One brand of motorcycle uses an oil-to- gasoline ratio as shown in the graph. The
amount of oil that should be added varies
directly with the amount of gasoline. Write
a direct variation equation that describes
the relationship. Use your equation to
determine the amount of oil that should
be added to 6.5 gallons of gasoline.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the diver is 33 feet below the surface.
