1 answer:
Answer:
The play started at 5:10 PM.
Step-by-step explanation:
We are given the following in the question:
Length of first act = 45 minutes
Length of intermission = 55 minutes
Length of second act = 1 hour and 10 minutes
1 hour = 60 minutes
Thus, length of second act =
The second part ended at 8:00 PM. We have to find the starting time of play.
Starting time of play =
Thus, the play started at 5:10 PM.

Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question, we have that:
We have to find P. So

Answer:
Option D is correct.
13x = 39
Step-by-step explanation:
The system of equation is given:
....[1]
.....[2]
Multiply equation [1] by 5 to both sides we have;
.....[3]
Using elimination method:
Add [2] and [3] equations to eliminate y and solve for x, we have;
Divide both sides by 13 we get;
x = 3
Substitute x in [1] we have;
2(3)-y = -4
6-y = -4
Subtract 6 from both sides we have;
-y = -10
Divide both sides by -1 we have;
y = 10
⇒Solution: (3, 10)
Therefore, an equation can replace 3x+5y = 59 in the original system and still produce the same solution is,
13x = 39
Answer:
a) h'(t)= (6cos3t,-9sin3t,3cos3t)
b) t=0.93994736+πn/3
c) Magnitude of h(t) is 3 which is a constant, so h(t) lies on a sphere
