Trisha needs to make at least 50 gift bags for an event. Each gift bag will contain at least 1 thumb drive or 1 key chain. She w ants to use at least 5 times as many key chains as thumb drives. She has 25 thumb drives and 200 key chains. Let x represent the number of key chains. Let y represent the number of thumb drives.
Which inequalities are among the constraints for this situation?
Select each correct answer:
A. y≤25
B. x+y≥50
C. x+5y≤50
D. x≥5y
E. x≤5y
2 answers:
Answer: answers B and E and C are correct
Answer:
E. x ≥ 5y
A. y ≤ 25
B. x + y ≥50
Step-by-step explanation:
Let x represent the number of key chains.
Let y represent the number of thumb drives.
As we know that:
She wants to use at least 5 times as many key chains as thumb drives <=> x ≥ 5y
<=> y ≤ 25
Trisha needs to make at least 50 gift bags for an event. Each gift bag will contain at least 1 thumb drive or key chain <=> x + y ≥50
So inequalities are among the constraints for this situation are:
x ≥ 5y
y ≤ 25
x + y ≥50

Given the radius is, r = 16 in,
The expression for the circumference of a circle is,
Therefore, we have,
Thus, the circumference of the circle is 100.48 in.
Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978
