Tristan took a math quiz last week. he got 26 out of 52 problems correct. what percentage did tristan get correct? write your answer using a percent sign (%).

50%

Step-by-step explanation:

To find the percentage of his correct answers, divide the amount of correct answers he got by the total number of problems.

26 out of 52 is another way to say

26/52

= 26 ÷ 52

= 0.50

0.5 is the decimal form of the answers Tristan got correct.

To convert it to a percentage, more the decimal two places to the right.

0.50 => 50%

Tristan got 50% of the problems correct.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
