PLEASE HELP! I DONT UNDERSTAND! 98 POINTS! AND I ALREADY HAVE THE GRAPH!!! A FedEx freight truck carries three tons of packages 660 miles on 90 gallons of diesel fuel from Miami, FL to Atlanta, GA. FedEx makes a graph to represent the miles per gallon the truck uses.What is the domain in this situation? explain you answer.

What does the origin of the graph represent in this situation? explain your answer

Answers

Answer 1

Answer:

Answer:

See below

Step-by-step explanation:

Domain

The domain is the x value. They go alphabetically.

domain = x value

range = y value.

The domain for this situation is 0 to 90 gallons

domain: 0 ≤ x ≤ 90. The domain is between 0 and 90.

As the truck moves, each gallon of gas on the x axis moves it closer to it's destination 660 miles away (Atlanta Ga)

The slope of the graph is the rate of gas consumption. slope = miles / gallons.

slope = 660 / 90

slope = 7.33 miles per gallon. You are not asked for this but it might help you understand what the domain represents. Every gallon used in the domain allows you to travel another 7.33 miles.

Origin

The origin is (0,0). It means that the Fedex truck has not moved at all when the trip began. It has gone 0 miles and used 0 gallons of diesel fuel.

Answer 2

Answer:

If you divide 660 by 90, we see that the unit rate for this graph is 7.333 repeating, or 7 1/3. So it shows the unit rate.

The domain is anything that can be divided by 7 1/3.

The origin of the graph represents the coordinates for every other point on the graph.

Answers

Answer:

Angle E has $120\°$

Step-by-step explanation:

we know that

Observing the figure, according to the protractor

Angle B has $30\°$

Angle C has $50\°$

Angle D has $90\°$

Angle E has $120\°$

Angle F has $140\°$

the volumes of two spheres are 729 in3 and 27 in3. what is the ratio of their radii, rounded to the nearest whole number?

Answers

The volumes of spheres are proportional to R³. So their 'R's
are proportional to ∛their volumes.

(729/ 27) = 27

∛27 = exactly 3 . No rounding required.

If figure X is inscribed in figure Y, which statement must be true?A.Figure Y is circumscribed about figure X.
B.Figures X and Y are congruent.
C.Figures X and Y are polygons.
D.Figure X is circumscribed about figure Y.

Answers

Figure Y is circumscribed about figure X, Therefore , Option A is the correct answer.

What is the meaning of Inscribed and Circumscribed ?

Inscribed mean when a figure is in interior of another figure such that only its vertices touches the outer figure ,

While Circumscribed means just the opposite , A figure is called circumscribed when it covers a figure in its interior such that the figure touches only the vertices of the inner figure.

So if it is given in the question that figure X is inscribed in figure Y

They cannot be congruent .

They cannot be proved polygons.

The only option left and correct is

Figure Y is circumscribed about figure X.

Therefore , Option A is the correct answer.
