Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

8x - 7 + x + 7 + 2x + 15 = 180 , that is

11x + 15 = 180 ( subtract 15 from both sides )

11x = 165 ( divide both sides by 11 )

x = 15

Alice is thinking of a number n that she wants her sister to guess. Her first clue is that two less than six times her number is
Alik [6]

Answer:

10 < 6n -2 ≤ 34

n= {3, 4, 5, 6}

Step-by-step explanation:

number

⇒ n

two less than six times the number

⇒ 6n -2

it is between ten and thirty-four (inclusive)

⇒ 10 < 6n -2 ≤ 34

we can solve it as:

  • 10 < 6n -2 ≤ 34     ⇒ add 2 to all sides
  • 12 < 6n ≤ 36          ⇒ divide by 6 all sides
  • 2 < n  ≤ 6
  • n= (2, 6]

or

  • n= {3, 4, 5, 6}

If the diameter of a hockey rink is 250 ft what is the surface area of the sphere?
Lady bird [3.3K]

Answer:

62,500 pi

Step-by-step explanation:

diameter = radius + radius

d = 2r

r = d/2

A = 4pi r^2

= 4 pi (d/2)^2

= 4pi d^2/4

= 4pi* 250^2/4

= 4pi * 62,500/4

= 4pi * 15625

= 62,500 pi
