Answer:

Step-by-step explanation:

45=32+13

tan 45=tan(32+13)

$1=\frac{tan~ 32+tan~ 13}{1-tan ~32 ~tan~ 13} \\cross~multiply \\1-tan 32 ~tan~13=tan ~32+tan~13\\$

or 1-tan 32 tan 13-tan 32-tan 13=0

In a survey 9/25 students ride the bus and 19/50 walk to school. What fraction of students ride the bus or walk?

san4es73 [151]

Well since 19/50 can't be simplified you have to double 9/25 which is 18/50 so then add 18 + 19 = 37 So 18/50 + 19/50 = 37/50 so 37/50 of the students ride the bus or walk to school.

<u>Answer:</u>

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

<u>Solution:</u>

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