50% = 30

20% = 12

_____________________

a = 35

b = 105

c = 140

____________________________

15 is 30% of 50.

_____________________________

10.

The punch recipe contains 25% lemonade:

24/6 = x/100

x=1/4 x 100 = 25%

_____________________________

Number of items checked = 300

Defective items = 3%

Number of defective items =

Number of defective items = 9

Number of items worked = Total items - Number of defective items

Number of items worked = 300 - 9 = 291

291 items of checked items worked.

The initial value is 21 and rate of change is 16 pages per week

<em><u>Solution:</u></em>

Given that After writing part of his novel, Thomas is now writing 16 pages per week

After 4 weeks, he has written 85 pages.

Given that assume the relationship to be linear

Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + c

y = mx + c

where "y" is the number of pages written after 4 weeks

x = 4 weeks and m = 16 pages

Therefore,

85 = 16(4) + c

85 = 64 + c

c = 85 - 64

c = 21

Therefore, initial value is 21 and rate of change is 16 pages per week

What can you conclude about 3/5 and 60/100 if you know 3/5 is equivalent to 6/10 and 6/10 is equivalent to 60/100

labwork [276]

First we check whether $\frac{3}{5}$ is equivalent to $\frac{6}{10}$

$\frac{3*2}{5*2}$ = $\frac{6}{10}$

Both top and bottom are multiplied by 2 to get $\frac{6}{10}$

So they are equivalent fractions.

Now we check whether $\frac{6}{10}$ is equivalent to $\frac{60}{100}$

$\frac{6*10}{10*10}$ = $\frac{60}{100}$

Both top and bottom are multiplied by 10 to get $\frac{60}{100}$

So they are equivalent fractions.

$\frac{3}{5}$ = $\frac{6}{10}$ = $\frac{60}{100}$

Hence we conclude that they are equivalent fractions.
