Answer:
Step-by-step explanation:
Let x = the number of 50-cent increases in the cost of a book rental.
Right now he is renting 38 books per day at $3 per rental. If he raises his price he will lose 4 rentals per increase. The money part of this is:
$3 + .5x = the price per book rental after the increase. That's how much money he will make. The money made is NOT the same thing as the number of rentals. Therefore, they are put into separate expressions.
The number of rentals is:
38 - 4x. This is the number of books he is currently renting minus the number of book rentals he will lose per price increase. Putting those 2 expressions together and multiplying them will give you the end result of this increase in price.
(3 + .5x)(38 - 4x) = 114 - 12x + 19x - 2x², or putting it in descending powers of x and combining like terms:
-2x² + 7x + 114
The answer is going to be 4.5

Answer:
Pour 7 times
Step-by-step explanation:
In order to get 3 equal volumes when starting with a 9L jug, each volume must be 3L.
1) Pour from the 9L into the 5L
2) Pour from the 5L into the 2L (resulting in 3L leftover in the 5L jug)
Now we have 1 jug of 3L
3) Pour the 3L from the 5L jug into the 4L jug (to get it out of the way)
4) Pour the water from the 2L back into the 9L jug (which is now 6L fill)
5) Pour water from the 9L jug into the 5L jug
6) Pour from the 5L jug into the 2L jug resulting in 3L leftover in the 5L jug
Now we have 2 jugs of 3L
7) Pour water from the 2L jug into the 9L jug which has 1 L of water in it.
Congratulations you now have 3 jugs, 3L each.
Answer:
First of all draw a base line
then, get a compass and extend it as needed for the base of triangle
after that, adjust the length of compass to 2 cm approximately
then at both end points of base draw angle of 60° to 75° ( because you asked for a larger triangle )
then draw out a straight line from the angle you made and intersect both of the lines then you get the third point.
Now, boom your triangle is ready..
