Answer from: originnjoku3632

2.0 x $10^{1}$

Step-by-step explanation:

1. length = 3.2 x $10^{5}$ m

width = 1.6 x $10^{4}$ m

Area of a rectangle = length x width

= (3.2 x $10^{5}$ ) x (1.6 x $10^{4}$ )

= 5.12 x $10^{9}$ $m^{2}$

2. length = 1.28 x $10^{7}$ m

width = 8 x $10^{3}$ m

Area of a rectangle = length x width

= (1.28 x $10^{7}$ ) x (8 x $10^{3}$ )

= 1.024 x $10^{11}$ $m^{2}$

$\frac{Area of rectangle 2}{Area of rectangle 1}$ = $\frac{1.024*10^{11} }{5.12*10^{9} }$

= 20

= 2.0 x $10^{1}$

Thus,

The area of rectangle 2 is 2.0 x $10^{1}$ times greater than the area of rectangle 1.

Answer from: Quest

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

step-by-step explanation:

Answer from: Quest

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
