A scale model of the Eiffel Tower uses the scale shown. 2 centimeters represents 6 meters. The Eiffel Tower is 324 meters tall to the tip. What is the height of the model in centimeter?

108 centimeters

Step-by-step explanation:

Given that :

Scale model used for the Eiffel Tower :

2 centimeter represents 6 meters;

This means 2 centimeters on the model represents 6 meters of the Eiffel Tower.

To obtain the height of the model in centimeter :

Let the height of the model = h

h of model = actual height of tower

Actual Height of tower = 324 meters

Using cross multiplication :

2 = 6

h = 324

6 * h = 324 * 2

6h = 648

h = 648 / 6

h = 108

Hence, height of the model = 108 centimeters

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
