Answer:
-23/10 or-2 3/10
Step-by-step explanation:
Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is
1
number to the right of the decimal point, place the decimal number over

1908 Siberian Asteroid is known to be 130 feet/ 18 meters in
diameter while on the other hand Chelyabinsk Asteroid is known to be 59 feet/40
meters in diameter. To find how many times Siberian Asteroid is bigger than
Chelyabinsk Asteroid we just have to divide Siberian by Chelyabinsk here we
get:
10/59=2.2 = 1908 Siberian Asteroid is 2.2 times bigger than
Chelyabinsk Asteroid.
(a) Truck carries 90 gallons of diesel fuel to 660 miles.
So, 1 gallon of diesel fuel to 660/90 = 22/3 miles.
30 gallons of diesel fuel to = 220 miles.
Hence, if x-axis represents the number of miles and y-axis represents the number of gallons, then, (660, 90) and (220, 30) are points on the graph.
Join (660, 90) and (220, 30), we get the graph of a line.
Note that (0, 0) is also a point on the line.
Equation of the line is .
(b) x represents the number of miles. Therefore, the possible values for x is the closed interval [0, 660].
Hence, the domain of the function is [0, 660].
(c) Origin represents that the truck is not moving and there is no diesel fuel loaded in the truck.
