Let,

Lee’s class size = L

Fred’s class size = F

 

We are told that Lee’s fifth-grade class has 1.0 times as many students as Fred’s

Therefore, L = 1F

L = F

 

Question A. If there are a total of 60 students, how many students does Fred’s class have? 

Total number of students = 60

L + F = 60

 

Since L = F

L + F = F + F + 60

F + F = 60

2F = 60

F = 60/2

F = 30

Therefore, if there are a total of 60 students, Fred’s class has 30 students.

 

 

QUESTION B. If there are a total of 60 students, how many students does Lee’s class have?

Total number of students = 60

L + F = 60

 

Since L = F

L + F = L + L + 60

L + L = 60

2L = 60

L = 60/2

L = 30

Therefore, if there are a total of 60 students, Lee’s class has 30 students.

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.
Virty [35]

Answer:

x=\frac{6e^3}{e^3-1}

Step-by-step explanation:

ln x - ln(x - 6) = 3

Apply natural log property

ln mn=ln m + ln(n), ln(m/n)=ln(m)-ln(n)

ln x - ln(x - 6) = 3

ln(\frac{x}{x-6} )=3

All natural log has base 'e'

\frac{x}{x-6} =e^3

cross multiply

x=e^3(x-6)

x=e^3x-6e^3

add 6e^3 on both sides and -x on both sides

6e^3=e^3x-x

6e^3=x(e^3-1)

Divide e^3-1 on both sides

x=\frac{6e^3}{e^3-1}

Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning.
lions [1.4K]

Answer:

Sometimes

Step-by-step explanation:

Example 1:

Take two numbers as 7,8

LCM of 7,8=7(8)=56

In this case, the lcm of two numbers is equal to the product of the two numbers.

Example 2:

Take two numbers as 6,3

6=3(2)

So,

LCM of 6,3=3(2)=6

In this case, the lcm of two numbers is not equal to the product of the two numbers.

Therefore,

Sometimes, the lcm of two numbers is equal to the product of the two numbers.

Raise 7 to the 9th power, then find the sum of the result and y
Dima020 [189]

The sum of 7 to the 9th power and y is expressed as 7⁹ + y

This statement will result in an exponential equation since we will have a base and an exponent

  • 7 raise to the 9th power is expressed as 7⁹

  • Taking the sum of the result and y;

  • The final expression will be  7⁹ + y

Hence the sum of 7 to the 9th power and y is expressed as 7⁹ + y

Express 9 m in terms of cm, μm, and nm. Use proper scientific notation in your answers.
devlian [24]

Answer:

9\times10^2cm

9\times10^6 \mu m

9\times10^9nm

Step-by-step explanation:

1 m = 100 cm

9 m = 100cm * 9 = 900 cm or 9\times10^2cm

1 m = 10^6 \mu m

9 m = 9\times10^6 \mu m

1 m = 10^9 nm

9 m = 9\times10^9 nm
