Write the Pythagorean theorem equation in an equivalent form with the a² isolated.

Answers

Answer:

[tex]a^{2}= -b^{2}+c^{2}[/tex]

Step-by-step explanation:

Rewrite the Pythagorean Theorem equation in terms of [tex]a^{2}[/tex].

[tex]a^{2}+b^{2}=c^{2}[/tex]

Subtract b squared from both sides.

            /       \

        4    ×        12

      /                   \

  2×2          ×         2×6

At the end of the season, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount. What is the sale price of the bat?

Answers

Discount=35%

35% of 347.250.35(347.25)121.54

Sale price

347.25-121.54$225.7

The sale price of the bat will be;

⇒ $225.71

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.

Now,

Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.

Hence, The discount price = 35% of $347.25

                                          = 35/100 × $347.25

                                          = $121.54

Thus, The sale price = $347.25 - $121.54

                                = $225.71
