Answer:
The answer is D, as the trapezoid will not change at all due to the fact that it is just being rotated. (Rotations do not change a shape's measures or shape). :)
Step-by-step explanation:
A) n-20
b.)30=1/2n+1/2
c.)2/3n=30
d.)5n=90
e.)M•3+4=49
19/x=sin 20
19/sin 20=x
x=55.5522836
You divide 1 by 4.76 and you get 0.21 as your main answer
We can first convert 9.5 into fraction :
9.5= 9 1/2
Then we can use deduction to find out the answer:
9 1/2 - 6 1/3
=19/2 - 19/3
We change it to the same denominator:
=19×3/6 - 19×2/6
= 57/6 - 38/6
= 19/6
Therefore there are 19/6 or 3 1/6 gallons left in the tank.
Hope it helps!
