Answer:
10) It increased by appoxamately 17%.
11) 255 decreased by 20%
12) 15 increased by 
%
13) $9,450
14) $149.8
15) $238.5
Step-by-step explanation:
10) 170 is greater than 150 by 25. 25 is 
% of 150, so it increased by appoxamately 17%.
11) 225 is decreased by 45. 45 is 20% of 100, so 255 decreased by 20%
12) 15 is increased by 10. 10 is of 15, so 15 increased by %
13) 5% of 9,000 is 450. 450 + 9,000 is $9,450
14) 7% of 140 is is 9.8. 140 + 9.8 = $149.8
15) 6% of 225 is 13.5. 225 + 13.5 = $238.5
Answer:
200√3
Step-by-step explanation:
The triangle given here is a special right triangle, one with angles measuring 30-60-90 degrees. The rule for triangles like these are that the side opposite the 30° angle can be considered x, and the side opposite the 60° angle is x√3, while the hypotenuse, or side opposite the right angle, is 2x. All we need to know here are the two legs to find the area.
Since b is opposite the 30° angle, it is x, while side RS is opposite the 60° angle, meaning it is equal to x√3, meaning that the area of the triangle is 1/2*x*x√3. We can substitute in 20 for x, making our area 1/2*20*20√3. Multiplying we get 10*20√3, or 200√3.
Easy, use these two formulas, to find Markdown:
Markdown=Original-New
and
Markdown%=
So, plug in what you know.
Markdown= $30-$20.10
M=$9.90
Now, Markdown%
Markdown%=
M%=0.33*100
M%=33
Thus, there was a 33% markdown.
Answer:
1/3 is the y-intercept of the function
E because 8*8=64 so 8/49*8/49 = 64/49
