Answer:
Step-by-step explanation:
It takes Lucas 3 hours to cycle from his home to his friend’s village:
3 hours • (a certain speed) = distance in miles
If he travels 5mph slower, it will take him 1.5 hours longer:
4.5 hours • (the same speed - 5mph) = the same distance in miles
4.5 • (x - 5) = 3x
4.5x - 22.5 = 3x
1.5x = 22.5
x = 15mph
3hours • 15mph = 45 miles
C. 19.42% because you subtract 389.85 from 314.15 which equals 75.7. So then set it up like an algebraic equation. 389.85x=75.7 divide 75.7 by 389.85 to find the decimal. Then you have to move the decimal to the right two places, since it is a percentage. And then round your answer, so c. 19.42% is your answer. Hope this helped! :)
(12x5)2+(12x6)2+(6x6)2 will give you the answer. (Subtract 24 from the answer when done)
Equilateral triangle- Where each angle of the triangle is measured equally.
Scalene triangle- A triangle where all angles are unequal.
Isosceles triangle- A triangle where two angles are equal.
Right triangle- A triangle with a right angle or 90° angle.
Now your question is what is the best triangle. That is an opinion question so I can't say. But out of the triangles above you could pick which one you think is the best :)
