Answer:

720 pennies

Step-by-step explanation:

Initially the Penny bank is 1/2 full

After removing 120 pennies it is 1/3 full;

Therefore. the fraction equivalent to 120 pennies is;

1/2 -1/3 = 1/6

Thus; Assuming the number of pennies that the penny bank can hold when full is x; then;

1/6 of x = 120

x = 120 × 6

   = 720 pennies

Hence, when the penny bank is full it can hold 720 pennies.

Answer:

720 pennies

Step-by-step explanation:

The difference between the  fraction originally contained  in the bank (1/2) and the fraction that remains  after Maria removes 120 pennies (1/3) represents the fraction occupied by the 120 pennies.

Therefore the fraction occupied by the 120 pennies= 1/2-1/3=1/6

thus if 1/6 of the bank can hold  120 pennies, then, when full it holds 120×6/1=720 pennies

This graph will start at (.5, 0) as the vertex.

To find this, all you need to do if find the point where inside the absolute value sign is equal to 0. Since the graph can never have a negative value, this will be the lowest point.

2x - 1 = 0

2x = 1

x = .5

From there, you can plot each point by going up two and to the left one.

Examples of Points: (1.5, 2) and (2.5, 4)

You can also plot the other side of the graph by going up two and to the right one.

These points can be found using the slope, which is the number attached to x (2).

Example of Points (-.5, 2) and (-1.5, 4).

For a certain map, the scale shows that 1 cm on the map equals 2.50 km on earth's surface. two towns on the map are 4.75 cm apar
Julli [10]
<span>In this problem, to find the answer we have to setup a series of ratios that relate the scale to real life distance. We know that 1cm = 2.50km, so that ratio would be 1cm/2.5km. For two towns that are 4.75cm apart on the map, we set a ration of 4.75cm/x km, where x is the actual distance. Now we set the ratios equal to each other and solve for x. 1/2.5=4.75/x where x = 4.75*2.5/1 = 11.875 and rounding up we get 11.88 km. The two towns are actually 11.88 km apart from each other.</span>
