11. MARINE BIOLOGY Killer whales usually swim at a rate of 3.2-9.7 kilometers per hour, though they can travel up to 48.4 kilometers per hour
Suppose a migrating killer whale is swimming at an average rate of 4.5
kilometers per hour. The distance d the whale has traveled in t hours can b
predicted by the equation d = 4.51.
a. Graph the equation.
b. Use the graph to predict the time it takes the killer whale to travel 30
kilometers.

a. is correct

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
