Fred's overtime pay is $16.50 an hour. He put in extra time this week on Monday and Thursday. The equation is $123.75-4 times the x value =h and h value is 57.75 and the working hours are 3.5 hours.
Given that,
Fred's overtime pay is $16.50 an hour. He put in extra time this week on Monday and Thursday. He put in four hours of extra on Monday. He received $123.75 in overtime compensation in total for the week.
We have to determine how many overtime hours, h, Fred worked on Thursday, write an equation and solve it.
We can write the equation as
$123.75-4 times the x value =h
Here,
x value is $16.50
We get,
$123.75-4×$16.50=h
h=57.75
To check hours working
57.75/16/50
=3.5 hours.
Therefore, the equation is $123.75-4 times the x value =h and h value is 57.75 and the working hours are 3.5 hours.

The ratio of one variable quantity to another that is always constant and to which it is proportional is known as the constant of proportionality then the constant of proportionality exists r = 1.6.
What is meant by constant of proportionality?The ratio of one variable quantity to another that is always constant and to which it is proportional is known as the constant of proportionality.
Given
x y
0.5. 0.8
1. 1.6
3. 4.8
25. 40
To estimate the constant of proportionality uses the following formula:
y = r x
Where r is the constant of proportionality;
Simplify the value of r, we get
r = y/x
Substitute the values of x = 0.5 and y = 0.8, in the above equation then
r = 0.8/0.5
r = 1.6
When x = 1 ; y = 1.6
r = 1.6/1
r = 1.6
When x = 3; y = 4.8
r = 4.8/3
r = 1.6
When x = 25 ; y = 40
r = 40/25
r = 1.6
The value of r exists constant.
Therefore, the constant of proportionality exists r = 1.6.

The current total bid for Empire design is $3,060,000The current total bid for Build-EM-UP-CO is $ 3,120,000.What is a bid?Bidding is an individual or business's offer to establish a price for a product or service or a demand that something be done. Bidding is a method of determining the price or worth of something. Bidding may be done by a person who is influenced by a product or service in a given setting.
The calculations are given as follows:
Given:
Proposal of Empire design:
$30000 x b
$ 60000/ I beam
Proposal of Build-EM-UP-CO.
$32000 x b
$ 40000/ I beam
Empire Design
Since b = 9ft; and number of I beams = 6, Hence
Total bid = (300,000 * 9) + (60,000 * 6)
= $3,060,000
Build-EM-UP-CO.
Recall that b = 9ft; and number of I beams = 6, Hence
Total Bid = (320,000 * 9) + (40,000 * 6)
Therefore,
Total bid = $3,120,000.

Quadrilateral ABCD is translated 6 units right and 5 units down to create quadrilateral EFGH. Determine the correct orientation and location of quadrilateral EFGH.
The translation of Quadrilateral ABCD with coordinates A(-3, 4), B(1, 3), C(3, 6), and D(1, 6) using the given transformation rule is; E(3, -1), F(7, -2), G(9, 1), H(7, 1)
What is the translation?
We are given the vertices of Quadrilateral ABCD as;
A(-3, 4), B(1, 3), C(3, 6), and D(1, 6)
Now, we are told that it is first translated right by 6 units. This means that we would add 6 units to each x-value to get;
A'(-3 + 6, 4) = A'(3, 4)
B'(1 + 6, 3) = (7, 3)
C'(3 + 6, 6) = C'(9, 6)
D'(1 + 6, 6) = D'(7, 6)
It is now translated by 5 units downwards and we subtract 5 from each y-value and this gives us;

You invested $101 and received $106.05 after one year. What was the interest rate?
The rate of interest was 5%.
The rate of interest and simple interest can be related through the formula -
S.I. = PRT/100, where S.I. stands for simple interest, P stands for principal, R stands for rate of interest and T stands for time.
Amount = Principal + Interest
Interest = 106.05 - 101
Performing subtraction on Right Hand Side of the equation
Interest = $5.05
Rate of interest = (5.05×100)/(101×1)
Performing multiplication in numerator and denominator
Rate of interest = 505/101
Performing division
Rate of interest = 5
Therefore, to earn $106.05 from $101 in one year, the rate of interest should be 5%.

In the figure ZX = 2x + 1 YW = 3x - 1 and YX = 1, find perimeter of VYZ
The perimeter of triangle VYZ is 12 units.
How to find the perimeter of a triangle?The perimeter of a triangle is the sum of the whole sides of the triangle.
In other words, the perimeter of a triangle is the total distance covered by its boundaries or the sides.
Therefore,
perimeter of ΔVYZ = VY + ZY + ZV
Therefore,
VY = ZY = ZV = XW
Hence,
YW = YX + XW
Therefore,
XW = YW - YX
YW = 3x - 1
YX = 1
Hence,
XW = 3x - 1 - 1
XW = 3x - 2
Therefore,
perimeter of ΔVYZ = 3x - 2 + 3x - 2 + 3x - 2
perimeter of ΔVYZ = 9x - 6
ZX = YW
2x + 1 = 3x - 1
2x - 3x = - 1 - 1
-x = -2
x = 2
Therefore,
perimeter of ΔVYZ = 9(2) - 6

The dimension of a matrix is given as (the number of rows it has, say a) x (the number of columns it has, say b) [read as a by b].. The given matrix has 4 rows and 3 columns, so its dimension is 4x3.
For a matrix A of dimension axb to be multiplied with a matrix B of dimension cxd, the number of columns of matrix A should be equal to the number of rows of matrix B, that is b = c should be satisfied. In this case both matrices are of the same dimension 2x3 but 3 (number of columns in first matrix) is not equal to 2 (number of rows in second matirx). So these matrices cannot be multiplied as their dimensions do not match.

find the area. please explain how to get it
Answer:
Step-by-step explanation:
(the small double lines like = means that the length of those sides are all same)
So, if one length is considered as x
the other two will also be x
we see that the length of one side is given which is 27
to find x
x + x + x = 27
3x = 27
so, x = 27/3
x = 9m
(the small vertical single line means that those sides are equal)
so if one side is y, the other two are also y
so , y + y+ y = 30
3y = 30
y = 10m
If we imagine the stairs to be made of small rectangles of length 10m and base 9m , finding area will be easier.
we will see that there are 9 rectangles in total
area of rectangle = length x base
so, area of 1 rectangle = 9x10
= 90[tex]m^{2}[/tex]
so area of 9 identical rectangles = 9 x 90

A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream took 60 hours. Use this information to fill in the following blanks. Note: Express your answers as integers.
The speed of the boat in still water is 6miles/hour miles per hour.
The speed of the current is 3miles/hour miles per hour.
The distance travelled by the boat downstream(with the flow current of river) is 240 miles.
The distance travelled by the boat upstream(Against the flow current of river) is 240 miles.
Time taken to travel downstream = 20 hours.
Time taken to travel upstream = 60 hours.
Let us say the velocity of the boat is V and the velocity of the current flow of river is U.
The relative velocity of boat with respect to ground while going downstream is,
velocity of boat in downstream = V + U.
As we know,
Velocity = distance/time
Putting values of downstream motion,
V + U = 240/20
V + U = 10
Let us say this is our equation 1.
The relative velocity of boat with respect to ground while going upstream is,
velocity of boat in upstream = V - U
As we already know,
Velocity = distance/time
Putting the values of upstream motion,
V - U = 240/60
V - U = 3
Let us say this is our equation 2.
Now, on adding equation 1 and 2.
V+U+V-U = 10 + 3
2V = 13
V = 6.5 miles per hour.
Rounding off to the nearest integer,
V = 6 miles/hour.
Putting V = 6.5 miles/hour in equation 1,
6.5 + U = 10
U = 3.5 miles/hour.
Rounding off to the nearest integer,
U = 3 miles/hour
The velocity of river current is 3 miles/hour and velocity of boat is 6miles/hour.
