Answer:
98.518 repeating prercent
Step-by-step explanation:
2 out of 135 can also be written as 2/135
2 divided by 135 is 0.014814814814
that number is the percentage of failures
100% in decimal form is 1.00
1.00 subtracted by the percentage of failures is the percentage of successes
which is .98518518518, 518 repeating move the decimal over 2 and you got the percentage 98.518 repeating
Answer:
He drove to pick Jack at a speed of 16.25mph
Step-by-step explanation:
In this question, we are trying to calculate the speed at which Mathew drove to pick up his cousin Jack.
Firstly, we need to calculate some stuffs.
like the total number of distance traveled? That is simply 8 miles + 11 miles = 19 miles! keep this!
Now, we need to know the total average speed. This is the total distance traveled over the time taken. The time taken is 24 minutes, let’s have this in hours. That would be 24/60 = 0.4 hours
The total average speed is thus 19 miles/ 0.4 hours = 47.5 mph
Now let’s go get the speed he drove to Jack!
directly from the question, we were told that the speed to the mall is 15mph faster. This means if the speed he took to fetch Jack was x, the speed to the mall would be x + 15
so this means;
x + x + 15 = 47.5
2x + 15 = 47.5
2x = 32.5
x = 32.5/2
x = 16.25 mph
The formula for the area of a triangle is 1/2(base×height)
30×27=810
810×1/2=405
