The two white triangles have areas of 1/2 x 3 x 10 and 1/2 x 6 x 10 = 15 + 30 = 45 cm^2
The shaded area will be 10 x 10 - 45 = 55 cm^2
The percentage shaded = 55 / 100 x 100% = 55%

Really need help ???
Westkost [7]

Answer:

$105 (Make sure to read the explanation)

Step-by-step explanation:

120.45 + 95.75 + 105.32 + 140.25 + 89.68 + 101.32 = 652.77

652.77 ÷ 6 = 108.795

I think the mean as her budget is a tiny weny too high so I think $105 is a good enough budget. Feel free to change it.

The Hogwarts Express train has reduced its one-way fare from 360 galleons to just 270 galleons. What is the percentage decrease
Likurg_2 [28]
<h3>Answer:   25% decrease</h3>

=======================================================

Work Shown:

A = old value = 360

B = new value = 270

C = percent change

C = (B-A)/A

C = (270-360)/360

C = -90/360

C = -0.25

C = -25%

The negative C value indicates we have a percent decrease.

Note how 25% of 360 = 0.25*360 = 90, meaning that the price has dropped by 90 galleons. And also note that 360-270 = 90 is that same figure of 90. This helps confirm the answer.
