7/8 = 87.5%

I'm guessing it is meant to say round to the nearest 10th of a percent

If the question actually says something different comment so i can fix it

Original price = $20

Markup percentage = 65

Markup amount = 0

What is the profit?

65% of 20 = $12

Therefore Markup amount = $12

Profit = Original price + markup amount
= $20 + $12
= $32

If JM = 5x – 8 and LM = 2x – 6, which expression represents JL?

muminat

Answer:

The expression represents JL is 3x - 2.

Step-by-step explanation:

Given:

JM = 5x – 8 and LM = 2x – 6.

Now, to find expression represents JL.

JM = JL + LM

Subtracting both sides by LM we get:

JM - LM = JL.

JL = JM - LM

Now, putting the expression to get JL:

$JL=5x-8-(2x-6)$

$JL=5x-8-2x+6$

$JL=3x-2.$

Therefore, the expression represents JL is 3x - 2.

The equation cos−1 = x can be used to determine the measure of angle BAC.

Sergio [31]

we know that

in the right triangle ABC

the value of cosine of angle x is equal to

$cos(x)=\frac{AC}{AB}$

we have

$AC=3.4\ cm\\AB=10\ cm$

substitute the values

$cos(x)=\frac{3.4}{10}=0.34$

Find the measure of angle x

$x=cos(x)^{-1} =arc\ cos(0.34)=70.12\°$

Round to the nearest whole degree

$x=70\°$

therefore

the answer is

$70\°$
