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:

  3

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.

Darius filled up his gas tank with 24 gallons of gas. For each mile that he drives, he uses 0.06 gallons of gas. How may gallons of gas are left in the tank after driving 240 miles?

Answers

Answer:

9.6 gallons

Step-by-step explanation:

Step one:

Given that the capacity of the gas tank is 24 gallons.

we know that 1 mile will consume 0.06 gallons

therefore x miles will consume 0.06x gallons.

the consumption for any distance is given as

0.06x gallons.

Step two:

if x=240 miles

then the gallons consume will be

0.06(240)=14.4 gallons

Step three:

the remaining gallons of gas in the tank will be

24-14.4=9.6 gallons

The reamining gallons will be 9.6 gallons

Please help me quickly! 3.5.2 Practice for income tax

Answers

Answer:

$15,475

Step-by-step explanation:

Mr. and Mrs. Jones make a combined $92,400 in taxable income. Looking at the table, their income is over $67,900 but not over $137,050.

So, the tax is $9,350. But, it also includes 25% of the amount over $67,900.

So,

$92,400 - $67,900 = $24,500

0.25 × $24,500 = $6,125

$9,350 + $6,125 = $15,475
