With a certain medical insurance​ policy, the customer must first pay an annual ​$250​deductible, and then the policy covers 70​% of the cost of​ x-rays. The first insurance claims for a specific year submitted by a person are for two​ x-rays. The first​ x-ray cost ​$700​, and the second​ x-ray cost ​$950. How​ much, in​ total, will he need to pay for these​ x-rays? I got $345, but it's wrong.

$495 (745 if you include the $250 deductible)

Step-by-step explanation:

70% of 700 is 490

700 - 490 = 210

70% of 950 is 665

950 - 665 = 285

210 + 285 = $495

495

Step-by-step explanation:

70% of 700 is 490

700 - 490 = 210

70% of 950 is 665

950 - 665 = 285

Add them together

210 + 285 = 495

The reason you might have gotten 345 is because you subtracted 495 with 250 but 250 is how much he has to pay for the medical insurance, not how much he also get off

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
