Answer:
you can fit 1000 hairs in 10 cm
Step-by-step explanation:
![10^2= .01](https://tex.z-dn.net/?f=10%5E2%3D%20.01)
![.01*1000 = 10](https://tex.z-dn.net/?f=.01%2A1000%20%3D%2010)
Answer:
-1215.
Step-by-step explanation:
For a geometric sequence:
nth term = a1 r^(n-1)
The first term a1 = 5 and the common ratio r = -15/5 = -3.
So 6th term = 5 * (-3)^(6-1)
= 5 * (-3)^5
= -1215.
B, is the correct answer If its wrong write me comment.
Given :
The angle of depression is 30 degrees from the bottom of the boat to a
deep sea diver a the depth of 120 ft.
To Find :
The distance x the diver must swim up to the boat to the nearest foot.
Solution :
Let, distance between diver and boat is x.
So,
![sin\ 30^o=\dfrac{h}{x}\\\\x = \dfrac{120}{\dfrac{1}{2}}\\\\x = 240 \ ft](https://tex.z-dn.net/?f=sin%5C%2030%5Eo%3D%5Cdfrac%7Bh%7D%7Bx%7D%5C%5C%5C%5Cx%20%3D%20%5Cdfrac%7B120%7D%7B%5Cdfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5Cx%20%3D%20240%20%5C%20ft)
Therefore, distance the diver must swim up to the boat to the nearest foot is 240 foot.
Hence, this is the required solution.
Answer:
3A : 3(a)+8(b)+2(c)
3B: 3(20)+8(8.50)+2(40)=208
3C: 208-15%=208*0.15=31.2
208-31.2=176.8
3D: 176.8+6%=176.8*1.06
187.41
