Answer:
The amount of gold used in a 200 g 14 gold bracelet is 116 g.
Step-by-step explanation:
Since a 14 karat jewell is stated to have aproximally 58 % of it's weigh in gold we need to take the total weigh of the jewel in question and find that percentage of it's weigh. In order to find that percentage we'll first convert that number into a decimal, we do that by dividing it by 100, so we have 58% = 58/100 = 0.58 we can multiply this value by the weigh of the jewel to find the amount of gold used. So we have:
gold used = total weigh*0.58 = 200*0.58 = 116 g

Answer:
11.00 pm
Step-by-step explanation:
Given that at 11:00 AM a bus left San Jose travelling to Los Angeles at 48 mph. Hence in 4 hours it would have travelled
48x4 = 192 miles
When the bus travelled 192 miles a motorcyclist started in the same direction with speed 72 mph
Difference in speed per hour = 72-48 = 24 mph
TO cover the distance of 72 miles, time taken for the motorcycist would be
192/24 = 8 hours
In 8 hours or at 11.00 p.m. motorcycle will catch upto the bus,
