Answer:
Monthly payment is $247.53
Step-by-step explanation:
Firstly, we need to calculate the total amount to be paid back
we have this by calculating using the compound interest formula;
That will be;
A = P( 1 + r/n)^nt
where A is the amount to be paid back
P is the amount borrowed = $8,000
r is the interest rate = 3.6% = 3.6/100 = 0.036
n is the number of times we are compounding per year; since it is monthly, this is 12
t is the number of months which is 3
Substituting these values, we have
A = 8000( 1 + 0.036/12)^(12 * 3)
A = 8000(1 + 0.003)^36
A = 8000( 1.003)^36
A = $8,910.94
To know the monthly payment, we divide this by the number of months
That will be;
$8,910.94/36
= $247.53

Answer:
Parallel: y = -5x - 34 ; Perpendicular: y = 1/5x - 14/5
Step-by-step explanation:
Lines that are parallel have the same slope. Lines that are perpendicular have opposite reciprocal slopes. (Ex. 1/3 ⇒ -3)
We need to substitute the given values into the point-slope form equation.
Parallel:
y + 4 = -5(x + 6)
y + 4 = -5x - 30
y = -5x - 34
Perpendicular:
y + 4 = 1/5(x + 6)
y + 4 = 1/5x + 6/5
y = 1/5x - 14/5

A rectangular field is 90 meters wide and 125 meters long.
Give the length and width of another rectangular field that has the same perimeter but a larger area.
Answer:
The length and the width of another rectangle are 115 meters and 100 meters
Step-by-step explanation:
Let us solve the question
∵ A rectangular field is 90 meters wide and 125 meters long
∴ The length = 125 m
∴ The width = 90 m
∵ The perimeter of the rectangle = 2(length + width)
→ Substitute the value of the length and the width in the rule
∴ The perimeter of the rectangle = 2(125 + 90)
∴ The perimeter of the rectangle = 430 m
∵ The area of the rectangle = length × width
→ Substitute the value of the length and the width in the rule
∴ The area of the rectangle = 125 x 90
∴The area of the rectangle = 11250 m²
We need to find another rectangle with the same perimeter but larger in area, to do that make the length and width closed in values
∵ The length = 125 m and the width = 90 m
→ Subtract 10 from the length and add it to the width
∴ The new length = 125 - 10 = 115 m
∴ The new width = 90 + 10 = 100 m
→ Find the perimeter and the area of the new rectangle
∵ The perimeter of the new rectangle = 2(115 + 100)
∴ The perimeter of the new rectangle = 430 m ⇒ the same perimeter
∵ The area of the new rectangle = 115 × 100
∴ The area of the new rectangle = 11500 m² ⇒ larger than the original area
∴ The length and the width of another rectangle are 115 m and 100 m

If you apply the changes below to the quadratic parent function, f(x) = what is the equation of the new function? Shift 1 unit right. Vertically stretch by a factor of 5. Reflect over the x-axis.
Answer:
f(x)=-5(x-1)^2
Step-by-step explanation:
The given parent function is: f(x)=x^2
If we shift to the right by 1 unit, the function becomes: f(x)=(x-1)^2
If we stretch by a factor of 5, the function becomes, f(x)=5(x-1)^2
Finally reflecting over the x-axis gives: f(x)=-5(x-1)^2

Which ratio is equivalent to 9 : 180?
A. 5 : 200
B. 12 : 240
C. 10 : 400
D. 8 : 560
The equivalent ratio of 9:180 is 12:240.
9:189 = 1/20 = 1:20
12:240 = 12/240 = 1/20
Option B is the correct answer.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
9 : 180
We will simplify it into its simplest form.
180 = 9 x 20
Now,
9 : 180
This can be written as,
= 9 / 180
= 9 / (9 x 20)
= 1/20
= 1:20
Now,
A.
5:200
= 5/200
Write along with its common factor.
= 5 / (5 x 40)
= 1/40
= 1:40
B.
12:240
= 12 / 240
Write along with its common factor.
= 12 / (12 x 20)
= 1/ 20
= 1:20
C.
10:400
= 10/400
Write along with its common factor.
= 10/(10 x 40)
= 1/40
= 1:40
D.
8:560
= 8/560
Write along with its common factor.
= 8/(8 x 70)
= 1/70
= 1:70
Thus,
The equivalent ratio of 9:180 is 12:240.
9:189 = 1/20 = 1:20
12:240 = 12/240 = 1/20
Option B is the correct answer.

Step-by-step explanation:
What is the sum of all of the single-digit positive whole numbers that evenly divide 72?
Answer:
33
Step-by-step explanation:
So all the single-digit positive whole numbers that evenly divide 72 would be:
1 (72 / 1 = 72)
2 (72 / 2 = 36)
3 (72 / 3 = 24)
4 (72 / 4 = 18)
6 (72 / 6 = 12)
8 (72 / 8 = 9)
9 (72 / 9 = 8)
Then, 1 + 2 + 3 + 4 + 6 + 8 + 9 = 3 + 7 + 14 + 9 = 10 + 23 = 33
Kathryn has been offered a job to paint the outside of a barn. If one gallon costs $40 and covers 400 square feet. How much will it cost to paint the barn with one coat?
Answer:
The answer is below
Step-by-step explanation:
The question is not complete but I would solve a similar question:
Alexis needs to paint the four exterior walls of a large rectangular barn. The length of the barn is 80 feet, the width is 50 feet, and the height is 30 feet. The paint costs $28 per gallon, and each gallon covers 420 square feet. How much will it cost Alexis to paint the barn? Explain your work.
Solution:
The barn has four walls. Let the four walls be labeled as w, x, y and z.
The area of wall w = 80 feet * 30 feet = 2400 feet²
The area of wall x = 50 feet * 30 feet = 1500 feet²
The area of wall y = 80 feet * 30 feet = 2400 feet²
The area of wall z = 50 feet * 30 feet = 1500 feet²
The total area of the four walls = area of wall w + area of wall x + area of wall y + area of wall z
The total area of the four walls = 2400 + 1500 + 2400 + 1500 = 7800 ft²
Given that each gallon of paint can cover 420 feet². Therefore number of gallon needed is:
number of gallon needed = 7800 ft² ÷ 420 ft² per gallon = 18.57
Since the gallon must be a whole number and 18 gallons wont be enough, therefore number of gallon needed is 19 gallons.
Cost of painting = 19 gallons * $28 per gallon = $532
The distance between New Orleans and Houston is 353 miles. At 12:20 PM, a bus
leaves Houston for New Orleans at a speed of 60 mph. Forty-five minutes later, a
motorcycle leaves New Orleans for Houston at a speed of 72 mph. At what time will
the bus and the motorcycle pass each other if neither stops nor changes speed?
Answer:
3:25 pm
Step-by-step explanation:
The distance between New Orleans and Houston is : 353 miles
Departure time of the bus : 12:20 pm
Speed of the bus: 60 mph
After 45 minutes, the bus will be at a distance of : 45/60 * 60 = 45 miles
Distance remaining to cover = 353-45 = 308 miles
Speed of the motorcycle = 72 mph
Relative speed = 60 + 72 = 132 mph
Time the two will meet = 308 / 132 = 7/3 hrs
7/3 hrs = 2 hrs 20 minutes
Time the two will meet is ;
12:20 pm + 45 minutes + 2 hrs 20 minutes
= 3:25 pm
Both the bus and the motorcycle are driving opposite to each other.
From the given data, the time at which both the bus and the motorcycle will pass each other is 3:25 PM
Given that:Distance between New Orleans and Houston = 353 miles.Bus leaves Houston for New Orleans at 12:20 PM.Speed of bus = 60 mphAfter 45 minutes, the motorcycle leaves New Orleans for Houston at 72 mph.To find:The time at which both the motorcycle and the bus will pass each other.
Calculations:Let after t hour from the time when motorcycle starts, they both meet.
Then we have:
353 miles = 45 minute traveled by bus + distance traveled by bus in t hour + distance traveled by motorcycle in t time.
Since 45 minutes is three fourth of an hour, thus:
Distance traveled by bus in 45 minutes is calculated as:
[tex]D_{Bus}(45 \:\rm min) = 60 \times \dfrac{3}{4} \: \rm miles = 45 \: \rm miles[/tex]
Distance traveled by bus in t hours is:
[tex]D_{Bus}(t \: \rm hours) = 60 \times t \: \rm miles = 60t \: \rm miles[/tex]
Distance traveled by motorcycle in t hour is:
[tex]D_{motorcycle}(t \: \rm hours) = 72 \times t \: \rm miles = 72t \: \rm miles.[/tex]
Thus, we have:
[tex]353 = 60t + 72t + 45\\\\308= 132t\\\\t = \dfrac{308}{132}\\\\t= \dfrac{7}{3}\: \rm hours\\\\t=2 \: \rm hours + 20 \: \rm minutes[/tex]
Thus, time at which they meet was 12:20 PM + 45 minutes + 2 hours + 20 minutes = 3:25 PM

The Marriott Hotel charges $150 per night for a family
suite. They also charge 11% sales tax. How much
would you pay, including tax, for a 2 night stay in the
hotel?
Answer:
For two night in the hotel, you would pay $333 (including tax)
Step-by-step explanation:
Without tax, the price for 2 nights would be $150 times 2. So the price without tax would be....
$150 x 2 = $300
But then we have to be aware of 11% tax so we would multiply the price for two nights by 1.11 and get...
$300 x 1.11 = $333
Answer:
$333
Step-by-step explanation:
150 x 2 = 300
300 x 0.11 = 33
300 + 33 = 333

Find the mean number of merits received by the girls and boys.
Who did better on average?
Answer:
1. Mean merit for girls = 3.08
2. Mean merit for boys = 3.03
3. The girls did better.
Step-by-step explanation:
The following data were obtained from the question:
Marit >>> Girls >>> Boys
0 >>>>>> 5 >>>>>>> 4
1 >>>>>> 6 >>>>>>> 6
2 >>>>>> 11 >>>>>> 11
3 >>>>>> 15 >>>>>> 13
4 >>>>>> 14 >>>>>> 13
5 >>>>>> 13 >>>>>> 9
6 >>>>>> 1 >>>>>>> 2
1. Determination of the mean number of merit for girls.
Summation of merit of girls (ΣMG) = (0×5) + (1×6) + (2×11) + (3×15) + (4×14) + (5×13) + (6×1)
= 0 + 6 + 22 + 45 + 56 + 65 + 6
= 200
Summation of girls (ΣG) = 5 + 6 + 11 + 15 + 14 + 13 + 1
= 65
Mean merit for girls =?
Mean = ΣMG / ΣG
Mean = 200 / 65
Mean merit for girls = 3.08
2. Determination of the mean number of merit for boys.
Summation of merit of boys (ΣMB) = (0×4) + (1×6) + (2×11) + (3×13) + (4×13) + (5×9) + (6×2)
= 0 + 6 + 22 + 39 + 52 + 45 + 12
= 176
Summation of boys (ΣB) = 4 + 6 + 11 + 13 + 13 + 9 + 2
= 58
Mean merit for boys =?
Mean = ΣMB / ΣB
Mean = 176 / 58
Mean merit for boys = 3.03
3. Determination of who did better.
Mean merit for girls = 3.08
Mean merit for boys = 3.03
We can see from the data above that the mean merit for girls (i.e 3.08) is greater than that of boys (i.e 3.03). Therefore, the girls did better than the boys
