Answer:
Barry's kart is faster as he goes 21 Mph while Alan only goes 19.89 Mph.
Step-by-step explanation:
First to get this answer we need to convert feet per minute to miles per hour. So we multiple 1750 feet per minute by 60 to get a hour. This gets up 105000 total feet in a hour. Now we need to divide this by 5280, which is how long a mile is, to get 19.89 miles which is how many miles he travels in a hour making him travel 19.89 mph which is less than 21 making Barry faster.
Answer:
-4w+1
Step-by-step explanation:
Simplify the expression.
The diagram shows the coordinates of the vector. They are:
East-coordinate = 6
North-coordintate = 4
A) To find the magnitude you just use Pythagorean theorem:
c^2 = 6^2 + 4^2 = 36 + 16 = 52 => c = √52 = 7.21
7.21 rounded to the nearest tenth is 7.2
B) To find the direction find the angle using trigonometric ratios:
tan(angle) = 4/6 = 2/3 => angle = arctan(2/3) = 33.69 degrees
That is 33.69 degrees North of East, which is written N 33.69° E
Answer:
They provide guidance for what formulas to use and what steps to take to solve the problem.
Step-by-step explanation:
Different formulas work for different units- there are different formulas for distance, time, density, etc- and also, if a question is in cm but the formula is in km, you have to convert the cm to km to solve the problem. Without units we would not know how to do either of these things.
