A scale model of a merry-go-round and the actual merry-go-round are similar.
a. How many times greater is the base area of the actual merry-go-round than the base area of the scale model? Explain. The ratio of the corresponding lengths is : 1. So, the ratio of the areas is : 1 and the base area of the actual merry-go-round is times greater than the base area of the scale model.
b. What is the base area of the actual merry-go-round in square feet? The base area of the actual merry-go-round is square feet.
The base area of the actual merry-go-round is the same as the model due to the 1:1 scale. Without further information, the actual base area of the merry-go round cannot be calculated.
Explanation:To understand this, we need to know a key principle of scale models. In a scale model, when the ratio of the lengths is 1:n, the ratio of the areas is square of that, or 1:n2. Hence, if the scale of models is 1:1 as given, the base area of the actual merry-go-round is equal to the base area of the scale model, meaning the ratio is also 1:1.
For part b, without the specific measurements of the base area of the scale model or the scale used, it is impossible to calculate the base area of the actual merry-go-round in square feet. We need one or the other to make this calculation.

The base area of the actual merry-go-round is 16 times greater than the base area of the scale model. The base area of the actual merry-go-round in square feet can be calculated using the base area of the scale model.
Explanation:The base area of the actual merry-go-round is 16 times greater than the base area of the scale model. This is because the ratio of the corresponding lengths is 1:4, so the ratio of the areas is 1:16.
To find the base area of the actual merry-go-round in square feet, you will need to know the base area of the scale model in square feet. If you provide the base area of the scale model, I can help you calculate the base area of the actual merry-go-round.

What is the area of the kitchen floor in this floor plan?
A-24 sq meters
B-28 sq meters
C-35 sq meters
D-42 sq meters
Answer: The correct option is (C) 35 sq. meters.
Step-by-step explanation: We are given to find the area of the kitchen floor in the floor plan shown in the figure.
From the figure, we see that
the kitchen is in the form of a rectangle with length 7 meters and breadth 5 meters.
We know that
the area of a rectangle with length l units and breadth b units is given by
[tex]A=l\times b.[/tex]
For the rectangular kitchen, we have
length, l = 7 meters
and
breadth, b = 5 meters.
Therefore, the area of the kitchen floor in the floor plan is given by
[tex]A=l\times b=7\times 5=35~\textup{sq. meters}.[/tex]
Thus, option (C) is CORRECT.
Simplify (x3+ 8x + 5) − (2x2− 3x − 12). −x2+ 11x + 17 x3− 2x2+ 11x + 17 −x2+ 5x − 7 x3− 2x2+ 5x − 7
what is f(-5) if f(x) equals |2x-1|+10?
Answer:
The value of the function for f(-5) is 21.
Step-by-step explanation:
Consider the provided function.
[tex]f(x)=|2x-1|+10[/tex]
We need to find the value of the function for f(-5).
Substitute the value of x=-5 in the above function.
[tex]f(-5)=|2(-5)-1|+10[/tex]
[tex]f(-5)=|-10-1|+10[/tex]
[tex]f(-5)=|-11|+10[/tex]
The absolute value of -11 is 11.
[tex]f(-5)=11+10[/tex]
[tex]f(-5)=21[/tex]
Hence, the value of the function for f(-5) is 21.

Multiply or divide as indicated 10x^5/2x^2
The expression [tex]10x^5/2x^2[/tex] simplifies to [tex]5x^3[/tex] by dividing the coefficients (10/2) to get 5 and subtracting the exponents (5 - 2) in [tex]x^5[/tex] and[tex]x^2[/tex]to get 3.
Explanation:To solve the given expression, [tex]10x^5/2x^2[/tex], you would first divide the coefficients and then deal with the bases (x) separately.
The coefficients (numbers without variables), 10 and 2, divide to give you: 10/2 = 5.
For the part that includes x, [tex]x^5/x^2[/tex], you subtract the lower exponent from the higher exponent because when you divide powers with the same base you subtract the exponents. So 5 - 2 = 3.
Thus, the final answer is: [tex]5x^3[/tex].

Martin drew a pair of perpendicular lines and a pair of parallel lines.which of these statements best compares the pairs of perpendicular and parallel lines?
The transitive property of equality states that:
if a = b, then b = a
if a = b, then ac = bc
if a = b and b = c, then a = c
if a = b and c = c, then a + b = b + c
Answer: The correct option is
(C) if a = b and b = c, then a = c.
Step-by-step explanation: We are given to select the correct statement for the transitive property of equality.
We know that
if x, y and z are three real numbers, then the transitive property of equality states that
if x = y and y = z, then x = z.
So, for reals a, b and c, the property states that
if a = b and b = c, then a = c.
Option (C) is CORRECT.

Mayumi is constructing a line through point P that is perpendicular to RS←→. A horizontal line segment R S and a point P are drawn. The point P is above the horizontal line segment R S. She places her compass on point P to construct an arc. What must be true about the width of the compass opening when Mayumi draws the arc? It must be greater than 12RS. It must be equal to PS . It must be wide enough so that the arc intersects RS←→ in two points. It must be equal to PR .
Width of the compass should be more than the smallest space between P and RS, so that it cuts RS at two distinct points. Therefore, it must be wide enough so that the arc intersects RS←→ in two points. The photo is attached so that you can understand it more.
