Answer:
Angles on a straight line add up to 180°
Therefore, the interior angle D of the triangle = 180 - 150 = 30°
Draw a horizontal line of 8 cm - label DE.
Measure an angle of 30° from point D and draw a line.
Measure an angle of 90° from point E and draw a line.
These 2 lines will intersect at point F.
Erase the part of the lines that extend past the point of intersection.
Answer: 6x-4
Step-by-step explanation: The number 6 is multiplied by another variable so it would be written as 6x and then 4 is less than whatever 6x is so it would be 6x-4.
Answer:
3x + 50 ≥ 100
At least 17 sales
Step-by-step explanation:
To solve this inequality you have to subtract 50 from both sides so 50 - 50 cancels out and 100 - 50 = 50
So now you have 3x ≥ 50, what you'll do is divided both by 3 so 3 ÷ 3 cancels out and 50 ÷ 3 = 16.6666 (repeating number)
x ≥ 16.6666 (repeating number) but since he cant make .6 of a sale you have to round that up to 17 sales.
So, the salesperson needs to make at least 17 sales to be paid at least 100
Step-by-step explanation:
Don't let the variables scare you. they are just an unknown value, that we can call anything we want. So, we can say y=6-0.6x. If you want an easier equation, just use communitive property to change it to
Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t
You can see a = 8,000
As the fish population starts at 8,000
