neonofarm [45]

Given

Find out the  what was the insurance company's payment .  

To proof

As given

Sally Jones pays $50.00 a month for group health insurance

There is a $300 deductible

Her medical bills for the last year were $2,600.00

Linda's insurance company provided payment of 80% of the bills less the deductible.

Deductible

The  amount of money you will pay in an insurance claim before the insurance company starts paying you.

medical bill reducing the deductible = $2,600 -  $300

                                                             =  $2300

80 % is written in the decimal form

= \frac{80}{100}

= 0.8

than the equation becomes

Linda's insurance company provided payment  = 0.8× 2300

                                                                                = $1840

Therefore the the insurance company's payment be  $1840 .

Hence proved

A store manager determines that, on average, it takes Jemel 26.1 seconds to fold and put away 1 shirt. The manager uses a clock
Furkat [3]
<span>This problem is an example of ratio and proportion. A ratio is a comparison between two different things. You are given the time of about 26.1 seconds to fold 1 shirt. Also you are given 48 shirts. You are required to find the time in seconds to fold 48 shirts. The solution of this problem is,</span>  
<span>
26.1 seconds /1 shirt = time/ 48 shirts</span>
<span>time = (48 shirts) (26.1 seconds /1 shirt)</span>
<span>time<u> = 1,252.8 seconds</u></span>
<u>The time it takes to fold 48 shirts is 1,252.8 seconds.</u>

PLS HELP ME ASAP WITH 42!! (MUST SHOW WORK!!) + LOTS OF POINTS!! *best if show picture with work!!*
ddd [48]
I thought this would be simple, as I'm familiar with algebra and not really "The constant of proportionality," but I will do my best.

So this said "Constant of proportionality," is referring to basically the answers for the equation when X equals certain numbers.

Make a table of different answers when you plug in X and you get the 'Constant of proportionality.'

y = 2.5x + 3
y = 2.5(1) + 3
y = 2.5 + 3
y = 5.5

Since we plugged in 1 for X and got 5.5 for Y, our input and output is (1, 5.5)

Replace X for a different value, and you will get a bunch of different numbers that will in essence be your function inputs and outputs.  Make a table of these and you have your answer.

EXAMPLE - 
-= x =-   -= y =-
-= 1 =-   -= 5.5 =-
-= 2 =-   -= 8 =-
-= 3 =-   -= 11.5 =-
-= 4 =-   -= 13 =-


So there you have it.  I hope this helps!  If you have any further questions, don't hesitate to ask.
