164.38 = (1 x 100) + (6 x 10) + (4 x 1) + (3/10) + (8/100)
Answer:
The markup amount on the cost 39.99 $ will be: 8.78 $
Step-by-step explanation:
Given
- The cost = 39.99 (Let say in $)
As
22% = 0.22
The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22
so
Markup amount = 0.22 × 39.99
= 8.78 $
Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $
40^2 is how far apart the planes are after three hours travel
A = (h * b) / 2
A = 200
h = 4b
200 = (b(4b) / 2
200 * 2 = b * 4b
400 = 4b^2
400 / 4 = b^2
100 = b^2
sqrt 100 = b
10 = b ..... base is 10 cm
h = 4b
h = 4(10)
h = 40 <=== height is 40 cm
