The formula for desnity is d= m/v (mass over volume), so
1) 0.18 = 240/v Plug in the numbers you have (0.18 being the density and 240 being the volume)
2) 0.18(240) = 240/v(240) multiply 240 on each side to get rid of the 240 on the right side of the equation.
3) 43.2 = m
So, the formula would be d=m/v and m= 43.2
1.02 = 1 + 0.02
n is 4 you can tell by the 4t = nt exponent
0.02 * 4 = 0.08 interest rate as decimal
B. 8% interest
A. 4th down from top
3.2x-9.6=-.4x+1.2
3.2x=-.4x+10.8
3.6x=10.8
X= 3
The width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.
<u>Explanation:</u>
Given:
Two rectangles are proportional.
Length and width of 1 rectangle = 6 : 8
Dimensions of the other rectangle = ?
Let length and width of the other rectangle be x : y
According to the question:


So, the width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.
Answer:
p3+13=37
We move all terms to the left:
p3+13-(37)=0
We add all the numbers together, and all the variables
p^3-24=0
