A pair of socks cost $18.50 the markup is 5% the taxes

I'm pretty sure the answer is 19.425

You have to round up or down because it is money.

The answer is $19.43

Step-by-step explanation:

I really hope this is correct.

$19.43

Step-by-step explanation:

At first you get 19.425

But money only has 2 decimal places and the 5 tells to to round the 2 up to 3

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
