at least 13 all you have to do is take away 5 from 10 and divide 10 by .75

What is the volume of the following triangular prism?

Eva8 [605]

Answer:

$V=150cm^3$

Step-by-step explanation:

First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.

The area of the triangle is given by the formula:

$A_T=\frac{bh}{2}$

where b is the base: $b=4cm$ and h is the height: $h=5cm$

thus, in this case we have:

$A_T=\frac{(4cm)(5cm)}{2}\\ \\A_T=\frac{20cm^2}{2} \\\\A_T=10cm^2$

And now, the volume will be the area of the triangle multiplied by the length $l=15cm$ of the prism:

$V=A_T*l$

Substituting the known values:

$V=10cm^2*15cm\\V=150cm^3$

The volume in cubic centimeters is 150.

A set of 6 number cards contain the numbers 2, 5, 7, 8, 9, and 11. Which ratio is less than the ratio of odd number cards to tot

Tamiku [17]

Answer:

$Ratio = 2:3$

Step-by-step explanation:

Given

$Cards = \{2,5,7,8,9,11\}$

Required

Ratio of odd numbers to total

First, list out the odd numbers

$Odd = \{5,7,9,11\}$

The card has 4 odd numbers out of a total of 6.

So, the ratio is:

$Ratio = Odd : Total$

$Ratio = 4:6$

Divide by 2

$Ratio = 2:3$

<em>Hence, the ratio of odd to total is 2 to 3</em>
