- 28
What is the y-intercept of the line?
The y-intercept of the line is y = 2
What is an intercept?
A line's x-intercept and y-intercept are the points at which the x- and y-axes, respectively, are crossed.
Here,
A linear function has the following equation:
y = mx + b
Where m is the slope and b is the y-intercept, which is the value of y when x = 0.
We have given three points:
(-28, -54)
(-21, -40)
(-14, -26)
We use two of them to construct a system, to find values for m and b.
(-28, -54)
This means that when x = - 28 , y = - 54
so, y = mx + b
- 54 = - 28m + b
28m = b + 54
m = (b + 54)/28
Now, we have x = -21, y = -40
so, y = mx + b
- 40 = - 21m + b
we put the value of m here
- 40 = - 21 {(b + 54)/28} + b we get,
7b - 1134 = - 40 × 28
b = 2
Hence, the y-intercept of the line is y = 2

For a $250,000 mortgage, with an interest rate of 6% paid over 25 years, the monthly payment is $1,610.75. After one month, what is the balance of the loan?
Round your answer to the nearest dollar.
Do NOT round until you calculate the final answer.
The balance on the loan after a month is $623389.25.
How to calculate the interest?The following can be deduced from the information given:
Principal = $250000
Time = 25
Rate = 6%
Interest = (Principal × Rate × Time) / 100
Interest = (250000 × 6 × 25) / 100
Interest = $375000
The total amount will be:
= Principal + Interest
= $250000 + $375000
= $625000
The balance of the loan will be:
= Amount - One month payment
= $625000 - $1,610.75
= $623389.25

How many hours did Anita work and what was her net pay ? Anita works 31 hours next week what is her gross pay total amount of deductions and net pay assuming the same percentage is taken out for each deductions during the next pay period ?
For the gross pay of $238.61 and given deduction Anita's net pay is equal to $181.59 at the rate of $9.45 per hour and she works for 25.25 hours.
When Anita works for 31 hours with the given conditions her gross pay and net pay is equal to $292.95 and $235.93 respectively.
As given in the question,
a. Anita get pay per hour = $9.45
Gross pay received by Anita = $238.61
Deductions :
Federal tax = $28.63
Society tax : $14.79
Medicare : $3.46
State tax : $10.14
Total deduction = $ ( 28.63 + 14.79 + 3.46 + 10.14 )
= $57.02
Net pay = Gross pay - total deduction
= $ ( 238.61 - 57.02 )
= $ 181.59
Let us consider Anita works for 'h' hours at the rate of $9.45,
9.45h = 238.61
⇒ h = 238.61/ 9.45
⇒ h = 25.25 hours
b. When Anita works for 31 hours
Her gross pay = 31 × 9.45
= $ 292.95
Deductions are same
Net pay = $ ( 292.95 - 57.02 )
= $ 235.93
Therefore, for the gross pay of $238.61 and given deduction Anita's net pay is equal to $181.59 at the rate of $9.45 per hour and she works for 25.25 hours.

race. Chris runs his part of the race in 12.35 seconds, Kiona takes
13.12 seconds, and Seiko takes 11.91 seconds.
a. The team wants to break the school record of 48.92 seconds. How
fast will Dwayne have to run?
Dwayne have to complete the race in 11.53 second or the speed of Dwayne is 11.53 second/ 100 meter.
What is speed of an object?
Speed, expressed in terms of meters per second, is the rate at which an object's location changes. An item moves one meter in one second, for instance, if it starts at the origin and moves three meters in three seconds. The formula for speed is straightforward: time divided by distance.
Given that Chris, Kiona, Seiko, and Dwayne each run 100 meters in a relay
race. Chris runs his part of the race in 12.35 seconds, Kiona takes
13.12 seconds, and Seiko takes 11.91 seconds.
The total time that is taken by Chris, Kiona, and Seiko is (12.35 + 13.12 + 11.91) seconds = 37.38 seconds.
The team wants to break the record of 48.92 seconds.
To break the record, they should complete the race in 48.91 seconds.
Thus Dwayne have to run 100 meters in ( 48.91 - 37.38) = 11.53 seconds.

The correct statement regarding the critical value of the t-distribution is given as follows:

t = d/220 is the equation that shows how many hours (t) a trip takes in terms of the trip's distance (d).
Define the relationship between distance, speed, and time.Speed is calculated as follows: speed = distance/time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is recorded in seconds, the units in this example will be meters per second (m/s) (s).
Let the distance be d and the time is t.
The given speed of the train = 220km/hr
Time = d/speed
t = d/220

Find the scale of a map if 4.2 cm on the map corresponds to an actual distance of 6.2 km.
Answer:
21/3100000 ≈ 1/147619
Step-by-step explanation:
You want the scale of a map on which 4.2 cm corresponds to an actual distance of 6.2 km.
ScaleThe scale of a drawing is the ratio of drawing distance to actual distance. It can be expressed a couple of ways. We can write the given scale as ...
4.2 cm : 6.2 km
or, we can reduce it to ...
2.1 cm : 3.1 km
Often, we like to have a single unit of map distance in this ratio, which would make it be approximately ...
1 cm : 1.47619 km
FractionAnother way to write the scale of a map is as a fraction.
(4.2 cm)/(6.2 km) = (0.042 m)/(6200 m) = 21/3100000
When this is expressed as a unit fraction, the denominator is a repeating decimal with a 6-digit repeat. We can round it to ...
≈ 1/147619 . . . . map scale
The scale of the map is ...
21/3100000 ≈ 1/147619 or 2.1 cm : 3.1 km or ≈ 1 cm : 1.47619 km

What is Area?
Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.
On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.
Consider your square as being composed of smaller unit squares. The number of unit squares necessary to completely cover the surface area of a specific 2-D shape is used to calculate the area of a figure. Some common units for measuring area include square cms, square feet, square inches, square meters, etc.
Let Width= x feet
so, as per question Length = x+6 feet
Area = Length x Width = x(x+6) = [tex]x^{2} +6x[/tex]
According to the question each side is increased 6 feet
New Length = x+12 feet
New Width = x+6 feet
New Area = Length x Width[tex]= 2x(x+6)[/tex] <the area is multiplied by 2>
Length x Width=[tex](x+6)(x+12) = 2x(x+6)[/tex]
x+12=2x

(Round off your answers to the nearest integer.)
The population means that the number of years worked is 14, and 73% of employees worked for the company for at least 10 years.
The mean is calculated by dividing the number of employees by the number of years of service. The total number of years of service is 417, hence the average will be
The average years worked = 417/30 = 13.9 ≈ 14 years
The % of workers who have worked there for at least ten years is calculated by calculating the number of employees who have ten or more years of service and dividing that number by the total number of employees.
The final result is presented as a percentage will be:
(10 years or more)/(total number) = 22/30 = 0.73 = 73%
Thus, the population means that the number of years worked is 14, and 73% of employees worked for the company for at least 10 years.
