The pair of figures is similar. Find x. Round to the nearest tenth if necessary.
A. 34 cm
B. 9.8 cm
C. 21.9 cm
D. 29.6 cm
Answer:
Choice B
Step-by-step explanation:
When two shapes are similar their sides are always going to be proportional. So here we will set up a proportion to solve this.
[tex]\frac{23}{40}=\frac{x}{17}[/tex]
Now we cross multiply
[tex]391=40x[/tex]
After we got an equation we solve it
[tex]x=9.775[/tex]
Since we got a decimal we will have to round it to the place they instruct for us, on this one it is 9.8 cm so it is choice b.
The required value of x is 9.8 cm. For the two similar triangles.
Two similar triangles are given. value of x to be determined.
Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Here, if triangles are similar then their ratio of sides is also equal.
x/23=17/40
x = 0.425*23
x = 0.425 * 23
x = 9.8 cm
Thus, The required value of x is 9.8 cm. For the two similar triangles.

Answer:
question 1 is 22
question 2 is 122
ask your teacher why u got question 1 wrong
Step-by-step explanation:
90-68 is 22
180-58= 122
Answer:
1. 22 degrees
2. 122 degrees
3. Angle 1 is supplementary to angle 6
Step-by-step explanation:
1. It is supposed to be a right angle which means that 90. So, to find GHK you must do 90 - 68 = 22. I don't understand why it is incorrect but, I can promise you that is the correct answer
2. A straight angle is 180 degrees. So, you would subtract 180 - 58 = 122.
Therefore, your answer for 2 would not be 112 degrees it would in fact be 122 degrees.

A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours
Answer:
We can write proportion as:
[tex]\frac{\mathbf{30\:miles}}{1.5\:hours}=\mathbf{\frac{x\:miles}{4\:hours}}[/tex]
Step-by-step explanation:
A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours
Proportion:
A proportion is used when two ratios are equal. It can be written as a/b=c/d
In our case we have:
a= 30 miles
b = 1.5 hours
c = x miles
d = 4 hours
We can write proportion as:
[tex]\frac{\mathbf{30\:miles}}{1.5\:hours}=\mathbf{\frac{x\:miles}{4\:hours}}[/tex]

The scatter plot shows the relationship between pages read per week and age. What is the domain of the cluster shown in the scatter plot?
A) 8 to 10 years of age
B) 8 to 17 years of age
C) 32 to 39 pages read per week
D) 32 to 72 pages read per week
Answer:
part 1 of the question is d ,and part 2 of the question is b.
The range of the cluster shown in the scatter plot is 32 to 72 pages read per week.
Option D is the correct answer.
The domain of the cluster shown in the scatter plot is 8 to 17 years.
Option B is the correct answer.
What is a scatterplot?A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.
In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.
The position of each point on the graph represents the values of both variables for that particular observation.
We have,
The range in the scatterplot is the number of pages read per week.
Now,
The plot in the scatter plot is between 32 to 72 pages.
So,
The range of the cluster shown in the scatter plot is 32 to 72 pages read per week.
And,
The domain in the scatterplot is the number of ages in years.
Now,
The plot in the scatter plot is between 8 to 17 years.
So,
The domain of the cluster shown in the scatter plot is 8 to 17 years.
Thus,
The range of the cluster shown in the scatter plot is 32 to 72 pages read per week.
The domain of the cluster shown in the scatter plot is 8 to 17 years.

Answer:
d = 18.02 m
Step-by-step explanation:
Given that,
A rectangular lawn has a diagonal path running across it. The lawn is 10m wide and 15m long.
We need to find the length of the path.
The diagonal of a rectangle can be calculated as follows :
[tex]d=\sqrt{10^2+15^2} \\\\d=18.02\ m[/tex]
So, the length of the path is 18.02 m.
Carrie received 42% of the vote for Treasurer of her school's Latin Club. If there are 67 students, how many students voted for her?
Answer:
28 people voted for Carrie
Step-by-step explanation:
Make the 42% a decimal, and multiply the decimal by 67.
You can make a decimal by moving the number back two digit places
and removing the percent sign, to get .42; you then multiply the two numbers together.
The number of students who voted for her will be 27.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Carrie received 42% of the vote for Treasurer of her school's Latin Club.
The number of votes received by Carrie will be calculated as:-
Number = 67 x 42%
Number = 67 x 0.42
Number = 27
Hence, the number of votes will be 27.

Answer:
Step-by-step explanation:
As given
we have 50 kg oranges at the rate of 80 per kg and also she paid Rs. 5 per kg as fare , and sold totally by price of Rs. 4675
Now first we have to know that how much money she spent ,
1 kg = Rs. 80
50 kg = Rs. x
by cross multiplication ,we get
x= 80*50
x= Rs. 4000 total cost of oranges
Now total cost of fare,
1kg = Rs 5 fare
50 kg = y
we get , by cross multiplication,
y=Rs.250
Now total cost = x+ y = 4000+250 = Rs. 4250
As she sold it with price of Rs 4675
hence ,the profit she made ,
Profit = 4675-4250 = Rs.425
