that is 10 * 12 = 120cm.cub
To fInd the number of candles used , we simply divide the volume of wax by the volume of a candle.
That is 5040/120 = 42 candles
Answer: So our two integers are 17 and 45.
Step-by-step explanation:
The two integers are 17 and 45, See how we got it. X+Y=62. Substitute our first expression here for y, we have X+2X+11 =62.
The answer to this question is 20 mph and 24 mph

Answer:
x = 125/7 , y = -11/3
Step-by-step explanation:
7x - 9y = 29
7x + 2y = - 15
- - + (subtracting)
__________
0 - 12y = 44
y = 44/-12
y = - 11/3
Putting y in first equation,
7x - 9 (-11/3) = 29,we get
x = 125/7 or 17.8
Hope it helps!
