Answer:
a/b = 12
Step-by-step explanation:
2a -5b 1
------------- = -----
3a+2b 2
We can use cross products to get in the form of a /b
2(2a-5b) = 1(3a+2b)
Distribute
4a -10b=3a+2b
Get the a terms on the left and the b terms on the right
Subtract 3a from each side
4a-3a -10b=3a-3a+2b
a - 10b = 2b
Add 10b to each side
a-10b +10b = 2b+10b
a = 12 b
Divide each side by b
a/b = 12b/b
a/b = 12
arc length = pi /180 * angle in degree * radius
2 = pi/180 * 30 *r
2 = pi/6 *r
multiply by 6/pi
12/pi =r
3.819718634 =r
Answer: r =3.82 inches
<span>Similar means their sides have the same ratio but don't have to be the same length. So if two rectangles are similar with a scale factor of 2 then the ratio of their areas would be 4:1.
Hope this helped :)</span>
I think it’s D I don’t know
26/52 because reducing like terms gives us half compared to 21/49 being way less than half based on adding the numerators of these 2 fractions.
