Determine if -81.42 is rational or irrational. If it is rational, write the number as a ratio of two integers.
Answer:
-81.42 is a rational number
Step-by-step explanation:
[tex] - 81.42 \\ \\ = - \frac{8142}{100} \\ \\ = - \frac{8142 \div 2}{100 \div 2} \\ \\ = - \frac{4071}{50} \\ \\[/tex]
Answer: It is a rational number.
A rational number is a number that can be represented as a fraction.
The fraction can be: [tex]- \frac{4071}{50}[/tex] because:
[tex]-\frac{81.42}{100}[/tex] ÷ 2 = [tex]\frac{40.71}{50}[/tex]
The answer is yes, it is rational.

Step-by-step explanation:
just a guess C;
The point that satisfies both the inequalities is (0, 3).
Correct option is (C).
What is Inequality?Inequalities are mathematical formulas in which neither side is equal.
As per the given data:
We are given two inequalities, and we have to find out whether the points that are given in the options are satisfying the solution set of the given inequalities or not.
The inequalities are as follows:
x + y > 2
4x + y ≥ -1
For option (A). (2, 0)
Substituting the points in the given inequalities.
2 > 2 and 8 ≥ -1
Hence, this is incorrect.
For option (B). (0, 2)
Substituting the points in the given inequalities.
2 > 2 and 2 ≥ -1
Hence, this is incorrect.
For option (C). (0, 3)
Substituting the points in the given inequalities.
3 > 2 and 3 ≥ -1
Hence, this is correct.
For option (D). (0, -1)
Substituting the points in the given inequalities.
-1 > 2 and -1 ≥ -1
Hence, this is incorrect.
Hence, The point that satisfies both the inequalities is (0, 3).

Find the distance between -7, -3 2/3 on a number line.
Answer:
3 and 1/3 because 7 minus 3 and 1/3 equals 3 2/3 or you could also do 3+3=6 and 2/3+1/3=1 and 1+6=7
The distance between -7 and -3 2/3 on the number line is 3 1/3
How to determine the distance between the numbers?The numbers are given as:
-7 and -3 2/3
Calculate the absolute difference between both numbers
d = |-7 + 3 2/3|
Evaluate the difference
d = | 3 1/3|
Evaluate the absolute value expression
d = 3 1/3
Hence, the distance between -7 and -3 2/3 on the number line is 3 1/3

Mario had 12 apples and gave away x apples. Luigi had 26 apples and gave away three times as many apples as Mario did. How many apples did Mario give away if they had the same number of apples left?
Answer:
7 Apples
Step-by-step explanation:
For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.
Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x
Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x
Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):
Mario Luigi
12-x = 26-3x
12-x=26-3x
Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:
12-x-12=26-12-3x
-x=14-3x
-x+3x=14-3x+3x
2x=14
2x/2=14/2
x=7
Mario gave away 7 apples.

Kim works as a server in a restaurant. She is serving the table where a group of her friends are eating. Her friends always tip 15%. If the cost of the meal is $23.60, how much of a tip will Kim earn?
if the bill was $23.60, and the tip was 15%, kim will earn $3.54. the overall total of the meal would be $27.14 :)
Anwser will be $3.54
15% = .15 ( to convert percent to decimal, change the % to . and move the decimal two places to the left)
23.60 * .15 = 3.54

Write an equation for a line that is parallel to 9x + 3y = 8 and passes through the point (-1, -4).
Answer:
y = -3x - 7
Step-by-step explanation:
turn into slope-intercept form:
9x + 3y = 8: subtract 9x to isolate y
3y = -9x + 8: divide by three to isolate again
y = -3x + 8/3 (line): Substitute y and x and replace 8/3 with b
-4 = -3(-1) + b: distribute
-4 = 3 +b: isolate b by subtracting 3
-7 = b
Substitute for b in original equation
y = -3x - 7
Answer:
y=-3x-7
Step-by-step explanation:
First you need to change the equation to slope intercept form. so the equation becomes y=-3x+8/3. now you change it point slope, y-y1=m(x-x1), y--4=-3(x--1), which also becomes y+4=-3(x+1), now you multiply. -3 times x and 1 which makes the equation, y+4= -3x+-3, then subtract from each side since its a positive number. so now the equation y= -3x-7

It costs $11.50 to rent a canoe and $5.50 to use the canoe for an hour. You have $28. Write an equation that represents the number h of hours you can rent the canoe
Answer:
(28 - 11.5) ÷ 5.5
Step-by-step explanation:
So let's examine this question.
We have already payed $11.50 the rent the canoe, so we have $16.50. Divide that by $5.50, and you get 3. So, 3 hours.
Now for the expression.
You start out with $28. You subtract $11.50 from it because it is being used to rent the canoe. You then divide your answer by $5.50 to determine how many hours you can use the canoe for.
Hmm.
(28 - 11.5) ÷ 5.5 = h
(28 - 11.5) ÷ 5.5 = 3
