2. Lamar purchases comic books at garage

Otrada [13]

Answer:

Lamar will charge $\$7$ to the comic dealer for a comic book.

Solution:

It is given that lamar purchases a comic book for $\$4$ . He then marks up the price of a comic book by $75\%$ which means he increases the price of the book by $75\%$ and then sells it to the comic dealer.

We have to find out how much will he charge the comic book dealer.

New price of the book after lamar marks up the price is given by

New price $= \$4 + \frac{75}{100} \times \$4$

= $\$4 + \$3$ $= \$7$

Thus, lamar will charge $\$7$ to the comic dealer for a comic book.

Is the square root of 225 a rational number?

MArishka [77]

Step-by-step explanation:

$\text{The principal square root}:\\\\\sqrt{a}=b\iff a^2=b\ \text{for}\ a\geq0\ \text{and}\ b\geq0.\\\\\text{The square root:}\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\\===================$

$\text{If you want the principal square root (arithmetic square root):}\\\\\sqrt{225}=15\ \text{because}\ 15^2=225\\\\\text{If you want square root (algebraic square root):}\\\\\sqrt{225}=\pm15\ \text{because}\ (-15)^2=225\ \text{and}\ 15^2=225$

What is the value of x if AP and BP are tangent segments AP = 10x - 15 and BP = 7x + 3

worty [1.4K]

If AP and BP are tangent segments connected outside of the circle at point "P" then AP = BP so,
10x - 15 = 7x + 3
3x = 18
x = 6
