GaryK [48]

Answer:

<h2>$110</h2>

Step-by-step explanation:

let us find 40% of $275

=40/100*275

Step two:

This means that the selling price is 275+110

I need help please
guajiro [1.7K]

Answer:

distance = 10.6

Step-by-step explanation:

A's coords are (5, 6)

D's coords are (-2, -2)

So the total horizontal distance between A and D is:

5 + 2 = 7

...and the total vertical distance is:

6 + 2 = 8

Now use Pythagorean Theorem:

7^2 + 8^2 = distance^2

distance^2 = 49 + 64 = 113

distance = squareroot of 113

distance = 10.6
