Answer:

The path is 17 ft long.

Step-by-step explanation:

Let <em>c</em> represent the length of the hypotenuse of a right triangle, and let <em>a</em> and <em>b</em> represent the lengths of its legs, as pictured in the image below.

The relationship involving the legs and hypotenuse of the right triangle, given by

a^2+b^2=c^2

is called the Pythagorean Theorem.

The diagonal of the rectangle is equivalent to finding the length of the hypotenuse of a right triangle with sides 8 feet wide and 15 feet long.

Applying the Pythagoras' Theorem, we get

d^2=(8)^2+(15)^2\\d^2=64+225\\d^2=289\\d=\sqrt{289}=17

Technically, there are two answers to d^2=289, i.e., d = 17 or d = -17. However, d represents the hypotenuse of the right triangle and must be non-negative. Hence, we must choose d = 17.

The path is 17 ft long.

What is the surface area of the regular pyramid
Ugo [173]

Answer:

The answer is 144.

Step-by-step explanation:

Cause, 6 x 6 for the square is 36. For the triangle, 9 x 6 is 54, and 54 divided by 2 is 27. 27 x 4 is equal to 108. Now, we just add 108 and 36 to make 144.

At noon joyce drove to the lake at 30 mph, but she made the long walk back home at 4 mph. how many hours did she walk if she was
lina2011 [118]
By definition we have the following equation:
 t = d / v
 Where,
 t: time
 d: distance
 v: speed
 For this case we have:
 d / 30 + d / 4 = 17
 Rewriting we have:
 2d + 15d = 17 (60)
 17d = 17 (60)
 d = 60 mi
 Then, the walking time is
 t = d / v
 t = 60/4
 t = 15 hours
 Answer:
 
She walked
 
t = 15 hours

Answer:

m=17/40  \frac{17}{40}

Step-by-step explanation:

So you 5/7m - 1/7 = 9/56 \frac{5}{7}m - \frac{1}{7} = \frac{9}{56}

You Simplify both sides Then

well I Don´t know I hope this helped u, I tried ^^¨
