Sammy buys his clothes at SuperDuper Discount Store. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. What is the total amount that he will have to pay? (Omit sales tax.)

Answers

you would have 10% chance

Step-by-step explanation:

I know, that's probably a lot to take in! :D

40 × 25% = 10

40 - 10 = 30

The final price of the shoes is $30.

100 × 30% = 30

100 - 30 = 70

The final price of the jacket is $70.

30 + 70 = 100

The total price of the items Sammy bought (no including sales tax) is $100.

What is the length of the hypotenuse of the triangle?

Answers

Step-by-step explanation:

Hey there!

Here;

ABC is a Right angled triangle.

Taking reference angle as angleA.

Now;

Hypotenuse (h) = AB

Perpendicular (BC)= 24 ft.

Base(AC)= 10 ft.

Now, Using Pythagoras relation;

[tex]h = \sqrt{ {p}^{2} + {b}^{2} } [/tex]

Put all values.

[tex]h = \sqrt{ {24}^{2} + {10}^{2} } [/tex]

Simplify it.

[tex]h = \sqrt{576 + 100} [/tex]

[tex]h = \sqrt{676} [/tex]

Therefore, h= 26ft.
