A developer is building a scale model of the city. From the roof of an apartment complex, the developer points two lasers at the taller office building across the street. The first laser points to the base of the building and the second laser points to the top of the building. The first laser beam has an angle of depression of 36° and is 155.7 feet long. The second has an angle of elevation of 32° and is 148.6 feet long. How tall is the office building? How far apart are the apartment complex and the office building? Round your answers to the nearest foot.
Answer:
a. 170 ft b. 126 ft
Step-by-step explanation:
a. How tall is the office building?
The two laser lights with the length of the taller office building, L form a triangle with sides 155.7 feet, 148.6 feet and L with angle 36° + 32° = 68° facing the taller office building.
We use the cosine rule to find the length of taller office building.
So, L² = 155.7² + 148.6² - 2(155.7)(148.6)cos68°
L² = 24242.49 + 22081.96 - 46,274.04(0.3746)
L² = 46324.45 - 17334.56
L² = 28989.89
L = √28989.89
L = 170.26 ft
L ≅ 170 ft
b. How far apart are the apartment complex and the office building?
Using one of the lights, the distance between the buildings, d, the laser light(being the hypotenuse side) and the building (being the opposite side)form a right angled triangle.
So, using the 155.7 feet light at 36 angle,
cos36 = d/155.7
d = 155.7cos36
d = 155.7(0.8090)
d = 125.96 ft
d ≅ 126 ft
What is the value of z?
No links please!!
9514 1404 393
Answer:
z = 14.4
Step-by-step explanation:
The angle bisector divides the sides proportionally.
z/12 = 6/5 . . . . . . . . . write a proportion*
z = 12(6/5) = 72/5 . . . . . multiply by 12
z = 14.4
_____
* We consider the proportion easier to solve if the unknown is in the numerator. Then the solution is found by multiplying the equation by that denominator.

Answer / Explaination:
An equation that represents this problem is b = 52h.
A linear model that represents this equation would look as such (see below)
To predict how many boxes would be produced after an 8 hour shift, you can look at the graph (see additional attatchement) or substitute 8 in for h in the equation.
b = 52(8)
b = 416

Laura is bowling 5 games. Her first 4 scores were 103, 143, 101, and 110.
To end up with an average score of at least 126.8, what is the lowest score Laura will need in the fifth
game?
Answer:
The least 5th score is 177
Step-by-step explanation:
Given
[tex]First\ 4: 103, 143, 101, 110.[/tex]
[tex]Average = 126.8[/tex]
Required
The least 5th score
Represent the 5th score with x.
The average is calculated as:
[tex]Average = \frac{\sum x}{n}[/tex]
So, we have:
[tex]126.8 = \frac{103 + 143 + 101 + 110 + x}{5}[/tex]
[tex]126.8 = \frac{457 + x}{5}[/tex]
Multiply both sides by 5
[tex]634= 457 + x[/tex]
Solve for x
[tex]x = 634- 457[/tex]
[tex]x = 177[/tex]
x+y=11
x-y=-5

Answer:
[tex]x=3[/tex]
[tex]y=8[/tex]
Step-by-step explanation:
The process of elimination is a method of solving a system of equations. This process includes manipulating a system of equations such that one variable present in both equations has its coefficients as additive inverses. When one adds the equation, this variable will cancel, one can solve for the other variable using inverse operations, and then back solve for the eliminated variable.
[tex]\left \{ {{x+y=11} \atop {x-y=-5}} \right.[/tex]
As one can see, the coefficients of variable (y) are already additive inverses of each other (1), (-1), therefore, one can add the systems right away.
[tex]\left \{ {{x+y=11} \atop {x-y=-5}} \right.[/tex]
[tex](x)+(y)+(x)+(-y)=(11)+(-5)[/tex]
Simplify,
[tex]2x=6[/tex]
Inverse operations,
[tex]x=3[/tex]
Backsolve for (y), substitute the value of (x) into one of the original equations to find the value of (y),
[tex]x+y=11\\[/tex]
Substitute,
[tex](3)+y=11[/tex]
Inverse operations,
[tex]y=8[/tex]

The area of a triangle is 24 square inches. What is the height of the triangle if the base length is 4 inches? (5 points) 6 inches 8 inches 12 inches 20 inches
9514 1404 393
Answer:
12 inches
Step-by-step explanation:
The area is given by the formula ...
A = 1/2bh
Fill in the given values and solve for the height.
24 in² = 1/2(4 in)h
h = (24 in²)/(2 in) = 12 in
The height of the triangle is 12 inches.
Answer:
12 inches
Step-by-step explanation:
Area = [tex]\frac{1}{2}bh[/tex]
24 = [tex]\frac{1}{2} * 4 * h[/tex]
24 = 2h
h = 12 inches

a cruise ship heads due west from a port 3 miles directly south of San Francisco. If the ship is travelling at a constant rate of 17 mph, how fast is the distance between the ship and san francisco changing 1 hour after leaving port
Answer:
16.7
Step-by-step explanation:
speed is constant at 17 mph
Distance covered after one hour = 17 miles
Distance between port and San Francisco = 3 miles
Speed at which distance changes 1 hour after leaving port :
r² = 17² - 3²
r² = 289 - 9
r = √280
r = 16.733
= 16.7 (nearest tenth )

A rectangle has a width of 6 and a length of 2x+8. The area is 108 squared, what is the value of x?
Answer:
x = 5
Step-by-step explanation:
108 = 6(2x + 8)
108/6 = 18
18 = 2x + 8
18 - 8 = 10
10 = 2x
10/2 = 5
5 = x
A young entrepreneur wants to set up a lemonade stand at a busy intersection. Customers arrive at a rate of 38 customers per hour according to a Poisson distribution. Customers will be served at the average rate of 58 customers per hour with exponential service times. What is the average utilization rate (%) of the entrepreneur
Answer:
65.5%
Step-by-step explanation:
Arrival rate, λ = average number of customers per hour = 38
Servive rate, μ = number of customers attended to per hour = 58
Utilization factor, ρ = λ / μ
ρ = 38 / 58
ρ = 0.6551724
Utilization rate (%) = 0.6551724 * 100% = 65.5%
