Answer:
like real numbers, the arithmetic operations, such as addition, subtraction, multiplication and division are applicable to the rational numbers
All arithmetic operations such as addition, subtraction, multiplication, and division can be solved for rational numbers.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
A rational number is a number in form of p/q where p and q both will be integers.
Since p and q both are integers so we can multiply by other fractions for example (2/3) x (4/6).
We can divide by another integer for example (2/3)/4.
Hence "All arithmetic operations such as addition, subtraction, multiplication, and division can be solved for rational numbers".

-7 2/3 + -5 1/2+ 8 3/4 PLZZZZZ HELP ME!!!!!!!!!!!!!!
Answer:
-4.416 repeating
Step-by-step explanation:
Answer:
-53/12 or 4 5/12 either works
Step-by-step explanation:
Let's turn the mixed fractions into improper fractions.
-7 2/3 = -23/3
-5 1/2 = -11/2
8 3/4 = 35/4
Now we need to find Least Common Denominator.
12 is the LCD because
3*4 = 12 is for -23/3
2*6 = 12 is for -11/2
4*3 = 12 is for 35/4
Now you will multiply the improper fractions by the 2nd number.
[tex]-\frac{23}{3}*(\frac{4}{4}) = -\frac{92}{12} \\\\-\frac{11}{2}*(\frac{6}{6}) = -\frac{66}{12} \\\\\frac{35}{4}*(\frac{3}{3}) = \frac{105}{12}[/tex]
Now that they have the same denominators just put the numerators in the equation.
-92 + -66 + 105 = -53
-53/12 or -4 5/12
Hope this helps ya!
Review the graph of complex number z.
On a coordinate plane, the y-axis is labeled imaginary and the x-axis is labeled real. Point z is at (negative 6, 6).
What is the polar form of z?
6 StartRoot 2 EndRoot(cos(135°) + isin(135°))
6 StartRoot 3 EndRoot(cos(135°) + isin(135°))
6 StartRoot 2 EndRoot(cos(225°) + isin(225°))
6 StartRoot 3 EndRoot(cos(225°) + isin(225°))
9514 1404 393
Answer:
[tex]6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))[/tex]
Step-by-step explanation:
The angle to the point in the second quadrant is measured from the positive real axis (the x-axis). Second quadrant angles are between 90° and 180°, leaving the 135° choices as the only ones that make sense.
The magnitude of z is the root of the sum of the squares of its components:
|z| = √((-6)^2 +6^2) = 6√2
So, the polar form of z is ...
[tex]\boxed{6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))}[/tex]
this matches the first choice

Step-by-step explanation:
At a dinner, one meal cost $22 and a sales tax of $1.87 was added to the bill.
Answer:
5.61; 8.5 %
Step-by-step explanation:
Tax = $1.87 per $22 meal
For a $66 meal,
Tax = 66 × 1.87/22
Tax = 3 × 1.87
Tax = $5.61
=====
Tax rate = 1.87/22 × 100
Tax rate = 0.085 × 100
Tax rate = 8.5 %

Answer:
Jeandre is correct, and they are 2 units from zero
Step-by-step explanation:
The absolute value of 2 is 2, and the absolute value of -2 is 2. Absolute value is the real number without a sign. If you put both 2s, on the number line, they would be the same length from zero. by the way absolute value means that everything will be positive, for an example - |-1| it is going to be positive one now! how you can tell it is a absolute value is cause it will have lines imbetween the number (ex - |-3|)

For lunch, you have a choice of nachos or a fish sandwitch, green beans or french fries, strawberries or jello, and white or chocolate milk. Assuming you chose one of each, how many lunches are possible?
How many possible passwords made up of 4 letters are possible if no letter can be repeated?
Answer: 16 different lunch options
Step-by-step explanation:
Since each time, you have two new options so you have to multiply by 2.
Work backwards.
You have white or chocolate milk. You can have Strawberries or Jello with two different options so in total you have 2 * 2 = 4 different lunches. Then You have green beans or french fries each with 4 different options so 2 * (2*2) = 8 different lunches now. Then you nachos or a fish sandwich each with 8 different options so 2 * (2 * (2*2)) = 16 different lunch options.
In simpler form, you can do, 2 * 2 * 2 * 2 = 16 or [tex]2^{4}[/tex] = 16, for the four different choices you have.
64 Options.
So there is 7 options which is the nachos, fish sandwich, green beans, fries, strawberries, jello, and 2 different milks. First, add all the foods 1 + 1 + 1 + 1 + 1 + 1 + 2 = 8. Next, multiply the 8 by 8 and it will give you 64.
Thats how you get the answer.

1/6 x 6/1 = 1
3/9x2/11= 2/33
Step-by-step explanation:
Answer:
3a) 1
3b) 2/33
Step-by-step explanation:
3a. [tex]\frac{1}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex]
Reverse the 2nd fraction. That way the division sign turns into a multiplication sign.
[tex]\frac{1}{6}[/tex] • [tex]6[/tex]
1/6 and 6 cancles out and becomes 1.
[tex]1[/tex]
1 is your answer to 3a.
3b. [tex]\frac{3}{9}[/tex] ÷ [tex]\frac{11}{2}[/tex]
Reverse the 2nd fraction. That way the division sign turns into a multiplication sign.
[tex]\frac{3}{9}[/tex] • [tex]\frac{2}{11}[/tex]
Multiply.
[tex]\frac{6}{99}[/tex]
Simplify.
[tex]\frac{2}{33}[/tex]
2/33 is the answer to 3b.

A team is selling discount cards as a fundraiser. The table shows the number of cards sold and the remaining amount of money needed.
A table showing Discount Cards Fundraiser with two columns and six rows. The first column, Cards Sold, has the entries, 10, 20, 30, 40, 50. The second column, Remainder of Goal, has the entries, $875, $795, $715, $635, $555.
Which word describes the slope of the line representing the data in the table?
What would the answer be this question?
I'm being timed right now need it QUICK
Answer:
C) Negative
Step-by-step explanation:
The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the remainder of goal and x represent the cards sold.
Using points (10, 875) and (50, 555) from the table:
[tex]slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{555-875}{50-10}\\\\m=-8[/tex]
Therefore the slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
