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

In the diagram, there are 14 cubes glued together to form a solid. Each cube has a volume of 1/8in^3. Find the surface area of t
ElenaW [278]

Answer:

10\dfrac{1}{2}in^{2}

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 \dfrac{1}{8}in^{3}or can be converted to (\dfrac{1}{2}in)^{3}. So a single cube have edges that are \dfrac{1}{2}in.

The area of a single face of each cube is (\dfrac{1}{2}in)^{2}. We can also write this as \dfrac{1}{4}in^{2}.

Now that we have the area of a single face in the shape, we simply multiply the area by 42 faces.

Surface Area = \dfrac{1}{4}in^{2} x 42

Surface Area = 10\dfrac{1}{2}in^{2}

Work out the percentage change when a price of £50 is decreased to £40.
Ivanshal [37]
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
