I think we will need to use the 1mile=5280ft and the 1ft=30.48cm and the 1metre=100cm
so
3/4 mles=3/4 times 5280=3960ft
1ft=30.48cm
times both sides by 3960
3960ft=120700.8cm
1metre=100cm
1/100meter=1cm
times both sides by 120700.8
1207.008meter=120700.8cm=3/4mile
answer is 1207.008 meters
round
1207 meters
Hello,
x=3+2y
==> 3(3+2y)²-5(3+2y)y-16y=24
==>2y²+5y+3=0
==>(y=-3/2 and x= 0 or y=-1 and x=1)
sol={(0,-3/2),(1,-1)}
Answer:
Step-by-step explanation:
To obtain the strongest mix :
Maria:
2 cups of concentrate ; 5 cups of water
Ratio = 2/5 = 0.4 concentrate per 1 cup of water
Laurie:
3 cups of concentrate ; 7 cups of water
Ratio = 3/7 = 0.4285714 concentrate per 1 cup of water
0.4285714 > 0.4
Hence, Laurie's mix is the strongest as it has higher concentrate per cup of water.
The endpoints coordinates (b) should be (1,-3)
