Answer:
C. 74 sqft
Step-by-step explanation:
The bottom has a surface area of 4ft * 5ft = 20sqft
Theres two 3ft x 5ft sides and two 3ft x 4ft ones.
2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft
Total surface of the outside is thus
20sqft + 54sqft = 74sqft
Answer:
<h3>Car A</h3>
- Initial price = $30000
- Initial depreciation = 20%
- Further yearly depreciation = $2000
<u>The equation to reflect the above:</u>
- A(t) = 30000 - 0.2*30000 - 2000t ⇒
- A(t) = 24000 - 2000t
<h3>Car B</h3>
- Initial price = $25000
- Initial depreciation = 10%
- Further yearly depreciation = $1500
<u>The equation to reflect the above:</u>
- B(t) = 25000 - 0.1*25000 - 1500t ⇒
- B(t) = 22500 - 1500t
Answer:
A
Step-by-step explanation:
← divide numerator/ denominator by 4
= 
Thus A form a proportion
≠ 
Thus B is not a proportion
← divide numerator/ denominator by 4
= 
≠
Thus C is not a proportion
≠
Thus D is not a proportion
