Answer: Juan can travel 19 miles in 2.4 hours at a speed of 8 miles per hour
Step-by-step explanation:
Juan roller skates at the constant speed of 8 miles per hour. Distance travelled is expressed as
Distance = speed × time
Therefore, the distance that Juan can travel in 2.4 hours is
Distance = 2.4 × 8 = 19.2 miles
Approximating to the nearest whole number, it becomes 19 miles
Answer:
His mark, as a percentage, was of 40%.
Step-by-step explanation:
Mark as a percentage:
His mark as a percentage is the number of questions correct multiplied by 100% and divided by the number of questions.
In this problem:
60 questions correct out of 150. So
60*100%/150 = 40%
His mark, as a percentage, was of 40%.
Answer:
2/3 inch
Step-by-step explanation:
12 divided by 8
W+y=25 and 9.95w+11.5y=276.65
solve for w in equation one:
w+y=25
w=25-y
then substitute w in equation two and solve for y:
9.95w+11.5y=276.65
9.95(25-y)+11.5y=276.65
1.55y+248.75=276.65
1.55y+248.75-248.75=276.65-248.75
1.55y=27.9
1.55y/1.55=27.9/1.55
y=27.9/1.55=18
y=18
then substitute y=18 into the first equation to solve for x:
w+y=25
rewrite as w=25-y y=18
w=25-18
w=7
then are answer is w=7 and y=18
