tensa zangetsu [6.8K]

Answer:

5^2+h^2=12^2, the answer would be ~10.97 ft.

Step-by-step explanation:

I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.

Pythagorean theorem is :

a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.

Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

Yanka [14]

Answer:

It will take 1 week for both classmates to catch up with each other
Each child has passed about 9 tests.

Step-by-step explanation:

We know that:

Q = 8 + 1(w)
S = 4 + 5(w)
Q = S

Work:

8 + w = 4 + 5w
=> 8 - 4 = -w + 5w
=> 4 = 4w
=> w = 1

Hence, it will take 1 week for both classmates to catch up with each other. Now, let's substitute the value of w into the first equation to find how many tests have each child passed.

Q = 8 + (w)
=> Q = 8 + 1
=> Q = 9

Hence, each child has passed about 9 tests.

Hoped this helped.
