Answer:

The average value of a, b and c is [tex]\frac{2c}{3}[/tex]

Step-by-step explanation:

Average value:

Sum of all values by the number of values.

In this question:

3 values, a, b and c.

We have that:

[tex]A = \frac{a+b+c}{3}[/tex]

Since [tex]a+b = c[/tex]

[tex]A = \frac{a+b+c}{3} = \frac{c+c}{3} = \frac{2c}{3}[/tex]

The average value of a, b and c is [tex]\frac{2c}{3}[/tex]

Answer:

surface tension

Answer:

64 degrees

Step-by-step explanation:

Since the triangles are similar they have the same angle measures

[tex]\frac{PR}{PQ} =\frac{SU}{ST}[/tex]          [tex]\frac{21}{14}= \frac{6}{4}[/tex]

∠P = ∠S ∠R =∠U ∠Q=∠T

We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U

In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula

[tex]A+B+C=180[/tex]

[tex]46+70+C+180[/tex]

[tex]116+C=180[/tex]

subtract 116 from both sides

[tex]C=64[/tex]

Therefore ∠Q is equal to 64 degrees

Answer:

y = -16

Step-by-step explanation:

−10y+4(3y−8)=−64

Step 1: Simplify both sides of the equation.

−10y+4(3y−8)=−64

−10y+(4)(3y)+(4)(−8)=−64(Distribute)

−10y+12y+−32=−64

(−10y+12y)+(−32)=−64(Combine Like Terms)

2y+−32=−64

2y−32=−64

Step 2: Add 32 to both sides.

2y−32+32=−64+32

2y=−32

Step 3: Divide both sides by 2.

2y

2

=

−32

y=−16

Answer:

Step-by-step explanation:

Question: What is g³ - h² + 8, when g= 3, h = 5

Substitute the given values

3³ - 5² + 8

Simplify exponents- remember, 3³ = 3 * 3 * 3, and 5² = 5 * 5

27 - 25 + 8

Simplify

-2 + 8 =

Answer:

[tex](x -3 )^2 = 10[/tex]

Step-by-step explanation:

Given

[tex]x^2 - 6x - 1 = 0[/tex]

Required: Express as a perfect square

[tex]x^2 - 6x - 1 = 0[/tex]

Add 10 to both sides

[tex]x^2 - 6x - 1 +10= 0+10[/tex]

[tex]x^2 - 6x +9= 10[/tex]

Expand

[tex]x^2 - 3x - 3x+9= 10[/tex]

Factorize:

[tex]x(x - 3) - 3(x - 3)= 10[/tex]

Factorize:

[tex](x -3 )(x - 3) = 10[/tex]

[tex](x -3 )^2 = 10[/tex]

Answer:

Need to see the statements

Step-by-step explanation:

Answer:

A)  36√3

Step-by-step explanation:

First, figure out the height.  Since it's an equilateral triangle, it would be

6²+B²=12²

36+B²=144

B²=144-36

B²=108

B=√108

B=√36x√3

B=6√3

Now we can get the area.

1/2(6√3)(12) = 36√3

Step-by-step explanation:

u-42+u-43+u-44=180

u = 103

This article is about equivalency in mathematics. For equivalency in music, see equivalence class (music).

Congruence is an example of an equivalence relation. The leftmost two triangles are congruent, while the third and fourth triangles are not congruent to any other triangle shown here. Thus, the first two triangles are in the same equivalence class, while the third and fourth triangles are each in their own equivalence class.

In mathematics, when the elements of some set S have a notion of equivalence (formalized as an equivalence relation) defined on them, then one may naturally split the set S into equivalence classes.

Answer:

To find the area of the rectangular prism, use the formula:

A = width x height x length

A = 2 x 2 x 3

A = 12

Now multiply A with 0.75

12 x 0.75 = 9

x = 9 in³
