Answer:
Girl's basketball team has more seniors
Step-by-step explanation:
A varsity boy's basketball team has ratio of seniors to juniors that is 7:4.
Let there are 7x seniors and 4x juniors in boy's basketball team.
ATQ,
7x+4x = 12
11x = 12
x = 12/11
Seniors = 
The varsity girl's basketball team has a ratio of seniors to juniors that is 3 to 2.
Let there are 7x seniors and 4x juniors in girl's basketball team.
3x+2x = 12
5x = 12
x = 12/5
Seniors = 
As we can see that girl's basketball team has more seniors as compared to the boy's team.
Answer:
Water remaining in the pool after 141 days = 14,505 gallons
Step-by-step explanation:
Total number of gallons of water in the pool = 15,069
Rate of leakage of water = 4 gallons per day
Using unitary method
1 day leakage of water from the pool = 4 gallons
∴ In 141 days leakage of water from the pool will be =
gallons
After leaking 564 gallons of water, total gallons of water that will remain in the pool will be =
gallons
If Lana's age is L, her youngest sister is L/2 (or 0.5L) and the twins L-2. Add all these together (remember that there are two sisters who are L-2 years old):
0.5L + L-2 + L-2 + L = 45
Simplify the L's by adding them all together, we get:
3.5L - 2 - 2 = 45
3.5L - 4 = 45
Now add 4 to both sides:
3.5L = 49
Now divide both sides by 3.5
L = 49/3.5 = 14. Now we know that Laura is 14, so her youngest sister must be 7.
