Answer 1

Answer:

Hmm i don't know is A B C D

CBA should be hmm 90 degrees I think

Then you should be able to calculate

it's so easy

Step-by-step explanation:

Answer 2

Answer:

D. x = 18; ∠DBC = 54

Step-by-step explanation:

m∠ABD + m∠CBD = 90°

2x + 3x = 90°

5x = 90°

x = 18°

m∠DBC = 3x

m∠DBC = 3(18°)

m∠DMC = 54°

Everytime your X goes up by 1, your Y goes up by 4

making the space between 6 and 14 = 10

the exponential factor equation would look something like this

g(x)=3^x

meaning every time x goes up by 1, your exponential factor gets multiplied by 3, making 14y have an exponential factor of 1.

Mk, i don’t know if this is hundred percent correct. Alright so, first add 12 and 16. Those two numbers equal 28. Every triangle equals 180, so if you subtract 28 from 180 that equals 156. The missing X is 156! Sorry if the explanation is kinda bad. My english isn’t very good. Also, if you need your answer to be rounded to the nearest tenth, it will be 160. Hope this helps!

A cylinder has a height of 13 feet and a radius of 11 feet. What is its volume? Use a ~ 3.14
and round your answer to the nearest hundredth.

Answers

Answer:

4939.22 feet cubed.  

Step-by-step explanation:

The formula for the volume of a cylinder is V=3.14*r^2*h

First we square the raidus, which is 11 in this problem.  11 squared is 121.

Next we multiply everything together.

3.14*121 is 379.94.  Then, 379.94 * the height, which is 13, is 4939.22.

Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22
