Answer:
The minimum number of Vinyl peel and stick floor tiles needed is 216 Tiles
Step-by-step explanation:
Here we have area size of Vinyl peel and stick floor tiles = 1 ft²
Size of floor of rectangular room = 12 ft × 14 ft = 168 ft²
Size of floor on rectangular hallway = 12 ft × 4 ft = 48 ft²
Total area of floor in rectangular room and rectangular hallway
= 168 ft² + 48 ft² = 216 ft²
Therefore number of Vinyl peel and stick floor tiles needed =
(Total area of floor in rectangular room and rectangular hallway)÷( Area size of Vinyl peel and stick floor tiles) = 216 ft²/(1 ft²) = 216
Therefore the minimum number of Vinyl peel and stick floor tiles needed = 216 Tiles.
Answer:
Number of tiles to tile the room: 168 tiles
Number of tiles to tile the hallway: 48 tiles
Total number of tiles: 216 tiles
Step-by-step explanation:
To find how many tiles Vinyl needs, we need to find the total area of the room and the hallway, and divide these areas by the area of each floor tile.
The area of a rectangle is calculated with the product between its dimensions (length and width).
Area of floor tile = 1 ft2
Area of rectangular room: 12 foot * 14 foot = 168 ft2
Area of rectangular hallway: 12 foot * 4 foot = 48 ft2
Number of tiles to tile the room: 168/1 = 168 tiles
Number of tiles to tile the hallway: 48/1 = 48 tiles
Total number of tiles: 168 + 48 = 216 tiles
45w + 150< 560
45w + 150> 560
150w + 45< 560
150w + 45 > 560
Answer: The answer is (B)
45w + 150> 560.
Step-by-step explanation: Given that 'w' represents the number of weeks s
Briyana saves money.
Since she can save $45 per week, so the amount of money she can save in 'w' weeks is $45w.
Also, she has $150 already with her, so the total amount of money saved is given by (45w + 150).
Now, since she needs to save at least $560, so we must have
45w + 150 > 560.
Thus, (B) is the correct option.

Answer: 0.79
Step-by-step explanation:
Given: The cost price of car = $19,000
The rate of depreciation = 21 % = 0.02
The exponential decay equation (depreciation) is given by :-
, where A is the initial amount and b is the decay factor for x years such that , where r is the rate of decay.
If we substitute the value of r , we get
The decay factor =
