Lia must work at least 5 hours per week in her family’s restaurant for $8 per hour. She also does yard work for $12 per hour. Li
Sedaia [141]
Hello,

As the question states, let r be the number of hours worked at the restaurant, and y be the number of hours of yard work. We know that she can only work a maximum of 15 hours per work total, and that at she must work at least 5 hours in the restaurant. Therefore:r + y ≤ 15r ≥ 5We also know that she wants to earn at least 120 dollars, earning $8/hr in the restaurant and $12/hr in the yard:8r + 12y ≥ 120
What is the maximum of hours Lia can work in the restaurant and still make at leas 120 hours? Lia's parents won't let her work more than 15 hours, so we know that the answer won't be higher than 15.If she worked all 15 hours in the restaurant, she would make 8*15 = 120.The maximum number of hours she can work in the restaurant is therefore 15 hours
What is the maximum amount of money Lia can earn in a week? Lia has to work a minimum of 5 hours in the restaurant. She makes more money doing yard work, so she should devote the rest of her available work hours to yard work. That means that, given her 15 hour work limit, she will maximize her income by working 5 hours in the restaurant and 10 hours in the yard. 5*8 + 10*12 = 40 + 120 = 160The most she can make is 160 dollars, working 5 hours in the restaurant and 10 hours in the yard

Hope this helps

What is m∠CAD?
marusya05 [52]
Exterior Angle Theorem: The measure of an exterior angle is equal to the sum of its 2 remote interior angles (That don't form a linear pair with it)

So its 25 + 90 = 115 (D)
ALSO it clearly cant be A because if you look at the angle, its greater than 90 degrees.

LUCKY_DIMON [66]
Lets analyze the equation:
<span>ax^2 - bx = 0
</span>x(ax - b) = <span>0
</span>Therefore if x = 0, the equation holds no <span>matter about a and b</span>:
0(0a - b) = 0
0 = 0

coldgirl [10]

Answer:

C) 15

Step-by-step explanation:

This is an isosceles triangle (two of the three angles are equal) so two of the sides are also equal. x is the same length as 15.
