Yes he can, he could do:
1 : 46
2 : 45
3 : 44 and so on
Answer: B. 5/13
This is the same as writing
==========================================================
Reason:
We have two given sides of this right triangle. Use the pythagorean theorem to find the missing side.
a = 5 and b = 12 are the two known legs; c is the unknown hypotenuse
The hypotenuse is exactly 13 units long. This is a 5-12-13 right triangle.
Now we can compute sine of theta
This points us to choice B as the final answer.
----------------
Extra Info (optional)
- 5/12 is the value of tan(theta) since it's opposite/adjacent
- 12/5 is the value of cot(theta), the reciprocal of tangent
- 12/13 is the value of cos(theta), because cos = adjacent/hypotenuse
Answer:
10 bouquets were sold today
Step-by-step explanation:
First, we need to find how much money the flower stand made the day it sold a dozen (12) bouquet at $10 each.
Total Selling Price = Number of items × Price of each item
Total Selling Price = 12 × $10 = $120
Today, the bouquets were sold at $12, for the <em>same total selling price of $120</em>, so the number of bouquets sold, using the above formula will be;
Number of Items = = = 10 bouquets
For 10 rows, she takes = 12 min.
So, for 1 row, she'll take = 12/10
Now, for 15 rows, it would be: 12/10 * 25 = 12/2 * 5 = 60/2 = 30
So, Your Final Answer would be 30 minutes
Hope this helps!
