Answer:
23ft
Step-by-step explanation:
Area of the rectangle = LW
L is the length
W is the width
Given
Area = 414ft²
If the length of this garden is 5 feet longer than its width, then;
L = W+5
Substitute into the formula
414 = (W+5)W
414 = W²+5W
W²+5W-414 = 0
W = -5±√5²-4(-414)/2
W = -5±√25+1656/2
W = -5±√1681/2
W = -5+41/2
W = 36/2
W = 18ft
Since L = W+5
L = 18+5
L = 23ft
Hence the length of the rectangle is 23ft
So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.
3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.
3.54/3=1.18
10^7/10^8=1/10
Now we just multiply our answers together because we separated them before we divided.
1.18*1/10=.118
So the answer is .118 seconds
Answer:
V=(13/8)3ft3; SA=6⋅(13/8)2ft2
Step-by-step explanation:
25% of 28,000 is 7,000.
If the unit depreciated by 7,000, it is now worth 21,000.
