42\% \ of \ x = 29.3 \\\\ \frac{42}{100}*x= 29.3 \\\\ \frac{21}{50}*x=29.3 \\\\ x=\frac{50*29.3}{21} \\\\ x=\frac{1465}{21} \\\\ \boxed{x=69.76 \to \boxed{\boxed{70}}}

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.

I think its perimeter so you do 10x2=20 and 20x2=40 and add 20+40 to get 60 so the answer is 60 cause it says "fencing" which is the outer border

therefore answer is 60 feet

Answer:

<u> The total amount = $175</u>

Step-by-step explanation:

Let the total amount in his bank account = x

Nick decided to take 2/5 of the money in his bank account and donate it to a local charity

So, he donates with \frac{2}{5} x

If nick donated $70 to a local charity

so, \frac{2}{5} x = 70

solve for x

∴ x = 5*70/2 = 350/2 = $175

<u>So, The total amount = $175</u>
