Decimal: It’s easier to work with the numbers You can add, subtract, multiply and divide in your head (for the most part) instead of having to find common denominators and things like that.
Fraction: You can put repeating values in fraction form to represent them in a simpler way, as opposed to having to put the line over the repeating digits if it were in decimal form.
Power: Powers are just condensed forms of repeated multiplication, so they save space/time and you can use certain properties with some powers that allow you to multiply and divide them instantly.
Scientific notation: This is good when you’re dealing with numbers that have a lot of digits/place value. That can become confusing, so scientific notation is a way we can represent these numbers clearly and more condensed (takes less space/time).
11 + 5 = 16
6 are open out of the 16. 6 : 16 is the ratio. But we can reduce it.
Divide each side by 2
6/2 = 3
16/2 = 8
3 : 8 is the ratio when simplified.
Answer:
150cm^2
Step-by-step explanation:
Volume of the cube=125cm^3
Side^3=125cm^3
Side =5cm
So the total surface area =6×side^2
=6×5×5
= 150cm^2
So the total surface area is150cm^2
The inverse function of is b(a) = a/6 - 9
<h3>How to determine the inverse function?</h3>
The function is given as:
Divide 12 by 2
Rewrite the function as
Divide both sides by 6
a/6 = b + 9
Subtract 9 from both sides
b = a/6 - 9
Express as a function
b(a) = a/6 - 9
Hence, the inverse function of is b(a) = a/6 - 9
