Answer:
41,43,47
Step-by-step explanation:
The prime numbers between 30 and 45 are 31, 37, 41, and 43.
Answer:
a ≤ 20/3
Step-by-step explanation:
Subtract 4 from both sides, obtaining:
-3a ≥ -20. Dividing both sides by -3, we get a ≤ 20/3.
Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.
Nana's age: 10 years
Step-by-step explanation:
Here we call:
J = Jennifer's age
L = Laurel's age
N = Nana's age
We have the following information:
- Jennifer is twice as old as laurel, so
J = 2L (1)
- Laurel is 4 years younger than Nana, so
L = N - 4 (2)
- Nana is 2 years younger than Jennifer, so
N = J -2 (3)
Substituting (2) into (1),
J = 2(N-4) = 2N - 8
And substituting this into (3) and solving for J, we find Nana's age:
N = (2N-8) - 2
N = 2N - 10
N = 10
Which means that Jennifer's age is:
J = N + 2 = 12
And Laurel's age is
L = J/2 = 6

Answer:
(Marlins, 6.76×10^5), (Pirates, 9.68×10^5), (Angels, 1.87×10^6), (Cardinals, 1.98×10^6)
most: Cardinals
Step-by-step explanation:
First, you compare exponents. Higher positive powers are larger. 10^5 < 10^6.
If the exponents are the same, you compare the mantissas. These are compared in the usual way. 6.76 < 9.68, and 1.87 < 1.98.
Of course, the team with the greatest attendance is the one that is last on the least-to-greatest list.
