Carlos saves aluminum cans to sell to the recycling center. He recently recycled 43 pounds of cans and received $23.65. How many dollars would he get at this rate for recycling 200 pounds of cans?
Answer:
$354
Step-by-step explanation:
first we need to find out how much 1 lb of can is then we can multiply that by 200 to get the answer.
so I divided 43 by 23.65 and got 1.81818181
i'll round that to $1.82 so that equals 1 lb of a can
multiply that by 200
the answer is $354
For recycling 200 pounds of cans, he will get $110.
What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Carlos saves aluminum cans to sell to the recycling center. He recently recycled 43 pounds of cans and received $23.65.
For 43 pounds, he recieved $23.65
For 1 pound, he will receive $(23.65/43)
For 200 pounds, she will receive $(23.65/43) x 200 or $110.
Therefore, for recycling 200 pounds of cans, he will get $110.

Stefani received a loan for $2,000 and now has acquired $720 in interest. If she pays an annual interest of 4.5% on the amount borrowed. how much time has elapsed since Stefani received the loan?
Answer:
8 years.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.5%/100 = 0.045 per year,
then, solving our equation
t = 720 / ( 2000 × 0.045 ) = 8
t = 8 years
The time required to
accumulate simple interest of $ 720.00
from a principal of $ 2,000.00
at an interest rate of 4.5% per year
is 8 years.

a number d minus 2 is less than -1 as an inequality
Answer:
(d-2) <-1
Step-by-step explanation:
The number be d. d minus 2 means (d-2).
(d-2) is less than -1.
It means,
(d-2) <-1
It is the required inequality.
So,
Adding 1 both sides.
d-2+1 <-1+1
d-1<0
or
d<1
Hence, this is the required solution.

Find the slope-intercept form of the equation of the line which contains the points (-2, 5) and (3, 20).
Answer:
y = 3x - 11
Step-by-step explanation:
First, use the y2-y1/x2-x1 format to find the slope: 20 - 5/3 - (-2)(Note: change 3 - (-2) to 3 + 2 to make it easier for you)
Simplify 15/5.Your slope would be 3/1 or 3.
Now use the slope-intercept format: y = mx + b(Use either the first point or second point, I chose the first)
5 = 3(-2) + b
Multiply 3 and -2, which is -6.Subtract 5 from -6: -6 - 5 = -11Your y-intercept is -11.

whats 40 = 1.6m ? help please
Answer:
2.5
Step-by-step explanation:
Divide each side by 1.6 to get m alone, thus getting the answer, so 1.6m/1.6 and 40/1.6
The solution of the equation 40 = 1.6 m is m is equals to 25.
Given Equation:
40 = 1.6m
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
First, write the decimal 1.6 in fraction as 16/10.
So, the equation can be written as
40 = 16/10 (m)
40 x 10 = 16m
400 = 16 m
Now, divide both side of equation by 16
400/ 16= 16 m/ 16
25 = m
Therefore, the value of m is 25.

Suppose that IJK is isosceles with base IJ.
Suppose also that m<1 = (3x +18) and m
Find the degree measure of each angle in the triangle.
Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.

Which of the following situations represent linear growth? Check all of the boxes that apply.
Martin’s savings account increases because he deposits $25 each week.
Cali’s pay increases by 3% per year.
Each week, an athlete getting into shape loses 2 pounds.
Mei-Lin earns $9 an hour at her job.
Answer:
A, C, and D.
Step-by-step explanation:
The situations that represent linear growth are:
a) Martin's savings account increases because he deposits $25 each week.
d) Mei-Lin earns $9 an hour at her job.
Given are conditions, we need to check which of them shows a linear growth,
Linear growth refers to a constant increase in a variable over time or with respect to another factor.
In both situations (a) and (d), the variables involved change at a constant rate.
In situation (a), Martin's savings account increases by $25 each week. This represents linear growth because the savings account balance is increasing by a fixed amount ($25) on a regular basis (each week).
In situation (d), Mei-Lin earns $9 an hour at her job. This also represents linear growth as the amount Mei-Lin earns increases at a fixed rate ($9) per unit of time (hour).
On the other hand, situations (b) and (c) do not represent linear growth:
In situation (b), Cali's pay increases by 3% per year. This represents exponential growth, not linear growth, because the percentage increase is applied to the current value each year, resulting in a compounding effect.
In situation (c), an athlete getting into shape loses 2 pounds each week. This represents a constant rate of change, but it is not linear growth because the weight loss is decreasing over time.
As the athlete loses weight, the rate of loss may decrease due to factors like metabolism or diminishing returns.
Hence the correct options are a) and d).

Answer: x= 2 /9
Step-by-step explanation:
Patrick had $10. Then, he saved $3.75 each week for 5 weeks. How much money does he have
now?
Answer:
Step-by-step explanation
$3.75x5=18.75
18.75+10=$28.75
Step-by-step explanation:
So he starts with 10. That would be our y-intercept. That means that 3.75 is the slope because he saves that amount of money each week. So the equation would be y = 3.75x + 10.
The x represents the number of weeks (5), so we will plug that into the equation (y = 3.75(5) + 10).
Multiply 5 and 3.75 to get 18.75
Add 10 to get 28.75
therefore the answer is 28.75Show work

The Y-Intercept is where the line on the coordinate plane meets the y axis which in this case is 2
Answer:
A. (0, 2)
Step-by-step explanation:
So first things first, you will want to either put the line on a graph by hand or, in a graphing calculator, I recommend DESMOS
the table is a set of coordinates so
(-4, -18) (-2.5, -10.5) (-.4, 0) (0, 2) (2, 12)
Then you'll put these coordinates into a graph and the point you see touching the y-line is your answer, (0, 2)

What is the x intercept of the graph of the inequality 2x + 3y > 12
Answer: x intercept = 6
This is the location (6,0)
===============================================================
Explanation:
I assume you're talking about the boundary line of the inequality. The boundary line equation is 2x + 3y = 12
To find the x intercept, plug in y = 0 and solve for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 12/2
x = 6
The boundary line 2x+3y = 12 crosses the x axis at x = 6.
We can say the x intercept is x = 6. This is the location (6,0).
Side note: the y intercept is y = 4, which is found by plugging in x = 0 and solving for y.

Answer
Answer:
[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}+C[/tex]
Step-by-step explanation:
I notice you have a dx at the end of the equation, this leads me to believe this is an integral. With no bounds of integration, I will solve for the indefinite integral. I will also interpret your equation as follows:
[tex]\int \:2+5x+\frac{1}{2}x^3dx[/tex]
Sum rule tells us:
[tex]\int \:2dx+\int \:5xdx+\int \frac{1}{2}x^3dx[/tex]
From this we get:
[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}[/tex]
Don't forget to add the constant!
[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}+C[/tex]
A cone has a base area of 20 m and a volume of 160 m. Find the height of the cone
Given:
Base area of cone =20 m²
Volume of the cone = 160 m³
To find:
The height of the cone.
Solution:
We know that, the volume of a cone is
[tex]V=\dfrac{1}{3}Bh[/tex]
Where, B is the base area and h is the height of the cone.
Putting V=160 and B=20, we get
[tex]160=\dfrac{1}{3}(20)h[/tex]
[tex]480=20h[/tex]
[tex]\dfrac{480}{20}=h[/tex]
[tex]24=h[/tex]
Therefore, the height of the cone is 24 m.
Rachel received 5/8 of the 72 vote cast for class president. How many votes did she receive
Answer: Rachel recieved 45 votes.
Step-by-step explanation: Any easy way to solve this is to has the demonimator equal the total amount of votes. So in the questions, 8 is the denominator and 72 is the total amount of votes. To get from 8 to 72, you need to multiple 8 by 9. And whatever you do to the denominator, you must do to the numerator. So, 5 times 9 equal 45 which is the number of votes Rachel recieved.
