If it takes a ball to roll 12 meters per sec, and asks how far it will roll for 3 seconds you would multiply 12 and 3 getting 36.

The ball will roll 36 meters for 3 seconds

The ball will travel 36 meters because 12 times 3 = 36

Choose all options that apply.

Hey there!

Guide ⬇️

• Cup: is a cooking measurement for volume, it very much common in sizes & cooking things.

• Tablespoon: a abundant (huge) sized spoon that’s used for serving.

• Liter: is the limitation of volume that is held which is balanced (equal to) to ONE cubic decimeter.

• Fluid ounce: is basically unit space that is held at 1/16th of a US pint.

Based on that information the one that seems closer to the RIGHT answer is:

[Option A. Cup]

[Option B Tablespoon]

[Option D. Fluid Ounce]

Random fact:

• [1 (US) CUP] is approximately [8 (US) OUNCE]

• [1 (US) TABLESPOON] is approximately [1/2 (or 0.5)(US) US OUNCE)

• [1 FLUID OUNCE] is approximately [28.35 GRAM]

Good luck on your assignment and enjoy your day!

Consider solving the equation for x.

Anna [14]

So let's simplify the equation first.

9x + 12 - 5 = ax + b
9x + 7 = ax + b
9x - ax - b = 7

Alright now plug in the numbers for each option.
I don't feel like doing all of them but I did A (one solution) and B (no solution because the two 9x's cancel out).

What is a counterexample of the statement “all square roots are irrational”

skad [1K]

Rather than trying to guess and check, we can actually construct a counterexample to the statement.

So, what is an irrational number? The prefix "ir" means not, so we can say that an irrational number is something that's not a rational number, right? Since we know a rational number is a ratio between two integers, we can conclude an irrational number is a number that's not a ratio of two integers. So, an easy way to show that not all square roots are irrational would be to square a rational number then take the square root of it. Let's use three halves for our example:

$\sqrt{(\frac{3}{2})^2}=\\\sqrt{\frac{9}{4}}=\\\frac{3}{2}$

So clearly 9/4 is a counterexample to the statement. We can also say something stronger: All squared rational numbers are not irrational number when rooted. How would we prove this? Well, let $\frac{a}{b}$ be a rational number. That would mean, $\frac{a^2}{b^2}$ , would be a/b squared. Taking the square root of it yields:

$\sqrt{\frac{a^2}{b^2}}}=\\ \frac{\sqrt{a^2}}{\sqrt{b^2}}=\\ \frac{a}{b}$

So our stronger statement is proven, and we know that the original claim is decisively false.
