Triangle ABC was rotated about the origin. Which rule

Nuetrik [128]

<h3>Answer: Choice A $R_0, 90^{\circ}$ </h3>

The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing $R_0, 270^{\circ}$ is not correct as we don't rotate 270 degrees counterclockwise.

In a poll, 6 out of 13 children said they read every night before bed, whereas 54% of the adults said they read every night befo

Tpy6a [65]

To answer this question you must find the percentage of the children that read before bed and compare it to the adults bag read before bed’s percentage.
To do this, start by dividing the number of children that read before bed by the total number of children surveyed.
This leaves you with:
6/13= 0.4615

To find the actual percentage, multiply this result by 100.
0.4615 x 100 = 46.15
This percentage rounded is 46%

So, now you can compare the percentages. The percentage of children that read before bed is 46% and the percentage of adults that read before bed is 54%. So, the group with the greatest percentage was the adults.

I hope this helps!

<u><em>Explanation:</em></u>

The ground, the plane to climb and the altitude (100 m) all form a right-angled triangle

Therefore, we can apply the special trig functions.

<u>These functions are as follows:</u>

sin(θ) = $\frac{opposite}{hypotenuse}$
