Jack bought four dozen eggs at $10 per dozen six eggs were broken what percent of his money goes to waste?
Maurinko [17]
One dozen eggs is 48 eggs. Altogether that costs 40 dollars. If six of the eggs were broken then the money wasted would be 5 dollars.

The reason that it is 5 dollars is becuase it takes 10 to buy 12 eggs, and half of that is 6. So divide both 12 and 10 (separately) and you get 5 dollars for 6 eggs.

To get the percent you must divide 5 by 40.

The answer comes out to about 12.5% or 0.125.

So in the end, 12.5% of the money was wasted due to the broken eggs.

Hope this helped!

The dosage for a certain drug calls for 20mg per kg per day and is divided into two doses(1every 12 hours) if a person weighs 19
podryga [215]

Answer:

893.42

Step-by-step explanation:

1kg=2.205pounds

so 20mg is for 2.205pounds

therefore for 197pounds will be 1784.84mg

but the dose is once every 12hrs meaning twice a day so divide 1784.84/2 to get the pounds

A monument casts a 40 ft shadow. Adam is 6 ft tall and casts a 5 foot shadow. How tall is the monument
OLga [1]
The answer is 48 feet (D).

Explanation:

To solve this, you must think of the monument and its shadow and Adam and his shadow as a triangle, the person/object being the vertical leg, the shadows being the horizontal leg, and a line connecting them being the hypotenuse.  Also, we can assume that these triangles are similar.  First, we can set the scale to be 40/5 (the two shadows set a scale because the triangles are similar).  Then, we can put x/6 (the actual things are similar, and the scale was established to be building/measurement).  Next, we can set the two fractions equal to each other (40/5 = x/6) and solve.  We can cross multiply to get 5x = 40 * 6.  That goes to  5x = 240.  Finally, we can divide by five on each side to get x = 48 feet (D).
