1. It must be divisible by 2 and 3. It IS divisible by 2. it IS divisible by 3. No remainder.
2. Add the digits and see if the sum is divisible by 3. Apply this rule to both numbers. 3 is not a common factor.

I really need help please

Answer:

So we have two given angles- 31* and 43*.

First we add those together.

31* + 43* = 74*

Then, we subtract that amount from 180*

180* - 74* = 106*

106* is the missing angle.

x106* - 31* = 75*

x106* + 43* = 149*

~Hope this helps~

Let g(x)=9x−10 and evaluate g(x+h)−g(x)/h

castortr0y [4]

Answer:

$\frac{g(x+h)-g(x)}{h}=9$

Step-by-step explanation:

we have

$g(x)=9x-10$

To find out g(x+h) substitute the variable x by the variable (x+h) in the function g(x)

$g(x+h)=9(x+h)-10$

$g(x+h)=9x+9h-10$

Evaluate

$\frac{g(x+h)-g(x)}{h}$

we have

$g(x+h)=9x+9h-10$

$g(x)=9x-10$

substitute in the expression

$\frac{9x+9h-10-(9x-10)}{h}$

$\frac{9x+9h-10-9x+10)}{h}$

$\frac{9h}{h}$

$9$

therefore

$\frac{g(x+h)-g(x)}{h}=9$

The navy contract was for 2,314 devices and took 23 workers two weeks (40 hours per week) to complete. The army contract was for

AlekseyPX

Answer:

0.408 hour / device

Step-by-step explanation:

As we know The army contract was for 4,707 devices that were produced by 16 workers which means 1 worker can produce: $\frac{4707}{16}$ ≈294 devices in 3 weeks.

<=> 294 devices= 3*40 hours

<=> 294 devices = 120 hours

<=> 1 device = 120/294 = 20/49 ≈ 0.408 hour

So it takes 0.408 hour for a worker to finish producing 1 devicein the army contract
