Find the area of a triangle with a height of 9 cm and a base of 5 cm

22.5 cm²

Step-by-step explanation:

Area of Triangle Formula: 1/2bh

Step 1: Define variables

h = 9

b = 5

Step 2: Plug into formula

1/2(9)(5)

1/2(45)

45/2

22.5 cm²

22.5 cm^2.

Step-by-step explanation:

Area = 1/2 * base * height

= 1/2 * 9 * 5

= 22.5 cm^2.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

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
