Answer:

The boats will meet in 3.33 hours.

A || b what’s the value of X?
Anna007 [38]
<h3><u>Answer:</u></h3>
  • The value of x is 17.
<h3><u>Step-by-step explanation:</u></h3>

<u>We know that the lines are parallel because it is given that:</u>

  • a ∥ b

<u>Now, let's form an equation.</u>

  • => 2x + 5 + 8x + 5 = 180

<u>Let's solve!</u>

  • => 10x + 10 = 180
  • => 10x = 170
  • => x = 17

Hence, the value of x is 17.

Set A contains three different positive odd integers and two different positive even integers; set B contains two different posi
Lostsunrise [7]

Answer:

\frac{2}{5}*\frac{3}{5} +\frac{2}{5}*\frac{2}{5}+\frac{3}{5} *\frac{3}{5}  = \frac{19}{25}

Step-by-step explanation:

We must remember that in order to get one even number we need to multiply one even number times one odd number or two even numbers. So, the first term tells the probability of having an even number from A and an even number from B, the next would be even from A and odd from B and the last one tells the likelihood of having odd from A and even from B
