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 mass was decreasing by 6% per day. Determine the mass of the radioactive sample at the beginning of the 8th day of the experiment. Round to the nearest tenth (if necessary).
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.

18. Miguel paid $9600 rent for his apartment the first year. Every year for
the next 3 years the rent increased 5%.
a. How much rent did he pay in the fourth year?
b. How much rent did he pay altogether in the 4 years?
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

Jacob has a rectangular garden with an area of 56 square feet.The length of the garden is 8 feet.What is the width if the garden?
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.

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]
[tex]x=0.15,\ y=0.17[/tex]
The cost of an apple is [tex]\$0.15[/tex]
