What do you know to be true about the values of p and q?
Harrizon [31]

The thing that's true about the values p and q is that p = q.

The total <em>sum of the angles</em> in a triangle is 180°.

From the first triangle, the value of p will be:

80° + 20° + p = 180°

100° + p = 180°

p = 180° - 100°

p = 80°

From the second triangle, the value of q will be:

55° + 45° + q = 180°

100° + q = 180°

q = 180° - 100°

q = 80°

Therefore, p = q.

FIND THE EXACT VOLUME PLEASE HELP ILL GIVE BRAINLIESTTTT
Eva8 [605]

Answer:

495 in

Step-by-step explanation:

The formula for the volume of a triangular prism is V = \frac{1}{2} · w · h · l, where w represents with, l represents length, and h represents height. Using this and plugging in the values, we can solve.

V = \frac{1}{2} · 5 · 11 · 18

V = 2.5 · 11 · 18

V = 27.5 · 18

V = 495

hope this helps :)

The base of a cylinder has an area of 64π in2. If the height of the cylinder is 10 in., what is the total volume?
Stells [14]

Answer:

see explanation

Step-by-step explanation:

The volume (V) of a cylinder is

V = area of base × height

here area of base = 64π and height = 10, hence

V = 64π × 10 = 640π in³ ← exact value

What is the solution to 11 = x – 4?
marishachu [46]
Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4

+4 onto the 11 and + 4 on to the -4 which means you just have 15=X
