On a model airplane, the scale is 5 centimeters=2 meters. if the model's wingspan is 28.5 centimeters, what is the actual wingspan

The actual wingspan is 11.4 meters .

Step-by-step explanation:

Given that the scale is 5 centimeters = 2 meters, then the following proportion must be satisfied:

5 cm / 28.5 cm  = 2 meters / x meters

x = 2*28.5/5

x = 11.4 meters

where x is the actual wingspan

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
