An olympic-size swimming pool is a rectangle that measures 50 meters in length and 25 meters in width.

Licemer1 [7]

Answer:

10x5 (LxW)

Step-by-step explanation:

1 centimeter in your drawing should equal to 5 meters of the pool.

The length is 50, so 50/5 (5 is in meters, and it is equal to 1 centimeter) equals: 10

The width which is 25 in meters, would be equal to 5 centimeters in your drawing

I don't know if i made my explanation clear but hopefully the answer helped.

A speed boat is traveling at 100km/hr. how many hours will it take for the boat to cover a distance of 115?

Oliga [24]

Answer

1.15 hours

Step-by-step explanation:

Assuming 115 is 115 km then you just move the decimal point twice and get 1.15!

For example - (Starting number) 115. (Moving decimal point) 115. -> 11.5 -> 1.15

Answer:

I answered the questions but that formatting is very confusing and discourages anyone for trying to answer.

The last question is confusing. If I got it wrong, tell me. I will try to answer in the comment section then.

Step-by-step explanation:

Kayson is looking at two buildings, building A and building B, at an angle of elevation of 73°. Building A is 30 feet away, and building B is 35 feet away. Which building is taller and by approximately how many feet?

$\text{tan}\theta=\frac{h_{A}}{30} \Rightarrow h_{A}=\text{tan}73\º \cdot 30 \Rightarrow h_{A}\approx 98.12 \text{ feet}$

$\text{tan}\theta=\frac{h_{B}}{35} \Rightarrow h_{B}=\text{tan}73\º \cdot 35 \Rightarrow h_{B}\approx 114.47 \text{ feet}$

$\text{Difference} \approx 16.35$

Building B is around 16.35 feet taller than building A.

A Look at the figure below: an image of a right triangle is shown with an angle labeled y If sin y° = a divided by 6 and tan y° = a divided by b, what is the value of cos y°?

$\text{sin}(y)=\frac{a}{6}$

$\text{tan}(y)=\frac{a}{b}$

a is the opposite side; 6 is the hypotenuse; b is the adjacent side.

Therefore,

$\text{cos}(y)=\frac{b}{6}$

If sin f° = eight ninths and the measure of segment YW is 24 units, what is the measure of segment YX? triangle XYW in which angle W is a right angle, angle X measure f degrees, and angle Y measures d degrees.

This seems a bit confusing. The angles don't match. We have $90\º+62\º +21\º \approx 173\º$

$\text{sin}(f)=0.888...$

$f \approx 62\º$

YX is the hypotenuse of the right triangle.

$\text{cos}(21\º)=\frac{24}{YX}$

$YX \approx 25.7$

Considering $f \approx 69\º$

$\text{sin}(69\º)\approx\frac{24}{YX}$

$YX \approx 25.7$
