Answer:

Simplified from of given quotient is : \frac{1}{2}*10^{-4}

Step-by-step explanation:

We have given,

A quotient : \frac{4.5*10^{3} }{9*10^{7} }

We can simplify this quotient as:

\frac{4.5*10^{3} }{9*10^{7} }

or \frac{1*10^{3} }{2*10^{7} }

or \frac{1}{2}*10^{3-7}

or \frac{1}{2}*10^{-4}

This is the answer.

The expression 2( 21x + 75 ) represents the monthly tuition and the one-time materials fee that Jamie pays for his two children
ss7ja [257]

Answer:  x represents the number of months, 150 represents one-time materials fee,  2( 21x + 75 ) represents total fees in x months and 42 represents rate of change.

Step-by-step explanation:

Since, Here the expression 2( 21x + 75 ) represents the monthly tuition and the one-time materials fee that Jamie pays for his two children to join a science club.

Let, f(x) represents the monthly tuition fee

Therefore, f(x)= 2( 21x + 75 )

⇒f(x)= 42 x +150

Again according to the question, there is a one-time materials fee which must be free from the variable.

Therefore In f(x) , 150 must represent one time material fees.

And, x is variable, and here number of months is a variable.

Thus, x must be denote the number of months.

And, 42 must be denote the fees for 1 month.
