<u>Find scale Factor:</u>

<u>
</u>

(\cfrac{length_1}{length_2})^3 = \cfrac{volume_1}{volume_2}


(\cfrac{length_1}{length_2})^3 = (\cfrac{125}{1000} )


\cfrac{length_1}{length_2} =  \sqrt[3]{\cfrac{125}{1000} }


\cfrac{length_1}{length_2} = \cfrac{5}{10} = \cfrac{1}{2}



<u>Find Surface area of the larger solid:
</u>

(\cfrac{length_1}{length_2} )^ 2=\cfrac{area_1}{area_2}


(\cfrac{1}{2} )^ 2=\cfrac{150}{area_2}


\cfrac{1}{4} =\cfrac{150}{area_2}


area_2 = 150 \times 4 = 600 \text{ cm}^2


Answer: 600 cm²

It would be 12 because if you divide 9 by 3/4 also known as .75 (by dividing 3 over 4) you get 9. In the picture is an example of what the dividend divisor and quotient are. Hope this helped! If not, you can ask me

The sum of a number and its reciprocal is 41/20. Find the number. smaller value larger value
Natali [406]

Step-by-step explanation:

Let the number is x. Its reciprocal will be 1/x. According to given condition, we get :

x+\dfrac{1}{x}=\dfrac{41}{20}\\\\\dfrac{x^2+1}{x}=\dfrac{41}{20}\\\\20x^2+20=41x\\\\20x^2-41x+20=0

It is a quadratic equation. The values of x are :

20x^2-25x - 16x+ 20 =0\\\\5x(4x - 5) -4( 4x - 5) = 0\\\\(5x-4)(4x-5)=0\\\\5x-4=0\ \text{and}\ (4x-5)=0\\\\x=\dfrac{4}{5}\ \text{and}\ x=\dfrac{5}{4}

The smaller number is 4/5 and the larger number is 5/4.
