Answer:
8 gallons per minute
Step-by-step explanation:
24 gallons in 3 minutes
you divide 24 by 3 which is 8
40 gallons in 5 minutes
you divide 40 by 5 which is 8
the relationship is that in both the answer was 8 as in 8 gallons per minute
A+b=(-3n+2)+(5n-7)
=(5-3n)+(2-7)
=2n-5

Two years ago, Sally had 5,000 dogs in her dog shelter. Now she has 24,575 dogs. The rate of change is 391.5 % increase
<em><u>Solution:</u></em>
Given that Two years ago, Sally had 5,000 dogs in her dog shelter
Now she has 24,575 dogs
To find: rate of change
A rate of change is a rate that describes how one quantity changes in relation to another quantity
<h3><u>Steps to follow:</u></h3>
- First: work out the difference (increase) between the two numbers you are comparing.
- Increase = New Number - Original Number.
- Then: divide the increase by the original number and multiply the answer by 100.
- % change = Increase ÷ Original Number x 100
![\text {rate of change }=\frac{\text { new value }-\text {original value}}{\text {original value}} \times 100](https://tex.z-dn.net/?f=%5Ctext%20%7Brate%20of%20change%20%7D%3D%5Cfrac%7B%5Ctext%20%7B%20new%20value%20%7D-%5Ctext%20%7Boriginal%20value%7D%7D%7B%5Ctext%20%7Boriginal%20value%7D%7D%20%5Ctimes%20100)
![\begin{array}{l}{\text { rate of change }=\frac{24,575-5000}{5000} \times 100} \\\\ {\text { rate of change }=\frac{19575}{5000} \times 100=391.5}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Ctext%20%7B%20rate%20of%20change%20%7D%3D%5Cfrac%7B24%2C575-5000%7D%7B5000%7D%20%5Ctimes%20100%7D%20%5C%5C%5C%5C%20%7B%5Ctext%20%7B%20rate%20of%20change%20%7D%3D%5Cfrac%7B19575%7D%7B5000%7D%20%5Ctimes%20100%3D391.5%7D%5Cend%7Barray%7D)
Thus the rate of change is 391.5 % increase
Answer:
3 km
Step-by-step explanation:
Lets say that you flipped the smaller triangle to be facing the same way as the bigger triangle. To find the X side, we need to do 4.5/1.2 = 1.75. which is the difference between the sides. So then we do 1.75 x 0.8 = 3.
Sorry if I couldn't explain well enough, which is not something I'm good at. I hope you get the question right! Glad I could help! :)
