Answer:

This is pythagoras

A squared plus b squared equals c squared.

The unknown side is c as its the hypotenuse,

So the length of the first side is 6.4 this squared = 40.96

The other length is 12 as 6 is the radius so the diameter of the circle amd therfore the length of the triangle is 12.

12 squared is 144

144 + 40.96 = 184.96

The length of c squared is 184.96

To find the length of c alone we calculate the square root.

The square root of 184.96 = 13.6

? = 13.6

Can someone please help me

pentagon [3]

V = Volume of cylinder
B = area of base
h = height of cylinder

It turns out that
V = B*h
In a similar way to that of a cube

If we know that V = 84pi and h = 7, then we can plug those values into the formula above, and solve for B

V = B*h
84pi = B*7
84pi/7 = B*7/7 ... divide both sides by 7
12pi = B
B = 12pi

Therefore the base is 12pi square units

Can some explain this

DaniilM [7]

Answer:

rectangle: 2x+2 wide by 2x high

triangle: 2 high

Step-by-step explanation:

Usually, a problem like this is asking you to find dimension expressions that combine to give you the given expression. There are usually a number of possibilities. Using the designators in the attached, we would generally like to have B > C and A about the same as C. That doesn't seem possible with the given factors.

The given quadratic expression factors as ...

area = 4x^2 +6x +2 = (2x+2)(2x +1)

This might be written to match the area formula as ...

(2x +2)(2x +2/2)

This would give A=2, B=2x+2, C=2x, as shown in the attachment.

Sarah has to pay a one-time $300 deposit for her apartment. Each month she pays $700 for rent. How much would Sarah pay for “n”

Alex73 [517]

Answer:

700n + 300

Step-by-step explanation:

We know that no matter what happens, Sarah has to pay a One-Time $300 for her deposit.

Now, we know that for every month she stays in the apartment, it will cost her $700.

So, we can come up with a formula to find out how much she would pay:

700n + 300

Hope this helps!
