On the first day of ticket sales the school sold 1 senior citizen ticket and 5 child tickets for a total of $60. The school took
Stells [14]

Answer:

Step-by-step explanation:

Let's start off with the first equation

5x + y = 60

We need to find what X and Y are.

Let's try subtracting a few numbers from 60.

Let's do 60 - 55 = 5

11x5 = 55

11 = Children Ticket Cost

5 = Seniors Ticket Cost

Without them being the same price!

So using the numbers we found, we can now solve the second one

14x5 = 70

11x11 = 121

70 + 121 = 191

There we go!

Hope this helped! Please give brainiest if you can :)

Solve this quadratic equation.<br><br> 6x2 - 2x = 7
rjkz [21]

Answer:

x₁ = (1 + √43)/6

x₂ = (1 - √43)/6

Step-by-step explanation:

6x² - 2x = 7

6x² - 2x - 7 = 0

Formula

ax² + bx + c = 0

a = 6 ; b = - 2 ; c = - 7

x₁/₂ = [-b ± √(b²- 4ac)]/2a

x₁/₂ = (2 ± √4 + 4×6×-7)/12

x₁/₂ = (2 ± √172)/12

x₁/₂ = (2 ± 2√43)/12

x₁/₂ = 2(1 ± √43)/12

x₁/₂ = (1 ± √43)/6

x₁ = (1 + √43)/6

x₂ = (1 - √43)/6

Please help me i will give u brainliest
vivado [14]

Answer:

A ≈ 9.0 ft²

Step-by-step explanation:

70° = 7π/18 radians

Area of the arc section

A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²

As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°

law of sines 8 / sin55 = L / sin 70  L = 9.17722

so the triangle height  = √(8² - (9.17722/2)²) = 6.55321

Area of triangle ½(6.55321)(9.17722) = 30.07016

Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²
