The volume of the triangular prism is 54 cubic units.What is the value of x?
nadezda [96]

Answer:

x=3

Step-by-step explanation:

the volume of the prism with triangular base is 54 unit³

The base is a triangle with,  base i.e 4 units  and  height i.e x units

Also,  height of the prism = 3x

So, volume of the prism is,

And

,

Area_{Triangle}=\dfrac{1}{2}\times base\times Height_{Triangle}=\dfrac{1}{2}\times 4\times x=2x\ unit^2

Then,

V_{Prism}=2x\times 3x=6x^2

As the volume is given as 54 unit³, hence

6x²=54

x²=9

x=3

How to do this and the answers.
ANEK [815]

Answer:

I'm gonna estimate about 240 miles one way

Explanation:

You have a guide on the bottom right-hand corner of the map that tells you how many miles per that amount of distance. As you can see it is split off into tiles incremented by 30. What you do is take a ruler and measure that guide. For example, let's say the map is 9.5cm and the guide is 2cm per 60 miles. The next thing I would do is to measure the distance in centimeters of the physical map between point a and point b which is 8cm. Finally, I convert the centimeters into miles which is (8/2)*60 = 240.

Slope = 2/3, passing through (7,4). Write an equation for the line in point-slope form.
Marat540 [252]

Answer:

y - 4 = (2/3)(x - 7)

Step-by-step explanation:

(see attached for reference)

we are given slope, m = 2/3 and point (x₁, y₁) is (7,4)

y - y₁ = m(x - x₁)

substituting the given values into the general equation

y - y₁ = m(x - x₁)

y - 4 = (2/3)(x - 7)

Helooo someone please
Maurinko [17]

Answer:

B

Step-by-step explanation:

In this case the method of there being two of the same x values it is NOT a function. Because then there will be two points on top of each other resulting in it not passing the vertical line test on a graph.
