1 1/4 per month
12 months per year
1 1/4 * 12 =
5/4 * 12/1 = 60/4 = 15
they get 15 days per year
When you're writing things in scientific notation, the new spot for the decimal number always goes in between the first and second numbers that are not zeroes. For this problem, it'd be 1.4. Then, count how many times the decimal place moves to get to the new spot (#power of ten), which in this case is 4 times. The way I remember this next part is that if it has a negative exponent, the number you get when you solve is really small, so therefore the answer is 1.4×
(10^-4)
1600 children and 1400 adults attended
<h3>How to determine the number of adults?</h3>
Let the children be x and adult be y.
So, we have the following equations:
x + y = 3000
1.5x + 5y = 9400
Make x the subject in x + y = 3000
x = 3000 - y
Substitute x = 3000 - y in 1.5x + 5y = 9400
1.5(3000 - y) + 5y = 9400
Expand
4500 - 1.5y + 5y = 9400
Evaluate the like terms
3.5y = 4900
Divide both sides by 3.5
y = 1400
Substitute y = 1400 in x = 3000 - y
x = 3000 - 1400
Evaluate
x = 1600
Hence, 1600 children and 1400 adults attended

Answer:
x=-1
Step-by-step explanation:
since XY is a straight line, XM = MY
so, 5x+8=9x+12
4x=-4
x=-1
The company picnic cost $ 1300 for 80 employees
<em><u>Solution:</u></em>
Given that cost of a company picnic varies directly as the number of employees attending the picnic
Let "c" be the company picnic cost
Let "n" be the number of employees attending the picnic
Therefore,


Where "k" is the constant of proportionality
c = kn ---------- eqn 1
<em><u>Given that company picnic costs $487.50 for 30 employees</u></em>
Therefore substitute c = 487.50 and n = 30

<em><u>How much does a company picnic cost for 80 employees?</u></em>
Substitute n = 80 and k = 16.25 in eqn 1

Thus $ 1300 is the cost for 80 employees
