A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.

Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.

Hey

I hope you are having a great day

The answer would be A librarian had 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then  150/k is the number of books on each shelf.

Explanation: Lets see Option 1 is obviously out Option 2 does not make

sense  When it comes to option 3 that makes the most sense Option 4 could  be right but option 3 is the best and correct answer

So that's your answer

Hope This Helps :)

What if X if [ -1 -2 4 8] +X= [-5 -1 2 1]?
Arada [10]

Answer:

[-4 1 -2 - 7]

Step-by-step explanation:

[-1 - 2 4 8] + X = [-5 - 1 2 1]

X= [-5 - 1 2 1]- [-1 - 2 4 8]

X=[-5-(-1) - 1-(-2) 2-4 1-8]

X=[-4 1 - 2 - 7]

5) In the figure, triangle ABC is a right triangle at B. If CD = 15, find BC to the nearest tenth.
ycow [4]

Answer:

BC ≈ 4.0

Step-by-step explanation:

∠ DCA = 180° - 70° = 110° ( adjacent angles )

∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle

∠ DAC = 180° - 140° = 40°

Using the Sine rule in Δ ACD to find common side AC

\frac{AC}{sin30} = \frac{15}{sin40} ( cross- multiply )

AC × sin40° = 15 × sin30° ( divide both sides by sin40° )

AC = \frac{15sin30}{sin40} ≈ 11.668

Using the cosine ratio in right triangle ABC

cos70° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{11.668} ( multiply both sides by 11.668 )

11.668 × cos70° = BC , then

BC ≈ 4.0 ( to the nearest tenth )
