Answer:
14.
15.
Step-by-step explanation:
Solving (14):
First, we solve for x.
Since sides , then
This is so because the theorem of ASA (Angle-Side-Angle)
So, we have:
Collect Like Terms
Divide both sides by 3
Solving for m<B, m<C and m<D.
We simply substitute 11 for x in their respective expressions.
Solving (15):
First, we solve for x.
Since , then
This is so because the theorem of SAS (Side-Angle-Side)
So, we have:
Collect Like Terms
Divide both sides by 2
Solving for WX, WY and XY
We simply substitute 4 for x in their respective expressions.

Answer:
(1/120 mile/min)(60 min/h)(3 h)
1.5 mile
the increase in depth after 3 hours
Step-by-step explanation:
The rate is given in terms of miles per minute. To find the elevation after 3 hours, we need a conversion from minutes to hours. One possible product is ...
(1/120 mile/min)(60 min/h)(3 h)
The value of this product is ...
(1·60·3)/(120·1·1) mile = 1.5 mile
The value represents the increase in depth after 3 hours.
The product of three rational numbers is 1.5, which represents the change in the submarine's elevation after 3 hours.
To represent the change in the submarine's elevation after 3 hours, we need to find the product of the descent rate per minute and the total number of minutes in 3 hours. The descent rate per minute is 1/120 mile, and there are 60 minutes in an hour. So, the product is:
(1/120) * (60 * 3)
Simplifying the expression:
(1/120) * 180 = 1.5
The value of the product, 1.5, represents the total change in the submarine's elevation after 3 hours. Since the submarine is descending, the elevation decreases by 1.5 miles.

The probability that the commuter has to stop at least three times is at least 5.55%.
Since on her way to work, a commuter encounters four traffic signals, assuming that the distance between each of the four is sufficiently great that her probability of getting a green light at any intersection is independent of what happened at any previous intersection, and the first two lights are green for forty seconds of each minute; the last two, for thirty seconds of each minute, to determine what is the probability that the commuter has to stop at least three times the following calculation must be performed:
Therefore, the probability that the commuter has to stop at least three times is at least 5.55%.

Answer:
7 in 36 or 0.1944
Step-by-step explanation:
The probability of having to stop at least three times is the probability of getting 3 or 4 red lights.
For the first two lights, the probability of getting them red is 20 in 60 (1/3).
For the last two lights, the probability of getting them red is 30 in 60 (1/2).
The probability of all of them being red is:
The probability of three of them being red (3 red + 1 green) is:
Therefore, the probability of at least three red lights is:
The probability is 7 in 36 or 0.1944.
