What is three -fifths of thirty

Answers

the answer is 18. 30 divided by 5 is 6. so 3 times 6 is 18.

what is three-fifths of thirty?
well we can look at this way easier by setting them both up with fractions
and since we don't know the numerator (the top number) for thirty we just put x in its place:)
3 x
----- -----
5 30

all we need to do is figure out what we multiplied by 5 to get 30
well lets just divide 30 by 5 ...
30 ÷ 5 = 6
so that means that we multiplied 6 to get 30
in order to get x we do the same to the top number of 3/5 so (3)
3 x 6 = 18 and thats what equals x!
so 3/5s of 30 is 18!
Answer = 18
hope this helps!

(10 points)A certain regular polygon has sides of length 10 cm; its apothem is 12.1 cm. The polygon’s area is 484 cm². How many sides does the polygon have

Answers

There is a mathematical formula which relates these quantities, given by:

$A= (P* a)/(2)$

Using this, we have:

$A= (P* a)/(2) \n 484= ((10n)* 12.1 )/(2) \n \boxed {n=8}$

A student bought a juice pouch for $2.50 and 3 bags of chips . The total cost was $5.05 write and solve an equation to determine the cost of a bag of chips

Answers

You have to subtract $2.50 and $5.05 then you divide that with 3 and you should get $0.85

Do 5.05 minus 2.50 and your would get 2.55 then you would divide that by 3 and you would get 85 cents per bag of chips
