16 3/4 hours in two days plan to work 12 3/4 hour the next two days. How many hours will u total on your time sheet for these 4
sergiy2304 [10]

let's firstly convert the mixed fractions to improper fractions and then add up all four days.

\bf \stackrel{mixed}{16\frac{3}{4}}\implies \cfrac{16\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{67}{4}}~\hfill \stackrel{mixed}{12\frac{3}{4}}\implies \cfrac{12\cdot 4+3}{4}\implies \cfrac{47}{4} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{all 4 days summed up}}{\cfrac{67}{4}+\cfrac{47}{4}}\implies \cfrac{67+47}{4}\implies \cfrac{114}{4}\implies \cfrac{57}{2}\implies 28\frac{1}{2}

Clarisa's annual gross pay as an account manager is $54,000. If the graduated state tax rate is 1% for the first $5,000 and 3% f
Hoochie [10]

Answer:

Total taxes = $1,520

Step-by-step explanation:

We have two separate calculations for the taxes:

The tax rate for the first $5,000 of Clarisa's gross pay is 1%, so the amount of tax paid in this case is

1% * 5000 = $50

The tax rate for the amount of value over $5,000 (that is, 54,000 - 5,000 = 49,000) is 3%, so the amount of tax is:

3% * 49,000 = $1,470

So, the total amount deducted for state taxes is:

Total taxes = 50 + 1470 = $1,520

The graph below represents the linear equation y = one-half x minus 3. On a coordinate plane, a line goes through (0, negative 3
mamaluj [8]

Answer:

(C) (2, -2)

Step-by-step explanation:

Given the linear equation: y=\dfrac12x-3

A second linear equation is given by the table:

\left|\begin{array}{c|cccccc}x&-1&0&2&3\\y&1&0&-2&-3\end{array}\right|

Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.

Therefore if:

y=\dfrac12x-3;$and $\\y=-x\\Then:\\\dfrac12x-3=-x\\\dfrac12x+x=3\\\dfrac32x=3\\3x=6\\x=2

Recall: y=-x

Therefore: y= -2

Therefore, a solution to the system of equations is (2, -2)
