Answer:
The answer is A.
Explanation:
The perpendicular equation has a slope of the negative reciprocal. If we put the equation in slope-intercept form (y=mx+b), we can see the given equation's slope is 2/3. Therefore, the reciprocal must have a slope of -3/2 in slope intercept form (y= -3/2x+b).
Multiplying both sides of the equation by 2 to cancel the denominator, we have 2y = -3x +b. Then, move the -3 to the left side of the equation making the value positive, and we have 2y +3x = b. Therefore, A is the correct answer.
Answer:
The Jupiter ratio is 1: 5,719,360,000.
Explanation:
Since a basketball whose diameter is 25 centimeters represents the planet Jupiter, to find the scale (ratio) between Jupiter and the basketball, and then use this ratio to find the scaled diameter of the other planets, if Jupiter's diameter, 142,984 kilometers, is scaled to 25 centimeters, Saturn's diameter of 120,536 kilometers will be scaled to about 21 centimeters, the ratios are as follows:
1 centimeter = 0.00001 kilometers
25 = 0.000025
0.000025 = 142.984
1 = X
142.984 / 0.000025 = X
5,719,360,000 = X
Therefore, the Jupiter ratio is 1: 5,719,360,000.
