NNADVOKAT [17]

Answer: Fraction of paint used for bird  house = \dfrac14

Step-by-step explanation:

Let quantity of the total paint be 1.

Given:  Fraction of paint to book shelf = \dfrac38

Fraction of Paint to leg = \dfrac14

Fraction of Paint left = \dfrac18

Let x= fraction of paint used for bird house.

Total paint = \dfrac38 +\dfrac 14+\dfrac18+x=1

\Rightarrow\ \dfrac{3+2+1}{8}+x=1\\\\\Rightarrow\ \dfrac{6}{8}+x=1\\\\\Rightarrow\ x=1-\dfrac68\\\\\Rightarrow\ x=\dfrac{2}{8}=\dfrac14

So, Fraction of paint used for bird  house = \dfrac14

Please help me with math
gogolik [260]

Answer:

part one:

6 3

22 1

30 0

part two:

0.50*s+4*a=15

Step-by-step explanation:

part one:

firstly:

6 individual songs cost 6*0.50= 3 dollars

she has 15 dollars so after downloading 6 individual songs that cost 3 dollars together

it means that she has only 15-3=12 dollars to download full albums

so 12/4=3 albums

because 4 dollar cost one album and with 12 dollars she can buy just 3 albums

secondary:

she downloaded 1 album

and one album cost 1*4=4 dollars

she has 15 dollars ,after buying 1 album

she has 15-4=11 dollars

so she can download 11/0.50=22 individual songs

so she can download 22 individual songs.

the last one:

she downloaded 30 individual songs

that all together cost 30*0.50=15 dollars

but she has 15 dollars at all so she cant buy any album because she spent all her money in individual songs.

because 15-15=0 money left

part two:equation

0.50*s+4*a=15

5/6 - 2/3 divide by 4/5
ollegr [7]

Answer:

5/24

Step-by-step explanation:

Start with the first part of the probelm 5/6 - 2/3

You need to find a common denominator of 6 and 3

common denominator= 6

so change 2/3 to 4/6

now you can subtract the top values

5/6-4/6

5-6=1

keep the denominator the same

= 1/6

Now divide 1/6  by 4/5

to divide you are going to multiply by the reciprocal so instead of 4/5 we are going to flip it to 5/4

1/6 x 5/4

5x1=5 and 6x4=24

= 5/24
