CORRECT ANSWER: 15,190
50%. students (in percent) who passed the second exam also passed the first exam.
Let's imagine that there are 100 kids in the teacher's class. We know that 40 of them passed BOTH tests, and 80 passed the second test.
Because if they weren't, they wouldn't have passed the first test and consequently wouldn't have passed both, we can be sure that the group of students who passed BOTH tests is only made up of the 80 who passed the second test.
Thus, both tests were passed by 40 of the 80 pupils who passed the second one:
40/80 = 1/2 = 50%.

Answer:
264 ft/sec
Step-by-step explanation:
We need to use the conversion factors
5280 ft/ 1 mi, 60 min/ 1 hr , and 60 sec/1 min
180 miles 1 hour 1 min 5280 ft
----------------- * ----------------- * ------------ * ---------------
hour 60 minutes 60 sec 1 miles
The hours, minutes and miles cancel are we are left with ft/sec
180 *5280 ft
----------------- * -----------------
60*60 sec
264 ft/sec
Answer:
To calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. * i didnt know what to put so i put this*
To find volume, multiply length x width x height.
4 1/2 x 5 x 3 1/4
4.5 x 5 x 3.25 = 73.125
1/4 = 0.25
Divide the total of the large cube to the small cube.
73.125/0.25 = 292.5
292 and 1/2 of the small cube(s) are needed to fill the right rectangular prism.
