The following lab team that has an unresolved problem on their hands is team 2 in which they calculated 0.395 J/gºC since they have higher percent error compared to the other team which only has 0.390 J/gºC. So the answer would be letter B - <span>team 2: calculates 0.395 J/gºC.</span>
Answer:
The ratio is 15:5 or 3:1. If Marianne is 3 years old, her brother is 1. And it is proportional...
Step-by-step explanation:
Answer:
The lengths are 5, 12, and 13.
Step-by-step explanation:
Let x represent the shorter leg of the triangle. Since the other leg is 7 cm more, the longer leg is x+7. Since the length of the hypotenuse is 3 cm more than double that of the shorter leg, the hypotenuse is 2x+3.
The Pythagorean Theorem may be used to find the lengths.

a, b are the short and long lengths and c is the hypotenuse

(The length cannot be negative)
The shorter leg, x, is 5 cm. Since the longer leg is x+7, it is 12 cm. Since the length of the hypotenuse is 2x+3, the hypotenuse is 13 cm.
The number is 5. 27-12=15/3=5 is how you get the answer.
Just multiply 42 by 10 and that gives you 420 , so the real car has a length of 420cm or 4.2 metres :)
