Answer:
$3584
Step-by-step explanation:
- because its a rectangle, the area of the floor is length*width, so 16*14 = 224 square feet
- one square foot is $16, so 224 sqaure feet are 224*16
= 3584
Answer:
Area = 
Step-by-step explanation:
A=a+b
2h=13+13
2·12=156cm²
I hope this helps you :)
=> 4x = 16 - 8
=>4x= 8
=> x= 2
in short the answer is 2
X= -2 y=3, long explanation but thats the answer i got.
Answer:
a) 
b) t = 0.3 seconds
c) d = 4.9t²
d) d = 11 cm.
Step-by-step explanation:
One test involves catching a 1 m ruler and measuring the distance, d in meters, that the ruler will travel before being caught, the reaction time t in seconds is then calculated using the formula
.......... (1)
a) the simplified expression is
......... (2)
b) If d = 44 cm = 0.44 meters, from equation (2) we get,
t = 0.299 seconds ≈ 0.3 seconds (Approximate)
c) If we make d as the subject of the equation, then

⇒ d = 4.9t² .......... (3)
d) Now, if
seconds, then from equation (3) we get,
d = 4.9 (0.15)² = 0.11 meters = 11 cm (Answer)
