What is the volume of both shapes ?

Nataly [62]

Answer:

314 ft cubed

Step-by-step explanation:

To find the volume, find the volume of the cone and add it to the volume of the cylinder.

The volume of a cone is

$V= \frac{1}{3}\pi r^2 h= \frac{1}{3}\pi (5^2)(12) = \frac{1}{3}\pi (25)(12)= \frac{1}{3}\pi *300 = 100\pi$ .

The volume of the cylinder is

$V=\pi (5^2)(4)= \pi (25)(4)= 100\pi$

Together their volume is $100\pi+100\pi=200\pi \\200\pi =314ft^3$

50 POINTS+BRAINLIEST!!!!

Ilya [14]

Answer: So, we know that the internal angles of a triangle add up to 180 degrees, yes?

60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.

Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!

Brainliest please if I am correct! and hope it helped.

Create an expression equivalent to 2 (3x =1) 3x+4 using the least number of terms

Mariana [72]

Answer:

$18x^2 + 18x -8$

Step-by-step explanation:

To use the least number of terms, simplify the expression. To simplify, distribute into the parenthesis and combine like terms.

$2(3x-1)(3x+4) = 2(9x^2-3x+12x-4) = 2(9x^2+9x-4) = 18x^2 + 18x -8$

Math question picture attached

babunello [35]

To find the slope, you use the slope formula (m):

$m=\frac{y_2-y_1}{x_2-x_1}$ and plug in the two points

(-3, 4) = (x₁, y₁)

(2, -1) = (x₂, y₂)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-1-4}{2-(-3)}$ [two negatives cancel each other out and become positive]

$m=\frac{-1-4}{2+3}$

$m=\frac{-5}{5}$

m = -1 The slope is -1
