Answer:
C
Step-by-step explanation:
Triangle CGF and triangle CED are similar. Hence, the ratio of their corresponding sides are equal. Thus we can write:
<em>We can now cross multiply and solve for CD:</em>
Since GF is a midsegment of CDE, CD is double of CF. So we can write:
<em>By using quadratic formula and with a=3, b= -5.2, and c= -1.6, we find the value of x to be:</em>
<em>Since the expression for CD is , we plug in
into this expression to find value of CD:</em>
The correct answer is C
Answer:
<h2>The factory needs to sell 327 packbacks to make at least 9,800 per week.</h2>Step-by-step explanation:
We know that each backpacks is sold for $40.00.
The goal is to make at least $9,800 per week. With this information we can define the inequality
Where represents backpacks. Notice that this inequality is about profits, that's why we subtract the cost from the sell price, in this case, the profid margin is $30.00 per backpack, so
Solving for
Therefore, the factory needs to sell 327 packbacks to make at least 9,800 per week.
