Answer:

x = 3/5

Step-by-step explanation:

After substituting each option into the equation, we find that the only option that makes the equation true is x=3/5, since 4/5 - 3/5 = 1/5.

Stels [109]

Answer:

A. 1/4

Step-by-step explanation:

We know that before the 1st bounce, the height of the ball is 512 inches.

Say the fraction is x.

Then, after the first bounce, the height of the ball is 512 * x = 512x.

After the second bounce, the height is now x * 512x = 512x².

By similar reasoning, the height after the third bounce is 512x³ and after the fourth bounce, it is $512x^4$ .

We also know that after the fourth bounce, the height is 2 inches. So, set 2 equal to $512x^4$ :

2 = $512x^4$

Divide both sides by 512:

$x^4=2/512$ $x^4=2/512=1/256$

Take the fourth root of both sides:

$x=\sqrt[4]{1/256} =1/4$

Hence, the answer is A.

which set of numbers could represent the lengths of the sides od a right triangle 16 32 36 3 4 5 8 12 16 9 10 11

pantera1 [17]

Answer:

3 , 4 , 5 can formed right triangle

Step-by-step explanation:

In any triangle if the sum of the squares of the smallest two sides equals the square of the third side, then the triangle is right triangle

∵ 16² + 32² = 1280

∵ 36² = 1296 ≠ 1280 ⇒ Not right Δ

∵ 3² + 4² = 25

∵ 5² = 25 ⇒ right Δ

∵ 8² + 12² = 208

∵ 16² = 256 ≠ 208 ⇒ Not right Δ

∵ 9² + 10² = 181

∵ 11² = 121 ≠ 181 ⇒ Not right Δ
