The Smith family has five members: Mom, Dad, Ed, Lisa, and Judy. Each family member owns a dog. The family and their dogs were out hiking when they encountered a river they needed to
cross. They rented a boat which could hold three living things (people or dogs). Unfortunately,
the dogs were temperamental: each was comfortable only with its owner and could not be near
another person, not even momentarily, unless its owner was present. Dogs could be with other
dogs, however. The crossing would have been impossible except that Lisa's dog had attended a
first-rate obedience school and knew how to operate the boat. No other dogs were that well-
educated. How was the crossing arranged, and how many trips did it take? (Note: Lisa's dog,
though well-educated, was just as temperamental as the other dogs.)

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.

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
