Answer:
1. 10 miles
2. 12 feet
Step-by-step explanation:
For question 1, they both walk for two hours so Sara walked 8 hours and her sister walked 6 miles. Since they went 90˚ opposite directions, we have to use the Pythagorean Theorem to find the distance. 8 squared plus 6 squared equals c squared. 64 plus 36 equals c squared. The square root of 100 is 10, so the distance is 10 miles.
For question 2, you also have to do the Pythagorean Theorem. So, since the hypotenuse is 15, we do 15 squared minus 9 squared equals b squared. 225 minus 81 equals b squared. 144 equals b squared. The square root of 144 is 12. The answer is 12 feet. I hope this helped and please mark me brainliest. I spent I lot of time on this!
The prediction of the editor is not correct
Step-by-step explanation:
Step 1 :
Given,
Percentage of email that comes back undelivered = 3%
Number of email the editor sends out = 12181
Number of email predicted by the editor which is undelivered = 433
Step 2 :
To compute the actual number of emails undelivered we need to compute 3% of the emails that is actually sent.
= 3% of 12181 = 0.03 * 12181 = 365.43 which is 366 rounded to the closest integer.
Step 3:
Hence we can conclude that the prediction of the editor is not correct as only 366 undelivered notices are received back as against his prediction of 433 notices.
