Infinity many solutions because they both equal the same when the problem is solved.
Answer:
14.29%
Step-by-step explanation:
Let's do the count for Test #1:
2 + 5 + 6 + 1 = 14 total students
Out of which, below 70 is 2 people [only the leftmost bar]
Let's do the count for Test #2:
2 + 3 + 5 + 4 = 14 total students
Out of which, below 70 is again 2 people [only the leftmost bar]
So, to find percentage of people below 70, we divide the below 70 number of people with total number of people.
(2+2)/(14+14) = 4/28 = 14.29%
Answer: 504
Step-by-step explanation:
<span>In a complex fraction, either the numerator, or the denominator, or both, is a fraction.</span>
STU + STR = 180
8x + STR = 180 [ STU = 8x ]
STR = 180 - 8x
STR = SRT [ RS ≈ ST ]
Now, In ΔSRT,
we have, RST = 7x - 54, STR = SRT = 180-8x
Their sum is 180, as it constitutes a triangle.
7x-54 + 2(180-8x) = 180
7x - 54 + 360 - 16x = 180
306 - 9x = 180
9x = 306 - 180
9x = 306 - 180
x = 126/9
x = 14
So, option A is your answer.
Hope this helps!
