Thank you for posting your question here. Below is the solution:
ark worked 5 2/3 + 9 1/3 = 15 hours. 8 3/5 + 9 2/5 = 18 hours + 9 hours.
<span>15 + 18 + 9 = 42 hours worked @ $6.55 per hour </span>
<span>40 hours regular pay and 2 hours overtime. </span>
<span>Over time is 1 1/2 X $6.55 = $9.83 per hour X 2 hours overtime worked = $19.65 in over time . </span>
<span>40 hours @ $6.55 = $262.00 + $19.65 = $281.65.Gross pay </span>
<span>Chris. </span>
<span>5 1/2 + 9 1/2 = 15 hours </span>
<span>8 4/5 + 5 1/5 = 14 hours </span>
<span>14 + 15 = 29 hours worked. @ $9.65 per hour = $279.85 Gross pay </span>
The required expression is 100 - 0.2w
Step-by-step explanation:
Given,
Amount of radioactive substance = 100 mg
The substance decreases by 20% each week.
To find the remaining amount of the in w weeks.
Now,
Each week 20% = 0.2 of the substance will be decreased.
So, in w weeks 0.2×w of the the substance will be decreased.
Hence,
The remaining substance = 100 - 0.2w
(simplest form)
9/20 = 45% as a fraction
3/25 = 12% as a fraction
Hope this helps!!!
Answer:
(simplified)
(in terms of pi)
Step-by-step explanation:
Since the salsa jar is basically a cylinder, to solve this we are using the formula for the volume of a cylinder:
where
Is the volume of the cylinder (salsa jar)
is the radius of the cylinder (salsa jar)
is the height of the cylinder (salsa jar)
We know from our problem that height of the full salsa jar is 10 centimeters; we also know that that there are only 4 centimeters of salsa left in the salsa jar. So, to find the the height of the missing salsa, we just need to subtract the height of the salsa from the height of the full salsa jar: 
. Since the radius of the salsa jar never changes, 
.
Now we can replace the values in our volume formula to find how much salsa is missing from the jar:
We can conclude that there are 471.24 cubic centimeters missing from the jar, or in terms of pi: 
.
