Answer:
b.) 2
Explanation:
Parallel slopes have same slope.
Perpendicular slopes have negatively inverse slope.
Comparing it with slope intercept form, "y = mx + b" where m is slope.
Here parallel slope: -1/2
Perpendicular slope: -(-1/2)⁻¹ = 2
False, False, True
**********
The first is false since the square root of 19 is 4 and 4/7 is not a whole number
The second is false since the square root of 40 is 6.32 which is less than 7
The last is true because the square root of 30 is 5.48 and that makes the fraction equal 3.65 which again is a whole number while 2/3 is not
Answer:
A). Scale factor =
B). Length of the unknown side = 2.75 feet
Step-by-step explanation:
Part A
Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor =
=
=
=
Part B
Scale factor =
Therefore, side length of the unknown side = = 2.75 feet
1 ton = 2,000 pounds, so 1 ton would of course weigh more than 388 pounds
