Answer:
D
Step-by-step explanation:
Option D is the right choice.
Step-by-step explanation:
The current Social Security tax is 6.2%
Given maximum taxable earnings = $106800. This means the social security tax will be calculated on a maximum amount of $106800.
Social security tax on $23660 =
Social security tax on $89000 =
Social security tax on $106800 (maximum earnings) =
So, these values fall under option D. Hence, option D is the right choice.
B. x^2 - 4y^2 = 1
C. y = 3x - 3
D. y = 4x^5
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?
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
If you start with 1 cheerleader in row A, then you'll have 3 cheerleaders in row B (add on 2), and then 5 cheerleaders for row C (add on another 2), etc etc.
Note how: 1+3+5 = 4+5 = 9 which is a perfect square. Also note that 36 is a perfect square.
Rule: The sum of the first positive n odd numbers is going to be equal to n^2. In the example of adding the first three odd numbers (1,3,5), we have n^2 = 3^2 = 9 as the sum
So as you can see, we'll have n = 6 rows because n^2 = 6^2 = 36 and
1+3+5+7+9+11 = 36
which is the sum of the first six positive odd numbers. So we'll have 1 cheerleader in row A, 3 in row B, 5 in row C, 7 in row D, 9 in row E, 11 in row F to have 6 rows total.
To determine the number of rows in the triangular formation, set up an equation and solve for x. The number of rows is 6.
To determine the number of rows in the triangular formation, we can set up a series of equations.
Let x be the number of rows.
The first row will have 1 cheerleader, the second row will have 3 cheerleaders, the third row will have 5 cheerleaders, and so on.
We can set up the equation: 1 + 3 + 5 + ... + (2x-1) = 36.
This is the sum of an arithmetic sequence with a common difference of 2. Solving for x, we get x = 6.
Therefore, there will be 6 rows in the formation.

Answer:
After 4 months total cost of each health club would be the same that is $74.
Step-by-step explanation:
Let x represent number of months.
We have been given that Club A offers membership for a fee of $14 plus a monthly fee of $15.
The total cost of using Club A for x months would be .
We have been given that Club B offers membership for a fee of $18 plus a monthly fee of $14.
The total cost of using Club B for x months would be .
Let us equate both equations to find number of months, when both health clubs cost would be same.
Therefore, after 4 months the total cost of each health club would be the same.
The total cost of using Club A:
The total cost of using Club B:
Therefore, the total cost for each club would be $74.
