The percent increase from the original cost of the entertainment system to the cost of the entertainment system using the payment plan is 12%.
<u>Step-by-step explanation</u>:
- The original cost of entertainment system = $500
- The cost using payment plan= $125+ ($72.50
6)
- cost by payment plan ⇒ 125+ 435 = $560
Percentage increase = (higher value - lower value/ lower value) 100
⇒ ((560-500)/500) 100
⇒ (60/500) 100
⇒ 0.12 100
⇒ 12%
Answer:
x = 4
Step-by-step explanation:
By intersecting tangent and secant theorem:
The area of a shape is the amount of space it can occupy.
<em>The surface area of the larger prism is 4 times the surface area of the smaller prism. </em>
<em />
<em />
<em>Let the dimension of one side of the smaller prism be: l and w</em>
<em>Let the dimension of one side of the bigger prism be: L and W</em>
<em />
So, we have:
The area of these corresponding sides are:
---- the first
While, the area of the second is:
The ratio of these two sides are:
<em>This gives</em>
Cancel out common terms
Express as fractions
Also, we have:
This gives
Cross multiply
Hence, option (c) is true
