Answer:

5.4

Step-by-step explanation:

First find the area of the square.

L times W

5 times 5=25

Now find the area of the cricle

A=\pir^{2}

Substitute pi with 3.14 and radius with 2.5

A= 3.14 times2.5^{2}

A=3.14 times 6.25

A=19.625

Now substract the area of the square from the area of the circle

Your answer will be 5.375

The rounded answer will be 5.4

Use the distributive property to solve the equation 2(m + 2) = 22. Describe what it means to distribute the 2 to each term insid
Mumz [18]

Answer:

m = 9  

It means that you are multiplying each of the values inside the parentheses by 2.

Step-by-step explanation:

2(m + 2) = 22

2m + 4 = 22

2m + 4 - 4 = 22 - 4

2m = 18                           -Divide both sides by 2

m = 9

The number of airline passengers in 1990 was 466 million. The number of passengers traveling by airplane each year has increased
taurus [48]

Answer:

2010.

Step-by-step explanation:

We have been given an exponential growth formula P(t)=466\cdot 1.035^t, which represents number of passengers traveling by airplane since 1990.

To find the year in which 900 million passengers will travel by airline, we will equate the given formula by 900 and solve for t as:

900=466\cdot 1.035^t

\frac{900}{466}=\frac{466\cdot 1.035^t}{466}1.9313304721030043=1.035^t

Take natural log of both sides:

\text{ln}(1.9313304721030043)=\text{ln}(1.035^t)

Using property \text{ln}(a^b)=b\cdot \text{ln}(a), we will get:

\text{ln}(1.9313304721030043)=t\cdot \text{ln}(1.035)

0.658209129198=t\cdot 0.034401426717

\frac{0.658209129198}{0.034401426717}=\frac{t\cdot 0.034401426717}{0.034401426717}

19.1331927775=t\\\\t=19.1331927775

This means that in the 20th year since 1990, 900 million passengers would travel by airline.

1990+20=2010

Therefore, 900 million passengers would travel by airline in 2010.
