Answer:

Below in bold.

Step-by-step explanation:

Work in times to fill 1 pail:-

tap A takes 55/4 seconds

tap B takes 50/3 seconds

Let time to fill one pail be x when filling together, then:

3/50 + 4/55 = 1/x

165x + 200x = 55*50

x = 2750 /(365) = 7.5342 seconds

To fill 16 pails it takes 7.5342* 16

= 120.55 seconds

= 2 minutes 1 second to the nearest second..

A worker at a factory earns $12 per hour plus 2.50 for each unit produced that hour. The worker earns a total of $27 in one hour
nevsk [136]

Answer:

The total number of units produced is 6  .

Step-by-step explanation:

Given as :

The earning of worker at the factory = $ 12 per hour + $ 2.50 each unit per hour

The total earning of worker per hour = $ 27

Let The total number of unit produced = x

According to question

The wage worker earn per hour + earning  × per unit produced that hour = Total earning of worker per hour

Or, $ 12 per hour + $ 2.50 each unit per hour × x = $ 27

Or, $ 2.50 each unit per hour × x = $ 27 - $ 12

Or,  $ 2.50 each unit per hour × x = $ 15

∴   x = \frac{15}{2.50}

Or, x = 6

Hence The total number of units produced is 6  .   Answer

If f(x) = 2x + 6 and g(x) = x, what is (gºf)(0)?​
riadik2000 [5.3K]

Answer:

(gºf)(0) is 6

Step-by-step explanation:

It is a composition of functions problem, where

(gºf) = g(f(x)) is the composition of the functions g(x) and f(x). (gºf)(0) is the composition of the functions at the point x = 0. First, we find that function that is the g composite of x, then we replace x by 0.

g(4), for example, is g when x = 4, right? So g(4) = 4.

So,

g(f(x)) is going to represent g when x = f(x). x = f(x) when x = 2x + 6, so:

g(f(x)) = g(2x+6) = 2x + 6

We have that

g(f(x)) = gºf(x) = 2x + 6

Now, we just have to find the value of the function at x = 0. So

gºf(0) = 2(0) + 6 = 0 + 6 = 6.

(gºf)(0) is 6
