Answer:
9.42 ft
Step-by-step explanation:
We know the diameter is equal to 1.5 ft.
The equation for circumference is 
πr.
Let's insert the numbers we already have.
2(3.14)(1.5)
= 9.42 ft
Step-by-step explanation:
try doing a2+b2=c2 it will help
You can choose from 20 students for the first student, 19 for the second, 18 for the third, ..., 14 for the seventh student.
That gives you 20 * 19 * 18 * 17 * 16 * 15 * 14.
That number would allow you to write the students in different order. Since order here does not matter, any group with the same students in any order is the same group, you need to divide by the number of way you can order 7 items. Divide by 7 * 6 * 5 * 4 * 3 * 2 * 1
(20 * 19 * 18 * 17 * 16 * 15 * 14)/(7 * 6 * 5 * 4 * 3 * 2 * 1) = 77,520
Answer: 77,520
Answer:
28.125 degrees
Step-by-step explanation:
3/8 of 45 is 16.875
45-16.875=28.125
Those two angles are alternate interior angles, so they must be congruent.
3x = 2x + 20
x = 20
