For a the answer is: 48 km/hr. For b the answer is: The distance could be longer, so if she took hours she would have to drive faster; or if starter distance she would have driven slower
The answer 280,000 because 4 is closer to 0
Answer:
2√10 km
Step-by-step explanation:
By Pythagoras theorem,
x^2 + 9^2 = 11^2
x^2 + 81 = 121
x^2 = 121 - 81
x^2 = 40
= 4 x 10
x^2 = 2^2 x 10
x = 2√10 km
Answer:
110
Step-by-step explanation:
40% is the same as 40/100, which is equal to 0.4. Therefore, you can write the following equation:
0.4x=44
Divide both sides by 0.4 to isolate x:
x=44/0.4=110
Hope this helps!
