I Am Going Ask My teacher. I just screenshot it.
Find how many times 10 seconds is in 2 minutes and 45 seconds (16 times) and then multiply that my 6 (96) Then find what half of 6 is to compensate for the leftover 5 seconds (Half of 10 - so therefore the remaining amount of cars will be half of 6) to get 99 cars.
Answer:
26 students per classroom
Step-by-step explanation:
To solve this, the ratio 234 students:9 classrooms must be converted to:
s students:1 classroom
To convert the ratio, 9 was divided by 9 to get 1, and so you must also divide 234 by 9 to maintain the same ratio, which gives us the answer:
26 students: 1 classroom
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
