Pi * r ^ 2 that’s house help you out with what you need hunn
Answer:
40%
Step-by-step explanation:
20 out of 50 simplifies to 2 out of 5 which is equivalent to 4 out of 10 which is also 40 out of 100 which is 40%.
So for QC to be a perpendicular bisector, it needs to make BC=CD lets label BC as X. BC+CD=BD. Because BC=CD, X+X=BD or 2X=24. Thus X=12. Thus BC=12. Now PB is a perpendicular bisector of AC so PB makes a right angle with AC at point B. PC=13(given) so because we have a right triangle, we can use the hypotenuse theorem so PC^2=BC^2+PB^2 or 13^2=12^2+PB^2 so 25=PB^2 so PB=5
Hope this helps!
Answer:
Step-by-step explanation:
Begin by multiplying both sides by 2
2*A = 2*(b1 + b2) * h/2 Cancel the 2s
2A = (b1 + b2 ) * h Divide both sides by (b1 + b2)
2A/(b1 + b2) = (b1 + b2)*h / (b1+b2) Cancel B1 + b2
2A/(b1 + b2) = h
15.050 < 15.500
notice that 500 is more than 50... so hope this helps a little bit !!!
