Answer:  3.75 per shift

Step-by-step explanation:

Given : The amount earned by laundry = 12 dollars / hour

Since 1 dollar = 4 quarters.

Then, amount earned per hour=4\times12=48 quarters per hour.

    [By unitary method]

The time period for each shift = 75 minutes

Since 1 hour = 60 minutes

Then , 1 minute =\dfrac{1}{60} hours     [By unitary method]

Now, 75 minutes =75\times\dfrac{1}{60}=1.25 hours

Now, the total amount earned from each shift will be:-

1.25\times48=60 quarters

Now , the cost of laundry= 12 quarters/load

The cost of load after increment = 16 quarters

Then, the number of loads can be washed :-

\dfrac{\text{Total amount earned from each shift}}{\text{Cost of load after increment}}\\\\=\dfrac{60}{16}=3.75

Hence, number of loads of laundry = 3.75 per shift

What is 2/3 multiplied by 3/4 simplified? I need step by step to get answer.
Masteriza [31]
You start with the top number of each fraction and multiply them. So 2x3=6. Next you take the bottom number and multiply. So 3x4=12. That would give you a fraction of 6/12. 6 is half of 12 so 6/12 simplified is equal to 1/2. Hope this helps!

The snow is now 52 inches deep. If this was a 77% decrease, what was the initial depth? What equation can help you find this?
IrinaVladis [17]

Answer:

The required equation is:

0.23x = 52

Hence, option A is true.

Step-by-step explanation:

Given

Let 'x' be the initial depth

The snow is now 52 inches deep and it is a 77% decrease.

Let the initial 'x' depth be represented as 100%.

x → 100%

Given the current 52 inches is a 77% decrease. So, we need to decrease the 77/100 or 0.77 from the initial depth, so

[100% - 77%] of x = 52

[100/100 - 77/100] × x = 52

[1 - 0.77] × x = 52

0.23x = 52

Therefore, the required equation is:

0.23x = 52

Hence, option A is true.

=>πr^2= 286 cm^2

=>r^2= 286÷π

=>r= √286÷π

: 9.54. m

circumference=2πr

=> circumference=2×π×9.54
