The amount to be reduced is:  $40 -  $32.5 =  $7.5

The percentage decrease is: (7.5 : 40) * 100 = 18.25%

Answer:

answer is 18.76 percent.

Step-by-step explanation:

CP= $40

SP= $32.5

Markdown percent=?

now,

markdown %= CP-Sp/CP×100%

=7.5/40×100%

=750/40

=18.75%

Cuanto me da como resultado

Step-by-step explanation:

1) (-4)^2{\cdot}(-4)

We know that, a^x{\cdot}a^y=a^{x+y}

(-4)^2{\cdot}(-4)=(-4)^{2+1}\\\\=(-4)^3\\\\=64

2) (-2)^5{\cdot} (-2)^3

Again using above property,

(-2)^5{\cdot} (-2)^3=(-2)^8\\\\=256

3) 5^{-3}

We know that,

a^{-x}=\dfrac{1}{a^x}

So,

5^{-3}=\dfrac{1}{5^3}\\\\=\dfrac{1}{125}

4) 2.5^2=2.5\times 2.5\\\\=6.25

Hence, this is the required solution.

Use the diagram below to find the measured value of x.
dexar [7]

Answer:

They're the same angle. I would look up transversals so you could understand it a bit more. I'll upload a picture of a transversal in my answer but you should search it anyways.

Anyways,

To solve, you set 160 equal to the other side.

160 = 3x + 10

150 = 3x

x = 50
