why isn't m^3=512 ±8, but just 8? I went onto 2 diff websites and the answer book (yes i have an answer book) and it says 8.
Because of that, when do you add ± in questions like the ones on top? (take into account units and no units, thanks)
i'm confusion
Also, why do you need (x) in questions like (-7)^3? I feel like there is no point, especially when it is just one problem.
Answers
Answer: It is only +8 because it is an odd power, so you're only multiplying 3 numbers together and not 2 or 4 and so on. Any odd power is always only going to have 1 answer because if you try the other one then it comes out to be the opposite.
You only need the parenthesis if you want to plug it into a calculator because -7 in a calculator is taken as subtracting 7 while (-7) is taken as a negative 7. They are just building good habits early.

(5,15)
Step-by-step explanation:
We know that 225 = 15a + 10c, and he purchased a total of 20 tickets, so
a + c = 20, using this, we know that c = 20 - a, we can substitute this for c in 225 = 15a + 10c to get:
225 = 15a + 10(20 - a) =
225 = 15a + 200 - 10a
225 = 5a + 200
25 = 5a
a = 5
Now we substitute 5 for a:
225 = 15a + 10c
225 = 15(5) + 10c
225 = 75 + 10c
150 = 10c
c = 15
so a = 5 and c = 15, the solution is (5,15)

Answer:
77.5
Step-by-step explanation:
Given:
Scores: 65, 70, 75, 80, 85, 90, 95
Number of Students: 8, 5, 3, 6, 6, 4, 2
Step 1: Calculate the sum
Sum = (65 * 8) + (70 * 5) + (75 * 3) + (80 * 6) + (85 * 6) + (90 * 4) + (95 * 2)
= 520 + 350 + 225 + 480 + 510 + 360 + 190
= 2635
Step 2: Calculate the mean
Mean = Sum / Total Number of Students
= 2635 / (8 + 5 + 3 + 6 + 6 + 4 + 2)
= 2635 / 34
≈ 77.5

Is -4/5 rational or irrational
Answers
Answer: Rational
Step-by-step explanation:
The number -0.8 is rational if it is an integer or decimal
A rational number is a number that can be represented as a/b where a and b are integers and b is not equal to 0.
Since -0.8 is an integer or decimal from above, -0.8 is also a rational
An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number.
Answer:
It is a rational number
Step-by-step explanation:
An irrational is a number that repeats in a sequence or not.
It is a number that never stops. ex. pi, 2/3.
-4 divided by 5 is -0.8 which is a rational number

Find the number that makes the ratio equivalent to 20:9.
__:27
Answers
Answer:
60
Step-by-step explanation:
You can kinda think it out by looking at the 9 and 27. Change 9 to 27 by multiplying by 3. So then, multiply 20×3 also.
20:9 is the same as
60:27
Or you can do some auto-pilot algebra, like this:
20/9 = x/27
crossmultiply.
9x = 540
divide by 9
x = 60

A = 9.2 cm sq
A of 2 triangles = 9.2*2 = 18.4 cm sq
Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq
A of 3 rectangles = 75*3 = 225 cm sq

6.66666666667 as a fraction
Answers
Answer:
33/50
Step-by-step explanation:
The fraction equivalent to 6.66666666667 is 66666666667/10¹¹.
Step 1: Let x be equal to 6.66666666667.
x = 6.66666666667
Step 2: Multiply both sides of the equation by a power of 10 to eliminate the decimal places.
Since there are 11 decimal places in the number, we can multiply both sides by 10¹¹
10¹¹x = 10¹¹ (6.66666666667)
10¹¹x = 66666666667
Step 3: Simplify the equation and write it as a fraction.
x = 66666666667 / 10^11
Step 4: Further simplify the fraction if possible.
In this case, we can see that the numerator is already the desired integer, but the denominator can be expressed as 10 raised to the power of 11.
x = 66666666667 / (10^11)
Therefore, the fraction equivalent to 6.66666666667 is 66666666667/10¹¹.

A point on a pre-image is currently located at (1, -3). The pre-image is translated 3 units right and 6 units up.
What are the NEW coordinates for the point after the translation? Use graph paper to sketch the translation if needed.
A. (3, 4)
B. (4, 3)
C. (7, 0)
D. (-2, 2)
Answers
Answer:
(4, 3)
Step-by-step explanation:
To solve:
First we have to move 3 units right. This means that we have to increase the x axis, because we move left and right on the x axis. This gets you to the coordinates (4, -3).
Now, to move six units up, add 6 to -3. Instead of counting, using the mathematical way makes it easier to calculate. This gets us a y axis point of 3, since the y axis runs from up to down. When we read the final point out loud, this gives us the answer of ...
(4, 3); 4 on the x axis and 3 on the y axis.

On this note;
Sum of 1 and 2 is;
180 = 124 + (2x + 4)°
(2x + 4)° = 180 -124
2x = 56 -4

Answer: 21
Explanation:
We start by trying to figure out what age you were to start.
We represent your current age with x. So the question now reads:
x-6=(x+4)1/2
We simplify each side with distributive property.
x-6=1/2x +2
subtract 1/2x from each side to isolate the variable. And add 6 to each side
1/2x=8
Multiply each side by 2
x=16
Therefore you are currently sixteen and "five years from now" you will be 21.
