She spent $12 on notebooks, and she bought six notebooks.
12/6=2
Each notebook costed $2.
Answer:
$29.50
Step-by-step explanation:
First we need to find the tip
tip = pre tax bill * 10 %
tip = 25 * .10
tip =2.5
Next we need to find the tax
tax = pre tax bill * 8%
tax = 25 * .08
tax =2
Final bill = pre tax bill + tax + tip
Final bill = 25 + 2 + 2.5
=29.50
Answer:
<h2>The domain is all real values of x except

.</h2>
Step-by-step explanation:
The function,
.
g(x) = 5x - 4.
Hence, (f circle g) (x) =
.
We need to find the domain of (f circle g) (x) .
The domain means the set of values of x, for which we will get a real value of (f circle g) (x).
The function will not give a real value when, 5x - 4 = 0 that is
.
Hence, the domain of the function will be all real values of x rather than
.
Answer:
The area of the bulletin board is 30 square foot.
Step-by-step explanation:
A bulletin board can be covered completely by 30 square pieces of paper without any gaps or overlaps.
If each piece of paper has side length of 1 foot so the area of each paper is 1 ft x 1 ft = 1 square foot.
There are 30 pieces of paper needed to completely cover the bulletin board, so 30 pcs of paper with an area of 1 square foot is equal to 30 square feet. The area of the bulletin board is 30 square foot.
