From the top of the tower 30 m height a man is observing the base of a tree at an angle of depression measuring 30 degree. Find the distance between the tree and the tower.
Please show your work
Answers
Answer:
30√3 m ≈ 52 m
Step-by-step explanation:
The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. The long leg of the triangle is √3 times 30 m, or about 51.96 m.
The distance between the tree and the tower is about 30√3 m ≈ 52 m.
__
If you haven't memorized the ratios of this special triangle, you can use the relation ...
Tan = Opposite/Adjacent
tan(30°) = 30/d
d = 30/tan(30°) = 30√3 = 51.96 . . . . same as above

A city receives 2 inches of snowfall every 3 hours. Write and graph a function that describes the relationship. How long does it take to receive 1 foot of snow? Use x for the independent variable and y for the dependent variable.
Answers
Answer:
To receive 1 foot of snow it will take about 18 hours.
Step-by-step explanation:
Given that a city receives 2 inches of snowfall every 3 hours, to write and graph a function that describes the relationship and determine how long does it take to receive 1 foot of snow, the following calculation must be performed:
1 foot = 12 inches
(12/2) x 3 = X
6 x 3 = X
18 = X
Thus, to receive 1 foot of snow it will take about 18 hours.

What is the slope of line that passes through the points (-3,8) and (1,32)?
Answers
Answer:
6
Step-by-step explanation:
use the formula of slopes
[tex] = \frac{y2 - y1}{x2 - x1} \\ = \frac{32 - 8}{1 - ( - 3)} \\ = \frac{24}{4} \\ = 6[/tex]
Answer:
[tex]\frac{31 }{11 }[/tex]
Step-by-step explanation:
The formula to solve this is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. In this case, the expression would be: [tex]\frac{32 -1 }{8 -(-3) }[/tex] or [tex]\frac{32 -1 }{8 +3 }[/tex]. This is also [tex]\frac{31 }{11 }[/tex].
Hope it helps and is correct!

they could solve the riddle, it would reveal how old she was. Her riddle stated: "The
product of my age and five, then decreased by twenty and finally increased by my
age times negative three is fifty." How old was Larry's math teacher? Hint: Write the
equation first, then solve to find the missing part.
Answers
Answer:
age is 35
Step-by-step explanation:

Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning. The lcm of two numbers is the product of the two number discuss your conclusion with a partner
Answers
Answer:
Sometimes
Step-by-step explanation:
Example 1:
Take two numbers as [tex]7,8[/tex]
LCM of [tex]7,8=7(8)=56[/tex]
In this case, the lcm of two numbers is equal to the product of the two numbers.
Example 2:
Take two numbers as [tex]6,3[/tex]
[tex]6=3(2)[/tex]
So,
LCM of [tex]6,3=3(2)=6[/tex]
In this case, the lcm of two numbers is not equal to the product of the two numbers.
Therefore,
Sometimes, the lcm of two numbers is equal to the product of the two numbers.

Write a paragraph explaining why consumer goods packaged in cube-shaped boxes would use less packaging material than rectangular boxes containing the same product volumes. Provide an example, including sketches of the boxes and their dimensions, to substantiate your explanation. Why aren’t more products in cube-shaped boxes?
Answers
Answer:
Students review how to determine the surface area and volume of a rectangular prism, that all dimensions are equal in cubes so the volume of cubes are the length of any side raised to the third power, or cubed. This prepares them for two associated activities. First, students find the volumes and surface areas of rectangular boxes such as cereal boxes and then figure out how to convert their boxes into a new, cubical boxes having the same volume as the original. As they construct the new, cube-shaped boxes from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package items. Students consider why consumer goods are generally not packaged in cube-shaped boxes, even though this would require fewer materials and ultimately, less waste. Then, to display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.
