First find volume of prism by doing l*w*h so 12*4*6=288
Then find volume of triangular prism by doing 1/2*b*h*l so 1/2*6*6*4=72
Lastly add these 2 together for the volume of the entire composite shape:
288+72
=360

If I have (-2, 7) and (6, y) distancia = 10 . How can I find y?
shusha [124]

Answer:

y = 13

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (6, y)

d = \sqrt{(6+2)^2+(y-7)^2}, that is

d = \sqrt{8^2+(y-7)^2} = 10

\sqrt{64+(y-7)^2} = 10 ← square both sides

64 + (y - 7)² = 100 ( subtract 64 from both sides )

(y - 7)² = 36 ← take the square root of both sides

y - 7 = 6 ( add 7 to both sides )

y = 13

Find the y-intercept and the slope of 12x-4y=7
den301095 [7]

Answer:

The slope is 3 and the y intercept is -7/4

Step-by-step explanation:

We need to get the equation in the form

y = mx+b where m is the slope and b is the y intercept

12x - 4y =7

Subtract 12x from each side

12x-12x -4y = -12x +7

-4y = -12x+7

Divide each side by -4

-4y/-4 = -12x/-4 +7/-4

y = 3x + -7/4

The slope is 3 and the y intercept is -7/4

A volcanic cone has a diameter of 300 meters and height of 150 meters. What is the volume of the cone?
marusya05 [52]
So a diameter is twice the radius
The formula is:
V = π(r^2)(h/3)
the half of 300 is 150, so the radius is 150
V = π(150^2)(150/3)
V = π(22500)(50)
V is about <span>3534291.74</span>
