Many types it just depends on what kind of element for example a chemical element is a certain type of atom
Answer:
4 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (- 2, - 4 ) and (x₂, y₂ ) = (- 2, - 8 )
d = 
= 
= 
= 
= 
= 4
2. The total number of ski trails is 12. That's how many numbers there are in the box.
3. The difference in length between the longest ski trail and the shortest ski trail is the biggest number minus the smallest number in the box. 3 1/8 minus 1 3/8 is 1 and 3/4. So the answer is 1.75 or 1 3/4, whichever one works.
4. There are 3 trails that are 2 7/8 miles long. so You do 2 7/8 times three or 2 7/8 plus 2 7/8 plus 2 7/8. That equals 8 19/40 which is the answer. Ti add them together first turn them into mixed numbers. 2 7/8 is the same as 23/8. 8x3=24. 23x3=69. 69/24 is the same is 8 19/40 through further simplification.
5. 3 1/8 plus 1 3/8 is 4 1/2 or 4.5
6. The shortest ski trail is 1 3/8. 1 3/8 times 3 is 4.125. 4 is greater than 3 which means Sam is automatically right.
The sum of the angle measures in a dodecagon is 1,800 degrees
i hope i helped
E+(e-24)=126
2e-24=126
2e=150
e=75
So (s)he recieved 75 and 75-24=51 emails on those days.
