Mr. Mohr wants to build a rectangular patio using concrete tiles that are 12 square inches. The patio will measure 13.5 feet by 43 feet. What is the area of the patio? How many concrete tiles will he need to complete the patio?
Answer: He will need 49 tiles.
Step-by-step explanation:
Given: The patio will measure 13.5 feet by 43 feet.
Area of patio = 13.5 feet x 43 feet [Area = length x width]
= 580.5 sq. feet
Since area of each concrete tile = 12 sq. inch
Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)
= 580.5 ÷ 12
= 48.375 sq. inch ≈49
Hence, he will need 49 tiles.
Answer:
49 tiles
Step-by-step explanation:
Answer: He will need 49 tiles.
Step-by-step explanation:
Given: The patio will measure 13.5 feet by 43 feet.
Area of patio = 13.5 feet x 43 feet [Area = length x width]
= 580.5 sq. feet
Since area of each concrete tile = 12 sq. inch
Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)
= 580.5 ÷ 12
= 48.375 sq. inch ≈49
Hence, he will need 49 tiles.

The system of inequalities represents the given scenario are w ≤ l – 10 and 2l + 2w > 62Therefore, option D is the correct answer.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Given that, the perimeter of a rectangular pool is more than 62 meters.
Let the length of a rectangular pool be l.
The width is at least 10 meters less than the length.
w≤ l-10
So, 2(l+w)>62
2l+2w≥62
Therefore, option D is the correct answer.

What is the solution to the equation 13.7y – 10.6 = 6.2y + 19.4
Answer: hope this helps :)))
y=4
Step-by-step explanation:
Step 1: Subtract 6.2y from both sides.
13.7y−10.6−6.2y=6.2y+19.4−6.2y
7.5y−10.6=19.4
Step 2: Add 10.6 to both sides.
7.5y−10.6+10.6=19.4+10.6
7.5y=30
Step 3: Divide both sides by 7.5.
7.5y/7.5 = 30/7.5
y=4

Clifford works 40 hours per week while working as a laboratory technician. He earns $653.60 for each week of work. How much does he earn in an hour? How much money does he make in 4 weeks?
Answer:
Total income= $2,614.4
Step-by-step explanation:
Giving the following information:
Workweek hours= 40
Total salary per week= $653.6
First, we need to calculate the monetary value of an hour:
Earn per hour= total salary/number of hours
Earn per hour= 653.6 / 40
Earn per hour= $16.34
Now, the total income for 4 weeks:
Total income= 653.6*4
Total income= $2,614.4
can you please explain slope, the y-intercept, how to find the equation and how to graph it properly?
Answer:
Slope is a line on a graph, you find slope with the m=yx+b equation. Y intercept is the point that the line crosses the y axis at, it is represented by b. X and Y in the equation are your coordinates. You graph it by starting at your y-intercept and going up in a straight line following the slope calculated.

Ruby misses 10% of the free throws she attempts in a season. How many total free throws did she attempt if she missed 70?
Answer:
700
Step-by-step explanation:
70x10 = 700
The total number of free throws she attempted is 700.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Missed free throws = 10%
Total free throws = 100%
10% = 70
Multiply 10 on both sides.
100% = 700
Thus,
Total free throws are 700.

Step-by-step explanation:
If x^2+x =3^2/3+3^-2/3 then prove that 3x^3+9x-8=0
x^2 + 2 = 3^2/3 + 3^-2/3
x^2 = 3^2/3 + 3^-2/3 - 2
x = √(3^2/3 + 3^-2/3 - 2)
x = 0.748888296
Substitute for x in 3x^3 + 9x - 8:
3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.
So it is proved.

Help I'm being timed I don't understand how to do this at all and I would need and example I need to explain how I calulated my answer
Answer:
Look at the numerators, how do you change 90.6 to 22.65? You divide 90.6, but by what? So, we divide to get the number we divide by, which is 4.
90.6 divided by 22.65 = 4
Now, we do the same to the 12 2/5. Since we divided the top by 4, we'll divide 12 2/5 by 4 as well. Change 12 2/5 to a decimal and then divide to get the denominator of the second number.
12 2/5 divided by 4 = 3.1
So, 90.6/12 2/5 = 22.65/3.1
