Answer:
They both would cross each other again in the next 5 minutes
Step-by-step explanation:
The first thing to do here is to calculate the lowest common multiple of the average speed of both drivers.
That would be the lowest common multiple of 1.2 miles per minute and 1.8 miles per minute.
That would be 3.6 miles per minute.
Now to get the time at which they would cross each other again, we simply divide the total distance around the circular track by the lowest common multiple of their average speed.
That would be 18/3.6 = 5
This means they would cross each other again in the next 5 minutes
Answer: 97.5
Step-by-step explanation:
Mean is calculated as total sum of values in a data set ÷ number of values in a data set
Given the data set below, add the values in the data set then divide by number of values in the data set (6)
Mean = 98 + 99 + 100+ 90 +98 +100/6
=585/6
=97.5
I hope this helps. Mark as brainliest answer please
Answer: the second one
Step-by-step explanation:
Answer:

Step-by-step explanation:
Please find the attached image for the quadrilateral QRST.
We have been given that
. We are asked to find the area of quadrilateral QRST.
Upon looking at the image of quadrilateral QRST, we can see that quadrilateral QRST is a kite as it has one pair of diagonally opposite equal angles (98 degrees).
We know that area of kite is equal to half the product of its diagonal.
We can see from our image that QS and RT are diagonal of kite, so the area of quadrilateral QRST would be:




Therefore, the area of quadrilateral QRST is 216 square units.
