Answer:
46 1/5 inches tall
Step-by-step explanation:
We know each board is 2 1/5 inches high
Change this to an improper fraction
2 1/5 = (5*2+1)/5 = 11/5
Multiply this by the number of boards
11/5 * 21 = 231/5
Change this back to a mixed number
5 goes into 231 46 times
46*5 = 230 there is 1 left over
46 1/5 inches tall

Step-by-step explanation:
A linear function has the form
y = mx + b ( m is the slope and b the y- intercept )
B
the graph has a constant rate of change , measured by the slope m of the linear function.
Answer:
Step-by-step explanation:
Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.
That can be written as
x^(1/2)
...and when you take an even root of a negative number, there is no real answer. (2 is an even number).
Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.
So, A and C are the answer choices to select.
