the total cost of renting a cotton candy machine for 4 hours is $72. what equation can be used to model the total cost y for renting the cotton candy machine x hours
An equation which can be used to model the total cost (y) for renting the cotton candy machine (x) hours is y = 18x.
What is an equation?An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
What is a system of equations?A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneously.
In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:
Let x represent the number of hours.Let y represent the total cost.Translating the word problem into an equation, we have;
y = 72/4 × x
y = 18x

Answer:
i) (121)^1/2 = 11;
11*11 = 121
ii) (12321)^1/2 = 111;
111*111 = 12321
iii) (1234321)^1/2 = 1111;
1111*1111 = 1234321
iiii) (123454321)^1/2 = 11111;
11111*11111 = 123454321

A high school is having a pancake breakfast fundraiser.They have 5 packages of pancake mix that each feed 140 people.The function N(p)=140p represents the number of people,N(P),that packages of pancake mix feed write the domain and range as compound inequalities.
Answer:
They have 5 packages of pancake mix.
N(p) = 140*p
Represents the number of people that can be feed with p = # of packages of pancake mix used.
Now, the domain will be the set of the possible values of p that we can use here.
the set of possible values of p will be:
{0, 1, 2, 3, 4, 5}
We can not use more than 5 because there are only 5 packages.
But we can use actually half a package or a third, so we not should use only whole numbers in the domain, then the domain can be written as:
D = 0 ≤ p ≤ 5
Now, the range is the set of the possible values of N(p)
The minimum will be when p = 0.
N(0) = 140*0 = 0
The maximum will be when p = 5
N(5) = 140*5 = 700
Then the range can be written as:
R = 0 ≤ N ≤ 700
Here we could add another restriction, because we can only feed a whole number of people, then we also should add the restriction that N must be a whole number:
R = 0 ≤ N ≤ 700, N ∈ Z

What is an equation of the line that passes through the point ( 8 , − 4 ) and is parallel to the line x − 4 y = 12 x−4y=12?
Answer:
as the line is parallel we do not change x-4y what we change is the result x = 8 & y = -4 so the result is 8 - 4 (-4) = 24 so the equation is 24

Answer:
see below
Step-by-step explanation:
y + 2/5y= y (1 + 2/5)
= 7/5 y
y - 0.32 y (just add)= 1y - 0.32y
= 0.68 y
y - 2/5y
= y (1 - 2/5)
= 3/5 y
y + 0.32 y (just add)
= 1y + 0.32y
= 1.32 y
Answer:
Step-by-step explanation:
y + 2/5y
= y (1 + 2/5)
= 7/5 y
y - 0.32 y (just add)
= 1y - 0.32y
= 0.68 y
y - 2/5y
= y (1 - 2/5)
= 3/5 y
y + 0.32 y (just add)
= 1y + 0.32y
= 1.32 y

Jason has $90 to spend. He wants to purchase a bag for $35,one eraser for $10, and three pencils. Each of the pencils costs the same price. This will use up all of Jason's money. Determine the price of a pencil.
Answer:
1 pencil = $15
Step-by-step explanation:
Starting money = 90
Bag price = 35
Eraser price = 10
Price per 1 pencil = X
90 - 35 = 55
$55 after buying the bag.
55 - 10 = 45
$45 after buying the eraser.
45 ÷ 3 = 15
$15 dollars for each pencil.
