Adrian drives to school and back each day. The school is 16 miles from his home. He averaged 40 miles per hour on his way to school. If his total trip takes 1 hour, at approximately what average speed does Adrian drive home?

26 mph

Step-by-step explanation:

First find the time Adrian takes to get to school

I found it easiesT to use the method of ratio and proportion

40:60

16:x

x= 16 x 60 / 40 = 24 minutes

So, he has 60-24 minutes to return home, that is 36

What is his speed if his time is 36 minutes= 0.6 hours

Speed = Distance divided by time = 16/0.6 = 26.6 miles per hour.

Hope this helps

Good Luck

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
