Answer:
1. Irrational 2. Rational
Step-by-step explanation:
[tex]\sqrt[3]{81}[/tex] = [tex]\sqrt[3]{3^4}[/tex]
= [tex]\sqrt[3]{3^3\cdot 3}[/tex] = [tex]\sqrt[3]{3^3}[/tex] [tex]\sqrt[3]{3}[/tex]
= 3 [tex]\sqrt[3]{3}[/tex] OR in decimal form which is 4.32674...
4.32674... is an irrational number because it cannot be expressed as a ratio of two integers such as in m/n form.
Examples of irrational : [tex]\pi[/tex], 4.32674... and so on
[tex]\sqrt[3]{-64}[/tex] = - [tex]\sqrt[3]{64}[/tex]
= - [tex]\sqrt[3]{4^3}[/tex] = -4
-4 is a rational number because it can be written as a fraction same thing that I said in number 1.
Examples of rational : -4 = -4/1 , 8/9 and so on
Hope this helps!

Answer:
At the top left, you've done the table correctly.
On the bottom left (just below it) I believe the "one-time fee" is $9, as that is your y-intercept (where the x value is 0, the y-value is 9). The teacher worded this very poorly. Your equation is y = x + 9
Now to the top right of the paper, you've drawn the line correctly. Now I'd like to take this moment to explain that you should've been able to use this line to create the equation.
To the bottom left now, for number 3, you will run out of money in 3 days.
For number 4, you can either:
A: Be the class clown and put "yes"
or (the more correct version)
B: Circle where the line crosses the y-axis, at (0,9) and circle the area that you drew showing that the slope is 1.

Answers
Answer:
A
Step-by-step explanation:
If you were to graph each option, only A would pass the vertical line test since no coordinate has the same x value
The choice y a function of x is A. (1, 3), (3, 4), (4, 5), (5, 6).
If you were to graph each option, only A would pass the vertical line test since no coordinate has the same x-value.
We have given that,
A. (1, 3), (3, 4), (4, 5), (5, 6)
B. (2,0), (2, 3), (4, 5), (6, 7)
C. (2,5), (4,8), (6, 10), (2, 12)
D. (6,2), (4, 1), (6, 8), (8, 10)
The choice is y a function of x.
If you were to graph each option, only A would pass the vertical line test since no coordinate has the same x-value.
What is the vertical line test?The vertical line test is a method that is used to determine whether a given relation is a function or not. The approach is rather simple.
Therefore option A is correct.
The choice y a function of x is A. (1, 3), (3, 4), (4, 5), (5, 6).

Going into the final exam, which will count as 1/3 of the final grade, Megan had test scores of 94, 81, 87, and 93. What score does Megan need on the final exam in order to have an average of 90?
Answers
Answer:
Megan needs a 95 to get an average of 90.
Step-by-step explanation:
Add up the test scores Megan has earlier, you would get 355 as a result of all scores added. In order to get an average of 90%, you would need to accumulate 450 points which she will need to take her final exam on it. Subtract 355 from 450 to get a score of 95% in which she will need that score to average it to 90%.

Answer:
Step-by-step explanation:
2X+4)+(2X+4)+X+X=38
Lets add our X's and then add our whole numbers. 6X+8=38
Lets work our sentence by subtracting 8 from each side of the equal sign.
6X+8–8=38–8
6X=30
Lets divide each side by 6.
6X/6=30/6
X=5 now lets prove 5 is X.
(2×5+4)+(2×5+4)+5+5=38
(14)+(14)+5+5=38
28+10=38
38=38
X is equal to 5.

2700 cubic feet
Step-by-step explanation:
To find the volume of the figure, we need to find the separate volumes of the cuboids. The formula for the volume of a cuboid is length × breadth × height.
Volume of bigger cuboid = 11 × 10 × 22
= 2420
Volume of smaller cuboid = 10 × 4 × 7
= 280
Volume of figure = 2420 + 280
= 2700 cubic feet

how would i format the sequence? (or if it's easier, what is the r value?) i keep struggling with forming the proper one
Answers
Step-by-step explanation:
In an AP, 2a2 = a1 + a3.
=> 2(x + 11) = (2x + 1) + (4x + 5)
=> 2x + 22 = 6x + 6
=> 4x = 16

An item is regularly priced at $71. It is now priced at a discount of 35% off the regular price.
Answers
Answer:
$46.15
Step-by-step explanation:
So you can just multiply the 71 by 0.65 becuase your paying 65 percent of the price now since it’s 35 percent off and you’ll get 46.15
OR
You can just multiply 0.35 by 71 and get 24.85. Then subtract that form 71. You’ll get 46.15
Answer:
Discount amount: $24.85
New price with the discount included: $46.15
Step-by-step explanation:
I don't know what you are trying to solve, but here's the work for various things. You can pick the answers you need if you see them here.
1. Find the amount of the discount.
Multiply the retail price by the discount percentage.
$71 x 35% = $24.85
$24.85 is the total discount that was taken off of the original price.
2. Find the price of the item after the discount.
Subtract the amount of the discount from the original price.
$71.00 - $24.85 =$46.15
$46.15 is the new price.
