Answer:2

Step-by-step explanation:

Given

Physics problem requires 20 min

Math problem require 10 min

suppose x question of Physics and y questions of Math are done

so according to the question

x+y\geq 10\ldots 1

Time require for x Physics problem =20 x

Time require for y Math problem =10 y

so,

20 x+10 y\leq 120\ldots 2

On solving (1) and (2)

we get x=2 and y=8

Maximum no of Physics question which can be solved is 2

Use the commutative property of addition to simplify 12x - 36 - 6x.
nexus9112 [7]

12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)

<h2>Explanation:</h2>

The commutative property of addition states that:

a+b=b+a

So applying this property to our expression we have:

12x - 36 - 6x=-6x+12x-36 \\ \\ \\ So \ here: \\ \\ a=12x-36 \\ \\ b=-6x \\ \\ \\ Combining \ like \ terms: \\ \\ 12x - 36 - 6x=6x-36 \\ \\ \\ Common \ factor \ 6: \\ \\  12x - 36 - 6x=6(x-6) \\ \\ \\ Finally: \\ \\ 12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)

Amanda, Rafael, and Michael served a total of 92 orders Monday at the school cafeteria. Rafael served 2 times as many orders as
Schach [20]

The number of orders Michael, Rafael and Amanda served are 16.8, 33.6, and 41.6 servings

respectively.

<h3>Equation</h3>

  • Michael = x
  • Rafael = 2x
  • Amanda = 2x + 8
  • Total servings = 92 orders

x + 2x + (2x + 8) = 92

3x + 2x + 8 = 92

5x = 92 - 8

5x = 84

x = 84/5

x = 16.8 servings

Therefore,

Michael = x

= 16.8 servings

Rafael = 2x

= 2(16.8)

= 33.6 servings

Amanda = 2x + 8

= 33.6 + 8

= 41.6 servings

two pumps of different sizes, working together, can empty a fuel tank in 3 hours. the larger pump can empty the tank in 4 hours
bonufazy [111]
Suppose the larger pump alone can empty the tank in L hours, and the smaller pump can finish the job in S hours, then each hour the large pump empties 1/L portion of the tank, and the small pump empties 1/S per hour
Working together for three hours, they empty the whole tank, which is 100% of it, so 3/L+3/S=100%=1
Larger pump can empty the tank in 4 hours less than the smaller one, so L=S-4
replace L: 3/(S-4)+3/S=1
Make the denominator the same to solve for:
3S/[S(S-4)] +3(S-4)/[S(S-4)]=1
(3S+3S-12)/[S(S-4)]=1
(3S+3S-12)=[S(S-4)]
S^2-10s+12=0
use the quadratic formula to solve for S
S is about 8.6
The answer is not whole hour.
