Question 553504: Meteorologists can approximate the duration of a storm by using the formula T=.07D^3/2, where T is the time in hours that a storm of diameter D (in miles) lasts.
The National Weather Service reports that a storm 4 miles in diameter is headed toward New Haven. How long can the residents espect the storm to last?

Question 553666: 2. The equation gives the distance, D, in miles that a person can see to the horizon from a height, h, in feet.
d. Solve this equation for h.
e. Long’s Peak in Rocky Mountain National Park, is 14,255 feet in elevation. How far can you see to the horizon from the top of Long’s Peak? Can you see Cheyenne, Wyoming (about 89 miles away)? Explain your answer.

Question 554491: using the formula s=2sqrt5x (I am having trouble inserting the radical sign so i used "sqrt" i know that is not right everything i used would not work). We will call the speed S (in miles per hour) and x is equal to the length of a skid mark in feet.
What is the speed of a car that has left a skid mark with a length of 61.25ft?
What is the speed of a car that has left a skid mark with a length of 320ft?
How long is the skid mark left by a car that was traveling 70 mph when involved in an accident?

Question 554557: Need help solving the following problem.
y/srt7 + sqrt3
If we can't have radicals in the denominator, we need to rationalize the denominator to multiplying the fraction.
sqrt7 - sqrt3/sqrt7 - sqrt3
(y/sqrt7 + sqrt3)(sqrt7 - sqrt 3/sqrt7 - sqrt3) We would need to multiply each term

Question 559243: I am so confused on how to add and subtract radical expressions. Please help.
√2 + 3√2 - 5√3
√5 + 4√25 - 3√5
√50 + √27 - 2√5 + 7√3
I really need to be walked through the steps on how to solve these problems.

Question 561329: sqrt(x-6)+3=sqrt(x)
does this have a real solution?
first i subtracted the 3 over, squared both sides and ended up with x=(25/4) but when i plug that in, it was not a true statement.
then i started over and squared both sides like the original problem shows and got the square root equal to a negative so that would be "no real solution".
thank you for looking at this!!
