Area of a circle is pi (r)^2
So area of semi circle is 1/2 pi (r)^2
Then area =32 pi or ~100.53
Answer:
Step-by-step explanation:
The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1. :)
In this case, the coefficient is 7.
Answer:
A. 0.80
Step-by-step explanation:
First, you need to find the mean of the cost of Sara's lunches the first week. The mean is the 'average,' and to find the average, add all of your terms and divide by the amount of terms.
Sarah's total cost for the first week was $47.49. Divide by your number of terms (5) for your average daily cost.
This can be rounded to $9.50.
For the next week, Sara spent $4 more in total than the first week. So, add $4 to your total.
Now, divide $51.49 by your number of terms (5) again to find your average for the second week.
This can be rounded to $10.30.
Find the difference.
Sara spent $0.80 more on average.
Answer:
C. y = 2/3x - 2
Step-by-step explanation:
we already have both the y-intercept (b) and the slope (m)
so all we have to do is put it in the slope-intercept form or y=mx+b
y = 2/3x - 2
Answer:
Yes
Step-by-step explanation:
When you simplify 2(x+1). [MULTIPLY]
It comes 2x+1 so it is equivalent to 2x+1
