What are , rational numbers and irrational numbers?

Rational numbers are numbers which can be written in the form of where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.

Irrational numbers are those real numbers which are not rational numbers.

Therefore,

0.02 and 2 are rational numbers because they can be represented as fractions,

2/100 and 2/1

Also √2 and √12 are irrational numbers, since they cannot be represented as fractions

A saleswoman earns 40% commission on all the merchandise that she sells. Last month she sold \$900 worth of merchandise. How much commission (in dollars) did she earn last month?

Step-by-step explanation:

\$360

Step-by-step explanation:

Given last month, she sold \$900

given,

commission = 40% of merchandise sold

= (40/100) of merchandise sold

= (40/100) x \$900

= \$360

Step-by-step explanation:

If x varies inversely with y and x = 8 when y = 6, find y when x = 10. a.
Y equals begin fraction five over twelve end fraction

b.
y = 4.8

c.
y = 7.5

d.
Y equals begin fraction forty over three end fraction

y = 4.8

Step-by-step explanation:

Given that x and y vary inversely then the equation relating them is

y = ← k is the constant of variation

To find k use the condition x = 8 when y = 6, thus

k = yx = 6 × 8 = 48

y = ← equation of variation

When x = 10, then

y = = 4.8

What is the % of 7/10

Step-by-step explanation:

PLEASE HELP Suppose y varies directly with x, and y=10 when x= -3. What direct variation equation relates x and y ? What is the value of y when x= -1?

y =

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 10 when x = - 3, thus

k = = = -

y = - x ← equation of variation

When x = - 1, then

y = - × - 1 =

If cos x = 0.9341, find the measure of angle x to the nearest degree.

x = 21° or 339°

Step-by-step explanation:

We are given that cos x = 0.9341.

So, cosine of x is positive and then x can be in first quadrant or fourth quadrant.

Now, ≈ 21° (to the nearest degree)

So, x = 21° or (360 - 21)° = 339° (Answer)

If R is the set of all integers, choose the set S that will make the following statement false. S ⊆ R
1S = {−2, −1, 0, 1, 2}
2S = {0, 0.5, 1, 1.5}
3S = {0}
4S = {1, 2, 3, 4}

Answer: 1 S = {−2, −1, 0, 1, 2}

Step-by-step explanation:

Integers are whole numbers that could be positive or negative .

This means that

R = { ... -3 ,-2 , -1 , 0 , 1 , 2 , 3 , 4 , ...}

S ⊆ R means that all elements of S is also an element in R , therefore :

S = { -2, -1 ,0, 1 , 2 ...}

slope = -

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (5, - 1)

m = = = -

Step-by-step explanation:

Determine whether the number could be the probability of an event. Explain your reasoning. 2.3 I AM OFFERING 90 POINTS TO WHOEVER ANSWERS THIS CORRECT

No, it can't be the probability of an event.

Step-by-step explanation:

Probabilities range from 0 to 1, and 2.3 goes above 1 so it can't be a probability.

That's all I can do to explain, sorry I'm late and that my explanation is short!

(a) 33.3% (b) -1.5 (c) 0.0002 (d) 0 (e) 320/1058 (f) 64/25

a. possible

b. not possible

c. possible

d. possible

e. possible

f. not possible

Explanation:

The probability of an event must be between 0 and 1 (including 0 and 1 both). Since 33% is equal to 0.33, it is between 0 and 1, thus it is a possible probable event. -1.5 is not between 0 and 1. The next option is between 0 and 1.

0 can also be a possible probable event. The next option is also between 0 and 1 which can be probability of an event. But the last option is not between the range of 0 and 1, thus can not represent probability of an event.
