Answer:

they each get 8/10 of the pizza, equal to 4/5 simplified

The fraction of pizza each friend gets is A = 4/5 of the pizza

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction of pizza each friend gets is A

Now , the total number of friends = 5

The number of pizzas = 4

So , the fraction is A = 4/5

Hence , each friend gets 4/5 of the pizzas

Answer:

area: 31.63ft perimeter: 21.71ft

Step-by-step explanation:

Divide this up into 2 right triangles and 2 semicircles

Area:

right triangles: 2(0.5(3)(4))= 12ft

semicircles: 2(0.5*π*2.5²)= 19.63ft

area of entire buttcheek: 12+19.63=31.63ft

Perimeter:

top: 6ft

arcs: 2(π*2.5)= 15.71ft

perimeter of entire buttcheek: 6+15.71=21.71ft

Sophia's polygon is, ''5 - sided polygon'' or ''Pentagon.''

Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The minimum number of triangles needed to construct the polygon Sophia made is 3.

And, To find Sophia's polygon.

Now, We know that;

The Shape of Pentagon is made with 3 triangles.

Hence, Sophia's polygon is known as,

⇒ 5 - sided polygon or Pentagon.

Therefore, We get;

⇒ The polygon make by Sophia's is, Pentagon.

Step-by-step explanation:

36 = 12x

x=3

Answers:

21.75

1.37

10

15

Step-by-step:

Dozen flyers:price

4:7.25

12:x

To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75

Question 2:

We can write teh following equation

.49+.22(x-1)=price

This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that

We can plug in an x value to get

.49+.22(5-1)

.49+.22(4)

.49+.88

1.37

Question 3:

We can write the following equation

x+2=y

We need to find out what happens when x=8

8+2=10

Question 4:

We can solve this with ratios

x:y

1.5:4.5

5:x

To solve just multiply 4.5 by 10/3 and get 15

We can just multiply

Answer:

1. 7.25/4=1.8125 so 1.8125x12=21.75

2. 0.49+(0.22x4)=1.37

3. rule is x+2=y so x=8 then y=10

4.rule is 3(x)=y so x=5 then y=15

Step-by-step explanation:

if im wrong im sorry

Step-by-step explanation:

firstly draw the triangle and label it. (you will find the picture down)

Now this remind us with the cosine rule. (you will find the picture down)

This rule says that the square of the given length of the side of a triangle is equal to the sum of the squares of the length of other sides minus twice their product and multiplied by the cosine of their included angle.

So using that rule we can say that:

[tex]QS^{2}[/tex] = [tex]QR^{2} +SR^{2} - 2(QR)(SR)(cosR)[/tex]

square root both sides, so you will have QS alone in one side.

QS = [tex]\sqrt{ [QR^{2} +SR^{2} - 2(QR)(SR)(cosR)]}[/tex]

plug in the values we have and y=this will yield:

QS = [tex]\sqrt{ [11^{2} +16^{2} - 2(11)(16)(cos38)] }[/tex] = 9.98099267 = 10
