Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
A variable with a fraction exponent can be rewritten using a radical.
The equations would be A. radical equation
A) x + .07x = 45.50
X is the price of the toy boat, •07x adds the tax for a total paid of $45.50
The car was towed 44miles (162 - 30 = 132. 132 divided by 3 = 44)
The result is <span>B. 1638.</span>
To calculate this, we will use both an addition and a multiplication rule. The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. <span>The multiplication rule calculates the probability that both of two events will occur.
First, there are two possibilities for winning exactly one match:
1. To win the first match and lose the second one.
2. To lose the first match and win the second one.
9% = 0.09 is the probability of winning. The probability of losing is 1-0.09 = 0.91. To calculate the probability of winning </span><span>the first match and losing the second one and vice versa, we will use the multiplication rule:
</span>1. 0.09 × 0.91 = 0.0819
2. 0.91 × 0.09 = 0.0819
We want to either one of these events to happen, so using the addition rule, we have:
0.0819 + 0.0819 = 0.1638
In 10,000 matches:
0.1638 × 10,000 = 1,638
