Write 19/25 as a decimal fist person to answer the question correctly is going to be the brainliest

So basically to change this to a decimal, you want to first change the denominator to 100. You can do this by multiplying the fraction by 4/4, which is still 1, but just with a denominator of 4.

19/25 * 4/4 = (19*4) / (25 * 4) = 76 / 100

So now you can just convert this to a decimal, and say 0.76.

Answer: Choice A

$\frac{\sqrt{6}+\sqrt{2}}{4}$

========================================================

Work Shown:

$\cos(30) = \frac{\sqrt{3}}{2}$

$\cos(\frac{x}{2}) = \sqrt{\frac{1+\cos(x)}{2}$

$\cos(\frac{30}{2}) = \sqrt{\frac{1+\cos(30)}{2}$

$\cos(15) = \sqrt{\frac{1+\frac{\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{\frac{2}{2}+\frac{\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{\frac{2+\sqrt{3}}{2}}{2}$

$\cos(15) = \sqrt{\frac{2+\sqrt{3}}{4}}$

$\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{\sqrt{4}}$

$\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{2}$

$\cos(15) = \frac{0.5\sqrt{6}+0.5\sqrt{2}}{2}$

$\cos(15) = \frac{\sqrt{6}+\sqrt{2}}{4}$

#1 What is the explicit equation of the sequence 10125, 2025, 405, 81, ..? *

vazorg [7]

405/81=5
10125/2025=5

It seems like it divided by 5 each time.

So, the nth term of the sequence is (50625)n^(-5)

Scientists have increased their ability to make observations beyond their own senses through the invention of specialized equipm

just olya [345]

Answer:

Step-by-step explanation:

A is rather a strange choice. The tools are used as extensions of our senses. That's all that technology has done. We still need to observe things for ourselves if we are to learn. I actually really do not know what this statement means. My answer reflects what I think is true. Our need to observe and think is not hindered.

B is never going to be true. We still have to test things out, even with the best tools that we have.

C: The exact opposite is true. Our knowledge of the universe has expanded beyond our belief with the better tools of technology that we have.

D: This is the opposite of C and is the answer.
