Answer: 54
Explanation:
1 yard = 3 feet. 3 yards = 3 x 3 = 9 feet.
Area of the floor = 9 x 9 = 81 square feet
Total tiles required = <span>81÷1 1/2</span>
<span><span><span>81×<span>2/3</span>=<span>54</span></span></span></span>
Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.
14 you are adding 3 to each number
