Answer: the eastbound train had travelled 12 miles
Explanation: using Pythagoras theorem, we know that
X^2 = a^2 + b^2
Where ^ stands for raised to power.
Let
a stand for the train going towards North and
b stands for the train going towards east.
X stands for the total distance between train a and b = 20 miles.
By Pythagoras rule
X^2 = a^2 + b^2
20^2 = 16^2 + b^2
400 = 256 + b^2 so that
b^2 = 400 - 256 = 144
b = √144
b = 12 miles.
Answer:
4(8x-3.2)
Step-by-step explanation:
A. h = 30Ft * 1.26cm/Ft = 37.8 cm. = Ht. of the model.
37.8cm * 1toothpick/6.3cm = 6 Toothpicks
B. 37.8cm/7.6 = 4.97 hope this helped.
Answer:
2/5
Step-by-step explanation:
= -5x - x = 2 + x
= -5x - x - x = 2
= x - x - x = -2/5
= -x = -2/5
= x = 2/5
