A 1 mile hiking path has signs placed every 240 ft there are signs at the beginning of the path and the end how many signs are t
dlinn [17]

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>

Write an equation of the circle with center 6.-9) and radius 10!
Makovka662 [10]

The equation of the given circle is (x-6)^{2}+(y+9)^{2}=100.

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

(x-h)^{2}+(y-k)^{2}=r^{2}.

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 r =10 and r^{2} = 100.

Step 2:

By substituting the values we know, we get

(x-h)^{2}+(y-k)^{2}=r^{2} = (x-6)^{2}+(y-(-9))^{2}=10^{2}.

So the equation of the given circle is

(x-6)^{2}+(y+9)^{2}=100.

What is -2 1/4x+3 7/12x-4 2/3 simplified
lesya [120]

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).
