Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.

Answer:
5 miles
Step-by-step explanation:
Time/speed/distance problems can be worked a number of ways. Here, we want to know the distance walked. We know the total time and the total distance and the two different speeds. So, we can use a variable to represent the value we want to know: w = distance walked (in miles).
The total time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours.
The total time is the sum of times for the two parts of the trip: walking and riding.
walking time = walking distance/walking speed
= w/3
riding time = riding distance/riding speed
= (20-w)/30
The total time is that given above:
w/3 +(20-w)/30 = 13/6
10w +(20 -w) = 65 . . . . . . . . multiply by 30
9w = 45 . . . . . . . . . . . . subtract 20, collect terms
w = 5 . . . . . . . . . . . divide by 9

Answer:
6. 10^3 ten to the third power
7. 10^5 ten to the fifth power
8. not sure
10. 60
19. 20
11-13: not sure
and i can't understand the rest
Step-by-step explanation:
Given that:
A = 63
B = 56
C = 61 (since these angles should be equal to 180)
a =
b =
c = 1/2
sin 63 / a = sin 61 / .5
a = .51 miles
sin 56 / b = sin 61 / .5
b = .47 miles
The correct answers are: 0.51 miles and 0.47 miles. These are <span>the distances from each observer to the sailboat.
