Horizontal and parallel lines e and f are cut by transversal b. At the intersection of lines b and e, the uppercase right angle
spayn [35]

Answer:

130

Step-by-step explanation:

From the FIQURE of the question, we can see that line "e" is parallel to line "f" then we can say (2x + 18)=( 4x - 14)

Then we can collect like terms

2x-4x= -14-18

-2x=-32

The negatives cancelled out we have

x = 16

From the question, At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees

Angle on a straight line is 180° then we can calculate "y" as

y = 180 - (4x - 14)

= 180-4x+14

= 180+14-4x

But x= 16, then substitute we have

= 180 +14 - 14(16)

= 130

Hence, the value of y is 130

The dot plots below show the runs scored in each of the first games of the season by the Hawks and the Eagles. Runs Scored (Ha R
omeli [17]

Answer:

Part B: 8 and 2 (more answers ofc)

Part C: Two more dots on 6 (more than one answer tho)

Step-by-step explanation:

<em>Part B:</em>

The added number of dots is 39 at the beginning and the mean is 3.9. (39/10). Since we have to add 2 dots the equation will be (<em>39 + ? + ?) / 12 = Less than 3.9</em>. We also need the range to increase. This means that one of the blanks must be larger than 7 (the largest dot on the dot plot!) I just went with 8 to keep the mean as small as possible. This leaves 1 more blank to figure out. There are multiple answers to this problem but I went with 2 just because then the mean would be 3.5 a better answer than something like 3.58333333333.

<em>Part C:</em>

If you think about it all the dots added up should be 6x12 = 72. Currently all the dots add up to 60. 72-60 is 12. This means that 12 is equal to 2 dots. I guess you could also do 5 and 7, 8 and 4, etc.

36 * 4 walls = 144 total minutes

144/6 people = 24 minutes total
