The order of operations is PEMDAS. So it would be 8.4 +(13.1 - 0.6) = 8.4 + 12.5 = 20.9
16. i’m pretty sure cause the ratio would be 42/24 28/x if you divide PQ by LM, the answer is the same number you would use to divide LM to get MN and finish your ratios
The number of ways that the company can choose four workers is 40920 ways.
<h3>How to calculate the number?</h3>
From the information, the building company employs 3 laborers 12 joiners 8 electrician 4 plumbers. The total number of workers will be:
= 3 + 12 + 8 + 4
= 27 workers
It should be noted that combination will be used to choose the 4 workers. This is illustrated as
Combination formula
ⁿCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
where n = 33
r = 4
ⁿCr = n! / ((n – r)! r!)
³³C₄ = 33! / (33 - 4)! 4!
= 33! / 29! 4!
= 33 × 32 × 31 × 30 / 4 × 3 × 2
= 40920 ways

I believe it’s a trapezoid but i’m not too sure... sorry :((
Martha is indeed right when she states that -6 is a rational number. Just like the name implies, a rational number is a number that can be written as a/b with b not equal to 0. Since -6 can be written as -6/1, and since that is a ratio, that is why -6 is a rational number.
