If g(x) = 1 - ¾ x find: -5g(4) - 1

cricket20 [7]

Answer:

-5g(4) - 1 is 9

Step-by-step explanation:

$g(x) = 1 - \frac{3}{4} x$

when x is 4:

$g(4) = 1 - \frac{3}{4} \times 4 \\ = 1 - 3 \\ = - 2$

therefore:

$- 5g(4) - 1 = - 5( - 2) - 1 \\ = 10 - 1 \\ = 9$

What is the union of the set (1, 4, 6, 8 1/2,10) and (1, 3, 11/2, 6, 10 1/2)

makkiz [27]

Answer:

$(1, 4, 6, 8, \frac{1}{2}, 10, 3, \frac{11}{2})$

Step-by-step explanation:

We need to find union of given sets $(1, 4, 6, \frac{1}{2}, 10)$ and $(1, 3, \frac{11}{2}, 10, \frac{1}{2})$

We know by definition that union of two given sets say A and B is set C with all the unique and common values given in set A and B.

∴ $(1, 4, 6, \frac{1}{2}, 10)$ ∪ $(1, 3, \frac{11}{2}, 10, \frac{1}{2})$ = $(1, 4, 6, 8, \frac{1}{2}, 10, 3, \frac{11}{2})$

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
