In a company, 80% of the workers are women. if 880 men work for the company, how many workers are there in all?
ELEN [110]
If 80% are women, then 20% are men

20% of what equals 880
0.20x = 880
x = 880/.20
x = 4400

check..
men : 20% of 4400 = 0.20(400) = 880
women : 80% of 4400 = 0.80(4400) = 3520
totaling : 3520 + 880 = 4400

so there are a total of 4400 workers

4(3x+2)-2 <br> find x show how you did it
olganol [36]

Answer:

Multiply 4 to the terms inside the parentheses.

(12x+8)-2

Remove the parentheses and equate it to zero.

12x+8-2 = 0

Simplify

12x+6 = 0

Transpose 6 to the other side.

12x = -6

Divide bith sides by 12.

12x/12 = -6/12

Simplify.

x = -6/12 or -½

What is the 6th term of the geometric sequence where a1 = 1,024 and a4 = −16? 1 −0.25 −1 0.25
VLD [36.1K]

The n-th term is given by

a_n=a_1\cdot r^{(n-1)}\qquad\text{where r is the common ratio}

Then we can find the common ratio from the given terms.

\dfrac{a_4}{a_1}=\dfrac{a_1\cdot r^{(4-1)}}{a_1}=r^3=\dfrac{-16}{1024}=\left(\dfrac{-1}{4}\right)^3\\\\r=\dfrac{-1}{4}\\\\a_6=1024\left(\dfrac{-1}{4}\right)^5=-1

The appropriate choice is -1.
