In aboard game you determine the number of spaces you msy move by spinning a spinner and rolling a die. The spinner has three regions: half of the spinner is marked"5" and the other half is equally divided between "10" and "20". The six faces of the die show 0,0,1,2,3,and 4 spots. When its your turn, you spin and roll, adding the numbers together to determine how far you may movefind the mean and standard deviation of the spiner results after you create a probability model for the outcome on the spinner

Both planes leave from Kansas City at the same time.
Plane A flies due West.
Plane B flies due South.
After 2.5 hours, how far is Plane A from Plane B?
A. 1,425.0
B. 1,322.0
C. 1,258.5
Answers
The distance between Plane A from Plane B is,
⇒ 1,425.0 m
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
Speed of Plane A = 450 mph.
Speed of Plane B = 350 mph.
And, Both planes leave from Kansas City at the same time.
Here, Plane A flies due West.
And, Plane B flies due South.
Now, Distance cover by plane A in 2.5 hours is,
⇒ 450 × 2.5
⇒ 1125 m
And, Distance cover by plane B in 2.5 hours is,
⇒ 350 × 2.5
⇒ 875 m
Thus, The distance between Plane A from Plane B is,
⇒ √1125² + 875²
⇒ 1425.0 m

You would use distance=rate•time to solve:
450 • 2.5 = 1125
350• 2.5 = 875
Since plane A is going west and B is going south, they form a right triangle, so you can use the Pythagorean theorem to solve for the distance between them, which we will represent as x:
1125² + 875² = x²
1265625 + 765265 = x²
2030890 = x²
Once you square root x, it's about 1425.09298, which is closest to answer A, 1425.0

Answer :
You can use commutative property or can not be .It is not necessary to use it for given addition of integers.
Step-by-step explanation:
We are given that an expression
By simplfy simply without using commutative property
Because minus minus is plus then all integers will be added.
Simplfy by using commutative property
(Commutative property a+b=b+a)
The answer should not change .Hence, if you want use commutative property to change the order of the integers then answer does not effected.So, you can use it or can not be .
