Rama09 [41]3 years ago
4 0

Answer:

17.5

Step-by-step explanation:

Pythagorean Theorem is a^2 + b^2 =c^2

a= 9 , b= 15, c= x

9^2 + 15^2 = c^2

\sqrt{306}= c^2

c= 17.493 or 17.5 rounded to the nearest tenth

If x varies inversley as y and x=4 when y =8, find x when y=1
nikitadnepr [17]

Answer:

x = 32

Step-by-step explanation:

If x and y vary inversely, then xy = k where k is the constant of proportion

4(8) = 32 = k

Now, xy = 32

         1(x) = 32

           x = 32

4. Ashley claims that if she triples the side length of a square (s), the area of the square will also be tripled. Do you agree?
stepladder [879]

<u>Answer</u><u> </u><u>:</u><u>-</u>

Let the side of the square measure a cm, thus, according to the question,

  • New length = 3(a cm)

We know that,

➭ Area ( Square ) = a²

Thus, the area of the square with normal length i.e. a cm, will be,

⤳ Area = a x a

⤳ Area = a²

Now, by taking the new length, the area will become,

⤳Area = 3a x 3a

⤳ Area = 9a²

Now,

We observe that, if we divide these, we get,

➤ 9a²/a²

( a² will get canceled since its common )

Thus, the ratio becomes,

➭ 9 : 1 = Area square with tripled length : Area of square

Thus, the area will increase by 9 times, and not 3.

Hence, Ashley's assumptions are wrong.
