First, you find the biggest number that you can divide 24, 30, and 12 by. I would go with 6, because it will simplify all the numbers into the simplest forms possible in this equation. Then, divide each number by 6.
24/6= 4
30/6= 5
12/6= 2
The answer:
4 : 5 : 2
Hope I could be of help:)
Tom and Martin worked <u>9 hours</u> this week.
These are their hourly wages:
Tom: $2.15
Martin: $2.50
This means that:
Tom earned 9 x $2.15 in wages, which is equal to $19.35.
Martin earned 9 x $2.50 in wages, which is equal to $22.50.
--------------------
Now, we've been told that Tom and Martin sold $360 worth
of meals but we were not told how much they received in tips.
For all intents and purposes, let's say that they received $n
in tips. 15% of $n in tips would be less than 20% of $n
in tips. Now, Martin is already going to be receiving a higher
wage, and the fact that he is going to be receiving 20% of
$n in tips compounds the logical conclusion that at the end
of the week, he'd be leaving work with more money than Tom.
Answer:
Martin made more money than Tom.
By trig they mean SOH CAH TOA as shown in the picture you do not have the H or hypotenuse so your only choice is TOA
The first number: 3 + x
The second number: x
3 * (3 + x) < 4 * x
If you would like to find the two numbers, you can calculate this using the following steps:
3 * 3 + 3 * x < 4 * x
9 < 4 * x - 3 * x
9 < x
x > 9
Result: The first number is greater than 12 and the second number is greater than 9.
Step-by-step explanation:
the expected value is calculated by multiplying each of the possible outcomes by their probability, and then summing up all these results.
tossing a coin 2 times gives us 4 possible different outcomes (all with the same probability of 0.25) :
head - tail
head - head
tail - head
tail - tail
to have exactly one head is 2 out of these 4 possible outcomes, and the probability is 0.5.
everything else is also 2 out of these 4 possible outcomes, and the probability for that is therefore 0.5 too.
the expected value (from your point of view) is
9×0.5 - 15×0.5 = -$3.00
