2/3 of 52.20 =
3 into 52.20 =17.4
17.4 x 2 = 34.8
52.20 + 17.4 =69.6
Answer:
The condensed log equation is:
Step-by-step explanation:
We use these following logarithm properties to solve this question:
In this question:
So
Becomes:
Now applying the addition and subtraction properties, we have:
The condensed log equation is:
Answer: 4y/(y+3)
Explanation:
{(2y)(4y-12)}/{(y-3)(2y+6)}
= (8y^2 - 24y)/(2y^2 + 6y - 6y - 18)
= (8y^2 - 24y)/(2y^2 - 18)
= {8y(y-3)}/{2(y+3)(y-3)}
= 2 * 4y/{2(y+3)}
= 4y/(y+3)
Answer:
42
Step-by-step explanation:
The permutation formula is P(n, r) = n! / (n - r)!. We know that n = 7 and r = 2 so we can write:
7! / (7 - 2)!
= 7! / 5!
= 7 * 6 * 5 * 4 * 3 * 2 * 1 / 5 * 4 * 3 * 2 * 1
= 7 * 6 (5 * 4 * 3 * 2 * 1 cancels out)
= 42
2.73
You need to divide 43.95 by 16.1 then round it off. That is how you get 2.73. I hope this helps and good luck!
