Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140
<span>5x^2 + 5y^2 + 10x − y = 0 it is the same of </span>
<span>x^2 + y^2 + 2x −1/5y = 0
and then </span>
(x + 1)^2 - 1+ (<span><span>y−1/10)^2 -1/100=0
</span> </span>(x + 1)^2 + (<span>y −1/10)^2 =(101/100)
the center is C(-1, 1/10), and the radius is R= sqrt(101)/10
</span>
Answer:
$30,600
Step-by-step explanation:
1 hectare = 10,000 
0.36 hectare = 0.36 * 10000 = 3600
She pays $8.50 per square meter. Thus, the total cost is:
Answer: $30,600
0.5 cups of cheese
Amy: 1.6 divided by 8 = 0.2 cups of cheese per serving
Sarah: 2.5 divided by 10 = 0.25 cups of cheese per serving
0.25 - 0.2 = 0.5
