Answer:
Step-by-step explanation:
Let x represent the total number of stdents that has all grades in the school.
There are three grades in the school. One grade has 1/3 of the students, this means that number of students that belongs tho this grade is 1/3 × x = x/3
One grade has 1/4 of the students, this means that number of students that belongs to this grade is 1/4 × x = x/4
Total number of students in both grades would be x/3 +/x/4 = 7x/12
The number of students in the remaining grade would be
x - 7x/12 = 5x/12
fraction of students in the remaining grade would be
(5x/12)/x = 5/12
Answer:
x = 6√6
Step-by-step explanation:
27/x = x/8
x² = 27 × 8
x = √(27 × 8)
x = √(9 × 4 × 6)
x = 3 × 2 × √6
x = 6√6
Answer:
4. 23 in
Step-by-step explanation:
The tower is 1 1/4 feet high, then 8 inches are added. Well, we can't just add those two numbers. We have to change the units! Change everything to inches.
1 1/4 feet is equal to 12 inches + 3 inches = 15 inches, because a foot = 12 inches.
Add 8 inches to 15, and you get 23 inches.
<u>The answer is 4. 23 in. </u>
