In a class of 147 students, 95 are taking math(m), 75 are taking science (s), 52 are taking both math and science. What is the p

Dmitriy789 [7]

Subtract 52 from m, s, and the total amount of students.. 52 is the amount of students that would take both math and science. m now equals 43, s now equals 23, and the total students remaining is 95.

Since the criteria wants you to exclude students that take math or science, add m and s together.

$43 + 23 = 66$

This is the total amount of students that take math or science.

To find the probability of picking a student that doesn't take math or science, subtract 66 from the total amount of students.

$95 - 66 = 29$

Take this amount and divide by the total amount of students again.

$\frac{29}{95} = 0.3052$

Convert the decimal into a percentage.

$0.3052 = 30.52$ %

There is a 30.52% chance of picking a student that doesn't take math nor science.

Ten minutes after he left his home, Gerald was 40 miles from his grandmother’s house. Then, 22 minutes after he left, he was 34

Svetlanka [38]

After 10 minutes, he's 40 miles away. After 22 minute, he's 34 miles away. Therefore, in those 12 minutes between, he covered 6 miles. We can make a ratio out of this: 6/12 = 0.5, so he is walking at a rate of 0.5 mi/min (miles per minute). Finally, we can set x/90 equal to 0.5/1 because he is walking at the same rate the entire time. Cross multiply to solve for x. Finally, you get that he had to travel 45 miles in 90 minutes, so his home is 45 miles away from his grandmother's.
