Help for brainiest

Mathematics
1 answer:
Andru [333]3 years ago
7 0

Answer:

Option D

Step-by-step explanation:

Formula to use: V=\frac{1}{2}(b*a)*h\\

b=base of triangle   a=altitude of triangle  h=height of prism

Doing \frac{1}{2}(b*a) is essentially finding the area of the triangle and after multiplying by h will give you the volume of the triangular prism.

Solve: V = \frac{1}{2}(3*3)*7  or option D

Ps. Altitude is perpendicular or 90 degrees to the side I used for the base, so it wouldn't be option C.

By what percent is the change in price if: <br> the price was $250 and now is $100
drek231 [11]

Answer: 60 percent decrease

===========================================

Change in price = new - old = 100 - 250 = -150

The negative change means the price has gone down

Divide this change in price over the original 250 and convert to percent form

(change in price)/(original price) = -150/250 = -0.60

which converts to -60%

The negative percent change in price indicates a price decrease

So the price goes down by 60% meaning that it lost 60% of its value

Note how 60% of 250 is 0.60*250 = 150 which was the change in price computed earlier.
