What is the surface area of the figure below? Use 3.14 for Pi.
Answer:
132.52 [tex]cm^{2}[/tex]
Step-by-step explanation:
radius=3
Area of circle= 3.14x3 squared
=28.26
28.26x2=56.52
area of rectangle=76
The surface area of the composite figure will be 136.52 square cm.
What is the area?The area of a two-dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.
The area is a combination of the area of the rectangle and the area of the circle. Then we have
A = L x W + 2 x πr²
The radius, length, and width will be 3 cm, 20 cm, and 4 cm, respectively.
The area is calculated as,
A = 20 x 4 + 2 x 3.14 x 3 x 3
A = 80 + 56.52
A = 136.52 square cm

What is the solution of the following system?
y=-x+2
y=-4x – 1
Your answer
Answer:
y = 3
x = -1
Step-by-step explanation:
The idea to start the problem is that we need to cancel x in one equation to find y first, therefore:
y = -x + 2 (let's multiply this entire equation by -4)
y = -4x - 1
We then have .:
- 4y = 4x - 8
y = -4x - 1 (now we sum both equations)
.:
- 3y = -9 (isolate y)
y = -9 / -3
y = 3 (good we have y!)
Now come back to one of the equations, substitute y to find your x!
Substituting on the first equation we have:
3 = -x +2 (isolate x)
3 - 2 = -x
1 = -x (multiply everything by -1)
x = -1

Step-by-step explanation:
Using the Pythagorean theorem, we can find 1/2 the length of b. We will call it x
15^2 + (x)^2 = 17^2
225 + x^2= 289
Subtract 225 from each side
x^2 = 289-225
x^2 =64
Take the square root of each side
sqrt(x^2) = sqrt(64)
x =8
This is one half the length of b
b= 2*8
b = 16

What is the radius of the circle given by the equation below?
x2 + 12x + y2 - 12y = -56
A. 2
B. 16
C. 4
D. 8
Answer:
C
Step-by-step explanation:
First, you gotta complete the square!
x^2+12x+36 = (x+6)^2
y^2-12y+36 = (y-6)^2
So, we have (x+12)^2 + (y-6)^2 = -56 + 36 + 36
The right side of the equation is the radius^2.
Simplify:
-56 + 36 + 36 = 16
The square root of 16 is 4, so the answer is C!

How will the graph of line y = -3x+8 be affected if the 8 is changed to -3?
A. The y-intercept will be moved 3 units downward.
B. The y-intercept will be moved 5 units downward.
C. The y-intercept will be moved 11 units downward.
D. The x-intercept will be moved 3 units to the left.
E. The x-intercept will be moved 11 units to the left.
Answer:
C
Step-by-step explanation:
A y intercept lies on the y axis.
This means that the movement will happen with the y intercept, on the y axis.
8 is the original y intercept.
It is now changed to -3.
-3 is lower than 8 on the y axis so we are moving downward.
Now, to find the number of squares it moves, we can find the difference between 8 and -3.
8-(-3)=11
Therefore, The y-intercept will be moved 11 units downward.
Answer:
C.
Step-by-step explanation:
The -3x tells you the slope (rise/run). In this case, it will go downward because it is negative. It will have a slope of 3/1. The +8 or -3 is the y intercept and tells which direction the original line will go from its' starting point. So you would add those together to know which way the line moves.

hope this help
If each score in a set of data scores were increased by 8 points:
The mean would increase by 8, and the standard deviation would remain the same.
Option C is the correct answer.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Mean is the sum of all the values divided by the number of the values.
Example:
1, 2, 3, 4, 5
Mean = (1 + 2 + 3 + 4 + 5) / 5
Mean = 15/5 = 3
Now,
If 1 is increased in each set,
Mean = (2 + 3 + 4 + 5 + 6) / 5
Mean = 20/5 = 4
We see that,
3 + 1 = 4
So,
The Mean is increased by the number we add with each number.
Now,
The standard deviation shows how the values are spread so,
Increasing each number will not change the standard deviation.
Thus,
The mean would increase by 8, and the standard deviation would remain the same.

A sports franchise would like to increase their Instagram followers by 25%. This means they would need 300,000
more followers. How many followers do they currently have?
a) 75,000
b) 300,000
c) 525,000
d) 1,200,000
Answer:
D. 1,200,000
Step-by-step explanation:
25%=0.25 which if multiplied by 4 = 1 which is the current followers. 300,000 multiplied by 4 = 1,200,000
Using percentages we know that the current followers of the sports franchise are (D) 1,200,000.
What are percentages?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.So, the current followers are:
Let the correct followers be x.Now calculate as follows:
x/100 × 25 = 300,00025x = 30,000,000x = 30,000,000/25x = 1,200,000Therefore, using percentages we know that the current followers of the sports franchise are (D) 1,200,000.

What is the relative frequency of students with high interest? A) 30% B) 50% C) 40% D) Cannot be de
Answer:
Relative frequency is the number of times an envent has occured.
When finding out the number of students with high interest you would take 30/100 because there was 30 students with high frequency and 100 students all together.
30/100=30%
A)30%
Hope this helps ;)
The relative frequency of students with high interest in the new International Studies program is 30%. This is calculated by dividing the number of high interest responses (30) by the total number of responses (100), and multiplying the result by 100.
Explanation:The question asks us to calculate the relative frequency of students with high interest in the new International Studies program. To do this, we divide the number of students with high interest by the total number of students surveyed.
The total number of students polled is 30 (high interest) + 50 (medium interest) + 20 (low interest), which equals 100 students. So, to calculate the relative frequency for students with high interest, we divide the number of students with high interest (30) by the total number of students surveyed (100).
The calculation is as follows: (30 / 100) * 100 = 30%
Therefore, the relative frequency of students with high interest is 30%, which corresponds to option A in your multiple choice question.

[tex]|3|=3[/tex]
[tex]|-3|=-(-3)[/tex] or just [tex]3[/tex] but there is a reason why I wrote it the way I did.
You see that the absolute value returned the same value if the value was positive.
You see that the absolute value returned the opposite value if the value was negative.
You can include 0 in either.

When is [tex]x+3[/tex] negative or zero? [less or equal to 0]

The area is 130ft.²
Best of Luck!
In mathematics, the perimeter of the 13ft by 10ft bedroom would be 46ft and the area would be 130 square feet.
Explanation:The perimeter of a rectangle (which a bedroom is 13ft. by 10ft. mostly is) can be determined by adding up all the sides. So, the formula for a rectangle is: Perimeter = 2(length + width). Given that your length is 13ft and width is 10ft, the calculation would be Perimeter = 2(13ft + 10ft), resulting in a perimeter of 46ft.
The area of a rectangle is calculated by multiplying the length by the width. In this case: Area = length * width, therefore Area = 13ft. * 10ft., resulting in an area of 130 square feet.

One month Donna rented 5 movies and 6 video games for a total of $48. The next month she rented 3 movies and 2 video games for a total of $18. Find the
rental cost for each movie and each video game.
Rental cost for each movie: s]
x
5
?
Rental cost for each video game: S
Answer:
Cost for each movie: $1.50 Cost for each video game: $6.75
Step-by-step explanation:
Let x be the cost (in dollars) of renting a movie.
Let y be the cost (in dollars) of renting a video game.
The total cost of renting 3 movies and 2 video games is +3x2y dollars.
We're given that this total cost is $18, so we have =+3x2y18.
The total cost of renting 5 movies and 6 video games is +5x6y dollars.
We're given that this total cost is $48, so we have =+5x6y48.
Therefore, we get the following system of equations.
=+3x2y18
=+5x6y48
Multiplying the first equation by −3 and adding gives us the following.
−9 x− 6 y = −54 5 x+ 6 y = 48 −4 x+ 0 y = −6
So we get the equation =−4x−6.
Solving for x, we get the following.
=x1.5
To find y, we can substitute 1.5 for x in =+3x2y18, the first equation in the system.
Then we solve for y.
+31.52y =18
+4.52y =18
2y =13.5
y =6.75
So, we have found that =x1.5 and =y6.75.
This means that the rental cost for each movie is $1.50 and the rental cost for each video game is $6.75.
