A median of a triangle always bisects the angle of the triangle that it intersects. true or false
Answer: True
Step-by-step explanation: Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length. The concept of a median extends to tetrahedra.
Answer:
True

find the amount of hardener needed for 600g of carbon fiber if the ratio of the composite is 40% matrix to 60% fiber and the ratio of the matrix is 100 parts resin to 27 parts of hardener
The hardener needed for 600 g of carbon fiber is 85.04 g.
We are given that the ratio of the composite is 40 % matrix to 60 % fiber.
This can be written as:
Matrix : fiber = 40 % : 60 %
Matrix : fiber = 40 : 60
Matrix : fiber = 2 : 3
Now, we know that the carbon fiber = 600 g
Matrix : 600 g = 2 : 3
Matrix / 600 = 2 / 3
Matrix = 1200 / 3 g
Matrix = 400 g
Also, we are given that the ratio of the matrix is 100 parts resin to 27 parts of hardener.
This means that:
Hardener = 27 / 127 of matrix.
Hardener = 27 / 127 × ( 400 g )
Hardener = 85.04 g
Therefore, the hardener needed for 600 g of carbon fiber is 85.04 g.

Evaluate each expression if a = 2, b = -34
3. - 9 (a-6)
Answer:
36
Step-by-step explanation:
I'm assuming the expression we're solving here is -9(a-6).
-9(2-6)
(-9*2)-(-9*6)
(-18)-(-54)
Simplify.
-18+54
It equals 36.

Ramon places a mirror on the ground 45 ft from the base of a geyser. He walks backwards until he can see the top of the geyser in the middle of the mirror. at that point, Ramon eyes are 6 ft above the ground and he is 7.5 ft from the mirror. Use similar triangles to find the geyser
Answer:
36 ft
Step-by-step explanation:
6/x=7.5/45
270=7.5x
x=36
In this exercise we have to have knowledge of triangles, so we can use the theory of similar triangles to find the value of X, like:
[tex]36 ft[/tex]
To use similar triangle theory, we have to make a rule of 3, that is:
[tex]6/x=7.5/45\\270=7.5x\\x=36[/tex]

The table represents a proportional relationship between the number of hours it shows h, and the number of inches of snow, s on the ground. Find the constant of proportionality
The constant of proportionality is.
The constant of proportionality is 4, and the relationship is given by s = 4h.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let h represent the number of hours and s represent the number of inches of snow on the ground. Since both variables are proportional, hence:
s = hk; where k is the constant of proportionality
Let us assume in the table, when h = 1, s = 4 hence:
s = hk
4 = k(1)
k = 3
s = 4h
The constant of proportionality is 4, and the relationship is given by s = 4h.

Which of the following equations has an infinite number of solutions?
A. 3x – 3 = –4x
B. 2y + 4 – y = 16
C. 7x + 5 = 4x + 5 + 3x
D. 6y – 2 = 2(y – 1)
The equation 7x + 5 = 4x + 5 + 3x has an Infinite number of solutions. which is the correct answer would be option (C).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine which equation has an infinite number of solutions
As per option (C),
⇒ 7x + 5 = 4x + 5 + 3x
Combine comparable terms to simplify both sides of the problem.
You have become left with 7x+5 = 7x+5.
On both sides, subtract 7x.
This gives you 5=5.
Subtraction 5 from both sides
⇒ 0 = 0
Thus, this equation has an Infinite number of solutions.
Hence, the correct answer would be an option (C).

Given CAD is a right angle and AB is bisecting CAD and if DAB=(7x-4) find X
Answer:
x = 7
Step-by-step explanation:
∠CAD is a right angle, right angles has 90° measurement.
m∠DAB = 7x - 4 AB bisects ∠CAD this means it divides the angle into two equal parts.
So it's safe to write the following equation:
7x - 4 = 45 (half of 90°)
add 4 to bot sides
7x = 49 divide both sides by 7
x = 7

A boy scout troop is selling bags of popcorn and boxes of cookies to fund their troops next trip. The popcorn sells for 10 dollars a bag and the cookies sell for 5 dollars a box. The troop sells 32 items and makes 210 dollars. Write a system that could be used to determine how much popcorn and cookies the troop sold.
Answer:
c + p = 32
5c + 10p = 210
Step-by-step explanation:
Given that :
Cost of popcorn per bag = $10
Cost of. Cookies per box = $5
Total items sold = 32
Total.amout made = $210
Let number of cookies = c ; number of popcorn = p
c + p = 32
5c + 10p = 210
c = 32 - p
5(32 - p) + 10p = 210
160 - 5p + 10p = 210
5p = 50
p = 10
c = 32 - p
c = 32 - 10
c = 22
