Answer:
Average Speed to complete the journey = 80 km/h
Step-by-step explanation:
Given,
The distance between Sydney and Goulburn = 200 kilometer.
Time to complete the journey = 2 hour 30 minutes
Converting the time into minutes -
2 hour 30 minutes
= (2 x 60) minutes + 30 minutes
= 120 minutes + 30 minutes
= 150 minutes
We know, to determine average speed, we have to divide the distance by time.
Therefore, Speed =
Speed =
Speed = 1.33 km/minutes
Speed = (1.33 km x 60) km/hour (To convert it to hour, we have to multiply by 60)
Average Speed per hour = 80 km/h
2x*(4x^2)*(2x^2+x+7)
8x^3*(2x^2+x+7)
16x^5+8x^4+56x^3
Hope this helps :)
Answer:
k = 16
Step-by-step explanation:
Isolate the variable, k. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Subtract 67 from both sides of the equation:
k + 67 = 83
k + 67 (-67) = 83 (-67)
k = 83 - 67
k = 16
16 is your answer for k.

Answer:
27/250
Step-by-step explanation:
Green grape is 9/25
seedless is 3/10
Since it’s a compound probability you multiple them to get 27/250
82 = (n + 10) + n + [2(n + 10)]
Solve that ad you will have your numbers. Don't forget to simplify the terms first before you start solving.
