Answer:
The first offer: 100.80 for 4kg
Step-by-step explanation:
To find the best offer, we just need to find the price per kilogram, and we do this by dividing the price by the number of kg:
100.80 for 4kg: 100.8/4 = 25.2 per kg
170.50 for 5kg: 170.5/5 = 34.1 per kg
260.60 for 6kg: 260.6/6 = 43.43 per kg
320.40 for 7kg: 320.4/7 = 45.77 per kg
The first offer has the smaller price per kg, so it is the best offer.
Answer:
After 13 minutes have past, there will be a volume of 18.762 L of punch.
Step-by-step explanation:
In this problem, we are asked to find the volume at 13 minutes. We are given this equation...
<em>y = -2.485x + 51.067</em>
We can use this equation to solve our problem. 13 represents our x-value so, we will plug 13 in for x in the equation above.
y = -2.485(13) + 51.067
Multiply -2.485 by 13.
y = -32.305 + 51.067
Now, add the numbers together.
y = 18.762
So, after 13 minutes have past, then the volume of the punch would be 18.762 L.
X^2-48 can be viewed as a difference of squares which would factor to:
(x+√48)(x-√48)
So b=√48
