T=2π√l/g
T/2π=√l/g
(T/2π)²=l/g
g=l/(T/2π)²
g=l/T²/4π²
g=4π²l/T²

T=2π√8/2
T=2π*2
T=4π

Stephen makes wooden shelves for his room he starts with a board that is 20 feet long.Stephen wants to make the shelves 3/4 foot
jek_recluse [69]

The number of shelves stephen can make is approximately 27

<h3><u>Solution:</u></h3>

Given that Stephen makes wooden shelves for his room

Stephen wants to make the shelves 3/4 foot long

He starts with a board that is 20 feet long

To find: number of shelves he can make

So the number of shelves stephen can make can make is found out by dividing 20 feet long board by 3/4 foot long

\text {number of shelves }=\frac{\text { total length of board stephen has }}{\text { length of each board }}

\text {number of shelves }=\frac{20}{3 / 4}=\frac{20}{0.75}=26.6

So the number of shelves stephen can make is approximately 27

The area of a parallelogram is 6 ft' and the height is 3 ft. Find the length of the corresponding base.
Reil [10]
Just do 6/3 because you have the area and one length, just divide the area by the height you have.

How do I do GCF (greatest common factor on -5y - 35? I need help because I am not good at it.
ICE Princess25 [194]

Answer:

-5(y+7)

Step-by-step explanation:

Well, the numbers you can divide 5 with are 1 and 5.

35 divides both with 1 and 5 too, but since 5 is the greatest, you choose 5.

so,

you divide both with -5, since both are negative.

-5y/-5 = y

-35/-5 = 7

so,

-5(y+7)

check:

-5*y = -5y

-5*7 = -35

so,

-5y-35, that's true.

Solve.<br> y = 2x - 5<br> y = -2x - 9
guajiro [1.7K]

Answer:

(-1,-7)

Step-by-step explanation:

Substitute 2x-5 (from the first equation) as the y-value for the second equation, so you have something that looks like this:

2x-5 = -2x-9

Add 2x to both sides: 4x-5 = -9

Add 5 to both sides 4x = -4

Divide both sides by 4: x = -1

Substitute -1 for x in either equation (you'll get the same y-value)

I need help thank you
erma4kov [3.2K]

Answer:

≈ 5

Step-by-step explanation:

<u><em>You can use the Pythagorean Theorem to solve this:</em></u>

a^{2} + b^{2} = c^{2}

<u><em>Now plug in the numbers into the formula:</em></u>

6^{2} + b^{2} = 8^{2}

36 + b^{2} = 64

<u><em>Subtract 36 from both sides:</em></u>

36 + b^{2} = 64

-36        -36

_________

b^{2} = 28

<em><u>Square both sides:</u></em>

\sqrt{b^2} = \sqrt{28}

b = 5.29

b ≈ 5
