First step is to turn 5% into a decimal -- 0.05
Next, find out what 5% of $32.55 is by multiplying
0.05 x 32.55
= 1.6275
Round to the nearest cent
= $1.63
This is the amount of tax $32.55
If we want to know what it the book costs before tax we simply take the tax off.
$32.55 - $1.63
= $30.92
Answer:
This isn't a question, you just said some things. What does "what si the scale of diagram b" mean? I'd really like to help but this is confusing
Step-by-step explanation:
Answer:
x=110, y=50
Step-by-step explanation:
Draw a line perpendicular to the base CD from point A. The point of intersection is E. Angle AED=90 degrees. This is a right angle triangle. A triangle has a total angle of 180 degrees. Angle DAE is then 180-(90+70) = 20. The bases of a trapezoid are parallel to each other, making angle EAB a right angle. Add 90 + 20, and you'll get 110 degrees. This is the value of x.
Draw another line perpendicular to the base CD, this time from point B. The point of intersection is F. Angle ABF is 90 degrees. Angle FBC is 130-90=40. Angle BFC is also 90 degrees. You once again find the difference of the numbers from 180. 180-(40+90)=180-130=50. y=50 degrees.
In order to find the are you have to multiply length x width.
In order to find the perimeter you have to add up all the sides together.
