Answer:

A. 22

Step-by-step explanation:

Let's use variables to represent the unknowns.

Let x = blue bowl

Let y = orange symbol

Let z = yellow brush

x * x * x = 512

x^3 = 512

x = sqrt^3(512) = 8

xy^2 = 72

8 * y^2 = 72

y^2 = 9

y = 3

yz = 33

z = 11

x + y + z = 8 + 3 + 11 = 22

Answer:

A

Step-by-step explanation:

8x8x8=512

8x3x3=72

3x11=33

Therefore...

8+3+11=22

Their are 6 equilateral triangles in a regular hexagon:
The area of one triangle = (x²√3)/4, then:
1st answer: The area of the hexagon base: is  6 TIMES the area of one equilateral triangle [or, needed for 2nd, question, TOT AREA:(6x²√3)/4] = (3x²√3)/2] unit²

2nd answer: :
Volume of pyramid: (base area)(height)/3
Volume of pyramid: (3x²√3).(3x)/3 (because height = 3x, given)
Then Volume of pyramid= 3x³√3 unit³.
3 is the answer for the second question
and 6 for the 1st

Find the x-intercept and
svetlana [45]

9514 1404 393

Answer:

  x-intercept: (16, 0)

  y-intercept: (0, 8)

Step-by-step explanation:

Each intercept is found by setting the other variable to zero and solving for the variable of interest.

I like to find the intercepts from this form because it basically involves dividing the constant by the variable coefficient.

<u>x-intercept</u>

  y = 0, so we have 4x = 64   ⇒   x = 64/4 = 16

  x-intercept is (16, 0)

<u>y-intercept</u>

  x = 0, so we have 8y = 64   ⇒   y = 64/8 = 8

  y-intercept is (0, 8)

_____

<em>Additional comment</em>

There is a form of the linear equation called the "intercept form" that looks like this:

  x/a +y/b = 1

where 'a' is the x-intercept and 'b' is the y-intercept.

You can get this form by dividing the standard form equation by the constant. Here, that gives ...

  4x/64 +8y/64 = 1

  x/16 +y/8 = 1

This is nice because it gives both intercepts with one operation (divide by the constant). It's easy enough to do, but not always easy to explain. This form of the equation of a line is rarely seen.

Can someone pls help? ab to fail geometry. any help is nice.
Mamont248 [21]
By the law of cosines, the angle C satisfies

8.77^2=2^2+9^2-2\times2\times9\times\cos C

which reduces to

\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).

Which table does not represent a function?
Mrrafil [7]

Answer:

B

Step-by-step explanation:

To be a function every input must have exactly one output. There are two input values with 2, therefore this makes it not a function.
