Answer:
99
Step-by-step explanation:
Since the question is or, we only need to answer one. For q, there is of course no answer that will not end the division in decimals. So lets move on to p. The only number that is greater than 20 is 99. Also, 99 is divisible by 5, it will just end in decimals. So the answer is 99.

A used automobile dealership recently reduced the price of a used compact car by 12%. If the price of the car before discount was $34,500, find the new price.
A. 4,140
B. 36,640
C. 12,000
D. 30,360
Answer:
D
Step-by-step explanation:
The new price of the used compact car is $30,360 if the used automobile dealership recently reduced the price of a used compact car by 12%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
A used automobile dealership recently reduced the price of a used compact car by 12%.
The price of the car before the discount = $34,500
The new price can be found using:
= 12% of $34,500
= (12/100)x34,500
= 0.12x34,500
The reduced amount = $4140
The new price = 34500 - 4140
The new price = $30,360
Thus, the new price of the used compact car is $30,360 if the used automobile dealership recently reduced the price of a used compact car by 12%.

Peter has 5 books with 100 pages and 7 books with 10 pages. How many pages are in peter’s books?
Answer:
Hi, the answer would be that Peter has 570 pages in total.
Step-by-step explanation:
Since he has 5 books with 100 pages, you multiply 5 by 100
5 × 100 = 500
Next, Peter has 7 books with 10 pages each, so you multiply 7 by 10.
7 × 10 = 70
Next, you can add them together to get the total.
500 + 70 = 570
570 is the total.
Hope this helps!
570
Step-by-step explanation:
Because 5 multipled by 100 is 500
Then 7 multipled by 10 is 70
So 500+70=570

Which equation represents a proportional relationship that has a constant of proportionality equal to 0.7?
Answer:
The usual representation of a proportional relationship is ...
y = kx
You want the constant of proportionality (k) to be 7/10, so this is ...
y = (7/10)x
Dividing by x gives the equivalent relationship ...
y/x = 7/10

The length of a rectangle is 3ft longer than its width.
If the perimeter of the rectangle is 50ft, find its length and width.
Answer: the width is 6.25 ft
And the Length is 18.75 ft
Step-by-step explanation:
Length = 3w
Width = w
Perimeter = 3w + 3w + w + w
50 = 3w + 3w + w + w
50 = 8w
w = 6.25
Length = 3w
Length = 3(6.25)
Length = 18.75
Therefore the width is 6.25 ft
And the Length is 18.75 ft

to determine n, the number of cans the grocer will sell during d days the
store is open. Which of these is not a reasonable number of cans of beans
to stock on the shelf for the week? *
Answer:

22 because it is less than 28The phone company NextFell has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 470 minutes, the monthly cost will be $200.5. If the customer uses 590 minutes, the monthly cost will be $242.5.
A) Find an equation in the form
y=mx+b
,
where
x
is the number of monthly minutes used and
y
is the total monthly of the NextFell plan.
The equation in the form y = mx + b is y = 0.35x + 36.
How to represent a linear equation?The equation formed from the expression is a linear equation and should be expressed in the slope intercept form.
y = mx + b
where
m = slopeb = y-interceptTherefore,
y = mx + b
where
x = the number of monthly minutes usedy = the total monthly of the Next fell planusing the coordinates, let's find m
(470, 200.5)(590, 242.5)
Hence,
m = 242.5 - 200.5 / 590 - 470
m = 42 / 120
m = 0.35
Therefore,
y = 0.35x + b
200.5 = 0.35(470) + b
200.5 - 164.5 = b
b = 36
Finally, the equation in the form y = mx + b is y = 0.35x + 36.

Step-by-step explanation:
Last year the total revenue for Clearline phone company was $13.7 million while the revenue for its competitor,the Speakmore was$10.8 million. What is the absolute difference and relative difference?
The absolute difference is estimated as $2.9 million and relative difference is calculated as 26%.
What is defined as the absolute change?The absolute change refers to the actual increase or decrease from the a reference value to a new value:
absolute difference = new value - reference value
In the given question, the reference value is given as $10.8 million.
The new value is $13.7 million.
absolute difference = 13.7 - 10.8
absolute difference = 2.9
Thus, the absolute value if estimated as $2.9 million.
What is defined as the relative difference?The absolute difference is described as a fraction of a reference value by the relative difference:
The formula for calculating the relative difference is;
relative difference = (new value - reference value)/reference value
relative difference = absolute difference/reference value
Substituting the values;
relative difference = 2.9/10.8
relative difference = 0.26
relative difference% = 0.26×100%
relative difference = 26%.
Thus the relative difference is estimated as 26%.

Show that the set of points that are twice as far from the origin as they are from (2, 2, 2) is a sphere. Find the center and radius of this sphere.
Answer:
This is a sphere with a center [tex](\dfrac{8}{3},\dfrac{8}{3},\dfrac{8}{3} )[/tex] and radius [tex]\dfrac{4 \sqrt{3}}{3}[/tex]
Step-by-step explanation:
Given that: (x,y,z)
where;
d₁ is the distance from the origin = [tex]\sqrt{x^2+y^2+z^2}[/tex]
d₂ is the distance from (2,2,2) = [tex]\sqrt{(x-2)^2+(y-2)^2+(z-2)^2}[/tex]
Also;
d₁ = 2d₂
[tex]\sqrt{x^2 + y^2 +z^2 } = 2 \sqrt{(x-2)^2 +(y-z)^2+(z-2)^2}[/tex]
By squaring both sides;
[tex]x^2 + y^2 +z^2 = 2^2((x-2)^2 +(y-z)^2+(z-2)^2)[/tex]
[tex]x^2 + y^2 +z^2 = 4(x-2)^2 +4(y-z)^2+4(z-2)^2[/tex]
[tex]x^2 + y^2 +z^2 =4(x^2 -2x -2x +4) + 4(y^2 -2y -2y +4) + 4(z^2 -2z-2z+4)[/tex]
[tex]x^2 + y^2 +z^2 =4x^2 -16x +16 + 4y^2 -16y +16 + 4z^2 -16z+16[/tex]
Collect the like terms:
[tex]0 = 4x^2 -x^2 -16x +16 + 4y^2 -y^2 -16y +16 +4z^2 -z^2 -16z +16[/tex]
[tex]0 = 3x^2 -16x +16 + 3y^2 -16y +16 +3z^2 -16z +16[/tex]
Divide both sides by 3
[tex]\dfrac{0}{3} = \dfrac{3x^2 -16x +16}{3} + \dfrac{3y^2 -16y +16 }{3} + \dfrac{ +3z^2 -16z +16}{3}[/tex]
[tex]0 = {x^2 - \dfrac{16x}{3} +\dfrac{16}{3} + {y^2 - \dfrac{16y}{3} +\dfrac{16}{3}+{z^2 - \dfrac{16z}{3} +\dfrac{16}{3}[/tex]
Using the completing the square method;
[tex]3(\dfrac{160}{9}) -16 = {x^2 - \dfrac{16x}{3} +\dfrac{160}{9} + {y^2 - \dfrac{16y}{3} +\dfrac{160}{9}+{z^2 - \dfrac{16z}{3} +\dfrac{160}{9}[/tex]
[tex]\dfrac{16}{3}= (x - \dfrac{8}{3})^2+ (y - \dfrac{8}{3})^2+ (z - \dfrac{8}{3})^2[/tex]
∴
This is a sphere with a center [tex](\dfrac{8}{3},\dfrac{8}{3},\dfrac{8}{3} )[/tex] and ;
radius; [tex]\sqrt{\dfrac{16}{3}}[/tex]
[tex]= \dfrac{4 \sqrt{3}}{3}[/tex]
