9. B
For number 6, 10 vans times 12 students is 120 students. 432 - 120 = 312. 312 students divided by 6 buses is 52. To check if it right I tried Middle School B. 5 vans times 12 students is 60. 164 students - 60 = 104. 104 divided by 2 buses equals 52. So 12 students is the right answer.
For number 9, 35*2=70 and 15*5=75. 70+75=145.
Answer:
square root of 3 is 1.7 so put it closer to 2
square root of 8 is 2.8 so put it closer to 3
square root of 23 is 4.7 so put it closer to 5
Step-by-step explanation:
Consider 8 thousandths + 6 ones 8 thousandths
We have to determine the number of thousandths in the given number sentence.
8 thousandths = 0.008
6 ones 8 thousandths = 6.008
8 thousandths + 6 ones 8 thousandths = 0.008 + 6.008
= 6.016
So, the sum is 6.016
Therefore, there are 6 thousandths in the sum of the given numbers.
-2x^2 + 3x - 9 = 0
The quadratic is not factorable so quadratic formula must be used.
x = (-b + - √(b^2 - 4ac))/2a
a = -2, b = 3, c = -9
x = (-3 + - √(9 - 4*-2*-9))/-4
x = (-3 + - √(-63))/-4
x = -3 + - 3i√7
--------------
-4
x = 3 + 3i√7 x = 3 - 3i√7
------------ ------------
4 4
