Answer:
40 mph <3
Step-by-step explanation:
Trust me, it isn't that bad. Miles per hour is what we would call a rate. In this case, this rate is made up of distance over time. They have given us this distance (1/4 of a mile) and time (22.5 seconds).
First off, lets convert our fraction to a decimal.
1/4 = 0.25
DistanceTime=mph
We must notice that out units for time are different than the rate. Therefore we must convert seconds to hours.
There are 60 seconds in a minute and 60 minutes in an hour.
60 x 60 = 3,600
22.5s×1hour3600s=0.00625hour
Now that we have the correct units, we can do our distance over time formula.
0.25mile0.00625hour=40mph
Sorry, I hope this is correct!!
1. Find the greatest common factor (GCF)
What is the largest number that divides evenly into 4x^2, -16x^4, and 10x^5?
It is 2.
What is the highest degree of x that divides evenly into 4x^2, -16x^4, and 10x^5?
It is x^2.
Multiply the results above, the GCF = 2x^2
2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2x^2(4x^2/2x^2 + -16x^4/2x^2 + 10x^5/2x^2)
3. Simplify each term in parentheses
2x(2-8x^2+5x^3)
Have a nice day :D

Answer:
n = 17°
Step-by-step explanation:
The two angles are split by a 90° angle on a 180° line. This means that 44 and 3n - 5 must add up to 90.
3n - 5 + 44 = 90
Solve out left side
3n + 39 = 90
Subtract 39 from both sides
3n = 51
Divide both sides by 3
n = 17
Thirty-three percent of all students at a high school like beef stew. Put of three hundred students, forty are selected randomly and asked whether they liked beef stew. If liking beef stew is a success, the probability of a failure for this binomial experiment would be 0.67. The answer would be letter D.
