That would be 8. first parenthesis, then multiply, then subtract.
Answer:
11, 60.61
Step-by-step explanation:
this is the only set that fits a^2 +b^2=c^2
you square the first two numbers, add them together. Then you take the square root of that sum. This number must equal the third number for it to be a triple.
The answer would be about 89%
to solve this problem first you would have to subtract 4 from 36 to get 32 because you want to know how many she got right first .
so you put 32 over 36 ( the number she got right over the total number of questions ) and n ( the number you don't know yet ) over 100 . that will be the percent .
next all you have to do is cross multiply 32 times 100 and 36n , to get 3200 and 36n .
now you have to divide 3200=36n by 36 so you get n by its self but you have to divide on both sides of the equal sign .
when you divide you will then get 88 with a lot of remainder 8's so you would just round up to 89 .
finally you know n = 89% so she got 89% of her questions right .
Answer:
