Joe ordered an 18 inch pizza with pineapple and ham on it from Mr. T's Famous Chicago Style Pizzeria. The pizza was cut into 6 slices. Joe ate only two slices and decided he didn't like the famous pizza and discarded the rest. How many square inches of pizza did he throw away? Use 3.14 for pi. Round to the nearest tenth of a square inch.
Answer:
[tex]A_4 = 170\ in^2[/tex]
Step-by-step explanation:
Given
[tex]Diameter = 18\ in[/tex]
[tex]Slices = 6[/tex]
[tex]Eaten = 2[/tex]
Required
Determine the area of the discarded part
First, calculate the area of the pizza.
[tex]Area = \frac{\pi D^2}{4}[/tex]
Substitute 18 for D and 3.14 for [tex]\pi[/tex]
[tex]Area = \frac{3.14 *18^2}{4}[/tex]
[tex]Area = \frac{1017.36}{4}[/tex]
[tex]Area = 254.34[/tex]
If he eats 2 out of the 6 slices, then it means he discarded 4 out of the 6.
So, the area of the 4 is:
[tex]A_4 =\frac{4}{6} * Area[/tex]
[tex]A_4 =\frac{4}{6} * 254.34[/tex]
[tex]A_4 =\frac{4* 254.34}{6}[/tex]
[tex]A_4 =\frac{1017.36}{6}[/tex]
[tex]A_4 =169.56in^2[/tex]
[tex]A_4 = 170\ in^2[/tex] -- approximated
The area of the discarded is 170 square inches
the product of two consecutive odd number is 143 find the number

Answer:
the answer is 9.4
Step-by-step explanation:
9 4/10= 9+1/10
we know that 4/10 is the same as 4÷10.
therefor:
9 4/10=9+(4÷10)
then using long division for 4 divided by 10 we have:
=9+0.4=9.4
according to the graph, what is the value of the constant in the equation below?
Answer:
20
Step-by-step explanation:

Constant = xy = 4*5 =20
or
constant = xy = 5*4 = 20
or
Constant = xy = 10*2 = 20

Solve the following system using the substitution method.you must show ALL work and use the substitution method.
4x+y=14
x-2y=8
Answer:
y=-2
x=4
Step-by-step explanation:
4x+y=14
x-2y=8 then x=8+2y
substitute for x in 4x+y=14
4(8+2y)+y=14
32+8y+y=14
reduce
32+9y=14
32+9y-32=14=32
9y=-18
9y/9=-18/9
y=-2
x=8+2(-2)=4
Give three ratios equivalent to 9:5
The proportions equal to the ratio 9 : 5 is given by the equation A = 18 : 10 , 27 : 15 and 36 : 20
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the equation will be
A = 9 : 5
Now , the proportion equivalent to the proportion A is given by
A = 9/5 be equation (1)
Multiplying the numerator and denominator by 2 , we get
A = 18/10
So , the value of A = 18 : 10
Now , Multiplying the numerator and denominator by 3 , we get
A = 27/15
So , the value of A = 27 : 15
Now , Multiplying the numerator and denominator by 4 , we get
A = 36/20
So , the value of A = 36 : 20
Hence , the proportion is 9 : 5
