Part A:
What is the cost of 5.15 pounds of ground beef, if 1 pound = $3.40
Multiply the cost of 1 pound per how many pounds there are:
3.40 * 5.15 = $17.51
It costs $17.51 for 5.15 pounds of ground beef at $3.40 per pound
Part B:
Assuming the cost of the burger is only determined by the cost of ground beef.
The cost of the 17 burgers is $17.51
We divide $17.51 by 17, to find out the cost of each burgr
$17.51 / 17 = $1.03
The cost of ground beef per burger is $1.03
It is an angle that is making a right angle to another line
X^2+6x=68 I think but I’m not sure
1st Step: Use Pythagorean Theorem.
2nd Step: Use inverse trigonometry to find an angle.
3rd Step: Subtract two known angles from 180° to find the missing angle.
