Answer:
w=p/2-t
Step-by-step explanation:
<span>3 4/9 + 5 1/3
= 3 4/9 + 5 3/9
= 8 7/9
11 1/5 + 2 1/2
= 11 2/10 + 2 5/10
= 13 7/10
7 4/5 + 1 9/10
= 7 8/10 + 1 9/10
= 8 17/10
= 9 7/10
10 3/4 + 15 1/3
= 10 9/12 + 15 4/12
= 25 13/12
= 26 1/12
7 1/2 + 6 1/3
= 7 3/6 + 6 2/6
= 13 5/6</span>
First convert the condors wingspan into inches
12x 9.5=114
convert hummingbird inches to decimal
2.5
subtract for difference
114-2.5=111.5
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
The answer is 75% because 150/200 converted to a percent is 75%
150/200= 0.75
0.75 x 100 = 75%
