Answer:
9x-7y+28=0
Step-by-step explanation:
using formula
y-y1=m(x-x1)
y-4=9/7(x-0)
7y-28=9x
9x-7y+28=0
<u><em>Answer:</em></u>
37/96
<u><em>Explanation</em></u>:
Hazel uses 1yd for 60 charms, so for 5/8yd she would use 5/8×60=37.5.
Because she can’t use a fraction of a charm, she would use 37 charms which is 37/96 of the charms she has.
The remaining side using cosine theorem is:
BC ^ 2 = 36 ^ 2 + 36 ^ 2 - 2 * 36 * 36 * cos (65)
BC = root (1496.573466)
BC = 38.68557181
Then, for the area we have:
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Substituting:
s = (36 + 36 + 38.68557181) / 2
s = 55.34278591
A = root (55.34278591 * (55.34278591-36) * (55.34278591-36) * (55.34278591-38.68557181))
A = 587.2874463
Rounding off we have:
A = 587.3
Answer:
A = 587.3
velocity of the boat = 36miles/3 hours
divide denominator and numerator by 6 respectively
6 miles/0.5hrs
thus, the we can say that the boat will travel 6 miles in 0.5 hour
