mario has 4 large veggie pizzas. each of his friends will eat 2/6 of one pizza, if mario wants to figure out how many friends he can feed, which statements are true? select all that apply (keyword all that apply) A) divide 4 whole pizzas into groups of 2/6 B) divide 2/6 of a pizza into 4 groups C) each pizza must be divided into 4 parts D) each pizza must be divided into 6 parts E) mario can feed 12 friends with 4 pizzas F) mario can feed 24 friends with 4 pizzas (make sure to look at image thank you)
Answer: Mario can (E) feed 12 friends with four pizzas.
Step-by-step explanation:
There are 4 pizzas, you'll need to find out how many 2/6 can fit into four pizzas which one of them equals 6/6. You know that 2/6 pizzas for each friend, so you can count how many slices of pizzas are there by two.

The area of a sector of a circle is 2π in2.
Its central angle is 45�. Which is the radius of the circle?
a. 16 in. c. 1/16 in.
b. 4 in. d. 1/4 in.
Answer:
B: 4 in.
Step-by-step explanation:
As an area 2π with 2 in. means that it has a 45 degree central angle which means that it is 4.
A rectangle has a length of 8 and width of 12. A scale copy was made with a width of 24. What is the area of the new rectangle?
Answer:
192 feet^2
Step-by-step explanation:
Length X Width = area
Answer:
The area of the new rectangle is 384 square units.
Step-by-step explanation:
For the original rectangle, the length is 8, and the width is 12. For the scale copy, the width is 24 (12 × 2), so the length will be 16 (8 × 2). Multiplying 24 by 16, we obtain 384 as the area of the new rectangle.
What would be the equation (using x) to solve "What are the dimensions of a rectangle whose length is 4 more than twice the width and whose perimeter is 3 less than 7 times the width?"
Let w = the width
Let 2w + 4 = the length
Let 7w-3 = the perimeter
P = 2l + 2w
7w-3 = 2w + 2(2w+4)
7w-3 = 2w + 4w + 8
w = 11
length = 2w + 4 = 2(11) + 4
length = 26
P = 7(11) -3 = 77 - 3
Perimeter = 74
Answer:Let w = the width
Let 2w + 4 = the length
Let 7w-3 = the perimeter
P = 2l + 2w
7w-3 = 2w + 2(2w+4)
7w-3 = 2w + 4w + 8
w = 11
length = 2w + 4 = 2(11) + 4
length = 26
P = 7(11) -3 = 77 - 3
Perimeter = 74

The work that Ryan did to find the greatest common factor of 48 and 72 is shown below.
Prime factorization of 48: 2x2x2x2x3
Prime factorization of 72: 2x2x2x3x3
The greatest common factor is 2'2'2'3x3
What is Ryan's error?
(A) Ryan did not add the common prime factors to get the greatest common factor
(B) Ryan did not list all the factors in the prime factorization of 48
(C) Ryan did not list all the factors in the prime factorization of 72
(D) Ryan did not include only common prime factors in the greatest common factor
Answer:
The work that Ryan did to find the greatest common factor of 48 and 72 has no error, and Ryan found the least common multiple.
What is GCF (the greatest common factor)?
GCF or greatest common factor is the common number that all the term has in a group of terms.
The work that Ryan did to find the greatest common factor of 48 and 72 is shown below.
Prime factorization of 48: 2,2,2,2,3
Prime factorization of 72: 2,2,2,3,3
The greatest common factor is 2 ' 2 ' 2 ' 2 ' 3 ' 3
Here, the greatest common factor found is 2 ' 2 ' 2 ' 2 ' 3 ' 3 which is,
The number 144 is divisible by 48 and 72 in 3 times and 2 times respectively.
Thus, the work that Ryan did to find the greatest common factor of 48 and 72 has no error, and Ryan found the least common multiple.

Answer:
[tex]\displaystyle {y^4}[/tex]
Step-by-step explanation:
The GCF of a set of numbers is the biggest divider that will divide all the numbers without leaving a remainder
As an example, the GCF of 4, 8 and 20 is 4, for 3, 4 and 5 it is 1 since there is no common factor
[tex]\textrm {We have the three numbers as }[/tex] [tex]y^4, y^5 \;and\; y^{10}[/tex]
Which of these numbers will divide into each of these without leaving a remainder?
[tex]\mathrm{The \:exponent\:rule}:\quad \dfrac{x^a}{x^b}=x^{a-b}[/tex]
This means the smallest exponent value [tex]y^4[/tex] will be the GCF because
[tex]\dfrac{y^4}{y^4} = 1\\\\\dfrac{y^5}{y^4} = y^{5-4}} = y^1\\\\\dfrac{y^10}{y^4} = y^{10-4}} = y^6\\\\\\[/tex]
So the general rule for finding the GCF of [tex]y^a, y^b \;and\; y^c is\\\\\mathrm {\;Choose\; the\; one \;with \;the \;lowest \;exponent \;value \;among \;exponents\; a, \;b \;and\; c}[/tex]

What is the length of bottom side of the scaled copy?
Answer:
n each scaled copy, the sides are a certain number of times as long as the corresponding sides in the original. We call this number the scale factor. The size of the scale factor affects the size of the copy. A scale factor greater than 1 makes a copy that is larger than the original.

4^5-2
64
2. 8^-2
apply exponent rule a^-b =1/a^b

8208
Answer:
1. 64
2. 1/64
3. 8208
Step-by-step explanation:
1.
4^5 = 1024
4^2 = 16
1024/16 = 64
2.
8^-2 = 8^(-1)x2
1/8^2 = 1/64
3.
19(2)x (2(3))^3(3)^0
38x6^3x1
38x216x1

To find the total cost we need to know whats fixed, and what's variable (changing)
Fixed: $14 handbag
Variable: $0.50 / earring
Set up your polynomial, rule of thumb, all variables get multiplied by x
Total cost = x($0.50/earring) + $14 handbag
Substitute 0,5,10, and 15 for x and see which one matches the answer choices

Find the slope of the line that has a y intercept of 4 and passes through the point (-3, 1)
Answer: m = 1 (m is slope)
Step-by-step explanation:
1. y-int is coordinate, so it is (0,4)
2. with (0,4), we can now use (-3,1):
4 - 1 = 3 and with the x, it is 0 + 3 = 3
So, it is 3/3 = 1, so the slope is 1
Answer:
Line L1 : Passes thro' (3,3)
y-intercept = 4 ===> (0,4)
Slope = (4 - 3)/(0 - 3) = 1/-3
Slope of L1 = -1/3.
