What can you be more specific like a put it in a sentence. For example x*-260+7=?
Answer:
<em>4.52secs</em>
Step-by-step explanation:
Given the height of a falling object expressed as;
d=3t+5t^2
If the object travel 84 feet, we are to find the time t it takes to travel. On substituting;
84 = 3t+5t^2
3t+5t^2 - 84 = 0
t = -5±√25-4(3)(-84)/2(3)
t = -5±√25+1008/6
t = -5±32.14/6
t = -5+32.14/6
t = 27.14/6
<em>t = 4.52 secs</em>
<em>Hence it will take 4.52secs for the object to travel 84feet</em>
Answer:
2200 cubic feet of water
Step-by-step explanation:
25x22x4=2200
10% is 8, so multiply this by 7 to get 70%.
That would 56.
To get the 2% think of what 1% is then double it.
1% would be 0.8, so 2% would be 1.6
Then, to get the 0.5% just cut what 1% of it is.
Since 1% would be 0.8, you cut it in half to get 0.4.
Combine the 56, 1.6, and 0.4.
1.6+0.4=2.
So the problem would read 56+2=58.
58 is 72.5% of 80 games.
Step-by-step explanation:
you have to know how many inches make a foot or vice versa the you do simple proportion by equating the inches to the foot to get the answer. simple as abc
