4.67 as a fraction equals 467/100
The answer is 3.33%. Anna reduced her CO2 emissions by 3.33% from using 600 gallons of gas annually than from using 900 gallons of gasoline annually. I arrived to this answer through multiplying gallons by 20 pounds of C02 (600*20) = 12000; (900*20) = 18000. Then I proceeded to subtract 12000 from 18000 which yielded me 600 (18000-12000 = 600). Lastly, I divided 600 by 18000 and it gave an answer of .0333. Then, I converted it to percent, thus, yielding me the answer of 3.33%.
Answer:
Image point → (-4, 0)
Step-by-step explanation:
Coordinate of a point → (0, 1)
Rule for the transformation has been given as,
D₄ o R₉₀
First use R₉₀ → Rotation of the point by 90° counterclockwise
Rule for the rotation of a point (x, y) by 90° counterclockwise about the origin,
(x, y) → (-y, x)
(0, 1) → (-1, 0)
Further use D₄ → Dilation of the point by a scale factor of 4 about the origin
If a point (x, y) is dilated by a scale factor 'k' about the origin rule for the dilation is,
(x, y) → (kx, ky)
By applying this rule,
(-1, 0) → (-4, 0)
Therefore, image point will be → (-4, 0)
Answer:
2 : 5
Step-by-step explanation:
In order to obtain the ratio between numbers, we divide by the largest common factor between both.
In this question, the numbers are;
36 : 90
The largest common faction is 18. Dividing both numbers by 18, we have;
36 / 18 : 90 / 18
2 : 5
The ratio is; 2 : 5
