We know that 5 lbs of apples cost $2.99
To know how much do 3 lbs of apple cost, you can use cross multiplication
If 5 lbs cost $2.99
Then 3 lbs cost $x
The proportion between the price and the number of apples is the same, you have to calculate it as:
3 lbs of apples cost $1.79
Let <span>sin(90° - )------------------------ > sin (90-x)
</span>sin(a - b<span>) = sin a*cos b - cos a*sin b
</span><span>so
</span>sin(90 - x) = sin 90*cos x - cos 90 * sin x
sin(90 - x) = 1*cos x - 0* sin x-------- > cos x
the answer is the option <span>D. cos()</span><span>

Answer:
Cannot be determined
Step-by-step explanation:
There is not enough information to solve this question. You would need to know how many friends he has in order to solve this.
First, multiply both sides by 88, because you can divide 88 by 22. That final would be 3k*88/22 = -13. Simplified, that would be 12k = -13. Divide both sides by 12, making the final answer k = -12/13, or in decimal form 1.08333...
