Answer:
10.26 dollars.
Step-by-step explanation:
just multiply 3.8 by 2.7
Answer:
Step-by-step explanation:

V30% mixture + v100% mixture = v60% mixture
0.3(10-x) + x = 0.6(10)
3 - 0.3x + x = 6
0.7x = 6 - 3
0.7x = 3
x = 3/0.7
x = 4.286 quarts

Please review the attached graph for a visual of these key features.
A whole hour or revolution is 60 minutes and 360° so the area of a sector is:
A/πr^2=α/360
A=απr^2/360...now we need to find the angle α/360=5/60, α=30° so:
A=30πr^2/360
A=πr^2/12 and r=11.25ft so
A=11.25^2*π/12
A≈33.13 ft^2
