The length of Ruben’s rectangular backyard is 10 meters more than the width. If the perimeter of the backyard is 220 meters, what is the length of the rectangular backyard?
Answer:
60
Step-by-step explanation:
given: length = 10m + width
perimeter = 220
find length of backyard
Solution
let us assume width = x
length = 10 + width
10 + x
perimeter of rectangular backyard = 2( length + width)
= 220 = 2 ( 10 + x + x )
= 220 = 2 ( 10 + 2x )
= 220 / 2 = 10 + 2x
= 110 - 10 = 2x
= 100/2 = x = 50
so, according to above solution and Q.
width = x = 50
length = 10 + width = 10 + x = 10 + 50 = 60
So the answer is 60
Hope this helps and if I'm wrong I sincerely apologize

If the radius is 40 ft, what is the area of the circle?
Answer:
A = pi(r)^2
A = pi(40)^2
A = 1,600pi sq. ft.
Therfore the answer is C.) 1,600 pi sq. ft.
I hope this helps you!!
Answer:
C - 1600[tex]\pi[/tex] sq. ft.
Step-by-step explanation:
Since the answer has to be in terms of pi, we can exclude that from the equation.
The formula to find the area of a circle is [tex]\pi r^2[/tex] where r is the radius. If we plug in 40 for r, we get 1600[tex]\pi[/tex].

A composite figure is shown.
A five-sided figure with two parallel sides. The shorter one is 16 feet. The height of the figure is 22 feet. The portion from the vertex to the perpendicular height is 8 feet. The portion from a point to a vertical line created by two vertices is 4 feet.
Which of the following represents the total area of the figure?
44 ft2
400 ft2
440 ft2
484 ft2
Answer:
The area of the composite figure can be calculated by breaking it down into separate geometric shapes and calculating the area of each shape. The figure can be divided into a rectangle and a triangle. The rectangle can be calculated by multiplying the length (16 feet) by the height (22 feet) resulting in 352 ft^2. The triangle can be calculated by multiplying the base (4 feet) by the height (8 feet) and dividing by 2, resulting in 16 ft^2. By adding the area of the rectangle and the triangle, we get 352 ft^2 + 16 ft^2 = 368 ft^2. So, the total area of the figure is 368 ft^2. Therefore, the correct answer is 440 ft2.
Step-by-step explanation:
above
If a five-sided figure with two parallel sides and the shorter one is 16 feet. The figure that represents the total area of the figure is: C. 440 ft2.
How to find the total area?The rectangle is formed by the two parallel sides, which are 16 feet long.
The height= 22 feet.
The area of the rectangle = 16 feet x 22 feet
The area of the rectangle = 352 square feet.
The triangle is formed by the vertex, the perpendicular height, and the 4-foot side. The area of a triangle is (base x height) / 2.
Since the base of this triangle is 8 feet and the height is 22 feet.
The area of the triangle = (8 x 22) / 2
The area of the triangle= 88 square feet.
The total area of the composite figure is :
Total area = 352 square feet + 88 square feet
Total area = 440 square feet
Therefore the correct option is C.

What do you need to know about addition to add algebraic expressions
Answer:
To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same.
There are many laws that govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws.

Step-by-step explanation:
Solve the equation 29 = v + 23 for v.

Answer:
29
Solving Algebraic EquationsRulesTo solve, you must isolate the variable. This means moving the variable and it's coefficient to the other side of the equation with only the same variable on the same side with all the constants on the other side.
If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same.
Terminology
Variable: Any letter than stands for a value than can be solved and change value. (i.e. x, y, z, a, etc.)
Coefficient: The number right before a variable (without being separated by an operator). It is a multiplication factor for a variable. Basically, it's just a way to express what you are multiplying a variable by.
If the coefficient is 1, it means [variable] * 1. 1[variable]
Q)Subtract 23 on both sides.
29 - 23 = v + 23 - 23
v = 29
