Answer:
106.1 ft/s
Step-by-step explanation:
You know the diagonal of a square is √2 times the length of one side, so the distance from 3rd to 1st is 90√2 feet ≈ 127.2792 ft.
The speed is the ratio of distance to time:
speed = distance/time = 127.2972 ft/(1.2 s) ≈ 106.1 ft/s.
_____
In case you have never figured or seen the computation of the diagonal of a square (the hypotenuse of an isosceles right triangle), consider the square with side lengths 1. The diagonal will cut the square into halves that are isosceles right triangles with leg lengths 1. Then the Pythagorean theorem can be used to find the diagonal length d:
d² = 1² + 1²
d² = 2
d = √2
Since this is the diagonal for a side length of 1, any other side length will serve as a scale factor for this value. A square with a side length of 90 ft will have a diagonal measuring 90√2 ft.
Answer:
The percentage increase without baggage fee=25%
The percentage increase with baggage fee=41.66%
Step-by-step explanation:
Given the cost of the airline ticket two weeks ago is $300 and The present airline ticket is $375
We know that when a quantity increases from x to y then The percentage increase is equal to 
Here the percentage increase = 
=25%
Now the airline charges an extra $50 baggage fee which means teh present value of the airline ticket is $375+$50=$425
the percentage increase = 
=41.66%
The sales tax for a item was $6.20 and it cost $310 before tax. Find the sales tax rate. Write your answer as a percentage.

B. 1.08mL
1 lb = 2.2 kg
5 lb = 2.27 kg
2.27kg × 12mg = 27.24 mg
Divide 27.42 mg by 2.5 = 10.896mg
Now change the mg to mL
10.896 ÷ 10 = 1.0896
