Clare has berries (b). Rasheed has 6 times more berries that Clare has, and Rasheed also has _ amount of watermelons. How much fruits does Rasheed have in all?
Answer: 0.8
Step-by-step explanation:
given data:
uncertainity = 4g
bias = 2g
solution:
σX =0.2 and σY = 0.4
σcX
= 3σX
= 4(0.2)
= 0.8
An expression that represents how the four friends would split a bill of ’x’ dollars is: x/4
If their total bill was $124.00:
124/4 = 31
Each friend should pay $31.00
Distance = rate*time
distance/time = rate
The race course is 3 miles around and Jeff does it twice, so the distance he goes = 2*3 miles = 6 miles.
He takes 20 minutes to go around once and 25 minutes to go around the second time, so the total time = 20 min + 25 min = 45 min.
His speed is miles per hour, not miles per minute, so convert 45 minutes to a hours:
45 min/60 min = 0.75 hours <span>distance/time = rate = 6 miles/0.75 hours = 8 mph</span>
