Answer:
24 marbles
Step-by-step explanation:
P( purple) = 2/3 = purple/total
2/3 = 16/total
Using cross products
2 * total = 3 *16
2 * total = 48
total = 24
There are 24 marbles
It is 3i.
The square root of -9 is the square root of -1 times the square root of 9.
So: the square root of 9 is 3, and the square root of -1 is called i (this doesn't actually exist, it's just imaginary).
Then, the square root of -9 is 3i.
Answer:
The question = (7^3)*(7^x)
When multiplying two exponents with the same base, all you do is add the exponents together and keep the same base
Therefore,
(7^3)*(7^x) = 7^(3+x)
Step-by-step explanation:
7^3+x is the answer
Answer:
UV = 40
UY = 40
Step-by-step explanation:
The sides in YXWVU are the same as the ones in GHIJK times 10.
UV = KJ*10
UY = KG*10
