Mervin has some cartons of milk. He sold 2/5 of milk in the morning. He sold 3/4 of the remainder in the afternoon. 24 more cart
sergejj [24]

2/5 were sold in the morning. This is equal to 40% of the total.  That leaves 60% leftover.

 

3/4 were sold in the afternoon. This is equal to 75% of the 60% leftover or 45% of the total (.6x.75).

 

The difference between the two sales is 24 cartons or 5% (45%-40%). If 5% is equal to 24 then you can cross multiply to see what is the equivalent number of cartons out of 100%.

 

5/100 = 24/x

5x = 24(100)

5x = 2400

x = 480

 

ANSWER: 480 cartons

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I don't understand how to do this. :'(
natulia [17]

Answer:

Step-by-step explanation:

First and foremost, all quadratics have a domain of all real numbers (as long as we are not given only a portion of the graph, or one with endpoints. Our graph does not have endpoints, so it is assumed that the tails will continue to go down into negative infinity and at the same time, the x coordinates will keep growing as well.) Since our quadratic is upside down, it has a max. That means that none of the values on the graph will be above that point. All the values will be below that highest point (the highest y-value). Y-values indicate range, and since our highest y-value is at y = 2, then the range is

y ≤ 2

How do you determine if 5x-7y=14 is a function?
Pavlova-9 [17]
One way is to graph it and do the vertical line test
it is not a function if we can draw a vertical line in the graph that passes through 2 points of the graph

if we graph this function, we see there is no place we can draw a vertical line and hit the line twice

What is x2 + 2x + 9 = 0
vova2212 [387]

Answer:

x has no real solution

Step-by-step explanation:

Our equation is qudratic equation so the method we will follow to solve it is using the dicriminant :

  • Let Δ be the dicriminant
  • a=1
  • b=2
  • c=9
  • Δ= 2²-4*1*9 =4-36=-32
  • we notice that Δ≤0⇒x has no real solution
