Answer:
-60% decrease
Step-by-step explanation:
60 is the old value and 24 is the new value.
percent change = 
x 100%
so for this problem, you can substitute the values given in the formula:
percent change = 
x 100% = 
x 100% =
-60% (decrease)
2,830 x 3 =G three times 0 is 0
2,830 3 times 3 is 9
x 3 3 times 8 is 24 carry the two
8,490 3 times 2 is 6 plus the carried 2 is 8
Answer:
find b: since the triangle is right angle triangle apply the Pythagorean theorem
c²+b²=d²
b²=d²-c²
b²=16²-12²
b²=256-144
b²=112
<h2>b=√112 = 4√7</h2>
the sum of the angle of the triangle=180
( in top Δ abd ) sin Ф=opp/hyp
sinФ=b/d=4√7/16= √7/4 radian
convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees
<h2>which makes A= 38 degrees ( adjacent angles are equal when they have common side and do not overlap)</h2>
find a=?? apply law of cosine
a²= d^2 + c^2 − 2dc cosA
a²=16² + 12²-2(16)(12)cos38
a =√(16² + 12²-2(16)(12)cos38)
<h2>a=9.87 rounded to the nearest hundredth</h2>
(i hope it is right )
