Answer:
Step-by-step explanation:
Y=UT
Answer:
A
Step-by-step explanation:
1. sqrt5 + 6sqrt5 = (1+6)sqrt5 = 7sqrt5 (answer is D)
2. 4sqrt2 - 7sqrt2 = (4-7)sqrt5 = -3sqrt2 (answer is B)
3. 3sqrt7 - sqrt63 = 3sqrt7 - sqrt7 * sqrt9 = 3sqrt7 - 3sqrt7 = 0 (answer is D)
4. -6sqrt10 + 5sqrt90 = -6sqrt10 + 5*(sqrt10 * sqrt9) = -6sqrt10 + 5*(3sqrt10)
= -6sqrt10 + 15sqrt10 = 9sqrt10 (answer is A)
5. sqrt6*(sqrt 2 + sqrt 3) = sqrt12 + sqrt18 = 2sqrt3 + 3sqrt2 (answer is D)
Answer:
4 feet 2 inches
Step-by-step explanation:
Total Ribbon = 75 feet
Total Students = 18
If equally cut, each student will get the total divided by number of students, that would be:
75/18
That would be:
feet per student
Now, we need the fractional part as inches.
We know 12 inches is 1 feet, so 1/6th feet is:

The fractional part is "2 inches"
Thus,
each piece would be <u>4 feet 2 inches</u>
