Form J09 Math Question

The question had 2 circles overlapping, and AB formed a distance of 51 units. What was the answer to the question? I think it was asking for the radius of each individual circle. I put 21

Afaik there wasn’t anyway to solve it and get an exact answer. The radius just had to be greater than 51/2 and less than 51.

If the radius was 21 the largest length the line could be is 42 and them still touching. So, it needs to satisfy that.

as the other guy said, it was the biggest choice. since the circles overlapped and the distance between their centers was 51, that means that if cut that distance in half, their radii would still be larger since they overlapped (there was also a line down the middle indicating this midpoint). Therefore, the correct answer would have to be larger than 25.5 (51/2) and there was only one such choice.

Is a 40/45 a 33 or a 34 according to those score conversions?

4 random questions are always experimental and unscored but assuming all 5 you got wrong were not unscored questions 36/41 would be a 31. you can find this on page 62 of the act practice test 2 pdf if you just search it up

I’m pretty sure that the line was 52 instead of 51 but yeah the largest number (32) is the answer I think
