Answer:
Because it is a mixed fraction and it should be renamed in order to solve your problem, for the other one CAN NOT be converted into a mixed fraction.
Answer: The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.

Answer 2 line segments are parallel to FE
Dad = d
Carolyn = 1/2d
1/2d + d = 75
d = 50
1/2(50) + 50 = 75
25 + 50 = 75
75 = 75
Carolyn = 25 years
Caleb = 50 years
Hope this helps =)
Answer: perimeter = 62
Step-by-step explanation:
To determine the length of the unknown sides of the triangle, we would apply the sine rule which is expressed as
a/SinA = b/SinB = c/SinC
Therefore
AB/Sin 40 = 19.5/Sin 49
ABSin49 = 19.5Sin40 = 19.5 × 0.64
0.755AB = 12.48
AB = 12.48/0.755
AB = 16.5
The sum of the angles in a triangle is 180°. Therefore,
A = 180 - (40 + 49) = 91°
BC/Sin 91 = 19.5/Sin 49
BCSin49 = 19.5Sin91 = 19.5 × 0.9998
0.755BC = 19.5
BC = 19.5/0.755
BC = 25.8
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = a + b + c
Where
a, b and c represents the length of each side of the triangle.
Perimeter of triangle = 25.8 + 16.5 + 19.5 = 62
