Answer:
The correct answer is B. It will take them 7.2 hours.
Step-by-step explanation:
Given that to collect data on the signal strengths in a neighborhood, Briana must drive from house to house and take readings, and she has a graduate student, Henry, to assist her, and Briana figures it would take her 12 hours to complete the task working alone, and that it would take Henry 18 hours if he completed the task by himself, to determine how long will it take Briana and Henry to complete the task together the following calculation must be performed:
1/12 + 1/18 = X
18 / (12 x 18) + 12 / (18 x 12) = X
30/216 = X
5/36 = X
36/5 = 7.2
Therefore, they will be able to finish the task in 7.2 hours.
Answer:
The midpoint is (2.5, 3.5)
Step-by-step explanation:
The midpoint is the average of the coordinates
x = (x1+x2)/2 and y =(y1+y2)/2
x = (2+3)/2 = 5/2 = 2.5
y = (3+4)/2 = 7/2 = 3.5
The midpoint is (2.5, 3.5)
To add two three digits number to form a three digit number, the 3 digit number to be added should be less than 500 because 500 + 500 gives 1000 which is a four digit number.
In this case, there are many possibilities of creating a three digit number from 2 three digit number.
Example :
462 + 395 = 857
200 + 350 = 550
