Answer:
Maxine has $1,651.20 remaining after state income tax is deducted from her paycheck.
Step-by-step explanation:
If Maxine earns $ 21.50 an hour and works 40 hours per week, each week she earns a total of $ 860 (40 x 21.5). Since she collects every 2 weeks, her pre-tax salary is $ 1,720 (860 x 2). But the state discounts an income tax of 4%, with which the money that she effectively receives every two weeks is $ 1,651.20 (1720 - (1720 x 0.04).
Answer: 56.4102564% decrease
Explanation: First determine whether the number is increasing or decreasing. Since it changes from 39 to 17, it's going down so it's decreasing.
Now to find the percent decrease,
we divide the amount of change by the original number.
The amount of change is the difference between the two numbers
which in this case is 39 - 17 and the original number is 39.

39 - 17 is 22 so we're left with
which gives us 56.4102564
Remember however that our problem is asking for a <em>percent</em>, not a decimal. So we need to write 56.4102564 as a percent by moving the decimal point 2 places to the right to get 56.4102564.
So when a number changes from 39 to 17, it has decreased by 56.4102564%.
Three numbers less than 2, but greater than -1 are:
- 1.5 (I don't know if that counts as a number specifically)
Answer:
The surface area of the given pyramid is 112
.
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base = 
= 
= 16
Area of its base = 16 
Area of one of its triangular surface =
x base x height
=
x 4 x 12
= 2 x 12
= 24 
Area of all its four triangular surfaces = 4 x 24
= 96 
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112 
The surface area of the given pyramid is 112
