Answer 1

Answer:

The prism with the pentagonal base's volume is 585 cm³.

Step-by-step explanation:

Step 1:

The prism has a pentagonal base.

The volume of a prism with a pentagonal base, $V=(1)/(4) \sqrt{5(5+2 √(5))} a^(2) h.$

In the formula to determine the prism's volume, in the question, it is given that $(1)/(4) \sqrt{5(5+2 √(5))} a^(2)$ is equal to 45 cm².

Step 2:

So if we substitute $(1)/(4) \sqrt{5(5+2 √(5))} a^(2) = 45$ in $V=(1)/(4) \sqrt{5(5+2 √(5))} a^(2) h.$ we get,

$V=(1)/(4) \sqrt{5(5+2 √(5))} a^(2) h =$ $45h.$

The value of h for the given prism is 13 cm, so

$V = 45(13) = 585$ cm³.

The prism's volume is 585 cm³.

Help!!! I don’t get this :(

Answers

You have to use distributive property. Multiply the numbers outside of the parenthesis by the numbers inside. For example, you would multiply 0.4 by 2x first, then multiply it by 1/2. You should get two answers. Write them down in this form: first answer + second answer. Then do the same for the other side of the equal sign, but leave the - 4 alone.

four students spent $12 on school lunch .at this rate,find the amount 10 students would spend on the same school lunch

Answers

In order to solve this, we need to figure out how much ONE student spends.
$(12dollars)/(4students) = 3$ dollars per student.

If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
$10students* (3dollars)/(student) = 30dollars$

ok so you will multiply 12 times 10 or you could add 12 + 12+12+12+12+12+12+12+12+12 add them up and it will be $120
