Sheldon has a traditional health insurance plan. He has a $200 deductible. The level of co-insurance for his plan is 90/10, where 10 represents Sheldon’s portion. He does not have a co-payment. If Sheldon incurs a $1,500 hospital bill, how much money will the insurance company pay for the bill?

Answers

The answer is $1,170. The hospital bill is $1,500 less the $200 deductible which is $1,300. Sheldon will then pay for 10% of his portion so multiply $1,300 by 10% with is $130 and deduct it to $1,300 which gives you $1,170. 

The solution set for 12x2 − 13x + 3 = 0 is

Answers

The factor of the equation is (4x – 3) and (3x – 1). Then the solution of the equation will be 3/4 and 1/3.

What is a factorization?

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The equation is given below.

12x² − 13x + 3 = 0

Then the factor of the equation will be

     12x² − 9x – 4x + 3 = 0

3x(4x – 3) – 1 (4x – 3) = 0

           (4x – 3)(3x – 1) = 0

                                 x = 3/4, 1/3

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~

What wee need to do, is find what x equals...

12x^2 - 13x + 3 = 0

12x^2 - 13x = -3

12x^2 = 13x - 3

12x = 13 - 3

12x = 10

x = 0.75


Now we check...

12x^2 - 13x + 3 = 0

12(0.75)^2 - 13(0.75) + 3 = 0

12(0.5625) - 9.75 + 3 = 0

6.75 - 9.75 + 3 = 0

-3 + 3 = 0

0 = 0

If y varies inversely with x, and y = -16 when x = -64, what is the constant of variation?a. 16
b. 64
c. 100
d. 1,024

Answers

The constant of variation is 1024.

What is function?

The function is defined as mathematics expression defines a relationship between one variable and another variable.

Given, y varies inversely with x,

y ∝ (1/x)

y= k. (1/x)

Let's take the constant of variation as k

y = k. (1/x)

k = yx

Substitute the vaules of x and y,

k = (-16) x (-64)

k = 1024

Hence, the constant of variation is 1024.

Answer is (d).

Let's take the constant as K.

y=K. (1/x)
K = yx
K = (-16) x (-64)
K = 1024

On a trip, the fare was 75¢ for each adult and 50¢ for each child. If 20 passengers paid $12.00, how many adults and children went?Which of the following equations could not be used to solve the problem?
A) 75x+50(20-x)=1200
B) 75(20 - x) + 50x = 1200
C) 75x + 50x = 20(1200)

Answers

There are two cases in which this question can be answered. In our first case, let the number of adults be x and that of the children, 20 - x. On the second case, we let x be the number of children and 20 - x for adults. In the first case, the total fare may be expressed as 50x + 75 (20 - x) = 1200 and 75x + 50 (20 - x) = 1200. The expression in the first case is in letter b and the second case in letter a. Therefore, the answer for this item is letter c. 

Answer:

letter c
