Answer:
28.27
Step-by-step explanation:
2*3.14*4.5=28.27
The constant proportionality is the proportionality of 59. Because it is the price, you just move the decimal point two places over to the left.
If you do this correctly you will get .59
Hundred thousand is the first 9, so we will round up to make 1 million.
Answer and explanation:
We know that this is in slope-intercept form. ( y = mx + b )
1/2 would be the slope (you would use this to graph the next point)
-4 would by your y-intercept (where the line crosses the x-axis)
With this information you could graph any point using the slope given, starting at -4 (x-axis) going down or up.
The miller needs 1-3/4 kg (or 1.75 kg) for two loaves.
Therefore the amount of flour needed for 1 loaf is
1.75/2 = 0.875 kg per loaf.
For 8 loaves, the amount of flour needed is
8*0.875 = 7 kg
Answer: 7 kg of flour is needed for 8 loaves.
