If 43 of the 148 reams of paper purchased by a department are used, what is the percentage that remains?
Wewaii [24]
100%/x%=148/43
<span>(100/x)*x=(148/43)*x       - </span>we multiply both sides of the equation by x
<span>100=3.44186046512*x       - </span>we divide both sides of the equation by (3.44186046512) to get x
<span>100/3.44186046512=x </span>
<span>29.0540540541=x </span>
<span>x=29.0540540541

</span>now we have: 
<span>43 is 29.0540540541% of 148</span>

10. Suppose you earn $7.25 per hour working part-time for a florist. What is the minimum number of hours you must work to earn a
UNO [17]
To make it like a simple, I'll make an equation. Let x be the number of hours because x represents unknown and we don't know the hours. Then your per hour is $7.25 right? so it would be x7.25. You want to know how many hours you will work so you can earn $125. The equation is simple as this x7.25 = 125.
All you have to do is divide the equation by 7.25 because that's your per hour.
It will look like this, <u>x7.25</u> = <u>125</u>   then the answer would be 17.24 hours.

the forecast calls for a 30% chance of snow today and a 40% chance of snow tomorrow. what are the chances it will rain two days
egoroff_w [7]

Answer:

The chances it will rain two days in a row is 12%

Step-by-step explanation:

The forecast calls for a 30% chance of snow today

So, chance of snowfall today = 30% = 0.3

A 40% chance of snow tomorrow.

So, chance of snowfall tomorrow= 40% = 0.4

The chances it will rain two days in a row = 0.4  \times 0.3

                                                                    = 0.12  

So, percent  it will rain two days in a row = 0.12 \times 100 = 12\%

Hence the chances it will rain two days in a row is 12%
