Answer:
4/3 pi≈3
Step-by-step explanation:
40/360 = 1/9
S= pi*r²* n/360
S= 3*4*1 /9 = 4/3
Given:
In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.
To find:
The value of sine of ∠J.
Solution:
In a right angle triangle,

In triangle JKL,




Therefore, the value of sine of ∠J is about 0.44.
A minimum of 220 backpacks must be produced to obtain the desired benefits.
Since a company making backpacks charges $ 29.99 for each backpack, and it costs $ 6.45 to make each backpack, and the company can make backpacks in multiples of 10 and there is $ 1,000 in fixed costs, and the company wants to make at least $ 4,000 profit each week, to determine how many backpacks should be produced, the following calculation must be performed:
- 29.99 - 6.45 = 23.54
- 500 x 23.54 - 1000 = 10,770
- 250 x 23.54 - 1000 = 4.885
- 220 x 23.54 - 1000 = 4,178.80
- 210 x 23.54 - 1000 = 3,943.40
Therefore, a minimum of 220 backpacks must be produced to obtain the desired benefits.

6,500 is the answer to that question
Answer:
200 N/m
Step-by-step explanation:
Rearranging the formula F = kx, you find that k = F/x. For the first spring,
F = 36 N and x = 0.06 m (6 cm). So the spring constant, F/x, is 36N/0.06m = 600 N/m
For the second spring, F = 36 N and x = 0.09 m. F/x = 36N/0.09m = 400 N/m
The difference between these values is 200 N/m, and that's the answer.
