The area of a circle:
r - the radius, which is equal to half the diameter d
The first circle:
The second circle:
the second circle has a diameter that is four times the diameter of the first circle.
The ratio of the area of the smaller cirlce to the area of the larger circle:
The ratio is 1:16.
-3 x 13 super easy its all about negative and positives sign
Let x is Jiri's age
2x is Pamela's age
x + 2x = 33
3x =33
x = 33/3
x =11
Answer: Jiri's age is 11
Answer:
Time taken to travel at 3 miles = 1.875
Time taken to travel at 5miles = 1.125
Total distance = 11.25
Step-by-step explanation:
D = speed x time
Time = distance/speed
Time at 3 miles per hour and 5 miles per hour
T1 = d/3
T2 = d/5
Total time = 3 hours
T1+t2 = 3 hours
d/3 + d/5 = 3
= d(1/2+1/5) = 3
d(5+3/15) = 3
d(8/15) = 3
We cross multiply
8d = 45
d = 45/8
= 5.625 miles
Total distance = 2d
2x5.625 = 11.25 miles
Since d is now known
T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes
T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes
Total distance 2xd = 11.25
