You just have to divide 309 by 4.78 so it would =64.6443
Answer:
31 people
Step-by-step explanation:
think of it like a line,
first person at zero then add 3 feet per person so...
1 + 90/3 = 31 people
kinda funny that the problem isnt accounting for the size of the people
The ratio, r, is 20 - 13 = 27 - 20 = 34 - 27 = 7;
The nth term has the formula: an = a1 + (n-1) x r; where, a1 = 13 and r = 7;
Then, an = 13 + (n-1) x 7;
Finally, an = 13 + 7 x n - 7;
an = 7 x n + 6;
Answer: (28/37) - (48/37)*i
Step-by-step explanation:
We want to solve the quotient:
To solve it, we need to multiply the whole quotient by the complex conjugate of the denominator.
Remember that for a complex number:
a + b*i
the complex conjugate is:
a - b*i
Then if the denominatoris:
6 + i
the complex conjugate is:
6 - i
Then to solve the quotient we have:
This is equal to:
Then the initial quotient is equal to:
(28/37) - (48/37)*i
