A pencil holder shaped like a triangular prism the height of the pencil is 12cm and the volume is 216cm what is the area of the

mamaluj [8]

Given that Volume of triangular prism = 216 cubic centimetre

Given that Height of the pencil = 12 centimetre

Now we have to find the area of the base of the prism means find the area of triangular part.

Volume of triangular prism is given by formula:

Volume of triangular prism = (Area of base) x (Height of the prism)

now plug the given values

216= (Area of the base) x 12

$\frac{216}{12}=$ Area of the base

18= Area of the base

Hence final answer is 18 square centimetres.

What are two numbers I can use to multiply to 4, but also i can add those numbers to equal 2? Any integers are okay.

LekaFEV [45]

No 'real' numbers can do that job.
The two numbers are complex.

They are ...

<em>1 + i √3</em>
and
<em>1 - i √3</em> .

Paul has $20,000 to invest. His intent is to earn 11% interest on his investment. He can invest part of his money at 8% interest

hjlf

Answer:

In the 8% option , $5,000 should be invested

In the 12% option, $15,000 should be invested

Step-by-step explanation:

Let’s start with the total return.

Since the total return expected is 11%, the amount expected to be returned will be;

11/100 * 20,000 = $2,200

Now, let the amount invested at 8% interest be $x while the amount invested at 12% interest be $y

Mathematically;

x + y = 20,000 ••••••(i)

Now let’s work with the interest part;

On the 8% part, amount of interest expected is 8/100 * x

on the 12% part, amount of interest expected is 12/100 * x

8% of $x + 12% of $y = 2,200

Writing this fully mathematically, we have;

(8/100 * x) + (12/100 * y) = 2,200

8x/100 + 12y/100 = 2,200

Multiply through by 100

8x + 12y = 220,000 ••••••(ii)

Now we have two equations to solve simultaneously;

x + y = 20,000

8x + 12y = 220,000

From i, x = 20,000-y

Substitute this into ii

8(20,000-y) + 12y = 220,000

160,000-8y + 12y = 220,000

4y = 220,000 - 160,000

4y = 60,000

y = 60,000/4

y = $15,000

x = 20,000 -y

x = 20,000 - 15,000

x = $5,000
