Answer: Part A: Noah eats 10/8's. Or 1 and 2/8's if you have to simplify.
Part B: Draw the circles and cut them into 8 slices and color in two of each.
Part C: So if Jessica ate half of what Noah eats, she only ate 5/8's of pizza.
Part D: Noah and Jessica together ate 15/8's of pizza or if you want to simplify, 1 and 7/8's of pizza. There is 25/8's of pizza left, or 25 pieces left. And the remaining friends ate 1/5 of the remaining pizza which was 25 pieces. So, they ate 5 pieces. So they ate 5/8's of the remaining pizza.

The Cooking Club made some pies to sell at a basketball game to raise money for the new math books. The cafeteria contributed four pies to the sale. Each pie was then cut into five pieces and sold. There was a total of 60 pieces to sell How many pies did the club make?
Answer:
the cooking club made 8 pies
Step-by-step explanation:
first do 60 divided by 5 to find the total number of pies you get 12
then since the cafetria donates four pies and the cooking club makes the rest, you do 12-4=8
There were 11 pies cooked in all by the club to earn money for the basketball game.
What is Function?
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
Given, The Cooking Club made some pies to sell at a basketball game to raise money for the new math books. The cafeteria contributed four pies to the sale.
Each Pie cut into four pieces
Since there were 60 pieces of pie
The total number of pies sell at a basketball game = 60/4
The total number of pies sell at a basketball game = 15
Also, given there were four pies donated by Cafeteria
Thus,
Total pie basketball team made = 15 - 4
Total pie basketball team made = 11
Therefore, the Total number of pies made by the club to raise funds for the basketball game is 11.

the square with a side length (x + 3) and an equilateral triangle with side lengths (3x-1) have the same perimeter what is the value of x?
Help please
Answer: x = 9/5 or [tex]1\frac{4}{5}[/tex]
35 1/5 is the perimeter of the square and the triangle.
Step-by-step explanation:
The square has 4 sides, so the perimeter of the square is 4(x+3)
The triangle has 3 sides so the perimeter is 3(3x-1)
The perimeters are equal, so 4(x+3) = 3(3x-1)
Solve by distributing and then
4x +12 = 9x - 3 subtract 4x from both sides and add 3 to both sides
4x-4x +12 -3 = 9x-4x -3 +3 cancel the zero sums and combine similar terms.
9 = 5x divide both sides by 5
x = 9/5
Check: 4(9/5 +3) = 3[3(9/5) -1]
36/5 + 3 = [3( 27/5 -1 ] 27/5 -3 -3 equivalent -15/5 27/5 -15/5 = 12/5
36/5 = 3(12/5) = 36/5 TRUE! simplify to mixed numbers
35 1/5 is the perimeter of the square and the triangle.

Which polynomial is in standard form?
2x-3x+ 10x
-16x2-9x+12
15x-6x2+3
-7x?+ 9x9 - 11x
Answer:
[tex]-16x^2-9x+12[/tex]
Step-by-step explanation:
[tex]2x-3x+ 10x[/tex]
[tex]-16x^2-9x+12[/tex]
[tex]15x-6x^2+3[/tex]
[tex]-7x+ 9x^9 - 11x[/tex]
Standard form is when the polynomial's terms's degrees go down so the highest power is the first and the lowest is the last.
We see that the first expression can be more simplified so that isn't right.
We see that the second expression is in standard form so that might be right.
We see that the third expression has the highest power as the second term so that is wrong
We see that last expression is the same as the third one so that is also wrong.
We can conclude that [tex]-16x^2-9x+12[/tex] is the correct one or in standard form.
A farmer wants to set up a pigpen using 40ft of fence to enclose a rectangular area of 51 square feet. Find the dimensions of the pigpen.
Answer:
The sides of the pigpen are 3 by 17
Step-by-step explanation:
Perimeter of pigpen => 2x + 2y = 40
Area of pigpen => xy = 51 (this is assuming x = length, and y = width)
Let's isolate "y" for the first equation;
2x + 2y = 40
2(x + y) = 40
x + y = 20
y = 20 - x
xy = x(20 - x) = 51 = 51
20x - x^2 = 51
x^2 - 20x + 51 = 0
According to the quadratic equation =>
x = ( - (- 20) + √(- 20)^2 - 4 * 1 * 50 ) / 2 * 1 = 17
x = ( - (- 20) - √(- 20)^2 - 4 * 1 * 50 ) / 2 * 1 = 3
The dimensions of the pigpen are actually 17 by 3
Proof: 17(3)= 51, 2(17) + 2(3) = 40
b. The 100th term of 60, 110, 160, ... is (Simplify your answer.) How to do this?
The 1st term is 60.
Add 50 to this to get the 2nd term, 60 + 50 = 110.
Add 50 to that to get the 3rd term, 110 + 50 = 160.
Add 50 to that to get the 4th term, 160 + 50 = 210.
And so on...
Notice that in the 2nd term, we added 1 copy of 50 to the 1st term.
In the 3rd, we ultimately added 2 copies of 50 to the 1st term.
In the 4th, we added 3 50s.
And so on... If the pattern continues, then the n-th term can be obtained by adding (n - 1) copies of 50 to the first term.
So, the 100th term is
60 + (100 - 1) * 50 = 5010

Answer:
25 baggies; each bag has 2 blueberry scones, and three cranberry scones.
Step-by-step explanation:
The question format is a bit bugged, but I assume the question is asking "You have 50 blueberry scones and 75 cranberry scones. You want to make as many identical bags as possible. What is he greatest number of bags you can fill?"
The first thing to realize when solving this question is that whatever the answer is equal to, it must be able to be equally divided from both 50 and 75, otherwise it will have a remainder, and at least one bag will have too many or not enough scones.
This means that the answer must be a factor of both 50 and 75.
The factors of 50 includes {1, 2, 5, 10, 25, 50}
The factors of 75 includes {1, 3, 5, 15, 25, 75}
In the two sets, only 1, 5, and 25 are common factors. Of the three factors, 25 is the greatest number, and thus the greatest number of bags that can you can fill.

Round your answer to 3 decimal places. (d) Which of the following are potential major sources of variability in the experiment
Answer:
(a)7.185
(b)0.000371
(c) 0.019
(d)Sample variance and Sample standard deviation
Step-by-step explanation:
We are given the following sample data.
7.15, 7.20, 7.18, 7.19, 7.21, 7.20, 7.17, 7.18.
(a) Calculate the sample mean. Round your answer to 3 decimal places.
The formula for sample mean =
Sum of terms/Number of terms
= 7.15 + 7.20+ 7.18+7.19+7.21+7.20+7.17+ 7.18/8
= 57.48/8
= 7.185
(b) Calculate the sample variance. Round your answer to 6 decimal places.
The formula for sample Variance =
(x - mean)²/n - 1
n = 8
Sample variance = (7.15 - 7.185)² + (7.20-
7.185)²+ (7.18 -7.185)² + (7.19 -7.185)² + (7.21 - 7.185)² + (7.20 - 7.185)² + (7.17 - 7.185)² + (7.18 - 7.185)² /8 - 1

= 0.0026/7
= 0.000371428571
Approximately to 6 decimal places = 0.000371
(c) Calculate the sample standard deviation. Round your answer to 3 decimal places.
The formula for Sample Standard Deviation = √Sample variance
= √0.000371428571
= 0.01927248223
To 3 decimal places = 0.019
(d) Which of the following are potential major sources of variability in the experiment

The function T(d)=10d + 20 gives the temperature in deegrees celcius inside the earth as a function if d, the depth in kilometers ,Find the temperature at.
Answer:
Step-by-step explanation:
The question is incomoplete. Here is the complete question.
The function T(d)=10d + 20 gives the temperature in deegrees celcius inside the earth as a function if d, the depth in kilometers ,Find the temperature at 5km, 20km and 100km
T(d)=10d + 20
T(5)=10(5) + 20
T(5)= 50+ 20
T(5) = 70
Hence the temperature is 70 when d = 5km
when d = 20km
T(20)=10(20) + 20
T(20)= 200+ 20
T(20) = 220
Hence the temperature is 220 when d = 20km
when T = 100km
T(100)=10(100) + 20
T(100)= 1000+ 20
T(100) = 1020
Hence the temperature is 1020 when d = 100km
The temperatures at 5km, 20km and 100km are; 70°C, 220°C, and 1020°C respectively.
The complete question requires that we find the temperature at 5km, 20km and 100km.
The temperature function is; T(d)=10d + 20
For 5km;
T(5)=10(5) + 20T(5) = 70°CFor 20km;
T(20) = 10(20) + 20T(20) = 220°CFor 100km;
T(100)=10(100) + 20T(100) = 1020°CRead more;

If f(x)=×^2+7x-5 and you divide by x-2, What is the quotient and remainder?
Answer:
The quotient is : x+9
The remainder is : 13
Step-by-step explanation:
The question requires you to perform the long division method;
This will be;
[tex]x-2\sqrt{x^2+7x-5}[/tex]
start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;
x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x
- x²-2x+0 ------------perform subtraction of like terms
---------------------
9x-5 ----now divide this answer by x-2 ,starting with x and 9x
----------------------This will give , 9 then multiply 9 by x-2 to get 9x-18 and perform the subtraction operation as;
9x-5
- 9x-18
