Area = length x width.
Divide the two total areas by the width to find the lengths:
760/16 = 47.5
1000/16 = 62.5
The interval is:
47.5<= x <= 6.5
The interval for the length of x that you will cover before you need to buy more roof coating will be 47.5 ≤ x ≤ 6.5.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.The space occupied by any two-dimensional figure in a plane is called the area.
Given that you have 20 gallons of roof coating to apply to the roof of a mobile home that is 16 feet wide. Twenty gallons covers 760 to 1000 square feet.
The formula to calculate the area of the
Area = length x width.
Divide the two total areas by the width to find the lengths:
760/16 = 47.5
1000/16 = 62.5
The interval is:
47.5 ≤ x ≤ 6.5
Therefore, the interval will be 47.5 ≤ x ≤ 6.5.

The Johnson family is going to build a new home. They need to have working drawings of their house plans created by a design firm. They will choose between Rock the House Digital Designs and Elegant Home Architects. Rock the House Digital Designs charges $500.00 for the initial consultation with the Johnson family, plus $50.00 for every additional hour of work for the house plans. Elegant Home Architects charge $75.00 per hour for the house plans. Let ℎ represent the number of hours for which the Johnson family hires the design firm. Which of the following statements are true? Select all that apply.
Answer:
B.The expression 75ℎ represents the total charge for Elegance Home Architects.
D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Step-by-step explanation:
Which of the following statements are true? Select all that apply.
A.The expression 50ℎ represents the total charge for Rock the House Digital Designs.
B.The expression 75ℎ represents the total charge for Elegance Home Architects.
C.The cost for using Rock the House Digital Designs for an initial consultation only is $550.
D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Answer:
Rock the House Digital Designs charges $500.00 for the initial consultation with the Johnson family, plus $50.00 for every additional hour of work for the house plans. If they are hired for h hours, the total charge for Rock the House Digital Designs would be:
Total charge for Rock the House Digital Designs = 500 + 50h
Elegant Home Architects charge $75.00 per hour for the house plans, if they work for h hours, the total charge would be:
Total charge for Elegance Home Architects = 75h
A) Option A is not correct since the total charge for Rock the House Digital Designs is 500 + 50h
B) Option B is correct because the total charge for Elegance Home Architects = 75h
C) Option C is not correct, For an initial consultation, the cost for using Rock the House Digital Designs is $500
D) For a period of 15 hours:
Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(15) = $1250
Total charge for Elegance Home Architects = 75h = 75(15) = $1125
Option D is correct because Elegance home architect would be cheaper
E) For a period of 40 hours:
Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(40) = $2500
Total charge for Elegance Home Architects = 75h = 75(40) = $3000
Option D is correct because Rock the House Digital Designs would be cheaper

A committee of three students met with the principal today and agreed that Rachel will report to the principal every $9$ days, Jessica every $12$ days, and Richard every $15$ days. What is the least number of days before all three will again report to the principal on the same day?
Answer:
180 days
Step-by-step explanation:
To solve for the least number of days all three will again be report to the principal, find the lowest common multiples of all three of them
Rachel will report to the principal every 9 days, Jessica every 12 days, and Richard every 15 days
Rachel (every 9 days) = 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180
Jessica (every 12 days) = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180
Richard (every 15 days) = 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180
The lowest common multiples of 9 days, 12 days, 15 days is 180 days
Therefore, the least number of days all three will report again to the principal is 180 days

the area of square is 36 square meters. what is the length (in meters) of one side in the square
Answer:6m
Step-by-step explanation:
Square root 36m²
The required length of the side of the square is 6 meters.
Given that,
the area of the square is 36 square meters, what is the length (in meters) of one side in the square needs to be determined.
A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,
Examples of the polygon, equilateral triangle, square, pentagon, etc
Here,
Since all the sides of the square are identical and the square is a polygon also.
Area of square = (side)²
we have given the area of a square, i.e. 36
36 = side²
side = √36
side = 6 (since √36 = 6)
Implies length of its side is 6 meters
Thus, the required length of the side of the square is 6 meters.

How are rational numbers and Integers similar? How are they different?
Answer:
Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers. They are different because Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… is a rational number but not an integer. All rational numbers belong to the real numbers. If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites.

Sam made ten to add 7 + 2 + 6 Enter number to complete the equation. Sam first added 7 + 2 = 9. Then he made 10 to find the find the sum. The sum is 4 + 6 = 10 + ? = ?
Answer:
So we have the addition.
7 + 2 + 6.
First, she added the 7 + 2 = 9
So we can replace that in our addition as:
7 + 2 + 6 = (7 + 2) + 6 = 9 + 6
Now, we can use 9 = 5 + 4, and replace that in the addition.
Then we have:
9 + 6 = (5 + 4) + 6
And we know that 4 + 6 = 10.
Then:
5 + 4 + 6 = 5 + (4 + 6) = 5 + 10 = 15.

∠GEF = (5x - 3)°
Find:
value of x
Computation:
∠DEF = ∠DEG + ∠GEF

A football match started by 10.25am and ended by 1.35pm. how long did it last?
Answer:
The match last for 3 hours and 10 minutes.
Step-by-step explanation:
Match started at 10.25 am
Match ended at 1.35 pm
We need to find how long did the match last.
Minutes between 10.25 am to 11 am = 35 minutes
Minutes between 1 pm to 1.35 pm = 35 minutes
Time between 11 am to 1 pm = 2 hours
Time between 10.25 am and 1.35 pm is :
T = 2 hours 70 minutes
But 1 hour = 60 minutes
T = 2 hours (60+10) minutes
T = 3 hours 10 minutes
It means the match last for 3 hours and 10 minutes.
