lidiya [134]

Answer:

500 shots

Step-by-step explanation:

the question is 8% of what number is 40?

we can use this proportion: is/of = %/100

let 'g' = number of goals

40/g = 8/100

cross-multiply to get:

8x = 4000

x = 500

1/3 cup of flour is used to make 5 dinner rolls. how many cups of flour are needed to make 3 dozen dinner rolls

MAVERICK [17]

F = Cup of flour

D = Dinner roll(s)

12 = A dozen

36 = Three dozen

---------

1/3 * F = 5 * D

n * F = 36 * D

------

$\frac { 1 }{ 3 } F=5D\\ \\ 3\cdot \frac { 1 }{ 3 } F=3\cdot 5D\\ \\ F=15D$

$nF=36D\\ \\ n=\frac { 36D }{ F }$

This means that...

$n=\frac { 36D }{ 15D } \\ \\ n=\frac { 36 }{ 15 } \\ \\ n=\frac { 3\cdot 12 }{ 3\cdot 5 } \\ \\ n=\frac { 12 }{ 5 } \\ \\ n=\frac { 10 }{ 5 } +\frac { 2 }{ 5 } \\ \\ n=2+\frac { 2 }{ 5 }$

And this means that two cups of flour and 2/5 of a cup of flour are required to make 3 dozen dinner rolls.
