622
rounded to nearest tens = 620
rounded to nearest hundreds = 600
Since the temperature starts at 40 degrees F at sunrise and increases 4 degrees every hour afterward, we can begin our equation.
If you visualize the graph, the y-axis (left side) will denote the degrees and increase slightly every hour. The x-axis (at bottom) will show the hours as they pass by. In slope-intercept form, the b must be 40 degrees, since this is where we start, and the slope m must be 4, since this is the amount the temperature is changing every hour.
Therefore y=4x+40
This equation will tell you the temperature (y) at any hour (x).
We know that
<span>Total soil--------> 3/4 ton
</span><span>divide it by 8
(3/4)/8----> 3/(4*8)----> 3/32 ton----> 0.09375 ton----> multiply by 1000---> 93.75 kg
the answer is
</span>93.75 kg f<span>or each bed</span>
To answer this problem you have to use a ratio, if it begins with 8:500, multiply 40 or 20,000/500 on both sides to get 320:20,000
T=1.66/2 or it can be t=1 2/3 ÷ 2
