B)2(x + 2y) and 2x + 4y
C)2(3x + 2y) and 6x + 4y
D)2(3x + 6y) and 6x + 12y
Answer:
B
Step-by-step explanation:
2(x+2y)=2x+4y
2x+4y

if there is 16 boys in the classroom are 40% of the class, how many students are there in the class
Answer:
40 students
Step-by-step explanation:
16 = 40%
Divide by two to get 20% = 8
Then multiply by 5 to get 40 = 100%
There’s other ways to do this, BUT this is the way that I solve it.
Find the scale factor of the dilation.
The scale factor is
Answer:
2
Step-by-step explanation:
its the wrong anwser
Answer:
0.5
Step-by-step explanation:
Scale factor is the final size (of image D'E'F'G') compared to that of the original (DEFG).
So the dilation factor is 3/6 = 0.5 (less than one means diminution in size.

Determine the missing side of the square.
Answer:
The missing side is 9cm.
How I got my answer:
1. Squares have equal sides.
2. The area is 81cm^2, so we have to divide 81 by 9.
81 : 9 = 9cm.
Answer:
Length of the side W = 9cm
Step-by-step explanation:
A square has all sides equal. So since one side is 9cm, the rest will be 9cm as well. The side marked as 'W' is 9cm.
You can find this in another way (if the length of the sides aren't given) :-
The area is 81[tex]cm^{2}[/tex]
[tex]side^{2}[/tex] gives the area
Let's take the side as x.
So,
[tex]x^{2}[/tex] = Area
[tex]x^{2}[/tex] = 81[tex]cm^{2}[/tex]
x = [tex]\sqrt{81}[/tex]
x = 9cm.
So, each side of the square would be 9cm!

A 7 m rope is attached to the wall of a garage. A dog’s collar is attached to the rope, allowing the dog to safely roam the yard. What is the area that the dog has to roam outside?
Well, if you think about it, its a half circle. We know that if the dog pulls straight then the radius if this were a full circle would be 7. So the Area of a circle is A=Pi Radius Square. For us it will be divided by 2 since its a half circle. So were going to round pi to 3.14 and now..
3.14(49)=153.86. So that is an area of the full circle. DIvided by 2 we get 76.93.
I am pretty sure its correct so your answer is 76.93 m
If it was helpful, hit that heart button, thanks :D

76.93m

A stockpile of dirt is being stored at a construction site. The dirt is roughly shaped like a cone with a height of 45ft and a diameter of 60ft. What is the estimated volume of the dirt pile?
A. 42,390
B. 127,110
C. 1,400
D. 380,000
Answer:
A.
Step-by-step explanation:
The formula for the volume of a cone is [tex]V=\frac{1}{3} h\pi r^2[/tex]
Where h is the height and r is the radius.
In this case, h = 45 ft and r = 60 /2 = 30.
[tex]V =\frac{1}{3} *45\pi *30^2\\V = 42411[/tex]
The answer closest to this is A: 42,390.

Answer: 1st choice and the Second choice
Step-by-step explanation: Please give brainliest :)
The rectangle will be with width 2 cm and length 3 cm. The triangle will have base 2 cm and height 3 cm.
Area of triangle would be.
Sum of both areas would be.Therefore, 1st option is correct choice.
We can also divide area of irregular figure into triangles as shown in the attached file.
The base of one triangle would be 2 cm and other triangle will have a base of 4 cm. The heights of both triangles would be 3 cm.
Area of both triangles would be . Therefore, 2nd option is correct as well.
Triangle ABC has vertices with the following coordinates:
A(-1,3), B(0,4), C(1,1)
The triangle is translated 3 units to the left and 1 unit down to generate triangle A'B'C'.
Fill in the numerical values for the coordinates of the new vertices.
A' = ( , )
B' = ( , )
C' = ( , )
Answer:
A'= (-4,2)
B'= (-3,3)
C'= (-2,0)

A recipe for modeling clay requires 1/3 cup of salt. How many recipes of clay can Carla make with 7 3/4 cups of salt?
Answer:
About 23 cups
Step-by-step explanation:
Answer:
- The error is: (31/4) (1/3)
- The correct solution is: 93/4 =23 1/4 (Carla can make approximately 23 recipes with the clay).
Step-by-step explanation:
1. Carla must divide 31/4 ÷ 1/3 as following:
- Take the reciprocal of .
- Multiply the numerators and the denominators.
Then:(31/4) (1/3) = (31)/4 (3)/1 = 93/4
2. As a mixed number: 93/4 = 23 1/4
3. Therefore, Carla can make approximately 23 recipes with the clay.
- The error is:
- The correct solution is: (Carla can make approximately 23 recipes with the clay).

Two lines, C and D, are represented by the equations given below:
Line C: y = x + 10
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why?
answer choices
(5, 17), because one of the lines passes through this point
(5, 17), because the point lies between the two axes
(4, 14), because the point does not lie on any axis
(4, 14), because both lines pass through this point
Answer:
(4,14) because both lines pass through it.
Step-by-step explanation:
A "solution" to a system of equations is simply a point that both lines pass through.
First image is the solution found through graphing and the second image is the solution found through substitution.
