Weighted average is the average of a set using different weight for each element in the set. The final grade when homework and test scores are 59 and 64 is 62.35
Given that:
[tex]Homework = 59[/tex]
[tex]Test = 64[/tex]
The test score is greater than the homework score. So, the test will be weighted using 67%, while the homework will be weighted using 33%.
The final grade is calculated as follows:
[tex]Grade = 67\% \times Test + 33\% \times Homework[/tex]
So, we have:
[tex]Grade = 67\% \times 64 + 33\% \times 59[/tex]
[tex]Grade = 42.88 + 19.47[/tex]
[tex]Grade = 62.35[/tex]
Hence, the final grade is 62.35

The cost to rent a van is $19.50 per day plus $0.25 per mile. If you have $157 to
rent a van, what is the number of miles that you can drive if you want to rent the van
for 2 days and you want to stay below your budget? Let m represent the number of
miles.
Answer:
92 miles
Write an inequality for the total cost of the rental.
Cost of the rental = 19.50+0.25x<=44
where x is the number of miles driven.
Subtract 19.50 from both sides.
0.25x<=44-19.50
0.25x<=24.5
x<=24.5/0.25
x<=98

You are offered two jobs. One with a yearly salary of $51,670, and the other an hourly
job with a rate of $26 per hour. Both require you to work for 45 hours a week. How
much more will you make by taking the hourly job?
Answer:
$9170 per year , or ≈ $3.92 per hour
Step-by-step explanation:
We can solve this by putting both of these in terms of yearly salary and going from there.
The first job is already in terms of yearly salary.
The hourly rate job is $26 per hour. There are 45 hours worked per week, and we add $26 for each hour. Another way of saying this is 26 * 45 = total amount earned for the week = $1,170 .
There are 52 weeks in a year, and you make $1,170 per week on the hourly job. This means that over 52 weeks, you will earn 1170 * 52 = 60840. This is the yearly rate for the second job.
The difference between the two jobs is
60840 - 51670 = $9170 per year. Dividing by 52 to get the weekly gain, we get ≈ $176.35 more for the hourly job each week. Dividing by 45 to get the hourly gain, we get ≈ $3.92 dollars from taking the second job

What is the equation of a line that passes through (4, 3) and has a slope of 2?
Oy= 2x – 11
Oy=2x-1
Oy= 22 – 5
y= 22 - 7
Answer:
[tex]y=2x-5[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
We're given that the slope is 2. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=2x+b[/tex]
Now, to solve for the b, plug in the point (4,3):
[tex]3=2(4)+b\\3=8+b\\3-8=b\\-5=b[/tex]
Therefore, the y-intercept is -5. Plug this back into [tex]y=2x+b[/tex] as b:
[tex]y=2x+(-5)\\y=2x-5[/tex]
I hope this helps!
(x,y) = (4,3)
m = 2
Solution :-We know that
y = 2x + b
3 = 2(4) + b
3 = 8 + b
3 - 8 = b
-5 = b
Now
We need to find the equation
Equation = y = 2x + b
We have
x = x
y = ?
b = -5
y = 2(x) + (-5)
y = 2(x) - 5
y = 2x - 5

Someone help me answer this please y = 6х – 2х^2
Answer:
[tex]0=x[/tex], [tex]3=x[/tex]
Step-by-step explanation:
One is given the following equation:
[tex]y=6x-2x^2[/tex]
Factor this expression:
[tex]y=-2x(x-3)[/tex]
Set the equation equal to (0), then use the zero-product property to solve for (x). The zero product property states that any number times zero equals zero. Thus, one can apply this here to solve for (x):
[tex]0=-2x(x-3)[/tex]
[tex]0=-2x[/tex] [tex]0=x-3[/tex]
Inverse operations,
[tex]0=-2x[/tex] [tex]0=x-3[/tex]
[tex]0=x[/tex] [tex]3=x[/tex]

If x = 2y then, 5y - x in terms of y is equal to 3y and when y = 2, the value of 5y - x is 6.
To solve 5y - x in terms of y, we need to substitute the value of x in terms of y. Given that x = 2y, we can replace x with 2y in the expression 5y - x:
5y - x = 5y - (2y)
Now we simplify the expression by subtracting 2y from 5y:
5y - (2y) = 3y
Therefore, 5y - x in terms of y is equal to 3y.
To find the value of the expression when y = 2, we substitute y = 2 into the expression:
3y = 3 * 2 = 6
Thus, when y = 2, the value of 5y - x is 6.

16. There are 36 tables set up for the graduation reception. Each table is
8 feet long. The tables will be covered with paper tablecloths that extend
an extra 3 inches over each end (so they can be taped underneath). What
is the total length of paper needed to cover all the tables?
We have that the total length of paper needed to cover all the tables is
[tex]X=288.5ft[/tex]
From the question we are told that:
Number of tables [tex]n=36[/tex]
Length of table[tex]l=8[/tex]
Extension [tex]e=3 inch =>0.25feet[/tex]
Generally, the equation for the Total length tables is mathematically given by
[tex]l_t=n*l\\\\l_t=36*8[/tex]
[tex]l_t=288ft[/tex]
Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be
[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]
[tex]X=288.5ft[/tex]
In conclusion
The total length of paper needed to cover all the tables is
[tex]X=288.5ft[/tex]

If 2 + 2 could = 22, how can you make 2 + 2 = 5?
Answer:Of the ones mentioned here, I'd say that 3, redefine addition, is the easiest way to use and work with to get lots of self consistent theories that have 2 + 2 = 5.
Step-by-step explanation:
First, it’s easy to prove that 2 + 2 =4. You just need the rule x + Sy = S(x + y) where Sx means the successor of x, or x + 1. With some more steps, with simple natural axioms, you can also derive a contradiction from 2 + 2 = 5. Proof indented so it’s easy to skip.
