Answer: 12 hrs 40 mins
Step-by-step explanation:
The swimming time was 1 hour 25 minutes.
Her biking time was 5 hours longer than the swimming time so it was:
= 1 hr 25 mins + 5 hours
= 6 hours 25 mins
Her running time was 4 hrs 50 mins.
Add them all up to find the amount of time ran. First add up the minutes:
= 25 + 25 +50
= 1 hr 40 minutes
Hours = 1 + 6 + 4
= 11 hours
Total:
= 11 + 1 hr 40
= 12 hrs 40 mins

Answer:
40% reduction
Step-by-step explanation:
To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:
Sale price: 100 - 20 = 80
Last day price: 100 - 25 = 75
Now we need to multiply these two values together, remembering to divide both numbers by 100 first:
80 ÷ 100 = 0.8
75 ÷ 100 = 0.75
0.8 * 0.75 = 0.6
Then multiply by 100 to find the percentage:
0.6 * 100 = 60
60% is the end price, but to find the overall reduction we need to subtract this value from 100:
100 - 60 = 40
So there was a 40% reduction on the price.

Here's how you do it: you find all the distances between the three points and add them together to calculate the perimeter of the triangle. To calculate for the distance between two points, the formula is
d = √[(x2 - x1)² + (y2 - y1)²]
So, just take two points, assign x1 and x2 with corresponding y1 and y2, then you get the answer.
Points: D(1,4), E(3,-2), C(-3,1)
After substituting the answers would be:
DE = 6.3 units
CE = 6.7 units
CD = 5 units
Perimeter = 6.3 + 6.7 + 5
Perimeter = 18 units
It is 7
2*2x = 4x + 2 = 30
4x = 28
x = 7
3.5 years (so 4 years)
2500×0.065 (this gets the amout earned per year) =162.5
568.75÷162.5 (how many years to get the desired amount) =3.5
