Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .
<u>Step-by-step explanation:</u>
Here we have , Leanne runs a lap in 12 minutes. Kory runs a lap in 9 minutes. We need to find out that If they both start running at 10 am, at what time will they both cross the start together again . Let's find out:
Kory runs a lap in 9 minutes and , Leanne in 12 minutes , in order to find at what time will they both cross the start together again we will find LCM of 9 & 12 :
⇒
⇒
So ,LCM of 9 & 12 is 36 .That means Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .
In clear way , Kory will run race as :
1st lap = 9 minutes
2nd lap = 18 minutes
3rd lap = 27 minutes
4th lap = 36 minutes , i.e. at 10:36 am he'll complete his 4th lap
For , Leanne
1st lap = 12 minutes
2nd lap = 24 minutes
3rd lap = 36 minutes i.e. at 10:36 am he'll complete his 3rd lap .
This means Kory & Leanne will meet at 10:36 am completing there 4th and 3rd lap respectively .
Answer: 60 % - percent of increase
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Original number of cups: 5
</em>
- <em>New number of cups: 8
</em>
For the first part, because the original number of cups increases, the percent of change is an increase.
To find the number:
(new number -original number ) / (original number) =
Replacing with the values given:
(8-5) /5 = 0.6 (decimal form)
To obtain the percentage we have to multiply it by 100:
0.6 x 100 =60%
In conclusion, we have a 60 percent of increase.

Answer: V =
Step-by-step explanation: A solid formed by revolving the region about the x-axis can be considered to have a thin vertical strip with thickness Δx and height y = f(x). The strip creates a circular disk with volume:
V = Δx
Using the <u>Disc</u> <u>Method</u>, it is possible to calculate all the volume of these strips, giving the volume of the revolved solid:
V =
Then, for the region generated by y = - x + 4:
V =
V =
V =
V =
V =
The volume of the revolved region is V =
84 miles I would think
Explanation:
14 whales in all, each travelled 6 miles.
14x6=84
Hope I helped :)
