8x - 5 ≥ 27
8x ≥ 32 <-- Add 5 to both sides
x ≥ 4 <-- Divide both sides by 8
So, to be in solution set, x has to be greater or equal to 4.
In interval notation: [4, ∞)
In a set builder notation: {x | x ∈ R, x ≥ 4}
Answer: d
Step-by-step explanation:
The graph is increasing, so the base must be more than 1.
Also, the y-intercept is 2.
This leaves d.
The arc length is the measure of the distance along the curved line making up the arc<span>. It is longer than the straight line distance between its endpoints. To calculate this we simply multiply the angle to the circumference of the circle. It is expressed as:
Arc length = 2</span>πr(angle / 360)
Arc length = 2πr(50 / 360)
Arc length = 5πr / 18
Just multiply the radius then you're good. Hope this helps. Have a nice day.
Answer:
226
Step-by-step explanation:
To find the percentage of a given value, firstly convert to a decimal by dividing by 100:
82 ÷ 100 = 0.82
Now, multiply this decimal by the number of tickets:
275 x 0.82 = 225.5
Because you can't sell half a ticket, round up.
This means the total of tickets they need to sell is 226.
Hope this helps!
