Answer:
D. -2 ≤ y ≤ 3
Step-by-step explanation:
This is because range is based on y-values and so the lowest y-value here is -2 and the greatest one is 3, inclusive.
Answer:
4Na + 1O2 > 2Na2O
SF6 > 1S + 3F2
2FE2O3 > 4FE + 3O2
Step-by-step explanation:
1. Identify the Products and Reactants(always do O2 last)
2. determine how many atoms of each element are present on each side of the equation
3. Add Coefficients and never change the subscripts. If there's a coefficient in front of any compound, it is distributed to both elements.
4. find the total number of atoms on both sides of the equation and make sure they equal with each other
Answer:
She ran a total distance of 8,800m or 8.8km
Step-by-step explanation:
In this question, we are asked to calculate the total distance ran by Leilani if at each meet she runs a distance that is exactly equal to a quarter of the total and she competed 22 times during the year.
Firstly, we proceed to calculate the the distance she runs at each relay for her team. We were told she runs a distance equivalent to a quarter.
Mathematically, the distance she runs will be ; 1/4 * 1,600 = a distance of 400 meters
Now, we are told that she ran at 22 different track meets last year. So the total distance she ran will be 22 * 400 = 8,800m or 8.8km
I could be very wrong, but I believe the answer is C
