Answer:

  • x > 6
  • 6 < x < 62

Step-by-step explanation:

<h3>Question 5</h3>

The sides containing the given angles 37 and 84 are of same length:

one side is marked same, the second side is common.

<u>The sides opposite angles of 37 and 84 are proportional to those angles, therefore:</u>

  • 0< x + 14 < 2(3x - 8)

<u>The first part:</u>

  • x > - 14

<u>The second part:</u>

  • x + 14 < 6x - 16
  • 5x > 30
  • x > 6

<u>Combination of the two is:</u>

  • x > 6
<h3>Question 6</h3>

<u>The triangles are isosceles, because:</u>

  • The left triangle has two equal angles, so the opposite sides are congruent
  • The common side with the right triangle is same as marked side, so the triangle on the right is also isosceles.

The angles between equal sides

<u>Left triangle:</u>

  • 180° - 2*70° = 40°

<u>Right triangle:</u>

  • 180° - 2*66° = 48°

<u>Since 40° < 48°, the opposite sides will have same inequality due to being proportional to angles:</u>

  • 3x - 18 < 2(x + 22)
  • 3x - 18 < 2x + 44
  • 3x - 2x < 44 + 18
  • x < 62

<u>Same time we know the side must be a positive number:</u>

  • 3x - 18 > 0
  • 3x > 18
  • x > 6

<u>So the possible values of x are:</u>

  • 6 < x < 62 or x = (6, 62)

Explain how you can use place value patterns to describe how 50 and 5000 compare
salantis [7]
The place value pattern is a system of patterns of tens in which every place value is ten times the value on its right. The place value pattern system is used to <span>write numbers that are 10 times as much as or 1/10 of any given number. 
The place values in the pattern are: ones, tens (10*ones), hundreds (10*tens), thousands (10*hundreds),...
So, 50 = 5 tens 
       5000= 5 thousands, 0 hundreds, 0 tens, 0 ones

So, 5000 > 50</span>

A cylindrical tank has a radius of 15 ft. and a height of 45 ft. How many cubic feet of water can the tank hold?
vladimir1956 [14]
The formula to solve for this would be pi(r^2)xheight. Essentially what this formula does is it takes the are of the base (pi x r^2) and multiplies it by the height of the cylinder to find how many times the base can stack on itself until it reaches the top. This formula of base are times height works for all prisms with two bases. Here are the steps to solve:

1) plug in the values
- pi(15^2) x 45

2) solve for the base area of one of the circles
- pi(15^2)=225pi

3) multiply the base area by the height
- 225pi x 45 = 10,125pi

4) final answer: the tank can hold 10,125pi cubic feet of water

Braving blizzard conditions on the planet Hoth, Luke Skywalker sets out at top speed in his snowspeeder for a rebel base 4800 mi
____ [38]

Answer:

v_top = 2400 mi/hr

v_w = 400 mi/h

Step-by-step explanation:

Given:

- Total distance D = 4800 mi

- Headwind journey time taken t_up= 3 hr

- Tailwind journey time taken t_down = 2 hr

Find:

Find the top speed of Luke's snow speeder and the speed of the wind.

Solution:

- The speed of Luke v_l is in stationary frame is given by:

                           v_l = v_w + v_l/w

Where,

           v_w: Wind speed

           v_l/w: Luke speed relative to wind.

- The top speed is attained on his returned journey with tail wind. We will use distance time relationship to calculate as follows:

                         v_top = D / t_down

                         v_top = 4800 / 2

                        v_top = v_down = 2400 mi/hr

- Similarly his speed on his journey up with head wind was v_up:

                         v_up = D / t_up

                         v_up = 4800 / 3

                        v_up = 1600 mi/hr    

- Now use the frame relations to find the wind speed v_w:

                         v_down = v_w + v_l/w

                         v_up = -v_w + v_l/w    

- Solve equations simultaneously:

                         2400 =  v_w + v_l/w

                         1600 =  -v_w + v_l/w

                         4000 = 2*v_l/w

                         v_l/w = 2000 mi/h

                         v_w = 400 mi/h

Consider the line =+3x6y−8 . what is the slope of a line parallel to this line? what is the slope of a line perpendicular to thi
Reil [10]
<span>Two lines are parallel if their slope is the same.
You want to write 8x + 4y = 5 in the form y = mx + b, where m represents the slope and b is the y-intercept.
We need to isolate y in the given equation. The number next to x is the slope.
8x + 4y = 5
4y = -8x + 5

y = (-8x +5)/4
y = -2x + 5/4
The slope of the line we want is -2.
Two lines are perpendicular if the slope of the first line times the slope of the second line produces a product of negative one.
Since our slope is -2, we know that -2 times 1/2 yields -1.
The slope of the line perpendicular is 1/2. </span>
