Perimeter = 2W + 2L
134 = 2(29) + 2x
134 - 58 = 2x
x = 76/2
x = 38 (length)
A = 2L + 2(29) >= 134 (more or equal = >=)

robby raises holstein and jersey cows on his farm in the ratio of 7:5 if he has a total of 48 cows on his farm how many holstein cows does he own?
Answer:
28
Step-by-step explanation:
The total amount of cows is 48 and is split into 12 groups (7+5).
So 1 group is 48÷12=4
1 group=4
He owns 7 groups of Holstein cows.
So if 1 group is 4, 7 groups is 7x4=28.
28
The number of Holstein cows, if The ratio of Holstein and jersey cows is 7:5, and the Total number of cows is 48, is 28.
What is ratio?It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3. If b is not equal to 0, an ordered pair of numbers a and b, denoted as a / b, is a ratio. A proportion is an equation that equalizes two ratios.
Given:
The ratio of Holstein and jersey cows is 7:5,
Total number of cows = 48
Calculate the values as shown below,
Assume the number of Holstein cows is 7x
7x + 5x = 48
12x = 48
x = 4
Thus, the number of Holstein cows is 7 × 4 = 28

and 4-2” wide?
The area of the rectangle will be 4350 Inches squared.
What is the area of the rectangle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that a rectangular floor is 7-3" long and 4-2” wide. Here 7 ft 3 in = 87 in. 4ft 2 in = 50 in.
The area of the rectangle is calculated by using the formula below:-
Area = Length x Width
Area = 87 x 50
Area = 4350 Inches
Therefore, the area of the rectangle will be 4350 Inches squared.

Damien washes cars on his summer vacation to earn money. It took him 16 hours to wash 10 cars. Use scaling to complete the table to determine the number of cars Damien could wash in 40 hours, is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of cars that were washed in 40 hours be x,
Now, according to the question.
16 / 10 = 40 / x
x = 400 / 16
x = 25
Thus, the required number of cars that can be washed by Damien in 40 hours is 25.

Find the value of f(3) y=f(x)
9514 1404 393
Answer:
-4
Step-by-step explanation:
On a graph like this where not every grid line is marked with its value, you have to determine the spacing of the grid lines by noting how many are between the values shown. Here, the vertical grid lines are marked on the x-axis with even numbers on every other line. That means the lines not numbered have a value halfway between the values on the lines that are numbered.
The grid line for x = -3 is the one halfway between the grid lines for -2 and -4. Following that line down to where it intersects the function graph, we find the y-coordinate of that (vertex) point to be -4. (It is on a marked horizontal grid line, so you can read the value from the axis scale.)
The value of f(-3) is -4.

Answer:
1 5/24 + 7 22/24 = 8 27/24
Step-by-step explanation:
No change is required to the fraction on the first line:
1 5/24 = 1 5/24
The fraction on the second line can be multiplied by 2/2 to make its denominator 24.
7 11/12 = 7 22/24
The fraction on the third line is the sum of the fractions on the other two lines. It is an improper fraction. We know this because the integer portion of the sum is shown as 8, not 9, as it would be if the fraction were reduced.
5/24 +22/24 = 27/24
Then the sum is ...
1 5/24 +7 22/24 = 8 27/24
_____
If the fraction on the final line were reduced, the sum would be 9 3/24 = 9 1/8.
