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

Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?
Answer:
6x - 5 ≥ 8
Step-by-step explanation:
Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?
The inequality sign of
a) At least = greater than or equal to = ≥
Let us represent the number as = x
Hence: "five less than the product of a number and 6 is at least 8" can be written as:
= x × 6 - 5 ≥ 8
= 6x - 5 ≥ 8

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

Answer:
i = the square root of -1
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Given
[tex]\frac{2-i}{2+i}[/tex]
Multiply the numerator/ denominator by the conjugate of the denominator.
The conjugate of 2 + i is 2 - i , then
= [tex]\frac{(2-i)(2-i)}{(2+i)(2-i)}[/tex] ← expand numerator/ denominator using FOIL
= [tex]\frac{4-4i+i^2}{4-i^2}[/tex] [ i = [tex]\sqrt{-1}[/tex] ⇒ i² = - 1 ]
= [tex]\frac{4-4i-1}{4+1}[/tex]

The school that Imani goes to is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 3 senior citizen tickets and 3 child tickets for a total of $69. The school took in $91 on the second day by selling 5 senior citizen tickets and 3 child tickets. What is the price each of one senior citizen ticket and one child ticket?
Answer:
Cost of one senior citizen ticket = $11
Cost of one child ticket = $12
Step-by-step explanation:
Let,
x be the cost of one senior citizen ticket
y be the cost of one child ticket
According to given statement;
3x + 3y = 69 Eqn 1
5x + 3y = 91 Eqn 2
Subtracting Eqn 1 from Eqn 2
(5x+3y)-(3x+3y) = 91 - 69
5x+3y-3x-3y = 22
2x = 22
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{22}{2}[/tex]
x = 11
Putting x = 11 in Eqn 1
3(11) + 3y = 69
33 + 3y = 69
3y = 69 - 33
3y = 36
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{36}{3}\\y=12[/tex]
Hence,
Cost of one senior citizen ticket = $11
Cost of one child ticket = $12
help me pleaseeeeeeeeee
Answer:
D
Step-by-step explanation:
If the cost is the y-axis (said in question) it would be narrowed down to B and D. But since the rate of change is constant and will be the same, the line would be countinuous making D be the right answer.
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
Soo $333 I believe?

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

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
