Yes, a plane is a one dimensional figure
Answer:
$9.47
Step-by-step explanation:
Add all her purchases together
97.62 + 22.95 + 14.78 = 135.35
The total tax is 6.5% sales tax, and 0.5% country tax
6.5% + 0.5% = 7%
Multiply the total amount spent by the total tax
Remembering that you need to convert the 7% into an integer, by simply diving by 100 first
135.35 * 0.07 = 9.47
Set up a proportion.
The total side of the “top” line is 8 + 10 = 18. The total side of the “bottom” line is 45. This makes the ratio 18/45.
Now we are trying to find the “larger” bottom segment, let it be x. Because the lines are parallel, the ratio of the “larger” top and bottom segments is equal to the ratio of the whole top and bottom lines.
So 18/45 = 10/x
Reduce 2/5 = 10/x
Cross multiply 2x = 50
Solve x = 25
360 degrees is the whole circumference.
300 degrees is 300/360 of the circumference.
The circumference: pi*r*2 = 4*pi = approximately 12.566.
300/360*12.566=10.472 = answer
