Hello there, and thank you for posting your question here on brainly.

So, we have the equation 4 * [6 + (27 / 3) + 11]

We do the ( ) parenthesis first.

27 / 3 ==> 9

Now, we have 4 * [6 + 9 + 11]

Do the [ ] now, but from left to right.

6 + 9 ==> 15

Now, we have 4 * [15 + 11]

Do the [ ]  again.

15 + 11 ==> 26

Finally, we multiply that by 4.

4 * 26 ==> 104 

104 is your final answer.

Hope this helps! ☺♥

PLZZZZZZZZZZZZZZZZ HELP ME!!!<br><br> 1 1/8 to decimal show your work!!!
lions [1.4K]

Answer:

1.125

Step-by-step explanation:

1) First you have to turn it into an improper fraction

8*1 = 8. Add the numerator--> 8+1 = 9.

2) The improper fraction is 9/8

3) Divide 9 by 8

 **Write this using long division

8 goes into 9 one time, so we will write one as our first digit

Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.

And this point we have 1.1 above

Carry down the 2 and the 0, 8 goes into 20 2 times so write 2

At this point we have 1.12

Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.

Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.

The manager of a store orders model railroad sets that cost $390 and sells them for $429. What is the mark-up, as a percentage?
Katarina [22]

Answer:

10%

Step-by-step explanation:

We have been given that the manager of a store orders model railroad sets that cost $390 and sells them for $429.  

We will use markup % formula for our given problem.

\text{Markup percentage}=\frac{\text{Selling price- Cost}}{\text{Cost}}\times 100

\text{Markup percentage}=\frac{429-390}{390}\times 100

\text{Markup percentage}=\frac{39}{390}\times 100

\text{Markup percentage}=\frac{1}{10}\times 100

\text{Markup percentage}=10

Therefore, markup is 10% of cost.
