Answer:

w=9x+4

Step-by-step explanation:

2(3x-3+w)=12x+2

6x-6+2w=12x+2

subtract 6x for both sides

-6+2w=18x+2

add 6 for both sides

2w=18x+8

Divide by 2 to find w

w=9x+4

Help please i suck at geometry

Tems11 [23]

Answer:

Step-by-step explanation:

10 and 8 are equal

11 and 15 are equal

due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees

180-42=138 degrees

and this means that angle 8 will also be 138 because of what we established earlier

1.a sphere with a radius of three units

By definition, the volume of a sphere is:
$V = ( \frac{4}{3} ) (\pi) (r ^ 3)
$
Substituting values we have:
$V=(\frac{4}{3})(\pi)(3^3)$
Rewriting we have:
$V = (4) (\pi) (3 ^ 2)

V = (4) (\pi) (9)

V = 36\pi$

2.a cone with a diameter of twelve units and a height of three units

By definition, the volume of a cone is given by:
$V = \frac{1}{3} (\pi) (r ^ 2) (h)
$
Substituting values we have:
$V = \frac{1}{3} (\pi) ((\frac{12}{2}) ^ 2) (3)
$
Rewriting we have:
$V = (\pi) (6 ^ 2)

V = 36\pi$

The room numbers of two adjacent classrooms are two consecutive even integers. If their sum is 654, find the classroom numbers.

IRINA_888 [86]

Answer: It is 326 and 328.

Step-by-step explanation: We know that the numbers must be even and consecutive, so we can figure this problem out by trial and error. Divide 654 by two, and then keep going until you get the proper answer.

CAN SOMEONE JUST ANSWER THIS QUESTION

Answer:

1/5

Step-by-step explanation:

There are 3 numbers of less than 4 (1, 2 and 3) and there are 2 multiples of 9 (9 and 18). So there are 5 favourable outcomes and 25 possible outcomes. So you put 5/25 and cancel down, which makes 1/5. I hope this helps!

Answer:

150.72 units³

Step-by-step explanation:

The formula for solving the volume of a cylinder is:

V = pi (3.14) r² h

V = (3.14) (4) (3)

V = 150.72 units³
