Y=2x+1 I think this is correct but I don’t know how to do equations very well
Answer:
Volume = 2520 cm^3.
Step-by-step explanation:
The volume of a pyramid = 1/3 * area of the base * height.
The base of this pyramid is a triangle and its area
= 1/2 * 18 * 24 cm^2 so the volume of the pyramid is:
1/3 * 1/2 * 18 * 24 * 35
= 2520 cm^3.
Answer:
$2.35 for one video
Step-by-step explanation:
You set up two equations:
$7.50= p + 2v
$12.20= p + 4v
You then set both equal to p
p=-4v+12.20 and p=-2v+7.50
So you can set them equal to each other and solve for v (the cost of one video)
v= $2.35
Selection A is appropriate.
_____
20*1.1^n is the general expression for the cost n years in the future.
20*1.1^3 = 26.62 is the cost 3 years in the future.
