Answer:
Each nested carts is of the length of 1.5 feet.
Step-by-step explanation:
Each row has a starting cart that is 4 feet long, and the nested carts are next to it.
It is measured that a row of 13 nested carts has a length of 23.5 feet.
Therefore, the original length of 13 nested carts is (23.5 - 4) = 19.5 feet.
So, each nested cart add to the length of the row, feet.
Again, a row of 18 nested carts to be 31 feet long.
Therefore, the actual added length of 18 nested carts is (31 - 4) = 27 feet.
So, each nested cart add to the length of the row, feet.
So, each nested carts is of the length of 1.5 feet. (Answer)
Answer:
3. A; 4. C; 5. D; 6. D
Step-by-step explanation:
3. By Pythagorean theorem, x^2=100-64=36, x=6
4. By Pythagorean theorem, x^2=81-36=25, x=5
5. Since the triangle is an isosceles, the other side is 4, so the hypotenuse is 4. (the ratio is 1:1:
by Pythagorean theorem)
6. Like Question #5, the ratio is 1:1: since it is an isosceles triangle, the leg is 8.
