We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:
Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:
On plotting the series, the result will be like this:
Answer: it will take them 2.22 hours working together.
Step-by-step explanation:
It takes Destiny y 4 hours to file all the daily paperwork. This means that unit rate of Destiny would be
1/4 per hour.
It takes Susan 5 hours to file the same paperwork. This means that unit rate of Susan would be
1/5 per hour.
If they work together, they would work at their own individual rates. This means that their individual rates are additive.
Let t represent the time it will take them if they worked together. Since their combined rate is additive Therefore,
1/4 + 1/5 = 1/t
9/20 = 1/t
t = 20/9 = 2.22 hours
<span>It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)

Answer:
$0.60
Step-by-step explanation:
2 • 4 = 6
6 • 0.10 = 0.60
Im not too sure so dont take my word.
But if you're rounding the fraction to half or whole.
I would round down from 8/14 , to 7/14.
Which 7/14 simplified is 1/2
Your answer is 7/14 i believe
