Answer:
225 in
Step-by-step explanation:
Using proportions, it is found that it will take him 22.5 hours to walk the 45 dogs.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
He walks 3 dogs in 1 hour and 30 minutes, we means that the time in hours it takes for him to walk a dog is:
t = 1.5/3 = 0.5 hours.
Hence the time it will take him to walk 45 dogs is given by:
45 x 0.5 = 22.5 hours.

Answer:
the x should be 10x7-(9x6)
Step-by-step explanation:
because it should be 10x7-(4+30)
False, it would not make a right triangle
These are congruent angles. So they would be equal to each other. 6x=4x+50
2x=50
x=25°
