Answer:
========================================================
Explanation:
The reciprocal of x is 1/x where x is nonzero. Multiplying x with 1/x leads to 1. For example, the numbers 9 and 1/9 are multiplicative inverses of each other.
We'll stick 1 over the given square root expression. Then follow these steps to rationalize the denominator.
In short,
Answer:
3/91 ; 36/91
Step-by-step explanation:
1) favourable event/ total possibilities * favourable event/ new total possibilities
3/14 * 2/13 = 3/91
2) it is simplier calculate the probability of the opposite event (no balls are blue)
11/14 * 10/13 = 55/91
91 - 55 = 36
final answer 36/91
Answer:
D.
Step-by-step explanation:
1600 * .5 = 800
800 + 200 = 1000
Answer:
x = 3
b³
Step-by-step explanation:
when you multiply numbers with the same base, you add the exponents. you can do this for both the top and bottom equations on the fraction.
b¹ × b⁷ = b⁸
b³ = b² = b
when you divide numbers with the same base, you subtract them.
b⁸ ÷ b⁵ = b³
