Answer:
There are 77 s
Step-by-step explanation:
You can calculate this by a series of flips and operation changes.
Step 1 - Change 22 into a fraction
Step 2 - Flip the operation, in this case, it will be from division to multiplication:
Step 3 - Flip the second fraction
Step 4 - Multiply the two fractions together:
Step 5 - Divide the numerator by the denominator:
154 ÷ 2 = 77
So 22 has 77 s in it.
Hope this helps!

Answer:
Step-by-step explanation:
We are given the two functions:
And we want to find:
This is equivalent to:
By substitution:
Rearranging yields:
Combine like terms:
Hence:
For problem one she starts off earning 10.24 dollars per hour. She receives a raise of 1.60 dollars. So first you have to add both 10.24 and 1.60 together to find out how much more she is payed. 10.24+1.60=12.04. She works 22.25 hours. It would take forever to add 12.04 22 and a quarter times so you multiply them. 12.04*22.25=267.89. So she would earn 267.89 dollars from working 22.25 hours.
For problem two you would start off by dividing 3/4 (the amount of pizza) by 5 (the five people) because when you do this it will give you the equal amount of pizza that each person can have. You get 0.15 which is equal to 3/20. So each person will get 3/20 of the 3/4 of the pizza that are left. (To simplify it the answer is 3/20) you can check your work by doing 3*5 which is 15. Make this the numerator and it’s 15/20. 15/20=3/4.
For the third problem you start off by putting aside the .25 of an ounce. Take the 3 ounces and multiply it by the cost per ounce 3.56. 3*3.56=10.68. Now that you have figured out how much 3 ounces cost out that aside. Now for the .25 of an ounce. Since .25 goes into one four times you do 3.56/4. It’s 0.89. This is how much it costs per .25 of an ounce. After that you add 10.68+0.89. It’s 11.57. To finish the problem you have to subtract 11.57 from 20 dollars. 20.00-11.57=8.43. The teacher receives $8.43 in change.
