Tracy found the length of GF. Her work is shown below.

Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A E, B F, and C D. The length of line segment A G is 16, the length of line segment G E is 2 x, and the length of line segment B G is 8 x.

16 = 2(2x)
16 = 4x; x = 4
8(4) = 32
GF = 2(32)
GF = 64
What error did Tracy make?

She used AG = 2EG, but the correct statement is 2AG = GE.
She found that x = 4, but the correct value for x is 2.
She used GF = 2BG, but the correct statement is BG = 2GF.
She found that GF = 64, but the correct value of GF is 8.

Louis and Max are contestants in a jellybean-eating contest. Louis eats 18 jellybeans
in 30 seconds. Max eats 24 jellybeans in 40 seconds.

Answers

Answer: They ate at the same pace.

Step-by-step explanation: assuming you want to know who ate more faster you can do 18 / 30 and 24 / 4 to find out who ate more in 10 seconds each.

18 / 3 = 6 and 24 / 4 = 6. So they ate at the same speed / pace.

Help ASAP pls What is the y intercept of the linear equation shown on the graph

A. (0,-70)
B. (0,-50)
C. (0,1/2)
D. (0,100)

Answers

Answer:

(0, -50)

Step-by-step explanation:

pick any 2 points such as (100,0)  and (120,10)

to get from point (100.0) to point (120,10) you had to rise 10 and run 20

so the slope m =rise 10/run20= 1/2

the equation of the line is (y-y1)=m(x-x1)

(y-0)=(1/2)(x-100) for the slope m=1/2 and point on the line (100,0)

y=( x/2)-50 if you distribute

compare this with the equation

y=mx+b wher m=slope and bb is y-intercept

so the y-intercept is -50

b

Answers

Answer:

a=15

Step-by-step explanation:

2a-10=20

2a=30

a=15

can i have one brainliest plz

Answer:

a = 15

Step-by-step explanation:

I assumed you were trying to solve for A :)

3a - 10 = a + 20

1. Combine like terms (A's on side, numbers on the other).

3a - 10 = a + 20

-a           -a

-----------------------

2a - 10 = 20

     +10   +10

------------------------

2a = 30

Now that all of your like terms are combined, work to isolate A. The only way to do this is to divide by 2 on both sides of the equal sign.

[tex]\frac{2a}{2} = \frac{30}{2}[/tex]

This leaves you with a = 15, which is your answer if you are told to solve for A

14x=12x+6

2x=6

x=3

subsitute x=3

y=14(x)   turns into y=52

x is 3 y is 52

2.

x+20=y  since alternate interior

y+2x+10=180    because they are supplementary

x+20+2x+10=180    subsitute  for y

3x+30=180

3x=150

x=50

The value of x is 3

Step-by-step explanation:

∵ Quadrilateral ABCD is congruent to quadrilateral JKLM

∴ AB = JK and BC = KL

∴ CD = LM and AD = JM

∵ BC = 8x + 7

∵ KL = 31

∵ BC = KL

→ Equate their right sides

8x + 7 = 31

→ Subtract 7 from both sides

∵ 8x + 7 - 7 = 31 - 7

∴ 8x = 24

→ Divide both sides by 8 to find x

∴ [tex]\frac{8x}{8}[/tex] = [tex]\frac{24}{8}[/tex]

x = 3

A sock drawer has 17 folded pairs of socks, with 5 pairs of white, 8 pairs of black and 4 pairs of blue. What is the probability, without looking in the drawer, that you will first select and remove a black pair, then select either a blue or a white pair?

Answers

Answer:

26.4%

Step-by-step explanation:

PLS GIVE BRAINLIEST

The probability of selecting a black pair of socks first, then a blue or white pair of socks is 27/136.

The probability of selecting a black pair of socks first is:

probability = (number of black pairs)/(total number of pairs)

= 8/17

Once a black pair of socks has been selected, there are 16 pairs of socks left in the drawer. Of these 16 pairs, 9 are either blue or white.

The probability of selecting a blue or white pair of socks second is:

probability = (number of blue and white pairs)/(number of remaining pairs)

= 9/16

Therefore, the overall probability of selecting a black pair of socks first, then a blue or white pair of socks is:

probability = (8/17)*(9/16)

= 27/136

What is the image of -1,-4 after a reflection over the x axis

Answers

answer: the image is (-1,4)

The image of the point after the reflection over x axis is P' ( -1 , 4 )

What is Reflection?

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the point be represented as P

Now , the coordinates of the point P is P ( -1 , -4 )

The point P is reflected over the line x axis ,

So , when you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

Substituting the values in the equation , we get

The image of the reflected point is P' ( -1 , - ( -4 ) )

The image of the reflected point is P' ( -1 , 4 )

Hence , the reflected point is P' ( -1 , 4 )

Step-by-step explanation:

Answer:

x = 60°

Step-by-step explanation:

we know that triangles have 180 degrees so we can set up an equation:

86 + 34 + x = 180

now we subtract the sum of 86 and 34 from both sides to get a final answer:

x = 60

so lets plug our x value into the previous equation to check our answer:

86 + 34 + 60 = 180

when we add these numbers together, the equation checks out so we know our answer is correct.

A glass is
1
6
full. Then 95cm3 of orange juice is poured in.
The glass is now
4
5
full. What is the total volume of the glass?

Answers

Answer:

let x = the amount of orange juice in a full glass.

the glass is 1/6 full = 1/6 * x

add 95 cubic centimeters and the glass becomes 4/5 full.

equation for that is:

1/6 * x + 95 = 4/5 * x

subtract 1/6 * x from both sides of this equation to get:

95 = 4/5 * x - 1/6 * x

multiply 4/5 * 6/6 and multiply 1/6 * 5/5 and the equation becomes:

95 = 24/30 * x - 5/30 * x

combine like terms to get 95 = 19/30 * x

multiply both sides of the equation by 30/19 to get:

30/19 * 95 = 30/19 * 19/30 * x

simplify to get:

30/19 * 95 = x

solve for x to get x = 150.

the volume of the glass is 150 cubic centimeters.

1/6 * 150 = 25

4/5 * 150 = 120

the difference between 4/5 full and 1/6 full is 95 cubic centimeters.

solution is that the volume of the glass is 150 cubic centimeters.
