Find and simplify an expression for the area of three rows of m squares with side lengths of m centimeters. Please help
The expression for the area of three rows of m squares with side lengths of m centimeters is [tex]3m^3[/tex] square centimeters.
To find the area of three rows of m squares with side lengths of m centimeters, determine the total number of squares.
Each row consists of m squares, and there are three rows in total. Therefore, the total number of squares is 3m.
The area of each square is given by the formula
[tex]A = s^2[/tex],
where s is the length of the side.
Multiply the area of one square by the total number of squares:
Area = (Area of one square) (Total number of squares)
Area = [tex]m^2[/tex] * 3m
Area = [tex]3m^3[/tex]
Therefore, the expression for the area is [tex]3m^3[/tex] square centimeters.

The simplified expression for the area of three rows of m squares with side lengths of m centimeters is 3 * m^3 square centimeters.
To find the area of three rows of m squares with side lengths of m centimeters, we need to determine the total area covered by the squares.
Each row consists of m squares, and each square has a side length of m centimeters. Therefore, the length of each row is m * m = m^2 centimeters.
Since there are three rows, the total length covered by the rows is 3 * m^2 centimeters.
To find the area, we need to multiply the total length by the width, which is also m centimeters. Thus, the area of the three rows of squares is:
Area = Length * Width
Area = (3 * m^2) * m
Area = 3 * m^3 square centimeters

A farmer has chickens and pigs on a farm. The farmer counted 22 heads and 56 feet on all the animals. How many chickens and pigs does the farmer have?
Answer: 16 chickens, 6 Pigs
Step-by-step explanation:
Given
Toal heads=22
Total feet=56
Suppose there are x chickens and y pigs
each animal possess a single head
[tex]\therefore\ x+y=22\quad \ldots(i)[/tex]
Chicken has 2 legs and pig has 4 legs
So, [tex]2x+4y=56\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
x=16 and y=6
So, farmer has 16 chickens and 6 pigs
Tatyana earns $825 per week, but a Social Security tax of 7.51% and a State
Disability Insurance of 1.2% are deducted from her earnings. Assuming no other
deductions, how many dollars does Tatyana take home each week?
Answer:
$753.14
Step-by-step explanation:
7.51% + 1.2% = 8.71%
8.71% off of $825 is $753.14
Answer:
$753.1425 or $753.14
Step-by-step explanation:
7.51% of $825 is $61.96 (You do this by taking the original of $825 and multiplying it by the decimal .0751 (which is the decimal form of 7.51%)
And 1.2% of $825 is $9.9 (Same formula from above, but multiply by .012)

A building casts a shadow 46 feet long. At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long. what is the height of the building
Given :
A building casts a shadow 46 feet long.
At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long.
To Find :
The height of the building.
Solution :
Since, all readings are taken in same time.
Ratio of height and shadow remains for all objects.
Let, height of building is H.
So,
[tex]\dfrac{H}{46}=\dfrac{36}{9.2}\\\\H = \dfrac{36}{9.2}\times 46\\\\H = 180\ feet[/tex]
Therefore, height of the building is 180 feet.

I keep getting this question wrong
Answer: see below
Step-by-step explanation:
Set up two equations, one for each scenario
88w + 21b = 5840
84w + 82b = 9044
Use one equation and isolate one of the variables. We'll isolate w in the first equation.
88w + 21b = 5840
88w = 5840 - 21b
w = (5840 - 21b)/88
Then substitute that into the second equation.
84w + 82b = 9044
42w + 41b = 4522 (simplified)
42((5840 - 21b)/88) + 41b = 4522
21((5840 - 21b)/44) + 41b = 4522 (simplified)
(122640 - 441b)/44 + 1804b/44 = 4522
(122640 - 441b + 1804b)/44 = 4522
122640 + 1363b = 198968
1363b = 76328
b = 56
Now that we know belts are $56, we can substitute that back into any equation and solve for w.
w = (5840 - 21b)/88
w = (5840 - 21(56))/88
w = (5840 - 1176)/88
w = 4664/88
w = 53
