Answer:
22/90.
Step-by-step explanation:
0.24444... * 100 = 24.4444...
0.244444.. * 10 = 2.44444....
Subtract:
0.244444.. * 90 = 22
So the required fraction is 22/90.
Answer:
all options are correct.
Step-by-step explanation:
The correct options among all the options are:
- <em>Ancient mathematicians used trigonometry to find angles of triangles.</em>
Trigonometry is used to find the size of a missing side or angle in a right- angled triangle using the sine, cosine or tangent ratios.
- <em>Ancient mathematicians used trigonometry to track the position of the sun.</em>
It is also used in oceanography in calculating the height of tides in oceans.
- <em>Tangent was the first trigonometric relationship used by mathematicians.</em>
The three main functions in trigonometry are Sine, Cosine and Tangent.The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.
- <em>Cosine was the first trigonometric relationship used by mathematicians.
</em>
- <em>Sine was the first trigonometric relationship used by mathematicians.</em>
Answer:
The answer to your question is Area = 37500 ft²
Step-by-step explanation:
Data
lawn 1 lawn 2
width = 550 ft width = 250 ft
Area = 181500 ft² Area = ?
Process
1.- Find the length of lawn 1
Area = length x width
-solve for length
length = Area/width
-Substitution
length = 181 500 ft²/ 550
-result
length = 330 ft
2.- Find the length of lawn 1 using ratios and proportions
550 : 330 :: 250 : x
x = (250 x 330) / 550
x = 150 ft
3.- Find the area of lawn 2
-Substitution
Area = 250 x 150
-Result
Area = 37500 ft²
