Answers
Answer:
D
Step-by-step explanation:
if y=2 then x=6, 2x3=6 ...if you multiple y with 3..you will get the answer of x
in that equation above..it will get x=3y...but there is no answer for it..so, you can convert it to, y=1/3x
Answer:
the answer is D

Answer:
Quadrant IV.
Step-by-step explanation:
Abscissa is the value of the x coordinate while ordinate is the y coordinate. In quadrant I, the ordered pair is (positive abscissa, positive ordinate.
Quadrant II has negative abscissa and positive ordinate.
Quadrant III is both negative abscissa and negative ordinate.
Lastly, Quadrant IV has positive abscissa and negative ordinate.

Step-by-step explanation:
The probability that the number is in set A’ is the probability that a number is not in set A.
From the venn diagram attached below, they are two sets, set A and set B. Set A has 3 elements {15, 12 18}, Set B has 5 elements {12 18 10 14 16}.
The total number of elements in the universal set is 10 i.e {10 11 12 13 14 15 16 17 18 19}
therefore the number of elements in set A' is 7, i.e {10 11 13 14 16 17 19}.
the probability that the number is in set A’ = number of elements in set A'/number of elements in the universal set
probability that the number is in set A’ = 7 / 10 = 0.7

b. what was the radius of the first ferris wheel?
c. The first ferri wheel took nine minutes to make a complete revolution. how fast was the wheel moving?
Answers
Answer:
a. The radius of the navy pier wheel is 56% of the radius of the first ferris wheel
b. The radius of the first ferris wheel was 179% of the radius of the navy pier ferris wheel
c. The wheel was moving at 0.70
Step-by-step explanation:
Navy pier wheel circumference = Cn
First ferris wheel circumference = Cf
Cn = 0.56*Cf
a.
Circumference Perimeter = 2*π*Radius
Navy pier wheel radius = Rn
First ferris wheel radius = Rf
Cn = 0.56*Cf
2*π*Rn = 0,56*2*π*Rf (equation 1)
dividing both sides by 2π
Rn = 0,56*Rf
b.
From equation 1
2*π*Rn = 0,56*2*π*Rf
dividing both sides by 2π
Rn = 0.56*Rf
dividing both sides by 0.56
Rf = *Rn
Rf = 1.79*Rn
c.
9 minutes / revolution
1 revolution = 2π radians
The wheel makes 2π radians in 9 minutes
Wheel velocity =
Wheel velocity = 0.70
