Answer:
c. 12%
Step-by-step explanation:
40% of the beads are spears, you can convert it to 0.4
30% of the spheres are blue, you can convert it to 0.3
=> probability choosing blue sphere = (0.4 * 0.3)*100(%) = 12%
My explaination may not really clear but the answer is correct. Hope this help!
Answer: the cyclist must wait for 25 minutes until the hiker catches up.
Step-by-step explanation:
Distance = speed × time
The Cyclist was travelling in the same direction along the same path
as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is
20 × 5/60 = 100/60 miles
For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.
Time = distance/speed
Time required by hiker to catch up with the cyclist is
(100/60)/4 = 100/240 hour
Converting 100/240 hour to minutes, it becomes
100/240 × 60 = 25 minutes
180=45x and x is 4 4x45=180
Answer: yes, she can
Step-by-step explanation:
10:13 (ratio) = 0.769
3 (pounds) x 0.769 (ratio) = 2.307 (dollars)
5 (hours) x 2.307 (dollars) = 11.35
