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
2(6x + 3) = 18 - 3(16 - 3x)
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

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.

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
. Seven cards are numbered from 1 to 7 and placed in a box. One card is selected at random, then replaced. Another
card is randomly selected. What is the probability of selecting two odd numbers?
Answer:
Im not sure, but I can give advice!
Step-by-step explanation:
Study and wach yt vids (: hope I helped a bit!
Answer:
25/59
Step-by-step explanation:
Since there are 5 odd cards and 7 cards total, the probabilty of drawing an odd card is 5/7.
he probability of two events happening is the probability of each multiplied together, so multiply 5/7 by 5/7 to get 25/49.

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.

Step-by-step explanation:
Answer:
D) 23.5
Step-by-step explanation:
First solve for x² + y³, which inserting the numbers would be 4² + 5³. This is also 16 + 125 or 141. Now solve for the bottom: 2 + x or 2 + 4 to get 6. Divide 141/6 to get 23.5.

State the postulate or theorem you would use to prove each pair of triangles congruent. If the triangles cannot be proved congruent, pick not possible
The triangles can be proven similar by the congruent theorem of triangles
What are Congruent Triangles?
Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the two triangles be ABC and DEF
Now , the two triangles will be similar if
The three sides are equal
So , AB = BC = CD and
DE = EF = FD
And the two triangles are congruent if
By ASA theorem - two angles are the same and a corresponding side is the same
And ,
By SAS theorem : Two sides are equal and the angle between the two sides is equal
And ,
By RHS theorem : A right angle, the hypotenuse and a corresponding side are equal
Hence , the triangles ABC and DEF is similar ΔABC ≅ ΔDEF

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.

Manny grows vegetables in a community garden.
His part of the garden is a rectangular area that is 6 yards long and 5 1/3 yards wide. What is the area of Manny’s garden? Be sure to include units in your answer.
Answer:
32 yards (squared)
Step-by-step explanation:
Length x width = area (LxW=A)
Step 1:
Length = 6 yards
Width = 5 1/3 yards
Step 2:
Multiply 6 x 5 1/3 because 6 is the length, 5 1/3 is the width, and LxW=A.
6 x 5 1/3 = 32 yards (squared)
