Answer:
Circ = 2 x pi x r
28.3 = 2 x 3.14 x r
r = 28.3 / (2 x 3.14) = 4.51 cm
r = 4.5 cm

y=5x+6 this lines slope= -5
-3 (6x-y)= -54
6x-y= 18
y= 6x-18 this lines slope= -6
parallel lines slopes equal
-5 is not equal -6 not parallel
Answer:
W= 875+35h
Step-by-step explanation:
W= the amount of water in the pool
h= # of hours
The pool already had 875 gallons of water, so you need to add 35 times the number of hours to find the total amount of water in the pool after filling it.
Step-by-step explanation:
Given Ben's observations when the wait time is as advertised represented by the equation 2|x − 2| − 12 = 0, to get the times when the serving time is as advertised, relative to noon, we will calculate for the value of x in the equation;
Note that the modulus of the function |x-2| will return both positive and negative value.
For the positive value of |x-2|;
2|x − 2| − 12 = 0
2(x − 2) − 12 = 0
open the parenthesis
2x-4 - 12 = 0
2x - 16 = 0
add 16 to both sides
2x-16+16 = 0+16
2x = 16
x = 16/2
x = 8
For the negative value of |x-2|;
2|x − 2| − 12 = 0
-2(x − 2) − 12 = 0
open the parenthesis
-2x+4 - 12 = 0
-2x - 8 = 0
add 8 to both sides
-2x-8+8 = 0+8
-2x = 8
x = -8/2
x = -4
Hence the times when the serving time is as advertised, relative to noon are 8minutes and 4minutes
