Two students measure their reaction times by seeing how many seconds it takes one of them to catch a yard stick that the other d

rops right above his hand. Suppose the radical √0.08 represents the time it takes one of the students to catch the ruler, and √0.18 represents the time it takes the other student to catch it.
It also asks to make an expression to represent the difference between the two reactions.

Please help!!

Vsevolod [243]

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

<u>Question asked:</u>

What is the approximate length of the arc of the section containing the peas?

<u>Solution:</u>

The central angle formed by the peas = 360° - 105° - 203°

                                                                = 52°

Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches

As we know:

Length\ of\ arc=2\pi r\times\frac{\Theta }{360}

                        =2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.

Answer:

See below

Step-by-step explanation:

I can't draw it for you so here are the points.  Draw your triangle with them.

From the original triangle, to rotate 180 degrees around the origin, just imagine your are flipping your computer screen upside down which is 180 degrees.  To get the coordinates for the points, just make each x and y value the opposite of what the origin is.

Original points  ( 2, 1 )      ( 5, -2 )    ( 3, -4 )

Rotated points  ( -2, -1 )    ( -5, 2 )    ( -3, 4 )

nearest tenth?

= 2 because after 1. is 7 and when you round it to the nearest ten  it will be 10, so it's a whole. so then that means that it would be 2.
