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:
The total cost of the cylindrical tank is $226.28
Step-by-step explanation:
Dimensions of the tank are: radius = 3 ft , height = 2 ft
Cost per cubic foot = $4
Now, total volume of the cylindrical tank = 
Here, take π = 22/7
So, Volume = 
So, the <u>volume of the tank = 56.57 cubic feet. </u>
Now, cost per cubic foot = $4
Hence, the total cost of the tank = Total Volume of the tank x cost per foot
= 56.57 x 4 = $226.28
So, the total cost of the cylindrical tank is $226.28
Answer:
x(t) = -1 + 4t
y (t) = 3 - 5t
Step-by-step explanation:
The end points of the line segment are (-1, 3) and (3, -2).
Let a = (-1,3) and b = (3,-2)
Now, find the value of (b-a)
(b-a) = ((3+1), (-2-3))
b-a = (4, -5)
Therefore, the parametrization of the given line segment is
r(t) = a + (b-a)t
r(t) = (-1,3) +(4,-5)t
r(t) = (-1+4t, 3-5t)
We can rewrite this as
x(t) = -1 + 4t
y (t) = 3 - 5t
Answer:
A
Step-by-step explanation:
Plug in the values of each of the coordinate pairs into the linear system.
2x - 8y = 0, -3x - 8y = 20
A)
2*-4 - 8*-1 = 0
- 8 - (-8) = 0 -> CORRECT!
-3x - 8y = 20
-3*-4 - 8*-1 = 20
12 - (-8) = 20 -> CORRECT!
You don't need to try any other pairs, you already know that this is the solution to the problem! Remember, in the future, just plug all the coordinate pairs into the equation. Whichever one makes the equation true is the correct solution! Hope this helps!
