<span>you can only use the perpendicular bisector to determine a midpoint.</span>
the coupon is 35% off, therefore, she actually paid 65%
0.65(128.25) = 83.36 (what she paid without tax)
now we add the sales tax of 4%
83.36 (1.04) = 86.69 <== total cost
Answer:
See the explanation
Step-by-step explanation:
When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100
example
Numerator >Denominator
=4/2*100
=2*100
=200%
Numerator <Denominator
=2/4*100
=0/5*100
=50%
Let the speed of first car be x mph
the speed of the second one is (x+3) mph
Relative speed=x+x+3=(2x+3) mph
but
time=distance/speed
thus
3=(261)/(2x+3)
solving for x we get:
3(2x+3)=261
6x+9=261
6x=261-9
6x=252
hence:
x=42 mph
Thus the average speed of first car is 42 mph
Average speed of the second car is (42+3)=45 mph

Answer:
(b) ... confirm ∠C≅∠E
Step-by-step explanation:
The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE by AA similarity. That means you want to show any two of the three ...
For this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.
Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.
The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.
