Answer: 11 in.

Step-by-step explanation:

Given

The volume of the cylindrical vase is $216\ in^3$

Inside diameter is $d=5\ in.$

$(\text{radius is given by }r=\dfrac{d}{2})$

Suppose, h is the height of the vase

Volume is given by

$V=\pi r^2h$

Insert the values

$\Rightarrow 216=\pi \times 2.5^2\times h\\\\\Rightarrow h=\dfrac{216}{6.25\times 3.142}\\\\\Rightarrow h=10.999\approx 11\ in.$

Thus, the height of the vase is $11\ in.$

Triple my number add six and subtract my number twice I get my number plus three

liberstina [14]

Let the number be x.

Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3

So, combining these into an equation, we get:
3x + 6 - x - x = x + 3

If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3

Therefore, this is a false statement.

What is an equation in point slope form for the line that passes through the points (-1, 4) and (3, -4)

Nezavi [6.7K]

So the point-slope form looks like (y-y1) = m(x-x1)
So the first thing we should do is solve for m. We can do this using the slope formula (y1-y2)/(x1 - x2)

(-4 - 4)/(3 - -1) = -2

So our slope is -2. Then plug in any order pair for y1 and x2

So a possible solution is y - 4 = -2(x + 1)
Hopes this helps!

Which of the following equations has the same solutions as the equation 3x+2y=-12? Check all that apply.

grigory [225]

ANSWER

$B,C,E \: and \: F$

EXPLANATION

The given equation is
$3x + 2y = - 12$

The solution to this equation can be found by making y the subject.

$\Rightarrow \: 2y = - 3x - 12$

$\Rightarrow \: y = - \frac{3}{2} x - 6$
This equation has infinitely many solution. Any real value we choose for x, there is a corresponding y-value.

To find which of the given options also has the same solution, we make y the subject.

A

$3x - 2y = 12$

$\Rightarrow \: - 2y = - 3x + 12$

$\Rightarrow \: y = \frac{3}{2} x - 6$

This is not the same as the given equation.

B

$- 3x - 2y = 12$

$\Rightarrow \: - 2y = 3x + 12$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This solution is the same as the one given.

C.
$15x + 10y = - 60$

$\Rightarrow \: 10y = - 15x - 60$

$\Rightarrow \: y = - \frac{15}{10} x - \frac{60}{10}$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This is the same as the above solution.

D.
$6x + 2y = - 12$

$\Rightarrow \: 2y = - 6x - 12$

$\Rightarrow \: y = - 3 x - 6$

This is not the same as the one given.

E.

$6x + 4y = - 24$

$\Rightarrow \: 4y = - 6x - 24$

$\Rightarrow \: y = - \frac{6}{4} x - \frac{24}{4}$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This is the same as the one given.

F.

$1.5x + y = - 6$

$\Rightarrow \: y = - 1.5x - 6$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

Thus is the same as the one given.

G.
$x + \frac{2}{3} y = - 12$

$\Rightarrow \: \frac{2}{3} y = - x - 12$

$\Rightarrow \: y = - \frac{3}{2} x - 12 \times \frac{3}{2}$

$\Rightarrow \: y = - \frac{3}{2} x - 18$

This is not the same as the one given.
