Answer:

-18 1/5-(-2 3/5)=-15 3/5

-52.89-(-25.63)=27.26

-96 2/9- 24 4/9= -120 2/3

49.40-(-85.63)= 135.03

A circular pool measures 10 feet across. one cubic yard of concrete is to be used to create a circular border of uniform width a
mina [271]

we know that

1 ft is equal to 12 in

1 cubic yard is equal to 27 cubic​ feet

Step 1

<u>Find the area of the circular border of uniform width around the pool</u>

Let

x---------> the uniform width around the pool    

we know that

The diameter of the circular pool measures 10 feet

so

the radius r=5 ft

the area of the circular border is equal to

A=\pi *(5+x)^{2}- \pi *5^{2} \\A= \pi *[(x+5) ^{2}-5^{2} ] \\ A= \pi * [x^{2} +10x]

step 2

volume of the concrete to be used to create a circular border is equal to

V=1 yd^{3}-------> convert to ft^{3}

V=27 ft^{3} -------> equation 1

the depth is equal to 4 in-------> convert to ft

depth=4/12=(1/3) ft

volume of the concrete to be used to create a circular border is also equal to

V=Area of the circular border*Depth

V= \pi * [x^{2} +10x]*(1/3) -------> equation 2

equate equation 1 and equation 2

27=\pi * [x^{2} +10x]*(1/3) \\ x^{2} +10x- \frac{81}{\pi }=0

using a graph tool------> to resolve the second order equation

see the attached figure

the solution is the point

x=2.126 ft

therefore

<u>the answer is</u>

The uniform width around the circular pool border is 2.126 ft

Slav-nsk [51]

Answer:

  y = -1/6x +2

Step-by-step explanation:

The black vertical line in the middle of the graph is the y-axis. The blue line crosses it a the point marked 2. This is known as the y-intercept.

The slope of the line is the ratio of "rise" (vertical change) to "run" (horizontal change).

There is a marked point on the line at the y-intercept, where x=0 and y=2. There is another marked point to the right of that, where x=6 and y=1.

The vertical change between those two points is 1 -2 = -1.

The horizontal change between those two points is 6 -0 = 6

The slope is then -1/6.

__

The slope-intercept form of the equation of a line is often written as ...

   y = mx + b

where "m" is the slope (-1/6), and "b" is the y-intercept.

Using the values we found above, the equation of the line is ...

  y = -1/6x +2
