Hello!
The chance of getting a football card is 7 / 10
The chance of then getting a basketball card is 3 / 10
Multiply these two numbers
7/10 * 3 / 10 = 21/100
21/100 = 0.21
The answer is 0.21 or 21%
Hope this helps!
I assume that x = figure no.
It's better to write this as
Tiles = 10n-18
Thus 10(12) - 18
=120 - 18
= 102
THUS HE IS WRONG.
So...notice first off, the 0.6 has 1 decimal, the 0.0024 has 4 decimals
what happens is, the dot goes poof BUT, you need to add as many zeros to each number as the other's decimals.
the 0.6 has one decimal, so 0.0024 gets an added zero and loses the dot, to become 000240.
the 0.0024 has four decimals, thus the 0.6 gets added 4 zeros then, and loses the dot, to become 060000
and then you divided that, those are the dividend and divisor.
If the number is big enough there can be up to an infinite number of decimals
Answer:
x = 9/32
Step-by-step explanation:
I believe you may have meant -6 equals, so here is how I did it
-6 = 8(-8x-3)
-6 = 64x - 24
64x = 18
x = 9/32
