The base of a right prism is a right triangle. The lengths of the legs of the right triangle are 4 centimeters and 8 centimeters. The height of the prism is 5 centimeters. What is the volume of the prism? A. 80 cm B. 160 cm C. 240 cm D. 320 cm

Volume of a prism = Area of the Cross-Section x Length

Answer is A!

Step-by-step explanation: I know im very late, but to people who need the answer to this question it is A.) 80.

Here's how you get to 80 for the total volume.

First you take 4x8 that equals 32. Then do 32x0.5 or 1/2 and that gives you 16! Then finally you take your last digit 5 and multiply 16 by 5. That gives you 80. Here's the formula on how to find the volume for a right triangle: b x l x 0.5 x h! B stands for base, L stands for length, and H stands for height! I'm very glad I could assist you!

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
