 so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet the walkway is 10 feet wide so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together 
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared 

area of the walkway = 7850-5024 = 2826 feet squared 

hope helped

For an inscribed quadrilateral, opposite angles add up to 180 degrees. In this case, if we are looking for the measure of angle D, we can use the fact that angles I & D add up to 180 degrees. Since angle I = 117:
117 + D = 180
D = 63 degrees

Write the factored form of an equation that has the zeros 4 and -7.
sineoko [7]

The factored form of the equation that has the zeros 4 and -7 is y = ( x - 4)( x + 7 ).

<h3>What is the factored form of an equation that has the zeros or roots 4 and -7?</h3>

Roots are simply the points where the graph intercepts with the x-axis. ( y = 0 )
That is, y = 0 the roots

Given the roots of the equation;

  • 4
  • -7

Now, at x = 4,

x = 4

x - 4 = 0

y = ( x - 4)

Also, at x = -7,

x = -7

x - ( - 7 ) = 0

x + 7 = 0

y = ( x + 7 )

Hence; for the equation with the given roots; 4 and -7 will be;

y = ( x - 4)( x + 7 ).

The factored form of the equation that has the zeros 4 and -7 is y = ( x - 4)( x + 7 ).

A cell phone company offers a contract that costs $14.99 plus $0.06 per minute. Find the total number of minutes used if the bil
sattari [20]

Answer:

87 minutes

Step-by-step explanation:

Let the total number of minutes = m

Our equation is given as:

$20.21 = $14.99 + 0.06m

20.21 = 14.99 + 0.06m

Collect like terms

0.06m= 20.21 - 14.99

0.06m = 5.22

m = 5.22/0.06

m = 87

Therefore, the total number rod minutes used is 87 minutes
