A publisher sells 10⁶ copies of a new book. Each book sells 10² pages. How many pages total are there in all of the books sold?
KatRina [158]

Answer:

10^12.

Step-by-step explanation:

You need to solve 10^6 * 10^2 without using standard notation. As with variables, if you had x^6 * x^2 you would add the exponents. Replace x with 10. Your answer is 10^8. As a sidenote, only multiply exponents when raising a power to another power, e.g. (10^6)^2 = 10^12.

Molly Invests $8,600 into her son's college fund, which earns 3% annual interest
8_murik_8 [283]

Answer:

n= 13.8 years

Step-by-step explanation:

<u>First, we need to determine the daily interest rate:</u>

Daily interest rate= 0.03 / 365

Daily interest rate= 0.000082

<u>Now, using the following formula we can determine the number of days and years:</u>

n= ln(FV/PV) / ln(1+i)  

n= ln(13,000 / 8,600) / ln(1.000082)

n= 5,039 days

<u>In years:</u>

n= 5,039/365

n= 13.8 years

Willis tower in Chicago is 1450 feet tall. The John Hancock Center in Chicago is 1127 feet tall. Suppose you are asked to build
gayaneshka [121]

Answer:

Small Scale replica of John Hancock tower is approximately 2.33 m.

Step-by-step explanation:

Given:

Height of Willis tower = 1450 ft

Height of John Hancock Center = 1127 ft

Small Scale replica of Willis tower = 3 m

We need to find Small Scale replica of John Hancock tower.

First we will find the per meter scale of Willis tower and then using the same we will use to find the Small Scale replica height of John Hancock tower.

For 3 meter scaling = 1450 ft

So for 1 meter scaling = Number of foots in 1 meter Scaling

By Using Unitary method we get;

Number of foots in 1 meter Scaling = \frac{1450}{3} = 483.333 \ ft

Now we had 1 meter scaling as 483.333 ft and we need to find meter scaling for 1127.

So again Using Unitary method we get;

Small Scale replica of John Hancock = \frac{1127}{483.333} = 2.331 \ m

Rounding to nearest hundred we get;

Small Scale replica of John Hancock tower is approximately 2.33 m.
