The mass of the radioactive sample at the beginning of the 8th day of the experiment a_13=310.7.

In a lab experiment, the decay of a radioactive isotope is being observed.

At the beginning of the first day of the experiment, the mass of the substance was 1300 grams and the mass decreased by 6% per day.

[tex]a_n=a_1r^{n-1}[/tex]

Use the given value in the formula so we get,

[tex]a_{13}=1100(0.9)^{13-1}[/tex]

Simplify the given term

[tex]a_{13}=310.7[/tex]

Therefore, The mass of the radioactive sample at the beginning of the 8th day of the experiment a_13=310.7.

Answer: [tex]\$0.15[/tex]

Step-by-step explanation:

Given

Six apples and one pear cost [tex]\$1.07[/tex]

Also, three apples and six pears costs [tex]\$1.47[/tex]

Suppose [tex]x[/tex] and [tex]y[/tex] be the price of apple and pear. So, we can write the cost as

[tex]\Rightarrow 6x+y=1.07\quad \ldots(i)\\\Rightarrow 3x+6y=1.47\quad \ldots(ii)\\\text{solve (i) and (ii) we get}[/tex]

Answer:

$11,113.20

$41,377.20

Step-by-step explanation:

The equation that would be used to represent the increase in rent every month is :

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

Rent paid in the first year = 9600

Rent paid in the second year = 9600 x (1.05) = 10,080

Rent paid in the third year = 9600 x (1.05)^2 = 10,584

Rent paid in the fourth year = 9600 x (1.05)^3 = 11,113.20

Rent paid in4 years is the sum of the rents paid each year :

9600 + 10,080 + 10,584 + 11,113.20 = $41,377.2

Answer:

The difference in amount = $430

Step-by-step explanation:

1- Annual contract:

The annual contract means a contract for 12 months. There is a month penalty for breaking the lease.  

This means that, if you left after 8 months, you will have to pay for 10 month.

Total paid = monthly payment * 10

Total paid = 535 * 10 = $5350

2- Month-to-month contract:

You will only paid for the 8 months you stayed,

Total paid = monthly payment * 8

Total paid = 615 * 8 = $4920

3- Getting the difference:

We can note that a month-month contract is a better option if you intend to stay for only 8 months

Difference = 5350 - 4920 = $430

Answer:

The width of the garden is 7 feet.

Step-by-step explanation:

If the area is 56 feet, and the length is 8 feet, we can put this into the area equation.

Area = width * length

A = wl

Substitute variables.

56 = 8w

Divide by 8.

7 = w, or w = 7.

The width of the garden is 7 feet.
