Brooke cooked a 4/1/3-pound lasagna in 1/1/3 hours. How many hours per pound did it take to cook the lasagna?
Hitman42 [59]

Answer:

4/13 hours

Step-by-step explanation:

Total pounds of lasagna = 4 1/3 pounds

Total time taken to cook = 1 1/3 hours

How many hours per pound did it take to cook the lasagna?

Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna

= 1 1/3 hours ÷ 4 1/3 pounds

= 4/3 ÷ 13/3

= 4/3 × 3/13

= 4/13 hours

It will take 4/13 hours to cook each pound of the lasagna

In the diagram below, BC is an altitude of ABD. To the nearest whole unit, what is the length of CD?
sergiy2304 [10]
For the answer to the question above, I'll show my solution on how you can solve your problem.
AC² + BC² = AB² 
<span>5² + 12² = AB² </span>
<span>25 + 144 = AB² </span>
<span>169 = AB² </span>
<span>13 = AB </span>

<span>Triangle ABC is proportional to triangle ADB. </span>

<span><u>AC </u>= <u>AB </u></span>
<span>AB    AD </span>

<span><u>5</u> = <u>13 </u></span>
<span>13  AD </span>

<span>5AD = 169 </span>

<span>AD = 169/5 </span>

<span>AD = 33.8 </span>

<span>AD = AC + CD </span>

<span>33.8 = 5 + CD 
</span>So the answer is

<span>CD = 28.8 </span>
