0.6¯¯¯ is... irrational because it is a repeating decimal irrational because it can't be written as a fraction rational because it is a decimal that goes on forever without repeating rational because it can be written as a fraction
Answer:
The number is irrational because it can’t be written as a fraction
Step-by-step explanation:
Here, we want to state why the given number is irrational
Mathematically, an irrational number is one that cannot be expressed as the ratio of two integers
Thus, the reason why the number is irrational is because it can’t be written as a fraction

Solve the following system of equations and show all work.
Please show all work
Answer:
-1/2 and -1
Step-by-step explanation:
Our system of equations is:
y = 2x²
y = -3x - 1
We can set the y's equal to each other:
y = 2x² = -3x - 1
Now, we have:
2x² = -3x - 1
Move all the terms to one side by adding both sides by 3x and 1:
2x² + 3x + 1 = 0
We must factor this quadratic. Note that the factoring is:
(2x + 1)(x + 1) = 0
Our solutions are now:
2x + 1 = 0 OR x + 1 = 0
x = -1/2 x = -1
.
Thus, our solutions are -1/2 and -1.

1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent
3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.
Answer:
Step-by-step explanation:
1). Slope of a line shown on the graph will be,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{1}[/tex]
= -4
2). Slope of the given horizontal line can be determined by,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Since, rise of the given line is zero.
Therefore, slope of the given horizontal line will be 0.
3). Slope of the line passing through the indicated line = -2
Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).
Answer:
Step-by-step explanation:
1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.
2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.
3. A graph through the indicated point with a slope of -2.
8/12- 3/8 show your work with a quation

Here's how to subtract 3/8 from 8/12:
8

−

Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 8 by 8, and get 64.
Then we multiply 3 by 12, and get 36.
Next we give both terms new denominators -- 12 × 8 = 96.
So now our fractions look like this:
64
96
−
36
96
Step 2
Since our denominators match, we can subtract the numerators.
64 − 36 = 28
So the answer is:
28
96
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
28
96
÷ 2 =
14
48
Let's try dividing by 2 again...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
14
48
÷ 2 =
7
24
Let's try dividing by 2 again...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 7. So we're done reducing.
There you have it! The final answer is: 0.29166666666

What is the difference between 10 x 4 + 5 and 10 x (4 + 5).
Answer:
The difference is that in the first equations you multiply the 10 by 4 first because of PEMDAS rule. But in the second equation you add the 4 and 5 before multiplying. Thats the only difference :D
Step-by-step explanation:
I hope this helps!!!!
Answer:
[tex]10*4+5\\By\ applying\ BODMAS, as\ there\ are\ no\ brackets\ we\ directly\ multiply(M)\ 10\\ with\ 4\ and\ add(A)\ the\ product\ with\ 5.\\[/tex]
[tex]Hence,\\10*4+5\\=40+5\\=45[/tex]
[tex]10*(4+5)\\By\ applying\ BODMAS,\ due\ to\ the\ presence\ of\ the\ brackets\ we\ carry\\the\ operations\ inside\ the\ bracket.\\ Hence,\\10*(4+5)\\=10*9\\=90[/tex]

An album sells for $16.00 through an online music service. If the album is 10% off, and sales tax is 8%, what is the total price of the album including tax? A. $15.70 B. $15.68 C. $16.42 D. $15.55
Answer: B. $15.68
Step-by-step explanation:
Given: Selling price of album = $16.00
Discount = 10% off
Sales tax = 8%
Discount = 10% of ( Selling price of album)
= 10% of $16
= 0.1 ($16)
= $1.6
Sales tax = 8% of ( Selling price of album)
= 8% of $16
= 0.08 ($16)
= $ 1.28
Total price of the album including tax = Selling price of album +Sales tax - Discount
= $ 16 + $1.28 - $1.6
= $ 15.68
Hence, B. is the correct option.

A space probe is launched from a platform that is just above 100 meters below sea level. The probe is expected to travel into deep space indefinitely. Write an equality showing the altitude of the probe after it is launched.
Answer:
x ≤ ∞
Step-by-step explanation:
Let x represent the height of the space probe above sea level in meters.
Initially, before launch, the space probe is launched from a platform that is just above 100 meters below sea level, hence:
x < -100 (the negative sign shows that it is below sea level).
After launch, The probe is expected to travel into deep space indefinitely. Therefore the height of the probe after it is launched is represented by the inequality:
x ≤ ∞

The sum of two consecutive numbers is 723. FInd the numbers.
Answer:
361 and 362
Step-by-step explanation:
a+b=723
b-a=1
b=1+a
a+1+a=723
2a+1=723
2a=723+1
2a=724
a=362
362+b=723
b=723-362
b=361
so b and a are 361 and 362 respectively
hence the consecutive numbers are 361 and 362

John earns $7.50 an hour. How many hours will John have to work to earn $600?
Divide John's goal amount by his hourly rate to find the answer.
$600 ÷ $7.50/hour = 80 hours.
So, John will have to work a total of 80 hours in order to earn $600.
Answer:
80
Step-by-step explanation:
If you divide 600 with 7.50 you will get 80.
That is simple!
Find the GCD (or HCF) of numerator and denominator
GCD of 600 and 750 is 150
Divide both the numerator and denominator by the GCD
600 ÷ 150
750 ÷ 150
Reduced fraction:
4
5
Therefore, 600/750 simplified to lowest terms is 4/5.
Ratios. Fill in the blank using the Word Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla. How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?
Answer:
3 batches of cookies
Step-by-step explanation:
Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.
How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?
We can calculate the batches using either cups of flour or number of teaspoons.
For flour
5 cups of flour = 1 batch of cookies
15 cups of flour = x
Cross Multiply
5x = 15 × 1
x = 15/5
x = 3 batches of cookies
For teaspoons of vanilla
2 teaspoons of vanilla = 1 batch of cookies
6 teaspoons of vanilla = x
Cross Multiply
2x = 6 × 1
x = 6/2
x = 3 batches of cookies.
Hence: you can make 3 batches of cookies with 15 cups of flour and 6 teaspoons of vanilla
