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

Area of the base

18= Area of the base

Hence final answer is 18 square centimetres.

Answer:

$\frac{12}{55}$

Step-by-step explanation:

To divide fractions, here are your steps:

1) Invert the fraction you are dividing by.

2) Multiply the numerators and denominators.

3) Simplify if necessary.

$\frac{3}{5}$ / $\frac{4}{11}$

$\frac{3 * 4}{5 * 11}$ = $\frac{12}{55}$

Cannot be further simplified.

What is the answer?<br> xy = 30<br> and x + y = 18

drek231 [11]

from second equation y = 18-x so:-

x(18 - x) = 30

x^2 - 18x + 30 = 0

x = 16.14, 1.86

when x = 16.14 y = 18-16.14 = 1.86

when x = 1.86, y = 16.14

so one variable = 16.14 and the other = 1.86 Answer

sarah used 3/4 pound of blueberries to make 1/2 cup of jam. how many pounds of blueberries would she need to make a cup of jam?

Ksenya-84 [330]

Answer: She needed $1\frac{1}{2}\text{ pounds of blueberries}$ to make a cup of jam .

Step-by-step explanation:

Since we have given that

Sarah used $\frac{3}{4}$ pound of blueberries to make $\frac{1}{2}$ cup of jam.

As we need to find the number of pounds of blueberries she would need to make a cup of jam.

So, we will use "Unitary Method":

$\text{For }\frac{1}{2}\text{ cup of jam},\\\\\text{ she need }\frac{3}{4}\text{ pound of blueberries }\\\\\text{ For 1 cup of jam}.\\\\\text{She need }=\frac{3}{4}\times 2=\frac{3}{2}=1\frac{1}{2}\text{ pounds of blueberries }$

Hence, She needed $1\frac{1}{2}\text{ pounds of blueberries}$ to make a cup of jam .
