54% of 125 is what?
3. what percent of 200 is 104?
4. what percent of 124 is 62?

54% of 125 is 67.5

52% of 200 is 104

50% of 124 is 62

Step-by-step explanation:

Set up an equation:

Variable x = 54% of 125

54/100 = x/125

Cross multiply:

54 × 125 = 100 × x

6750 = 100x

Divide both sides by 100:

67.5 = x

Set up an equation:

Variable y = percent of 200 is 104

y/100 = 104/200

y × 200 = 100 × 104

200y = 10400

y = 52

Set up an equation:

Variable z = percent of 124 is 62

z/100 = 62/124

z × 124 = 100 × 62

124z = 6200

z = 50

what is the original number? you forgot to add it.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
