Four triangles are shown. One side of each triangle lies on a ray, and the triangles are not drawn to scale. Based on these triangles, which statement about x is true?

Answer:

50 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees. We would set up the equation like this:

2x+18 + 4x+11 + 55 = 180

Combine like terms:

6x + 84 = 180

Solve for x:

6x = 96

x = 16

We substitute 16 back in for x and see the measure of the smallest angle.

2(16)+18 = 50

4(16)+11 = 75

55

The smallest angle here in 50 degrees.

Answer:

2x + 18 = 50

Step-by-step explanation:

2x + 18 + 4x + 11 + 55 = 180

6x + 84 = 180

180 - 84 = 96

6x = 96

96/6 = 16

x = 16

2(16) + 18 = 50

55

4(16) + 11 = 75

Answer:

The constant of proportionality is 3.

Step-by-step explanation:

Constant of proportionality is found by doing k = [tex]\frac{y}{x}[/tex]. Point (2,6) is on the line, so if we plug in point (2, 6) into the equation to solve for the constant of proportionality, we get [tex]k=\frac{6}{2}[/tex] or k = 3. The constant of proportionality is 3.

Answer:

C

Step-by-step explanation:

In A, its :            10 - 3 x (4-5)

In B, it's :            (10-3) + 5

In D it's:            Nonsense

The only true answer is C:      (10-3)  x 4 + 5

Step-by-step explanation:

f(x)=x*3+4-2

f(3)  =   11     3*3+4-2

f(2)=8                2*3+4-2

f(9)=29         9*3+4-2

Answer:

1) D.208

2) C.112

Step-by-step explanation:

so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together

l= length

w=width

a=area

4*8=32

4*8=32

6*4=24

6*4=24

6*8=48

6*8=48

48+48+24+24+32+32=208

208[tex]cm^{2}[/tex]

for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.

for the triangles you're gonna wanna use the equation 1/2b*h=a

b= base

h=height

a=area

7*4=28

7*4=28

7*4=28

7*4=28

28*4=112

Step-by-step explanation:  L+L+W+W=Perimeter

2(1/4x)+2(2x+1)=4.5x+2            

4.5x+2=29        Subtract 2

4.5x=27             Divide by 4.5

x=6                                                            1/4(6)= 1.5 W=1.5      1.5(2)=3

                                                                 2(6)+1=13                  13(2)=26

                                                                                   26+3=29inches perimeter

Answer:

A: 12 4/9

Step-by-step explanation:

1/4x (2x + 1) = 29 (Combine like terms, NOT distributive property!!!)

   2 1/4x + 1 = 29

               - 1    - 1

2 1/4 / 2 1/4x = 28 / 2 1/4

                  x = 12 4/9

A dot plot titled Number of Hours Spent on Homework goes from 1 to 6. There is 1 dot above 1, 5 dots above 2, 6 dots above 3, 4 dots above 4, 1 dot above 5, and 1 dot above 6. What is a dot plot and how do you read it? Check all that apply. A dot plot is a simple plot that displays data values as dots above a number line. Dot plots show the frequency with which a specific item appears in a data set. 3 students spent 4 hours on homework. 5 students spent 2 hours on homework. Dot plots show the distribution of the data. Students spent 1 to 6 hours on homework.

Answer:

8(a+4)= 8a + 32

Step-by-step explanation:

Answer:

B) 20

Step-by-step explanation:

30 = 150% × Y

30 = 150/100 x Y

Y = 30 x 100 divided by 150

Y = 20.

Faster way: 30 x 100 divided by 150.

Hope this helps!

a. it is not, because dividing 1.875 by 500 would not equal 0.015.
