Answer:
Step-by-step explanation:
Hello,
Let's not a and b the two numbers.
<em>One number is seven less than a second number.</em>
(1) b = a - 7
<em>Five times the first is 2 more than 6 times the second. </em>
(2) 5a = 2 + 6b
(2)+5*(1) gives
5a + 5b = 2 + 6b + 5a - 35
b = 35 - 2 = 33
a = 40
The value of the first number is
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
1) The area of the regular hexagon is approximately 11.256 unit²
2) The coordinates of the center is (2, 3)
3) The base length is approximately 2.08 units
4) The height of the hexagon is approximately 3.61 units
Step-by-step explanation:
1) The length, lₐ, of the apothem is given as follows;
Therefore, for the apothem having coordinates, (2, 3), and (3, 1.5), we have;
The length of half half of one side, S/2 = a × tan(30°) = √(3.25)/√3
The length of the base = 2 × √(3.25)/√3 ≈ 2.082 units
The perimeter, P = 6 × 2× √(3.25)/√3
The area, A = 1/2 × P × a = 1/2 × 6 × 2 × √(3.25)/√3 × √3.25 = (13·√3)/2
A = (13·√3)/2 unit²
The area of the regular hexagon, A = (13·√3)/2 unit² ≈ 11.256 unit²
2) The coordinates of the center = (2, 3)
3) The base, 'b', length by Pythagorean theorem is given as follows;
b = √(a² + (S/2)²) = √((√(3.25))² + (√(3.25)/√3)²) = √(3.25 + 3.25/3) = √(13/3) = (√39)/3
The base length, b = (√39)/3 units ≈ 2.08 units
4) The height of the hexagon, h = 2 × The length of the apothem, lₐ
The length, lₐ, of the apothem is given as follows;
Given the apothem coordinates, (2, 3), and (3, 1.5), we have;
The height of the hexagon, h = 2 × √3.25 units ≈ 3.61 units.
