A recycling center was offering cash for different types of recyclables. For each pound of copper they paid $1.48, for each pound of aluminum they paid $1.55, and for each pound of plastic they paid $0.30. Jesse took in 50 pounds of copper, 15 pounds of aluminum and 10 pounds of plastic. How much money was he paid for his recyclables?
Answer:
100.25
Step-by-step explanation:

What is the perimeter of the rectangle?
Answer:
P = 20x - 12
Step-by-step explanation:
The Perimeter of a Rectangle is 2l + 2w, where l is the length and w is the width.
Now, let's substitute the given values.
2(8x - 9) + 2(2x + 3)
= 16x - 18 + 4x + 6

If a quadratic function has the rule
f(x) = (x – h)? + k,
what will cause a horizontal translation?
A, changing the value of h
B, changing the value of k
A. Changing the value of h will cause horizontal translation.
What is transformation ?Transformations are of many types like translation, rotation, reflection and dilation.These transformations are of two types rigid transformation where the shape and size of image and pre image remains same and another one is non-rigid transformation in which size changes but shape of doesn't change.
We know that a quadratic function can be represented by a 2D co ordinate which has x axis and y axis.
Given a function f(X) = ( x - h) + k will cause horizontal transformation of h units to the left.

Archie is taking a course in probability theory. Discussion sessions with the class TA (teaching assistant) conflict with Archie's trips to the beach. Archie has to decide between attending TA sessions, which might help him do better in the probability course, and going to the beach.
Archie learns that 93% of past students who did not attend TA sessions received a grade of B or below in the course. Archie also learns that 11% of past students received a grade higher than B. After some thought, Archie decides to attend the TA sessions. Not all of his classmates share his decision; in fact, only 4 out of every 18 of his classmates attend discussion sessions with the TA. Compute the probability that Archie will receive a grade higher than a B in the course.
Answer:
The probability that Archie will receive a grade higher than a B in the course is 0.2164.
Step-by-step explanation:
We are given that Archie learns that 93% of past students who did not attend TA sessions received a grade of B or below in the course. Archie also learns that 11% of past students received a grade higher than B.
Let B = event that the student received a grade higher than B.
and T = event that the student discussion sessions with the TA.
So, P(B) = 0.11 and P(T) = [tex]\frac{4}{18}[/tex] = 0.22
Also, the probability that the students who did not attend TA sessions received a grade of B or below in the course = P(B'/T') = P(not B/not T) = 0.92
Now, we have to find the probability that Archie will receive a grade higher than a B in the course given he attended the discussion sessions with the TA = P(B/T)
As we know that the conditional probability formula is given by;
P(B/T) = [tex]\frac{\text{P}(\text{B} \bigcap \text{T})}{\text{P(T)}}[/tex]
Now, as it is given that P(not B/not T) = 0.92
So, [tex]\frac{\text{P}(\text{not B} \bigcap \text{not T})}{\text{P(not T)}} =0.92[/tex]
[tex]\frac{\text{P}(\text{not B} \bigcap \text{not T})}{1 - \text{P(T)}} =0.92[/tex]
[tex]\frac{\text{P}(\text{not B} \bigcap \text{not T})}{1 - 0.22}} =0.92[/tex]
[tex]{\text{P}(\text{not B} \bigcap \text{not T})} =0.92\times 0.78[/tex]
[tex]{\text{P}(\text{not B} \bigcap \text{not T})}[/tex] = 0.7176
Also, [tex]{\text{P}(\text{ B} \bigcup \text{ T})}= 1 - {\text{P}(\text{not B} \bigcap \text{not T})}[/tex]
[tex]{\text{P}(\text{ B} \bigcup \text{ T})}[/tex] = 1 - 0.7176 = 0.2824
Now, the formula for [tex]{\text{P}(\text{ B} \bigcup \text{ T})}[/tex] is given by;
[tex]{\text{P}(\text{ B} \bigcup \text{ T})} = \text{P(B)} + \text{P(T)} - {\text{P}(\text{ B} \bigcap \text{ T})}[/tex]
0.2824 = 0.11 + 0.22 - [tex]\text{P(B} \bigcap \text{T})[/tex]
[tex]\text{P(B} \bigcap \text{T})[/tex] = 0.33 - 0.2824 = 0.0476
Now, the required probability P(B/T) = [tex]\frac{\text{P}(\text{B} \bigcap \text{T})}{\text{P(T)}}[/tex]
= [tex]\frac{0.0476}{0.22}[/tex] = 0.2164
Hence, the probability that Archie will receive a grade higher than a B in the course is 0.2164.

Parallelogram JKLM has angle measures J(2 x +9) and M(6 x -1) determine the measure of angle k
Answer:
Step-by-step explanation:
The sum of opposite angle and sides of a parallelogram is 180 . If a parallelogram JKLM has angle measures J(2 x +9) and M(6 x -1), then <J + < M = 180
Substitute:
2 x +9+6x-1 = 180
collect like terms;
2x+6x+9-1 = 180
8x+8 = 180
8x = 180-8
8x = 172
x = 172/8
x = 21.8°
For the shape to be a quadrilateral, then the measure of angle k must 128 degrees
For quadrilateral PQRS to be an actual quadrilateral, then:
[tex]K = M[/tex] --- opposite angles of quadrilateral[tex]J + M= 180[/tex] --- adjacent angles of quadrilateral[tex]J + M = 180[/tex] implies that:
[tex]2x + 9 + 6x -1 = 180[/tex]
Collect like terms
[tex]2x + 6x = 180 -9 +1[/tex]
[tex]8x = 172[/tex]
Divide both sides by 8
[tex]x = 21.5[/tex]
We have:
[tex]K = M[/tex]
This becomes
[tex]K = 6x -1[/tex]
Substitute 21.5 for x
[tex]K = 6\times 21.5 -1[/tex]
[tex]K = 129 -1[/tex]
Subtract 1 from 129
[tex]K = 128[/tex]
Hence, the measure of angle K must be 128 degrees

Dave buys a baseball for $15 plus an 8% tax. Mel buys a football for $20 plus an 8% tax. What is the difference in the amount Dave and Mel paid, including tax? Round your answer to the nearest cent.
Answer: $5.40
Step-by-step explanation:
First we will find the tax amount for Dave by multiplying 8% by 15.
8% * 15 = 1.2
Now add it to the original price of the baseball which is 15.
15 + 1.2= 16.20 This means Dave paid $16.20 in total.
Now find the tax amount for Mel.
20 * 8% = 1.6
Add 1.6 to the original price which is $20.
1.6 + 20 = 21.60
Mel also paid $21.60 in total.
To find the difference we need to subtract the lowest amount from the highest amount.
21.60 - 16.20 = 5.40
