at a simple annual interest rate of 4.5 percent, haw many years will it take Sam to earn 135 dollars on an original account of 1,000

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The simple interest formula is useful here:

I = Prt

where I is the interest earned on principal P invested at rate r for t years.

Filling in the given information, we can solve for the unknown.

135 = 1000·0.045·t

135/45 = t = 3

It will take 3 years for Sam to earn $135 on his account.

How many grams are in 1.204 x 10 24 atoms lithium

Answers

Answer:

We have:

1.204x10^24 atoms of lithium.

The weight of one atom of lithium is: 6.941 atomic mass units.

And we know that:

1 atomic mass unit = 1.661x10^(-24)g

Then the mass of one atom is 6.941 times 1.661x10^(-24)g

m = 6.941*1.661x10^(-24)g = 1.153x10^(-23)g

Then the mass of 1.204x10^24 atoms is 1.204x10^24 times 1.153x10^(-23)g

M = 1.204x10^24 *1.153x10^(-23)g = 1.388x10^(24 - 23) g

M = 1.388x10^1g = 13.88 g

Then 1.204x10^24 atoms of lithium wieght 13.88 grams.

The sum of two consecutive integers is 26. What are the integers? Question does not specify even or odd consecutive integers. Please HELP!

Answers

X is some integer

X+1 is the consecutive integer
Consecutive interferes are numbers like { 5,6,7 } or { 11,12,13 }. They are numbers that follow after one another

We sum x and x+1 getting 26 which means
x+(x+1)=26

2x+1=26

2x=26-1

2x=25

x=25/2

x=12.5

We made x an internet but 12.5 isn’t a integer so there are no solutions to the first integer equation.
So there are no consecutive integers that add up to 26.

If your teacher said consecutive even integers then your equation would be

x+(x+2)=26

2x+2=26

2x=24

x=24/2

x=12

And we can see that x=12 and x+2=12+2=14 add 12+14=26

Thar only applies if your teacher wrote consecutive even integers. With that even left out there are no solutions
