Answer:
127 square ft

Explanation:
The formula to find the area of a circle with a know circumference is: C^2/4 π.

40^2 is 1600 and 4 times pi is 12.56. Divide 1600 by the 12.56 and you will get your area of 127.39. The answer is 127 square ft after rounding to the nearest square foot.

Answer:

The answer is 64.

Step-by-step explanation:

Lets say the top row is <em>x</em> and the bottom row is <em>y</em>.

Since when <em>x</em> is 13 <em>y</em> is 104 and when <em>x</em> is 14 <em>y</em> is 112 that means the <em>y </em>value goes up by 8 every time.

when x=3: 16+8=24

when x=4: 24+8=32

when x=5: 32+8=40

when x=6: 40+8=48

when x=7: 48+8=56

when x=8: 56+8=64

Hope this helps you!!!!

It's 42, here's a quick trick to do this, so we know there's 7 movies, and to find the combination we know we can't choose 2 of the same movie, so to make this part easier , in your head take one movie from the stack out of the stack now there's 6 movies. It's now just the "plug and play" step , (7)*(6)=(42)
I'm sorry If this is to long of an explanation, but I hope that this helps you understand on how to do this problem. Have a nice day :)

Step-by-step explanation:

Given data

rate= 5%

time= 3years

A=$4630.50

P=?

we know that

A=P(1+rt)

$4630.50=P(1+0.05*3)

$4630.50=P(1+0.15)

$4630.50=P(1.15)

P=4630.50/1.15

P=$4026.52

The intitial amount is $4026.52

The value of x from the given equation is -4/3

<h3>Factorization</h3>

Given the quadratic equation x^2 – 3x – 4 =  x^2 – 6x + 8

  • Collect the like terms

x^2 – 3x – 4 - x^2 + 6x - 8 = 0

-3x + 6x - 4 + 8 = 0

3x + 4  = 0

  • Subtrcat 4 from both sides

3x + 4 - 4  = 0 - 4

3x = -4

  • Divide both sodes by 3

3x/3 = -4/3

x = -4/3

Hence the value of x from the given equation is -4/3
