Choose the correct system of equations needed to solve this problem.

A
0.10d+0.05n=60.10d+0.05n=60.10d+0.05n=6

n+d=1.65n+d=1.65n+d=1.65

B
d=n+6d=n+6d=n+6

0.05n+0.10d=1.650.05n+0.10d=1.650.05n+0.10d=1.65

C
n=d+6n=d+6n=d+6

0.10d+0.05n=1.650.10d+0.05n=1.650.10d+0.05n=1.65

D
n=d+6n=d+6n=d+6

0.05n+0.10d=1.650.05n+0.10d=1.650.05n+0.10d=1.65

Answers

Answer:

C

Step-by-step explanation:

If you divide 1.65 by 6 you'll get 0.275 so then you'll add d+6n to get d+6 and then you'll solve the question for 6n and you'll get 1.65

16. A radioactive isotope has a half-life of 13 hours. Find the amount of the isotope left from a 400-milligram
sample after 65 hours. If necessary, round your answer to the nearest thousandth.
a. 25 mg
c. 0.049 mg
b. 7.692 mg
d. 12.5 mg
Please help. I only see answers for 52 hours

Answers

Answer:

Without the math: 65 hours is 5 half-lives

13 hrs = 1/2

26 hrs = 1/4

39 hrs = 1/8

65 hrs = 1/32

(1/2)^5 = 1/32

400 mg / 32 = 12.5 mg   that is, after 5 half-lives

with 98% confidence?

Answers

Answer:

Step-by-step explanation:

company wishes to estimate the mean monthly electric bill. If the standard

deviation is $400, how large a sample is required to estimate the mean electric bill to within $100

with 98% confidence?

Sample size, n = (Zcritical * σ) ÷ ME

σ = standard deviation ;

ME ≥ margin of error

α = 98% ; At 98% confidence level ;Zcritical = 2.326

n ≥ (2.326 * 400) / 100

n ≥ 930.4 / 100

n ≥ 9.304

n = 10

Emma noticed that the new admission fee for a zoo is 65% more than last year’s fee. If f represents last year’s fee, which of the following expressions represent the new admission fee? Select all that apply.

Answers

Answer: 1.65f

Step-by-step explanation:

Last year's admission fee = f

Percentage Increase in the admission fee = 65%

New admission fee will be the addition of last year's admission fee and the increase in the admission fee. This will be:

= f + (65% × f)

= f + (65/100 × f)

= f + (0.65 × f)

= f + 0.65f

= 1.65f

The new admission fee is 1.65f

John travels 16m ^2 +100 miles. /since he can only travel 8m +10 mph, it takes him 2m hours to make the trip. Solve for m

Answers

Answer:

m = 5

Step-by-step explanation:

distance traveled D= 16m^2+100 miles

speed, S= 8m+10 mph

time taken, T = 2m hours

We know that  D = S×T

⇒ 16m^2+100 = (8m+10)× 2m

⇒ 16m^2+100 = 16m^2+ 20m

⇒ 20m = 100

⇒ m = 5

Therefore, the value of m is 5
