3a. Jackson's gross pay for 40 hours is
(40 h)×($12.20/h) = $488.00
3b. An equation for Jackson's pay could be
372.10 = h×12.20
This can be solved for h by dividing by 12.20
372.10/12.20 = h = 30.5
Jackson worked 30.5 hours last week.
3c. The total of hours shown is
(8) + (7 1/4) + (8 1/2) = (8 +7 +8) +(0.25 +0.50) = 23.75
The number of hours missing is the difference between this number and the hours found in part (b).
30.50 - 23.75 = 6.75
There are 6 3/4 hours missing from Jackson's time sheet for last week. This is less than a full day's work, so seems reasonable.
_____
Of course, you know the decimal - fraction conversions:
1/4 = 0.25
1/2 = 0.50
3/4 = 0.75
Answer:
298
Step-by-step explanation:
Answer:
The answer is b
Step-by-step explanation:
Answer: 3
Step-by-step explanation:
Set them equal because they are the same so 15x+5=16x+2 so x+2=5 so x=3
Definition
Functions have zeros or x-values that generate function values equal to zero.
Equations have roots or solutions that can be substituted into the polynomial in order to generate a value equal to zero.
Given:
![f(x)\text{ = -}\frac{1}{3}\sqrt[]{x}\text{ + 3}](https://tex.z-dn.net/?f=f%28x%29%5Ctext%7B%20%3D%20-%7D%5Cfrac%7B1%7D%7B3%7D%5Csqrt%5B%5D%7Bx%7D%5Ctext%7B%20%2B%203%7D)
To convert this to an equation, we set f(x) equal to zero i.e
The resulting equation is:
![-\text{ }\frac{1}{3}\sqrt[]{x}\text{ + 3 = 0}](https://tex.z-dn.net/?f=-%5Ctext%7B%20%7D%5Cfrac%7B1%7D%7B3%7D%5Csqrt%5B%5D%7Bx%7D%5Ctext%7B%20%20%20%2B%203%20%3D%200%7D)
