14 + 7 * 54 / 6 - 7
Use PEMDAS
There are no parenthesis nor exponents so move on to multiplying and dividing work left to right!
14 + 7 * 54 / 6 - 7
14 + 378 / 6 - 7
14 + 63 - 7
77 - 7
70 is your answer
Answer:
18
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Answer: The slope is 1.5. The equation of the line is y=1.5x+3
Step-by-step explanation:
Slope is the "Rise" over the "Run" of a line. The rise is the change in y. The run is the cange in x. Take any two points. I picked (0,3) and (4,9) since they were clearly on whokle number lines. The rise is (9-3) or 6. The run is (4-0) or 4. Rise/Run = 6/4 or 1.5. The y intercept is at 3 (the value of y when x=0). The full line equation is thus y = 1.5x+3.
Answer:
120 MW/hour
Step-by-step explanation:
The formula of the average rate of change between two points in a function is:
Average rate of change (ARC) = f(x2) -f(x1)/(x2-x1)
Let's think the power demad as a function d(x) depending of the hour of the day, so the variable x= hour of the day.
Now we have:
d(5)= 1600
d(8)= 1960
If we apply the mentioned ARC formula = [d(8)-d(5)] MW/(8-5)hour= (1960-1600)MW/3hour= 360/3=120 MW/Hour
Answer:
A=πr2
A=π8^2
A=π* 8* 8
A= 64π
