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 2 x + 10, the length of line segment F G is 2 x minus 1, and the length of line segment G B is 3 x + 6.
G is the centroid of triangle ABC.
What is the length of AE?
units
Answer:
The length of AE is 39 units.
Step-by-step explanation:
Given:
G is the centroid of a triangle ABC.
Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments AE, BF, and CD.
The length of line segment A G is 2 x + 10, the length of line segment F G is 2 x minus 1, and the length of line segment G B is 3 x + 6
To Find: Length of the AE.
The centroid of the triangle is always cut the line in the ratio of 2:1. For clarification, the image is provided.
Hence,
G divides the line BF into a 2:1 ratio.
Thus,
[tex]\begin{aligned}&2FG=BG\\&2(2x-1)=3x+6\\&4x-2=3x+6\\&x=8 \end{aligned}[/tex]
Also,
G divides the line AE into a 2:1 ratio.
Therefore,
[tex]AG=2GE\\GE=AG/2[/tex]
Line segment AE is the sum of AG and GE.
Thus,
[tex]AE=AG+GE\\AE=AG+AG/2\\AE=3AG/2\\AE=3(2x+10)/2\\AE=39[/tex]

The length of AE is 9 units.
Given that G is the centroid, it divides each median into two segments with the ratio of 2:1, where the longer segment is toward the vertex and the shorter segment is toward the midpoint of the opposite side.
Let's denote the length of AG as a, the length of BG as b, and the length of FG as c. According to the given information:
1. AG = 2x + 10
2. FG = 2x - 1
3. BG = 3x + 6
We know that AG = 2GE and BG = 2GE. Thus:
[tex]\[ AG = 2GE \implies GE = \frac{AG}{2} = \frac{2x + 10}{2} = x + 5 \]\[ BG = 2GE \implies GE = \frac{BG}{2} = \frac{3x + 6}{2} = \frac{3}{2}x + 3 \][/tex]
Since GE is common, we can equate the expressions:
[tex]\[ x + 5 = \frac{3}{2}x + 3 \][/tex]
Solving for x:
[tex]\[ \frac{1}{2}x = 2 \][/tex]
x = 4
Now that we've found the value of x, we can substitute it back into the expressions for AG and FG to find their lengths:
AG = 2x + 10 = 2(4) + 10 = 18
FG = 2x - 1 = 2(4) - 1 = 7
Now, we know that AE = AG - GE:
AE = AG - GE = 18 - (x + 5) = 18 - (4 + 5) = 18 - 9 = 9
So, the length of AE is 9 units.

The length of a rectangle is 4 more than 3 times the width. If the perimeter of the rectangle is 18.4 cm, what is the area of the rectangle?
Area of the rectangle is 10.27 cm²
Step-by-step explanation:
Step 1: Let the width of the rectangle be x, then length = 4 + 3x. Find the dimensions if perimeter = 18.4 cmPerimeter = 2(length + width)
⇒ 18.4 = 2 (x + 4 + 3x)
⇒ 18.4 = 2(4x + 4)
⇒ 18.4 = 8x + 8
⇒ 8x = 10.4
⇒ x = 10.4/8 = 1.3
∴ 4 + 3x = 4 + 3×1.3 = 7.9
Step 2: Find area of the rectangle.Length = 7.9 cm and width = 1.3 cm
⇒ Area = length × width
= 7.9 × 1.3 = 10.27 cm²
How do u graph y=15x+35?
Hey there!
This is slope intercept form, where y=mx+b, where b is the y-intercept (where the line hits the y-axis) and the slope (rate of change).
If you wanted to graph this line, we can see that the y intercept in 35. Therefore, our line is going have one point on (0,35). Our slope is 15, which is positive, showing that our line will go up. Because the slope is fifteen, for every single increase of 1 there is in x, there will be an increase of 15 in y. This will give us points like (1,15) (2,30) (3,45). Therefore, this will be a very steep line.

Determine whether the two expressions are equivalent. If so, tell what property is applied.
(20 – 4) – 2 and 20 – (4 – 2)
Both expressions (20 – 4) – 2 and 20 – (4 – 2) are equivalent, simplifying to 14. The equivalence exemplifies the Associative Property of Addition.
The question asks to determine whether the two expressions (20 – 4) – 2 and 20 – (4 – 2) are equivalent, and if so, to identify the property applied. To determine equivalence, we need to simplify both expressions. The first expression, (20 – 4) – 2, simplifies to 16 – 2 which equals 14. The second expression, 20 – (4 – 2), simplifies to 20 – 2 which also equals 14. Therefore, both expressions are equivalent, and the property applied here is the Associative Property of Addition, which allows us to change the grouping of the numbers we're adding (or subtracting, in this case) without changing the result.

One yard crew works four times faster than the other yard crew. If they work together they can finish a job in 60 minutes. How fast each yard crew works?
Time taken by both crew is 48 min and 12 min , when they work together !
Step-by-step explanation:
Here we have , One yard crew works four times faster than the other yard crew. If they work together they can finish a job in 60 minutes. We need to find How fast each yard crew works . Let's find out:
One yard crew works four times faster than the other yard crew
Let speed of one crew be x , So speed of other crew is four times i.e.
⇒ [tex]4x[/tex]
If they work together they can finish a job in 60 minutes.
According to above statement , both can finish work in 60 min i.e.
⇒ [tex]4x+x=60[/tex]
⇒ [tex]5x=60[/tex]
⇒ [tex]x=12[/tex]
So , time taken by other crew is 4x = 4(12) = 48 min . Therefore , Time taken by both crew is 48 min and 12 min , when they work together !
The second yard crew works for 48 minutes.
The first yard crew works for 12 minutes which is four times faster that the second crew.
Step-by-step explanation:
Let us assume,
The second yard crew completes the work in 'x' minutes.
It is given that,
The first yard crew works four times faster than the other yard crew. Therefore, first yard crew will complete the work in 'x/4' minutes.If they work together they can finish a job in 60 minutes.
⇒ x + x/4 = 60 minutes.
⇒ 5x / 4 = 60
⇒ x = 240/5
⇒ x = 48 minutes.
Therefore, the second yard crew works for 48 minutes.
To find the first yard crew :
We already know that, they are 4 times faster that the second yard crew.
Substitute x = 48 in x/4,
⇒ 48 ÷ by 4
⇒ 12 minutes.
Therefore, the first yard crew works for 12 minutes which is four times faster that the second crew.
An electronics store reduced the price of a TV from $1000 to $880. What was the percent of decrease?
Answer:
12% decrease
Step-by-step explanation:
think of 1000 as 100% and thin 880 as 88% subtract those 12%
The price decrease from $1000 to $880 represents a 12% decrease. This is figured out by taking the difference in price, dividing it by the original price, and then multiplying by 100%.
Explanation:The percentage decrease is calculated by taking the difference in price divided by the original price, and then multiplying by 100 to get a percentage. In this case, the difference in price is the original price minus the sale price. This would be $1000 - $880 = $120. So, the formula would be ($120/$1000)*100. The calculated percentage decrease is 12%, meaning the price of the TV has been reduced by 12%.

A movie theater sells small and large boxes of popcorn.
• A small box of popcorn costs $1.50.

There 15 large boxes of popcorn were sold. The option D is correct.
We need to determine the number of large boxes of popcorn sold. Let's denote the number of small boxes as s and the number of large boxes as l. We are given the following information:
The cost of a small box of popcorn is $1.50.
The cost of a large box of popcorn is $4.00.
A total of 25 boxes of popcorn were sold.
The total revenue from popcorn sales was $75.00.
We can set up two equations based on this information:
s + l = 25 (the total number of boxes sold)
1.50s + 4.00l = 75.00 (total revenue from sales)
Let's solve for l using these equations. Multiplying the first equation by 1.50 gives us:
1.50s + 1.50l = 37.50
Subtracting this from the second equation:
(1.50s + 4.00l) - (1.50s + 1.50l) = 75.00 - 37.50
2.50l = 37.50
l = 37.50 / 2.50
l = 15
Brandy drove three times as far as Trisha. Together, they drove 48 miles. Which equation below can be used to find the number of miles Trisha drove?
