In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .

= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )

= 25 + 25 = x²

= 50 = x²

= 7.0710678119 = x

But they have given that we have to round it off to the nearest tenths , so ;

= 7.0710678119 will be equal to = 7.10

= 7.1 = x

Therefore , the length of the unknown side x = 7.1 .

Virty [35]

Answer:

raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. (given)

thus, rate of draining of water gallons per minute = -1.5

amount of water remaining in the bathtub = y,

the function of the time in minutes that it has been draining = x, .

at 0 minutes the amount of water is 40 gallons.

thus,the volume of water is 40 is decreasing at the rate of 1.5 gallons per minute

the given function is a linear function  

y = 0

however, the volume of water can be 0 but cannot ever be negative.

thus, the range of y will be all real numbers such that 0≤y≤40

Step-by-step explanation:

Marco is coaching football 24 out of 30 days in June which decimal is equivalent to the fraction of days until he coach football
Sergio [31]

Answer:

Since the fraction of this is very obviously 24/30, here's how you can get a decimal out of that:

First, you simplify that fraction.

24/30 = 4/5, since 5x6 is 30 and 6x4 is 24

Now, it's pretty easy to convert 4/5 into a decimal.

This is how I like to do it. You re-convert the fraction one step higher, so it's 8/10, and you just turn it into 0.8, since it's all out of 10.

I hope I helped, and I'd appreciate a "Brainliest"! ☺
