Answer: True</h3>
Explanation:
All direct proportion equations are <u>straight lines</u> that go through the <u>origin</u>.
In this case, the constant of proportionality is 5 because of the following
- y/x = 5/1 = 5
- y/x = 10/2 = 5
- y/x = 15/3 = 5
- y/x = 35/7 = 5
- y/x = 50/10 = 5
Each x,y set of values are selected from the points in the graph. The equation of the green line is y = 5x with slope 5 and y intercept 0.
Furthermore, that slope 5 indicates that the unit rate is 5 gallons per minute.
Here you should add the like terms; so 6 + 3 = 9 and 5*(sq.root of 5) - 2*(sq.root of 5) = 3*(sq.root of 5), therefor the answer would be 3*(sq.root of 5) + 9
Remember that surds can be added or subtracted if the term underneath the square root sign is the same :)
Answer:
the angle of x measures 16.6
The median of the data in the box plot is 6.
The first quartile is 5.5 (median of first half of data set)
The third quartile is 7 (median of upper half of data set)
The lower extreme is 3.5 (lowest number in the data set)
The upper extreme is 7.5 (highest number in the data set)
A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N
(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America
E = 2N
E = 2(23)
E = 46 <== Europe
A = 7 + E
A = 7 + 46
A = 53 <=== Africa
