The price for a new car, without sales tax, is
$18,900. The buyer must also pay a 5% state
sales tax. What is the cost of the car includ-
ing the sales tax?
Answers
Answer:
Step-by-step explanation:
18900 divided by 10 = 1890
1890 divided by 2 is 945
945 is 5 percent of 18900
18900 + 945 = 17955
Answer = 19845
5% of 18,900
= 945
The price for the car
= $18,900
$18,900 + 5
= $19,845

find the slope and y- of the table
Answers
Answer:
y = (3/2) x +6
Step-by-step explanation:
The y-intercept is clearly at y = 6 point (0, 6) of the table.
The slope can be calculated using any two pairs, for example (-4,0) and (-2, 3)
slope = (y2 - y1)/(x2 - x1) = (3 - 0) / (-2 + 4 ) = 3/2
Then the equations of the line in slope y-intercept form is:
y = (3/2) x +6

The original price for a jacket is $124.95. It is on sale for 20% off. Which of the following gives the best estimate of the savings?
Answers
Answer:
24.99
Step-by-step explanation:
We first must figure out the current price of the jacket, we need to multiply the original price (124.95) times .80 (1.00 - .20). Doing so we get a total of 99.96. In order to find the savings, we subtract the original price by the new price. 124.95-99.96 = a savings of 24.99
Answer:
You would be saving 24.99 dollars
Step-by-step explanation:
Find 20% of 124.95 using P(percentage in decimal form) times X(original number) and you should have your answer.

Step-by-step explanation:
The processors that power computers are able to perform calculations quickly, and the calculations are performed using Boolean algebra. People generally solve math problems using a base-10 number system. Boolean algebra relies on base-2 math, in which all numbers are represented using ones and zeros.
In addition to calculating basic math problems, however, computers also use Boolean logic. This logic, which is rooted in discrete mathematical principles, allows computers to solve problems that require making logical decisions. Boolean algebra and logic combine to make sophisticated devices; self-driving cars, for example, use the input calculated from digital cameras to make decisions about how to navigate.

Answers
Answer:
Step-by-step explanation:
Since we are not given the value of P, |Q|, R and S, we can as well assume values for them for the sake of this question.
Let P = 5, |Q| = 6, R =7 |S| = 2
Note that since Q and S are in modulus sign, they can return both positive and negative values.
P+Q = 5 + 6 (note that the positive value of Q is used since we need the greatest value of P+Q)
P+Q = 11
Hence the greatest value of P+Q is 11
For the least value of P+Q, we will use the negative value of Q as shown
P+Q = 5+(-6)
P+Q = 5-6
P+Q = -1
Hence the least value of P+Q is -1
Similarly:
R+S = 7 + 2 (note that the positive value of S is used since we need the greatest value of R+S)
R+S = 9
Hence the greatest value of R+S is 9
For the least value of R+S, we will use the negative value of S as shown
R+S = 5+(-2)
R+S = 5-3
R+S = 2
Hence the least value of P+Q is 2
NOTE THAT THIS ARE ASSUMED VALUES. ALL YOU NEED IS TO PLUG IN THE VALUES OF P, Q and R THAT YOU HAVE IN CASE THE VALUES DIFFERS.

Robin Hartman earns $600 per week plus 3% of sales over $6,500. Robin's week sales are $14,000. How much does Robin earn
Answers
Answer:
$825
Step-by-step explanation:
Given that :
Weekly earning = $600 plus 3% of sales over $6500
If weekly sales = $14000
How much will Robin earn
Robin's earning will be:
Flat weekly pay + 3% of amount over 6500
$600 + 3%(weekly sales - 6500)
$600 + 0.03(14000 - 6500)
$600 + 0.03(7500)
$600 + $225
= $825

D. A whiteboard is meter long and has an area of 1 square meter.
How wide is the whiteboard?
Answers
Answer:
The answer is below
Step-by-step explanation:
A) Given that the area of the square a square foot = 1 ft², the width = 1 foot
Area = length × width
1 ft² = length × 1 ft
Length = 1 ft²/ 1 ft = 1 ft
B) Given that length of wrapping paper = 1 yd, width = 1 yd.
The area of the paper = length × width = 1 yd × 1 yd = 1 yd²
C) Given that the area of the wetland is a square mile = 1 mile², the length = 1 mile
Area = length × width
1 mile² = 1 mile × width
width = 1 mile²/ 1 mile = 1 mile
D) Given that the area of the square a square meter = 1 m², the length = 1 meter
Area = length × width
1 m² = 1 m × width
width = 1 m²/ 1 m = 1 m
