Answer: 22 signs
Step-by-step explanation:
First find out how many feet are in a mile.
A mile = 5,280 feet
There are signs every 240 ft so the number of signs are:
= 5,280/240
= 22 signs
<em>There is a sign at the beginning and one at the end both of which are already account for in the 22.</em>
The equation of the given circle is 
Step-by-step explanation:
Step 1:
The equation of a circle with its center at (h, k) and a radius of r is given by
The h value is the x coordinate and the k value is the y coordinates, so (h, k) is (6, -9).
The radius is given as 10 so 
and 
Step 2:
By substituting the values we know, we get
So the equation of the given circle is
Answer:
40% chance
Step-by-step explanation:
Take the number of horses total and divide the number of bay horses.
<span>1/2+(-2/3)
Multiply until both fractions have the same common denominator
3/6 - 4/6
Subtract the numerator but NOT the denominator
Final Answer: -1/6</span>
Answer:
(4x -14)/3
Step-by-step explanation:
Assuming you intend mixed number coefficients, only the coefficients of x can be combined.
(-2 1/4)x +(3 7/12)x -(4 2/3) = x(-2 1/4 +3 7/12) -(4 2/3)
The mixed numbers are added in the usual way.
(-2 1/4) +(3 7/12) = (-2 +3) +(-1/4 +7/12) = 1 +(-3/12 +7/12) = 1 4/12 = 1 1/3
So the expression simplifies to ...
(1 1/3)x -(4 2/3)
This might be better written as ...
(4x -14)/3

<em>Comment on mixed numbers</em>
It is hard to write mixed numbers so they can be properly interpreted in an algebraic expression. In general, they are better written as improper fractions or as decimal numbers (if the decimal terminates).
