A 12-inch diameter pizza is sliced into sixths. What's the area of one slice?

Answers

Answer 1
Answer: find area then divide by 6
area=pir^2

d=2r
d/2=r
d=12
12/2=6=r

area=pi6^2
area=36pi
divide by 6 to find sixths
36pi/6=6pi

area=6pi in^2
if aprox pi=3.14 then
area=18.84 in^2

Does (-15, -691) make the equation y = -51x - 74 true?


Answers

Well, we can input both variables to check and see if the numbers hold.

-691 = -51(-15) - 74

-691 = 765-64

-691 = 701

(-15, -691) does not make the equation true.

Answer:

701 ≠ -691

A hovercraft takes off from a platform. It’s height (in meters), x seconds is modeled by h(x)=-(x-11)(x+3). What is the height of the hovercraft at the time of the takeoff?

Answers

Answer:

The height of the hovercraft at the time of takeoff is  33  meters.

Step-by-step explanation:

Height of hovercraft  x  seconds after takeoff  =  h(x)  =  -(x - 11)(x + 3)

Height after takeoff is  =  h(0)  =  -(0 - 11)(0 + 3)  =  -(-11)(3)  =  33

So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.

Answer: 33  meters.

The GCF of any two even numbers is always even. Determine whether the statement is true or false. If true, explain why. If false, give a reason.

Answers

The question is asking us whether it is true that The GCF of any two even numbers is always even. GDF means the greatest common factor, for example the GCF of 24 and 32 is 8 - it's the biggest of their factors. The GCF is a multiple of all the (prime) common factors, and 2 is a common factor of two even numbers, so GCF will always be even - this is true!
It is true that the GCF of any two even numbers is always even. GCF refers to the greatest common factor that two or more numbers have, and obviously it is going to be an even number. Take 18, 30, and 42 as your example - their GCF will be 6, which is an even number, as are those three numbers. GCF of odd numbers will be odd, and GCF of an odd and even number is also always even.

Jared is putting a new deck off the kitchen. The deck will be 94.45 inches deep. He will use 16 boards that are each 5.7 inches wide. He has to leave a small space between the boards. If the 15 spaces between the boards are all equal, how wide will they be?

Answers

16 boards that are 5.7 inches wide each make a total of 91.20 inches.
 
    16
x 5.7
  112
+800
 91.2 inches

Since the deck itself is 94.45 inches deep, we can subtract 91.2 from the number:

  94.45
-91.20 
   3.25 inches.

Finally, we divide 3.25 by 15, since that's the amount of spaces we want and they have to be equal:

3.25/15= .21667

We'll round that to two numbers, so we'll end up with .22.

Your final answer is .22 inches wide for each space.

Answers

First, I will list the factors of 80
80:
1, 2, 4, 5, 8,10,16, 20, 40, 80

Now the factors of 116:
1, 2, 4,19,58, 116

Therefore, your answer is 4. Since their highest common factor is 4
You are correct #8 is the highest number.
