You need to find out how many pound of dirt they put in the 1st flower bed. 5/8+2/5+3/4. 1 pound = 16 ounces so what ever you get * 16 to get how ever many ounces. I hope this helped. :)

How do I figure out what 1/10 of 6000 is?

Answers

The way I like to figure out problems like this is to write it out like,

1/10 = x/6000
(One over ten equals x over 6000)

Then you find out how much you multiplied 10 by to get 6000. To do this you can divide 6000 by 10 getting 600. The rule "what you do to the bottom you have to do to top" in this equation. So since you multiplied the bottom by 600 you have to multiply the top by 600 as well. 600 times 1 is just 600.

So your answer is, 600 is 1/10 of 6000.

Hope this helps and isn't too confusing.

Find the missing side of the triangle the base of the triangle is 3 and 1/4

find the missing side

SHOW WORK

Answers

area=(1/2)bh
b=legnth of base
h=legnth of height

we are given
b=3 and 1/4
area=12 and 2/5

covert everybody to improper fraction

b=3 and 1/4=3+1/4=12/4+1/4=13/4
area=12 and 2/5=12+2/5=60/5+2/5=62/5

area=(1/2)bh
62/5=(1/2)(13/4)h
62/5=(13/8)h
times 8/13 both sides (13/8 times 8/13=104/104=1)
496/65=h
