Answer:
73.3
Step-by-step explanation:
50mi/h * 5280ft/mi * 1h/3600s = 220/3 = 73.3 ft/s
1. Maple and Oak (touch but without a right angle)
2. Maple and Birch (will never meet and are same distance from each other forever)
Answer:
c=45
Step-by-step explanation:
36^2+27^2=c2
1296+729=c2
2095=c2
Then square root it to get
c=45
Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28
you know that since the animals are healthy
chickens will have 2 legs and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56 -56
2y=8
y=4
</span>
