PLEASE HELP ASAP WITH IREADY AREA TYY The circle has a radius of 9 inches and is divided into 6 equal parts. the area of a single section of the circle is equal to 13.5(pie) square inches
The expressions that can be used to find the area of the shaded portion of the circle are 9²·π - (2 · 13.5π ) and 2/3 · 9²·π
How to determine which expressions can be used to find the area of the shaded portion of the circle?Since the whole circle has a radius of 9 inches. The area of the whole circle will be 9²·π square inches (Remember: Area of circle = πr²)
Also, the area of a single section of the circle is equal to 13.5π square inches.
We can get the area of the shaded portion (blue ones) by subtracting the area of the unshaded portion (white ones) from the area of the whole circle. That is:
9²·π - (2 * 13.5π )
Notice that we have 2 unshaded (whites)
Also, there 4 shaded portions out of the whole 6. We can write:
area of shaded portions = 4/6 · 9²·π = 2/3 · 9²·π
Thus, the expressions are is 9²·π - (2 · 13.5π ) and 2/3 · 9²·π

The equation can be used to solve for x is 90-52 = (12x - 10)°
How to determine which equation can be used to solve for x?Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.
In the diagram, since vertically opposite angles are equal. Thus, we can say:
∠UTW = ∠VTZ
90 - 52 = (12x - 10)°
38 = 12x - 10
12x = 38 + 10
12x = 48
x = 48/12
x = 4
Therefore, the equation is 90-52 = (12x-10)°

9 miles for every 1/2 hour and 6 miles for every 20 minutes tell whether the missing values are equivalent and justify
9 miles for every ½ hour and 6 miles for every 20 minutes can be considered equivalent because they represent the same speed, just measured in different units.
To see this, we can convert the units to a common unit, such as miles per hour.
First, let's convert the 6 miles in 20 minutes to miles per hour:
[tex] \frac{6}{20} \times 60[/tex]= 18 miles/hour
Next, let's compare this speed to the 9 miles per ½ hour:
[tex] \frac{9}{ \frac{1}{2} } = \frac{9}{ \frac{1}{2} } \times \frac{1}{ \frac{1}{2} } = 18[/tex]
Since both speeds are equal to 18 miles per hour, we can conclude that they are equivalent. This means that the missing values are also equivalent.

The dimensions of the rectangular field are given as follows:
Length: 232 yards.Width: 59 yards.How to obtain the perimeter of a rectangle?The perimeter of a rectangle is given by twice the sum of the length and the width of the rectangle, as follows:
P = 2(l + w).
For this problem, the perimeter is of 582 yards, hence:
2(l + w) = 582
l + w = 291.
The length of the field is 4 yards less than quadruple the width, hence:
l = 4w - 4.
Then the width is obtained as follows:
4w - 4 + w = 295

Evaluating the piecewise function we will get:
f(-1) = -13
f(0) =-8
f(2) = 10
How to evaluate the piecewise function?Here we have a piecewise function and we want to evaluate it on different values of x.
When x = -1, we need to use the first part, because -1 < 0.
f(-1) = 9*-1 - 4 = -13
when x = 0, we need to use the second part, because 0 ≥ 0.
f(0) = 9*0 - 8 = -8
When x = 2 we also use the second part:
f(2) = 9*2 - 8
f(2) = 18 - 8 = 10

A large equilateral triangle pyramid stands in front of the city's cultural center. Each side of the base measures 50 feet and the slant height of each lateral side of the pyramid is 40 feet.
A painter can paint 100 square feet of the pyramid in 18 minutes.
How long does it take the painter to paint 75% of the pyramid?
Enter your answer, rounded to the nearest tenth, in the box.
Answer:
Step-by-step explanation:
The lateral surface area of the pyramid can be found using the formula for the area of an equilateral triangle:
A = (s^2 * √3) / 4
where s is the length of one side of the equilateral triangle base.
For this pyramid, s = 50 feet
A = (50^2 * √3) / 4 = (2500 * √3) / 4 = 1250 * √3 ≈ 2129.28 ft^2
The total surface area of the pyramid can be found by adding the area of the base to the area of the lateral surface:
A = base area + lateral surface area
A = (side length^2 * √3) / 4 + (3 * triangle area)
A = (50^2 * √3) / 4 + (3 * (50^2 * √3) / 4)
A = 2500 * √3 + 3750 * √3 ≈ 5884.28 ft^2
To paint 75% of the pyramid, the painter needs to paint 75% * 5884.28 ft^2 = 4413.71 ft^2
Since the painter can paint 100 ft^2 in 18 minutes, he can paint 4413.71 ft^2 in 4413.71 / 100 * 18 minutes ≈ 786.96667 minutes
Rounding to the nearest tenth, the painter will take 786.967 minutes to paint 75% of the pyramid, which is approximately 13.1 hours.
7. A rancher has 1000 m of fencing to enclose two rectangular corrals. The corrals have the same dimensions and one side in common. What dimensions will maximize the enclosed area? X y
The dimensions that will maximize the enclosed area are 125 meters by 250 meters
What dimensions will maximize the enclosed area?Represent the dimensions with x and y
So, we have the following equations
Perimeter = 4x + 2y = 1000
Area = 2xy
So, we have
2x + y = 500
This gives
y = 500 - 2x
So, we have
Area = 2x(500 - 2x)
Expand
Area = 1000x - 4x^2
Differentiate and set to 0
1000 - 8x = 0
So, we have
8x = 1000
Divide
x = 125
Recall that
y = 500 - 2x
y = 500 - 2 * 125
y = 250
Hence, the dimension is 125 by 250

Step-by-step explanation:
Doing some calculations, 1 doll costs three dollars and 1 purse costs six dollars.
5 x 3 + 6 = 21
7 x 3 + 1 = 27
If Polly buys 2 dolls and 3 purses, that means she spends six dollars on the dolls and eighteen dollars on the purses.
