A senior class of 420 students will rent buses and vans for a class trip. Each bus can transport 50 students and 3 chaperones an
kykrilka [37]

Answer:

37 buses and 1 van.

Step-by-step explanation:

The cost to rent a van is $1200 for 50 students and 3 chaperones, while a bus for 10 students and a chaperone is $100 .

The cost of renting buses for 50 students is $500

What we do is rent 37 buses and 1 van

37 buses will take in 370 students with empty 2 spaces in 2 buses for chaperones since the chaperones are 36.

Then rent 1 van to take in 50 students and 1 chaperone.

The total cost here will be

$3700 + $1200 = $ 4900

This will help to safe cost.

BRAINLIESTTT ASAP! PLEASE HELP ME :)
sergiy2304 [10]

Answer:

\displaystyle Maximum: 11

Step-by-step explanation:

Convert this Quadratic Equation to Vertex Form by completing the square, \displaystyle y = a[x - h]^2 + k:

\displaystyle -5x^2 -10x + 6 \\ \\ -5x^2 - 10x + 25 + k \\ -5[x^2 + 2x - 5] + k \\ -5[x^2 + 2x + 1] + k → -5[x^2 + 2x + 1] + 11 → f(x) = -5[x + 1]^2 + 11 \\ \\ Vertex: [-1, 11]; 11 = Maximum

So as you can see, each time we broke the equation down, we used the formula \displaystyle [\frac{b}{2}]^2 to complete the square.

** In the Vertex Formula, −h gives the OPPOSITE terms of what they really are, so do not forget it.

I am joyous to assist you anytime.
