The cylinder:
pi x r^2 x h
= pi x 8^2 x 20
then times it by a half
= 2009.6
The prism:

= 32 x 20
= 640
All up:
2009.6 +640

What value of x would make lines land m parallel?

solniwko [45]

Answer:

$x = 75$

Step-by-step explanation:

Given

See attachment

Required

The value of x that makes l and m parallel

Let the angles be ABC (See attachment 2)

$\angle CAB$ is corresponding to 50 degrees. So:

$\angle CAB=50$

$\angle ABC$ is corresponding to 55 degrees. So:

$\angle ABC = 55$

This means that:

$\angle ABC + \angle CAB + x = 180$

$50 +55 + x = 180$

Solve for x

$x = 180 - 50 - 55$

$x = 75$

WILL GIVE BRAINLIEST

Answer:

It has no solution because, 14x cancels out -14x when you move the variables to the left and leaves the equation as 0 = -12, however we know that 0 does not equal -12 which means this solution is false; therefore this equation has no solution since 0 does not equal -12.

Step-by-step explanation:

5 - 4x - 7 - 10x = -8x - 4 - 6x - 10 (Given)

-2 - 14x = -14x - 14 (Combine like terms)

0 = -12 (Move variables(x) to the left and the constants to the right)

Torri had $20 to buy a birthday present for her dad.She decided to buy a DVD for $18.The sales tax is 7%.Does she have enough mo

Brut [27]

Yes, Torri does have enough.
How to find the answer:
Find the decimal of 7% which is 0.07
Multiply 0.07 times $18 which gives you 1.26
0.07 x 18 = 1.26
Add 1.26 to 18 which gives us 19.26
1.26 + 18 = 19.26
Our finale answer is 19.26
Torri has enough money to buy her dad the DVD.
Hope this helps! =)
