Answer:
820 feet
Step-by-step explanation:
We can use the rule of three in this scenario since this is a ratio problem with one unknown. To do this we simply multiply the diagonal values and divide by the final value. We know that there are a total of 3280.84 ft in a single kilometer, therefore...
1 km == 3280.84 ft
0.25 == x
(0.25 * 3280.84) / 1 = 820.21
Now we can see that there are 820.21 ft in the 0.25 kilometers. If we round this to the nearest foot we would round down to a total of 820 feet.
Answer:
x=9
Step-by-step explanation:
3.5x - 11 = 20.5
Add 11 to each side
3.5x - 11+11 = 20.5+11
3.5x = 31.5
Divide each side by 3.5x
3.5x/3.5 = 31.5/3.5
x =9
