how do you work out what 8 cubed is ?
Step-by-step explanation:
so do you have building blocks cuz you use it and then after you do that you get the cue that has an eight on it and then you would keep on adding on and then that would be the answer
Answer:
512.
Step-by-step explanation:
8 cubed is the same as 8 to the third power.
We usually use other ways to represent certain number to the power to help make equations easier and write less so,
instead of saying: 2 to the second power; we say 2 squared.
Instead of saying 2 to the third power; we say 2 cubed.
The number 2 was used just as example, it could be any number.
so 8 cubed = 8 to the third power so,
8 cubed = [tex]8^{3}[/tex] = 8x8x8 = 512

I=0.13x+1025 A textbook salesperson's monthly income depends on the amount of his sales. His monthly income is a salary of $1025 $ 1025 plus 13% 13 % of his monthly sales. Write a linear equation for his monthly income for sales of x dollars. ( I=mx+b I = m x + b ).
Answer:
l = 0.13x+1025
Step-by-step explanation:
Let the monthly sales be x
Monthly income = $1025 + 13% of monthly sales
Monthly income = $1025 + 0.13x
Since l represent the monthly income
l = 1025+0.13x
Rearrange
l = 0.13x + 1025
Hence the linear equation representing the statement is l = 0.13x+1025

Step-by-step explanation:
60×0.75=45
Hope this helps
At the big fish store, Sarah has a coupon good for 25% off any purchase. She will pay $45 for a $60 item if she purchases it at a reduced price.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that Sarah has a coupon for 25% off any item at the big fish store. If she buys an item regularly marked $60,
Sale price =Original price - discount
Sale price = $60 - 25% of $60
Sale price = $60 - $ 15
Sale price = $45
Thus, at the big fish store, Sarah has a coupon good for 25% off any purchase. She will pay $45 for a $60 item if she purchases it at a reduced price.

Fernando has a prime number of books between 21 and 30 he says that if he takes 4of the books away he will be able to place the same number of books on wacho shelf of this bookcase how Many books does fernando have how many shelves are on the bookcase
Answer:
29 books ; 5 bookshelfs
Step-by-step explanation:
Solving logically ;
Prime numbers between 21 and 30 = 23, 29
Hence, number of books Fernando has is either 23 or 29
Taking 4 away from the number of books, he'll be able to arrange same number of books on each of his book shelve;
From the statement, we can conclude that :
Subtracting 4 from the number of books Fernando has should give a perfect square
If 23 books
23 - 4 = 19 ; 19 isn't a perfect square
If 29 books :
29 - 4 = 25
Hence, to place the same Number of books on each shelf :
Sqrt(25) = 5
Hence, number of bookshelf = 5

Mathilde has 20 pints of green paint. She uses 2/5 of it to paint a landscape and 3 /10 of it while painting a clover. She decides that, for her next painting, she will need 14 pints of green paint. How much more paint will she need to buy?
Answer:
8
Step-by-step explanation:
Total pints of paint = 20
For landscape :
2/5 * 20 = 8 pints
For clover :
3/10 * 20 = 6 pints
Total used = (8 + 6) = 14
Pints left = 20 - 14 = 6 pints
14 required for next painting
14 - 6 = 8 pints
8 more pints needed

Write an expression to show 5 fourths times the product of 3 and 1 fourth.
Answer:(5/4)(3/4)
Step-by-step explanation:
Hello,
First of all, an expression does not have an equal sign, unlike an equation.
First, start with the fraction 5/4.
Second, know that the whole number, 3, and the fraction, 1/4, are being multiplied.
(3)(1/4)=(3*1)/4=3/4
Finally, 5/4 * the product of 3 and 1/4 is:
(5/4)(3/4)

Answer: No Solution
Step-by-step explanation:
Given
2(6x+5)=-3(-4x+3)
Expand parenthesis
2·6x+2·5=(-3)·(-4x)+(-3)·3
12x+10=12x-9
Subtract 12x on both sides
12x+10-12x=12x-9-12x
10=-9
10 will never equal -9, which means this is No Solution

2 (6X + 5) = -3 (-4X+3)
