What type of problems can you solve using operations with rational numbers?

Answers

Answer 1

Answer:

like real numbers, the arithmetic operations, such as addition, subtraction, multiplication and division are applicable to the rational numbers

Answer 2

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".

Answers

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

Answers

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

How many possible passwords made up of 4 letters are possible if no letter can be repeated?

Answers

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.

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

Answers

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.
