Answer:
Step-by-step explanation:
Let y represent the distance travelled downwind by the bird from its nest.
Distance = speed × time
A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. Distance covered in travelling downwind is
2 × 18 = 36 miles
On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after 3 hours. It means that the speed at which the bird travelled is 18 - 3 = 15 mph. Also, the distance covered in 3 hours is 36 - 5 = 31 miles. Therefore,
a) distance of the entire trip is
36 + 36 = 72 miles
b) time spent in travelling downwind from its nest is 2 hours
Time for the return part is
3 hours + 5/15 = 3 + 1/3 × 60 minutes
= 3 hours 20 minutes
Total time for the trip is
2 hours + 3 hours 20 minutes
= 5 hours 20 minutes 0 seconds
Answer:
See below.
Step-by-step explanation:
A. k = 50 * 3.6 = 180.
B. The equation is y = 180/x.
C. When x = 75, y = 180/75
= 2.4.
D. Checking C: 2.4 = 180/75 = 2.4. Correct
Answer:
x-1 y-2
x-2 y-2
x-3 y-4
Step-by-step explanation:
graph the points. It should look like a triangle without the bottom.
100 ÷ 16 = 6 remainder 4
So each child will get 6 stickers and we will have 4 stickers left.
Answer: 4 left over
Answer:
42
Step-by-step explanation:
First I'm going to assume that C and A are perpendicular.
Because its perpendicular, this creates a 90 degree angle which can be used to create the following equation.
Reduce
11x = 88
x = 8
We then plug in 8 into the equation 6x - 6 in order to solve for that angle.
6(8) - 6
42
