Answer:

(©) 1.05 x 10^5

Step-by-step explanation:

105,000.

Scientific notation is of the for a * 10^b

where a is a number between 1 and less than 10

move the decimal to make a be correct

1.05000

we moved it 5 places to the left, so b is 5

It is positive since we moved it to the left

1.05*10^5

We drop the zeros to the right of the 5

Enter the value of a and b that complete the sum: 3/x + 5/x^2 = ax+b/x^2

Aleksandr [31]

Answer:

a= $\frac{3}{x^{2} }$

b=5

Step-by-step explanation:

we are given

$\frac{3}{x} }$ + $\frac{5}{x^{2} }$ =ax+ $\frac{b}{x^{2} }$

we will compare both sides of equaion

$\frac{b}{x^{2} }$ = $\frac{5}{x^{2} }$

comparing both sides we get

b=5

and

$\frac{3}{x} }$ =ax

a= $\frac{3}{x^{2} }$

hence

a= $\frac{3}{x^{2} }$

and b=5

Step-by-step explanation:

Let Theo's siste can paint a fence in x times

Given.

Theo can paint a fence three times as fast as his sister can. Working together, they can paint a fence in 9 hours.

$\frac{1}{x}+\frac{1}{3x} =\frac{1}{9}\\\frac{3+1}{3x} =\frac{1}{9} \\\frac{4}{3x}=\frac{1}{9}$

Apply cross multiplication

$x=\frac{9\times 4}{3}\\x=\frac{36}{3} \\x=12hours$

Theo’s sister to paint the fence in 12 hours.
