5a)

2x + 94 = 7x + 49 (vertical angles are equal)

2x - 7x = -94 + 49

-5x = -45

x = 9

Answer

9

5b)

4y + 7x + 49 = 180 (supplementary angles, sum = 180)

4y + 7(9) + 49 = 180

4y + 112 = 180

4y = 68

y = 17

Answer

17

6)

x = 6x - 290 (vertical angles are equal)

-5x = -290

  x = 58

Answer

58

A cylinder has a Height 12 and a radius 3.7 what is it’s volume?
Juli2301 [7.4K]
The formula for the volume of a cylinder is v = π r² h 
Let's use 3.14 for π. 
Square 3.7 to get 13.69. 
Multiply that by 3.14. 
v = 42.9866 x 12 
Finally, multiply it by 12. 
v = 515.8392

You could also express your answer in terms of pi. 
Square 3.7 to get 13.69. 
Multiply it by 12. 164.28 is what you get.
v = 164.28π 

Hope this helps!

Based on the bar chart given, it could be seen that the x axis which is labeled days of the week is not adequately spaced. Data on both axis should he a recognizable.

2.)

Taking a look at the graph, it has no origin, the numbering of the vertical axis, number of text messages should start from 0

3.) Also, the x and y axis aren't labeled Hence charts should be well labeled to include x - axis and y-axis.
