If, on their own, it takes 6 hours for Person A to complete a task and 9 hours for Person B to complete the same task, then how many hours would it take if they worked together? Estimate your answer to 4 places after the decimal, if necessary.
1 answer:
Answer:
Step-by-step explanation:
A does 1/6 of the task per hour.
B does 1/9 of the task per hour.
Together, they do 1/6+1/9 = 5/18 of the task per hour, finishing in 18/5 hours.
18/5 = 3.6 hours

Answer:
(8,10) is not a solution
Step-by-step explanation:
Cuz it’s not on both inequality shaded part but just one of them and also when we substitute one is true and the other one is false
2x + y _< 8
2(8) + 10 _< 8
18 + 10 _< 8
28 _< 8 false
X + y _> 4
8 + 10 -> 4
18 _> 4 true
Answer:
42.43 ft
Step-by-step explanation:
Please find attached an image of the softball pitch
h² = p² + f² -2x p×f×cos45
h² = 43² + 60² - 2x (43)(60) x 0.7071
h² = 1849 + 3600 - 3648.636
h² = 1800.364
h = √1800.364
h = 42.43 feet
The scale factor is what u multiply the first image by to get the second image. So by dividing the second image by the first image will give u the scale factor. 6 / 1.5 = 4....so there is a scale factor of 4 because 1.5 * 4 = 6
