A dinosaur fossil is 93,550,000 years old. How can you express this age in scientific notation
garik1379 [7]

1. 9.355 × 10^{7} can be used to express the age of the dinosaur fossil.

Step-by-step explanation:

Step 1; To determine which value is the closest to 93,550,000 we must calculate how much the 4 options equal. If there are decimals in the number, they are moved from the decimal part of the number to the integer part with every power of 10 i.e. 2.4 × 10 = 24, 2.44 × 10² = 244.

Step 2; Now we determine how much the 4 options equal.

1. 9.355 × 10^{7} = 93,550,000.

2. 9 × 10^{7} = 90,000,000.

3. 9.36 × 10^{7} = 93,600,000.

4. 9.3 × 10^{7} = 93,000,000.

Out of the four options, option 1 equals the value of 93,550,000. So option 1 can be used to express the age with the highest precision.

Ian has the option of purchasing or renting a home. The purchase option requires a loan of $100,000 for a 20-year term at a 4.9%
jenyasd209 [6]

Answer:

The correct answer to the following question will be "70.56".

Step-by-step explanation:

The given values are:

Loan requires, PV = $100,000

Years = 20

Number of months, n = 240

Rate interest = 4.90000%

Monthly rate, r = 0.408333%

Monthly rental payment = $725

As we know,

PV=PMT\times (\frac{1}{r})\times [1-[\frac{1}{(1+r)^n}]]

On putting the values in the above formula, we get

⇒  100000=PMT\times (\frac{1}{0.004083333})\times [1-(\frac{1}{(1+0.004083333^{240})})]

⇒  100000=PMT\times 152.8014557

⇒  PMT=\frac{100000}{152.8014557}

⇒  PMT=654.44

Now,

Saving \ Per \ Month =Rent \ per \ month-PMT

On putting the values, we get

⇒                             =725-654.44

⇒                             =70.56
