the community center built a new playground. The sections of the playground are geometric shapes, shown in the picture below
What is the total area of the surface of the entire playground in square feet (use 3.14 for pi)
Answer:
area = 2348 ft^2
Step-by-step explanation:
(15 x 40) + (28x40) + Pi(20^2)(0.5) = area
area = 600 + 1120 + 628 = 2348 ft^2
Answer:
Step-by-step explanation:
So we have a half circle, a rectangle, and a triangle.
circle area is A=3.14r^2 and the radius is 40/2=20, since we only have half a circle
A=3.14(20^2)/2=628ft^2
The rectangle has an area A=LW=28(40)=1120ft^2
The triangle has area A=bh/2=40(15)/2=300ft^2
So the total area is
A=628+1120+300=2048ft^2
The figures are similar. Find x
Answer:
x = 15
Step-by-step explanation:
The scale factor is 8:20, we need to set up a proportion
Setting up the proportion:
[tex] \frac{8}{20} = \frac{6}{x} [/tex]
cross-multiply
8x = 120
x = 15 | Divide both sides by 8

Mike's younger brother likes to ride his bike. If the wheels have a radius of 25 cm, determine how far the wheel travels in 2 revolutions.
Answer:
Intwo full revolutions,the wheel will travel 314 cm
Step-by-step explanation:
Recall that in one full revolution, the wheel will tavel the length of the wheel's circumference, That is:
In each revolution the wheel will cover 2 pi R = 2 * 3.14 * 25 cm = 157 cm
Therefore, in2 full revolutions, the wheel will cover twice this amount:
In 2 revolutions the wheel will travel: 2 * 157 cm = 314 cm.
Answer:

Answer:
The missing side's length is 18.2
Step-by-step explanation: To find a missing side in a right triangle, you use the Pythagorean theorem to solve it. According to the Pythagorean Theorem, [tex]12.6^{2}[/tex] + [tex]13.1^2[/tex] = [tex]x^{2}[/tex], so 158.76 + 171.61 = [tex]x^{2}[/tex] ⇒ 330.37 = [tex]x^{2}[/tex] ⇒ x ≈ 18.2.
1. If AABD - AHGE and AC and HF are angle
bisectors, find x.
B
G
F
24
. م
X
35
E
14
H
Answer:
9.6
Step-by-step explanation:
Find the diagram attached. Using the similarity theorem of triangles
AC/AD = FH/EH
Given
AC = 24
AD = 35
FH = x
EH = 14
Substitute into the formula
24/35 = x/14
Cross multiply
35×x = 24×14
35x = 336
x = 336/35
x = 9.6
Hence the value of x is 9.6

Suppose that 65\ee, percent of the 310{,}000310,000310, comma, 000 citizens in a county are registered to vote. A not-for-profit organization takes an SRS of 100100100 of these citizens and finds that 67\gg, percent of those sampled are registered to vote. The organization plans on taking repeated samples like this. What are the mean and standard deviation of the sampling distribution of the proportion of citizens who are registered to vote
Answer:
mean= 0.65
standard deviation=[tex]\sqrt{\frac{0.65(0.35)}{100}[/tex]
Step-by-step explanation:
The mean of the sampling distribution is 0.65 and the standard deviation is approximately 0.004779.
What is the standard deviation?The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
The mean of the sampling distribution of the proportion of citizens who are registered to vote is equal to the proportion of all citizens who are registered to vote, which is 65% = 0.65.
The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:
standard error = √((65% × 35%) / 100)
= √((0.65 × 0.35) / 100)
= √(0.0227 / 100)
= √(0.0000227)
= 0.004779
Therefore, the standard deviation is approximately 0.004779.

Write the equation. Solve for x.
Answer:
X = 3
Step-by-step explanation:
First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.
5x + 2 = 17
Then Solve For X
5x + 2 = 17
Subtract 2 from both sides
5x = 15
Divide by 5
X = 3
Check your answer
5(3) +2 = 17
15 + 2 = 17
17 = 17
It is correct!

someone please pass the answers to this
Answer/Step-by-step explanation:
1. The figure is composed of a triangle and a rectangle.
Area of the triangle = ½*base*height
base = 4 ft
height = 12 - 8 = 4ft
Area of triangle = ½*4*4 = 8 ft²
Area of rectangle = length * width
Length = 8 ft
Width = 4 ft
Area of rectangle = 8*4 = 32 ft²
✔️Area of the figure = 8 + 32 = 40 ft²
2. The figure is composed of a semicircle and a triangle
Area of the semicircle = ½(πr²)
radius (r) = 3 cm
π = 3
Area = ½(3*3²) = 13.5 cm²
Area of triangle = ½*base*height
base = 3*2 = 6 cm
height = 6 cm
Area = ½*6*6 = 6 cm²
✔️Area of the figure = 13.5 + 6 = 19.5 cm²

Negative 1.75
Negative 2 and one-half
Answer:
The number that is represented by point E is -0.25
Step-by-step explanation:
Point E is between -1 and 0, -0.25 is also between -1 and 0, so the number that is most likely to be represented by point E is -0.25.
