Answer:
60%
Step-by-step explanation:
To find the total pass = 65 * number of student that passed, let it be be represented by P and number of students that failed F
Total pass = 65p
And total fail = 35F
For the total pass and failure will be 53(P+F)
Equating to total pass and total fail
65P +35F = 53( P+ F)
65P+35F = 53P+ 53F
65P-53P =53F-35F
12P=18F
2P= 3F
Hence there are 3 passing scores for every 2 failure scores, hence there are a multiple of 5 scores and the same multiple of 3 passing scores.
3/5 * 100= 60%
Answer:
3x+(4x-1)+90°=180°{sum of angles in a triangle}
3x+4x-1+90°=180°
7x+89°=180°
7x=180°-89°
7x=91°
divide both sides by 7
x=13
0.00305 and 8920000...if the exponents are negative 3 and 6
