The world brand of rivet placement is 11209 rivets in 9 hours and belongs to J. Mair of Ireland. If another person places 11209
Ilya [14]

Answer:

4.74 hours

Step-by-step explanation:

Given that both person have to place same number of rivets that is

11209

first person take 9 hours to complete the work

hence 1 hour work of 1st person is \frac{1}{9} of total work

second person takes 10 hours to complete the same work

hence 1 hour work of 2nd person is \frac{1}{10}

Now if both work together then

1 hour work of both person = \frac{1}{9} +\frac{1}{10} =\frac{19}{90}

thus working together they need \frac{90}{19} hours = 4.74 hours to complete the whole work which is placing 11209 rivets

-5(w+4) +8< - 42 need a quick answer
Nesterboy [21]

Answer:

w > 6

Step-by-step explanation:

Let's solve your inequality step-by-step.

−5(w+4)+8<−42

Step 1: Simplify both sides of the inequality.

−5w−12<−42

Step 2: Add 12 to both sides.

−5w−12+12<−42+12

−5w<−30

Step 3: Divide both sides by -5.

\frac{-5w}{-5} < \frac{-30}{-5}

w > 6

<u>Answer: </u>

<u />w > 6

Thanks!

These are the fees for sending a package by Media Mail:
Serga [27]
For first pound it is = $2.41
For next six, = 0.41 * 6 = $2.46

Remaining = 7.99 - (2.41 + 2.46) = 7.99 - 4.87 = 3.12

Now, additional pounds = 3.12 / 0.39 = 8
Total weight = 1 + 6 + 8 = 15

In short, Your Answer would be 15 pounds

Hope this helps!
