Answer:
1/5
Step-by-step explanation:
divide any of the original dimensions by 5 and you'll get the dimensions of the scale drawing.
Answer:
w= -19/15 = -1.267
Step-by-step explanation:
-5(-3w - 8) = 21
(-5 * -3w ) + 40 = 21
15w +40 = 21
15w = 21-40
15w = -19
w = -19 /15 = -1.267
Answer:
3 tickets
Step-by-step explanation:
$23.55-$1.50= $22.05 / $7.35 = 3
I think you need to make it smaller amount like 2% is 5 so you can make it even more clearer.
Cos (a-b) = cos(a)cos(b) + sin(a)sin(b)
cos (a+b) = cos(a)cos(b) - sin(a)sin(b)
so, cos(a-b) - cos(a+b) =
=cos(a)cos(b) + sin(a)sin(b) - [cos(a)cos(b) - sin(a)sin(b)]
=2sin(a)sin(b)
