Element X decays radioactively with a half life of 9 minutes. If there are 760 grams of Element X, how long, to the nearest tent
ElenaW [278]

Answer:

Step-by-step explanation:

760·0.5^(t/9) = 19

0.5^(t/9) = 19/760

2^(-t/9) = 0.025

-t/9 = log₂(0.025)

t = -9log₂(0.025) = 47.9 minutes

In a triangle, the measure of one angle is five more than the first and the third angle is one more than four times the first.
katrin [286]

Answer:

A= 29

B=34

C=117

Step-by-step explanation:

<u>A triangle has three sides and a triangle always adds up to be 180</u>

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

<u>Now since you found A, find the other two by plugging A in!</u>

C = 4(29) + 1

C = 117

<u>Plug in the B equation</u>

B = 29 + 5

B=34

Check your answers

29 + 117 + 34 = 180

A patient's total surgery charges are $1,278. The patient must pay the annual deductible of $1,000, and the policy states a 80-2
musickatia [10]

Answer:

The patient owe $1255.6 .

Step-by-step explanation:

As given

A patient's total surgery charges are $1,278.

The patient must pay the annual deductible of $1,000.

The policy states a 80-20 coinsurance.  (i.e 20% of the surgery amount is given by the patient .)

20% is written in the decimal form .

= \frac{20}{100}

= 0.20

20% of patients surgery cost  =  0.20 ×  $1278

                                                 = $ 255.6

Patients owe = Deductible cost + 20% of patients surgery cost

                      = $1000 + $255.6

                      = $ 1255.6

Therefore the patient owe $1255.6 .
