With a certain medical insurance policy, the customer must first pay an annual $ 150 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 $620 and the second x-ray cost $930 . How much, in total, will he need to pay for these x-rays? He will be responsible for $ ???

$670

Step-by-step explanation:

The total cost of both x-rays are $1550.

$620 + $930 = $1550

He needs to pay a $150 deductible, leaving $1400.

$1550 - $150 = $1400

Since the company covers 70%, the person has to pay 30% of 1400.

30% = 0.3

$1400 × 0.3 = $520

The total cost of the 30% and the deductible is $670.

$150 + $520 = $670

step-by-step explanation

e2020 got it right

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
