Average speed=total distance / total time....
s=25/1.5=50/3mph (16 2/3 mph)
So you traveled an average of 2/3 mph greater than your record pace...
Answer:
A.) x/6 = 31/28
Step-by-step explanation:
x = Actual height of Julian
x/6 = 31/28
As 31 is the actual height of the building, you're comparing those.
The cos y = 0.3. The cosine of any angle is the same as the sin of the complement of the same angle.
Answer: $3,276
Step-by-step explanation:
To find the amount of interest needed to be paid, you needed to multiply the amount of money by your interesate rate.
= 3150 x 0.04
= 126
So, we add this extra amount to be paid to the exisiting total
= 3150 + 126
= $3,276
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.
