Answer: The unite rate is $3 per pack.
Step-by-step explanation:
The unit rate will the the cost of one pack of donuts.
If 6 packs is equal to $18 dollars, then to find the unit rate we will divide 18 by 6.
18/6 = 3
This means one pack of of donut will cost $3.

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
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%.

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

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 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.

What is the value of x, y, z? Please answer need help soon
Answer:
x = 55
y = 55
z = 70
Step-by-step explanation:
x + 125 is a straight line, 180⁰ x+125=180 x=55⁰
since this is an isosceles triangle, x = z
and the sum of all angles in any triangle is 180⁰
55+55+y=180⁰
y = 70⁰
Answer:
x=55º, y=70º, z=55º
Step-by-step explanation:
We have that xº = 180º - 125º = 55º
As it is an isosceles triangle, we have xº = zº = 55º
Therefore, yº = 180º - (xº + zº) = 180º - (55º + 55º) = 180º - 110º = 70º
Order these expressions from least to greatest.

Answer:
P(marks ≥ 20) = 0.4
Step-by-step explanation:
Marks gotten by the 5 students are;
15, 14, 20, 17, 25
Marks more than or equal to 20 are 2 in number namely 20 and 25.
Thus, probability of getting marks more than or equal to 20 is;
P(marks ≥ 20) = 2/5
P(marks ≥ 20) = 0.4
Elisa withdrew $20 at a time from her bank account and withdrew a total of $140. Francis withdrew $45 at a time from his bank account and withdrew a total of $270. Who made the greater number of withdrawals? Justify your answer.
Answer:
Elisa made the greater number of withdrawals.
Step-by-step explanation:
Given that:
Elisa withdrew $20 at a time and a total amount of $140
Number of withdrawals by Elisa = [tex]\frac{Total\ amount\ withdrawn}{Amount\ withdrawn\ each\ time}[/tex]
Number of withdrawals by Elisa = [tex]\frac{140}{20}=7[/tex]
Francis withdrew $45 at a time and a total amount of $270
Number of withdrawals by Francis = [tex]\frac{270}{45}[/tex]
Number of withdrawals by Francis = 6
On comparing;
7 > 6
Hence,

what equation is equal to the x axis x = 4, x +y = o, x = y, y = 4
The x-axis is equivalent to x = 4, x + y = 0, x = y, and y = 4, and the value of the x-axis is y = 0.
What is equivalent?Expressions that are equivalent do the same thing even when they have distinct appearances.. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s)
The Cartesian plane is what?A coordinate system is a plane with Cartesian coordinates. Each point is uniquely identified by a pair of numerical coordinates that are the signed distances from two fixed perpendicularly oriented lines to the point, measured in the same unit of length.Given that all of the y-values on the x-axis are zero, the x-axis' equation is y = 0.Similar to the x-axis, the y-axis also has all zero values, therefore the equation of the y-axis is x = 0.((This presupposes that we're referring to the Cartesian plane, i.e. we are limiting ourselves to two dimensions.)

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%.
