A guy wire makes a 65° angle with the ground. walking out 37 feet further from the tower, the angle of elevation to the top of t
kicyunya [14]

Let's call the height of the tower h and the distance from the 65 degree angle to the base of the tower d.

We get two equations:

\tan 65^\circ = \dfrac h d

\tan 39^\circ = \dfrac{h}{d+37}

h = d \tan 65^\circ = (d+37) \tan 39^\circ

d(\tan 65 - \tan 39) = 37 \tan 39

d = \dfrac{37 \tan 39}{\tan 65 - \tan 39}

h = d \tan 65 = \dfrac{37 \tan 39 \tan 65}{\tan 65 - \tan 39}

h \approx 48.1 \textrm{ feet}

Answer: 48

The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders
irina1246 [14]

Using the data presented in the problem, you are asked to predict the probability that future customers will cancel their preorders. To find the probability, you have to divide the number of people who cancelled their preorders by the total number of people who preordered.

35 people / 140 people = .25 or 25% probability that the future customers will cancel their preorders.

bearhunter [10]

Answer:

w=10

Step-by-step explanation:

8.25+1/4w=10.75

8.25+0.25w=10.75

0.25w=10.75-8.25

0.25w=2.5

w=10
