Answer:
r ≈ 19.0
s ≈ 17.7
Step-by-step explanation:
The relevant trig relations are ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
So, you have ...
cos(43°) = r/26
r = 26·cos(43°) ≈ 19.0
__
sin(43°) = s/26
s = 26·sin(43°) ≈ 17.7
Answer:
a:-2
Step-by-step explanation:
Answer:

Step-by-step explanation:
If we solve for the surface area for each of the 14 cubes, we will come up with a surface area larger than the shape. The best way to go around this is to solve for each face of the shape.
The shape has a total of 42 faces.
The volume of a cube is s³, each cube is
or can be converted to
. So a single cube have edges that are
.
The area of a single face of each cube is
. We can also write this as
.
Now that we have the area of a single face in the shape, we simply multiply the area by 42 faces.
Surface Area =
x 42
Surface Area = 
So the formula for price change is amount of change / original price * 100
50-40
= 10
10/50*100
= 1/5*100
= 20%
Hi there!
So all you need to do is replace the x in that equation with -1.
After you simplify the answer comes to 0, which leaves your correct
choice to be D. 0
Happy studying!
