15.90 would be your new answer
Answer:
rate = natural log (Total / Principal) / Years
We need 5,000 to become 10,000 in 10 years so,
rate = natural log (Total / Principal) / Years
rate = natural log(10,000 / 5,000) / 10
rate = natural log(2) / 10
rate = 0.69314718056 / 10
rate = .069314718056 which equals
rate = 6.9314718056 per cent

Step-by-step explanation:
Answer: The answer is 190°.
Step-by-step explanation: We are to find the measure of ∠T which lies between 0° and 360° and is co-terminal with an angle of measure -170°.
We know that two angles are said to be co-terminal if one is obtained from the other by either adding or subtracting 360°.
So, angles which are co-terminal with -170° are
-170° + 360° = 190°, -170° - 360° = 530°, etc.
Since 190° lies between 0° and 360°, so measure of ∠T is 190°.
Thus, the answer is 190°.
Let x be equal to Jim's travel time
Let x + 2 be equal to Joan's travel time
distance = speed*travel time
6(x + 2) + 8x = 33
6x + 12 + 8x = 33
14x = 21
x = 21/14 = 3.5
3.5 hrs is the hours that Jim have been running until he met Joan.
Given:
total of 224 visitors
older than 18 paid $12
18 and below paid $8
total collection 2,520
Let l be visitors older than 18 and m be visitors 18 and below.
l + m = 224
12l + 8m = 2,520
l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42 number of visitors 18 and below.
l = 224 - m
l = 224 - 42
l = 182 number of visitors older than 18.
12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520
