Answer:
405.
Step-by-step explanation:
This is a geometric sequence where the nth term = a1 r^(n -1).
Here a1 = 5 and r = 3 so
the fifth term a5 = 5(3)^(5-1)
= 5 * 81
= 405.
Answer:
Mary = 24
Chau = 15
David = 48
Step-by-step explanation:
The formula is
Mary + Chau + David = 87
And we know that
Chau = Mary - 9
David = Mary * 2
So when we fill this in
Mary + Mary - 9 + Mary * 2 = 87
4Mary - 9 = 87
4Mary = 96
Mary = 24
Chau = Mary - 9 = 15
David = Mary * 2 = 48
The square root of 35 is 5.9
hope this helps
Multiply 6 by 9 (whole number by denominator)
then add that to 15 (the product to the numerator.
