Answer:
Rational TerminatingStep-by-step explanation:
A Rational number is one that can be expressed as a fraction where the denominator is not zero. The above decimal can be expressed as a fraction in the form : ¹⁸⁶/₁₀₀₀
The decimal is also a terminating decimal which describes a decimal number that has a certain number of digits after the decimal point. In other words, the digits after the decimal point do not go on forever. 0.186 has three digits after the decimal meaning it does not go on forever.

Answer: 200km
Step-by-step explanation:
200 mm and 200cm are too small.
Answer:
I believe the answer would be 200 km.

Prince Charming invests $3000 for 5 years at a rate of 4% per year simple interest.
Calculate the total interest he will receive.
Answer:
$ 600
Step-by-step explanation:
From the question given above, the following data were obtained:
Principal (P) = $ 3000
Time (T) = 5 years
Rate (R) = 4%
Interest (I) =?
The total interest he will receive can be obtained as follow:
I = PTR/100
I = 3000 × 5 × 4 / 100
I = 60000 / 100
I = $ 600
Thus, the total interest he will receive is $ 600
The amount of $600 received by Prince Charming on the investment of $3000 for 5 years.
Prince Charming invests $3000, thus the principal amount is $3000.
He invest the same amount for 5 years, thus time we have to paid on this principal is 5 years.
The rate for which the principal amount increase is 4 %.
The formulated way to represent the simple interest (I) after passing t years of time, at a rate of r % and having a principal amount of P is mentioned below.
[tex]I=\dfrac{P \times r \times t}{100}[/tex]
Substitute the given values in the above formula to calculate simple interest.
[tex]\begin{aligned}I&=\dfrac{3000 \times 4 \times 5}{100}\\&=600 \end{aligned}[/tex]
Thus, the amount of $600 received by Prince Charming on the investment of $3000 for 5 years.

Deshawn has two bags of marbles. The first bag has 2 blue, 3 orange, and 5 red. The second bag has 4 pink, 10 blue, and 6 brown. If he pulls a marble out of each bag, what is the probability that he will pull out a blue marble from each bag
Answer: 0.1
Step-by-step explanation:
Given
Bag-I has 2 blue,3 orange, 5 red
Bag-II has 4 Pink,10 blue, 6 brown
No of ways of choosing a blue marble from bag-I
[tex]\Rightarrow ^2C_1[/tex]
Total no of ways of choosing a marble from bag-I
[tex]\Rightarrow ^{10}C_1[/tex]
No of ways of choosing a blue marble from bag-II
[tex]\Rightarrow ^{10}C_1[/tex]
Total no of ways of choosing a marble from bag-II
[tex]\Rightarrow ^{20}C_1[/tex]
The probability that he will pull out a blue marble from each bag is
[tex]\Rightarrow P=\text{Probability of pulling a blue marble from bag-I}\times \text{Probability of pulling a blue out bag-II}[/tex]
[tex]\Rightarrow P=\dfrac{^2C_1}{^{10}C_1}\times \dfrac{^{10}C_1}{^{20}C_1}\\\\\Rightarrow P=\dfrac{2}{10}\times \dfrac{10}{20}=\dfrac{1}{10}[/tex]

f(x)=2x^2-8x from x=2 to x=5. Simplify your answer as much.
We need to find [f(b) - f(a)]/(b - a).
Let a = 2
Let b = 5
f(2) = 2(2)^2 - 8(2)
f(2) = 8 - 16
f(2) = -8
We now find f(5).
f(5) = 2(5)^2 - 8(5)
f(5) = 50 - 40
f(5) = 40
[f(5) - f(2)]/(5 - 2)
(40 - (-8))/(3)
(40 + 8)/3
48/3 = 16
The average rate of change is 16.

Solve systems of equations for y and x:
−9x + 4y = 6
9x + 5y = −33
Answer:
[tex]y = -3[/tex]
[tex]x = -2[/tex]
Step-by-step explanation:
Given
[tex]-9x + 4y = 6[/tex]
[tex]9x + 5y = -33[/tex]
Required
Find x and y
To eliminate x, we simply add both equations
[tex]-9x = 9x + 4y + 5y= 6 - 33[/tex]
[tex]9y= -27[/tex]
Divide by 9
[tex]y = -27/9[/tex]
[tex]y = -3[/tex]
Substitute -3 for y in [tex]9x + 5y = -33[/tex]
[tex]9x + 5 * -3 =-33[/tex]
[tex]9x - 15 =-33[/tex]
Add 15 to both sides
[tex]9x =-15 -33[/tex]
[tex]9x =-18[/tex]
Divide by 9
[tex]x = -18/9[/tex]
[tex]x = -2[/tex]

A number is greater than or equal to -3and less than or equal to 0
Answer:
[tex]1)\ 9 : 4 = 2.25 : 1[/tex]
[tex]2)\ -3 \le x \le 0[/tex]
Step-by-step explanation:
Solving (1):
[tex]9 : 4[/tex]
Express as a unit ratio
This implies that, the second term must be 1. So, divide by 4
[tex]9 : 4 = 9/4 : 4/4[/tex]
[tex]9 : 4 = 2.25 : 1[/tex]
Solving (2):
Let the number be x.
x [tex]is\ greater\ than\\[/tex] or equal to -3 means:
[tex]x \ge -3[/tex]
x [tex]is\ less\ than[/tex] or equal to 0 means:
[tex]x \le 0[/tex]
So, we have:
[tex]x \ge -3[/tex] and [tex]x \le 0[/tex]
Rewrite as:

Write together:
