Answer:

(For the first two questions I do believe that you will need a protractor to calculate the angles.)

15) $-(\frac{7\pi }{18} )\\$ measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)

The first image attached shows where the angle should be located.

16) $\frac{\pi }{3}$ is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))

17) 350° is $\frac{35\pi }{18}$ or 6.11 (the answer depends on the format the professor wants.)

18) 240° is $-(\frac{4\pi }{3})$ radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)

The width of a rectangle is 6 2/3 inches.The length of the rectangle is twice its width. What is the perimeter of the rectangle?

Makovka662 [10]

In this question , it is given that , the width of a rectangle is 6 2/3 inches.The length of the rectangle is twice its width.

First we need to convert mixed fraction to improper fraction.

$width = 6 \frac{2}{3} = \frac{20}{3}$

And length is twice of width, so length is

$length = 2* \frac{20}{3} = \frac{40}{3}$

The formula of perimeter is two times the sum of length and width.

$Perimeter = 2(\frac{20}{3} + \frac{40}{3} ) = 2( \frac{60}{3}) = 2*20 = 40 inches$

Which points lie on the line that passes through point P and is parallel to the given line? Check all that apply.

11111nata11111 [884]

Answer:

(-1, 3), (-2, 2) and (-5, -1) lie on the line.

Step-by-step explanation:

Let the equation of the line which is parallel to the given line is y = mx + c

Here m is the slope of line similar to the line given = (y - y')/(x - x')

Here (x, y) and (x', y') are (4, 2) and (-2, -4)

then m = (2+4)/(4+2) = 6/6 = 1

Now the equation of the line will be y = x + c

This line passes through point P(0, 4)

4 = 1×0 + c

c = 4

Therefore equation of the line will be

y = x + 4

Now we check for each point given in the question whether it lies on the line or not.

For (-4, 2)

y = (-4) + 4 = 0

Hence not lies on the line.

For (-1, 3)

y = (-1) + 4 = -1 +4 = 3

Hence (-1,3) lies on the line.

For (-2, 2)

y = (-2) + 4 = -2 + 4 = 2

Hence (-2, 2) lies on the line.

For (4, 2)

y = 4 + 4 = 8

Hence (4, 2) lies on the line.

For (-5, -1)

y = -5 + 4 = -1

Hence (-5, -1) lies on the line.

Therefore (-1, 3),(-2, 2) and (-5, -1) lie on the line.

Answer:

I believe it would be likely.

Step-by-step explanation:

If it landed on the honey side up 8 out of 40x then that is only a 20% chance of the honey side facing up. I it would be more likely for the honey side to face down.
