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.

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.
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 28.75Help me out here ✏️ Mathematics

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).

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.

If R is the midpoint of PS with PR=6x+16 and RS=-26 then find PS
Answer:
PS = 116
Step-by-step explanation:
Given:
PR = 6x + 16
RS = 12x - 26
Required:
Find PS
Solution:
Since R is the midpoint of PS, therefore,
PR = RS
6x + 16 = 12x - 26
Collect like terms
6x - 12x = -16 - 26
-6x = -42
Divide both sides by -6
x = -42/-6
x = 7
✔️PS = PR + RS (segment addition postulate)
PS = 6x + 16 + 12x - 26
Plug in the value of x
PS = 6(7) + 16 + 12(7) - 26
PS = 42 + 16 + 84 - 26
PS = 116

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.

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15
Answer:
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
Slope = m & y-intercept = b
x - 5y = 15
-5y = -x + 15
y = [tex]\frac{-1}{-5}x + \frac{15}{-5}\\\\[/tex]
[tex]y = \frac{1}{5}x - 3[/tex]
so, slope = 1/5 ; (-5 , 7)
y -y1 = m(x -x1)
[tex]y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8[/tex]

Make a conditional relative frequency table for the columns of movie type. Determine which statement has the strongest association.
Do you prefer watching a comedy, a drama, or a thriller movie?
Comedy Drama Thriller Row Totals
Males 35 12 75 122
Females 46 65 18 129
Column Totals 81 77 93 251
Males prefer comedy movies.
Females prefer drama movies.
Males prefer thriller movies.
Females prefer thriller movies.
The statement which has the strongest association is Males prefer thriller movies.
To obtain which statement has the strongest association, we calculate the probability of each given statement and select that which has the highest probability value.
• probability of Males prefer comedy movies :
n(males who prefer comedy) / n(males)
= 35 / 122 = 0.287
• probability of Females prefer drama movies :
n(Females who prefer drama) / n(females )
= 65 / 129 = 0.504
• probability of Males prefer thriller movies.
n(males who prefer prefer thriller ) / n(males)
= 75 / 122 = 0.615
• probability of Females prefer thriller movies.
n(females who prefer prefer thriller ) / n(females)
= 18 / 129 = 0.140
Comparing the probabilities obtained, Males prefer thriller has the highest probability, thus the strongest association.

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.
