Step-by-step explanation:
Sin(20) = 0.91294525072 which in a fraction it would be 24/25
Answer:
A'(0, -8), B'(6, 0), C'(0, 8), D'(-6, 0)
Step-by-step explanation:
Whenever you are doing a 90° clockwise rotation ABOUT THE ORIGIN, it is in the form of [<em>y</em><em>,</em><em> </em><em>-</em><em>x</em>], meaning you take the <em>y</em><em> </em>and make it your <em>x</em><em>,</em><em> </em>then take your original <em>x</em><em> </em>and put its OPPOSITE.
90° counterclockwise rotation → [<em>-</em><em>y</em><em>,</em><em> </em><em>x</em>]
90° clockwise rotation → [<em>y, -x</em>]

Suppose s and h are the mileage numbers for the SUV and Hybrid, respectively. Then if each vehicle drives 1 mile, the total gas consumption is
.. 1/s +1/h
Then the combined mileage is
.. 2/(1/s +1/h) = 2sh/(s+h)
Option 1: s=12, h=60
.. mpg = 2*12*60/(12+60) = 20
Option 2: s=11, h=75
.. mpg = 2*11*75/(11 +75) = 1650/86 ≈ 19.2
In summary,
.. Option 1: 20.0 mpg
.. Option 2: 19.2 mpg

It usually works out best to increase the efficiency of the least-efficient contributor, as here.
Answer:
x = 7.1
Step-by-step explanation:
6.3 + 5.6 + 8.4 + x = 27.4
20.3 + x = 27.4
20.3 - 20.3 + x = 27.4 - 20.3
x = 27.4 - 20.3
x = 7.1
6.3 + 5.6 + 8.4 + 7.1 = 27.4
