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
Area of a rectangle can be found with the formula:
Area = length × width
If Sarah knows the length, she should know the width in order to find out the area of the rectangle.
Answer: width
Hello :
<span>the numbers are : x , y
x - y = 4...1)
xy = 96...(2)
by (1) : x = y +4...(*)
subsct in (2) : (y+4) y = 96
y² +4y -96 = 0
(y² +2(2y) +2²) -2² -96 = 0
(y+2)² -100 =0
</span>(y+2)² <span>= 10²
y +2 = 10 or y+2 = -10
y = 8 or y = -12 ( refused : x is positif)
y = 8
</span>subsct in (*) : x = 8+4 = 12
<span> the numbers are : 12 and 8
12-8 = 4 and 12×8 = 96</span>
