We know at centroid medians bisect each other in the ratio 2:1.

  • TY=30
  • Let YW be x

\\ \sf\longmapsto TY=2x

\\ \sf\longmapsto 2x=30

\\ \sf\longmapsto x=\dfrac{30}{2}

\\ \sf\longmapsto x=15

Answer:

A

Step-by-step explanation:

On the median TW the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint , then

YW = \frac{1}{2} × TY = \frac{1}{2} × 30 = 15

Question 2 (1 point)<br> What is the value of x if AABC is equilateral?
Marina86 [1]

Answer:

x= 2

Step-by-step explanation:

Given that,

AB = 7.5x

BC = 6x+3

AC = 10x-5

ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,

AC = BC = AB

10x-5 = 6x+3

Taking like terms together

10x-6x = 5+3

4x = 8

x = 2

Hence, the value of x is equal to 2.

A train travels 16 miles in 20 minutes At this rate , how many minutes will it take to trace 12 miles?
umka2103 [35]

Answer:

15 minutes

Step-by-step explanation:

You must find the unit rate.

You can find this by dividing 16 miles by 20 minutes

This formula would find how many per minute

The answer would be .64 miles per minutes.

Then Multiply .64 by 12 which would give you the answer of 7.68

state whether the following statement is true or false: y= -x2 + 6x - 10 does not intersect the x-axis.​
oee [108]

Answer:

True

Step-by-step explanation:

Here, we want to check if the given equation does not intersect the x-axis

if it does not, then it has no real root

If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis

The formula for the discriminant is;

D = b^2-4ac

In the question;

a = -1 , b = 6 , c = 10

so;

D = 6^2-4(-1)(10)

D = 36-40

D = -4

Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis

(a) <br> 127.5<br> is what percent of <br> 51<br> ?
ExtremeBDS [4]
To solve this, you need to divide 127.5 by 51:
127.5/51 = 2.5
To find the percent, multiply 2.5 by 100:
2.5 x 100% = 250%
So 127.5 is 250% of 51

HELP?
poizon [28]
My "work" is to enter the equations into a graphing calculator and let it show me the answers--just as your "work" is to copy the question to Brainly.

The solutions are
  (x, y) = (-0.5, 7.5)
  (x, y) = (3, 25)

_____
When you equate the expressions for y, you get the quadratic
  2x² -5x -3 = 0
  (2x +1)(x -3) = 0
  x = -1/2 or 3
  y = 5(x +2) = 15/2 or 25
