<span>1) We are given that PA = PB, so PA ≅ PB by the definition of the radius.
</span>When you draw a perpendicular to a segment AB, you take the compass, point it at A and draw an arc of size AB, then you do the same pointing the compass on B. Point P will be one of the intersections of those two arcs. Therefore PA and PB correspond to the radii of the arcs, which were taken both equal to AB, therefore they are congruent.
2) We know that angles PCA and PCB are right angles by the definition of perpendicular.
Perpendicularity is the relation between two lines that meet at a right angle. Since we know that PC is perpendicular to AB by construction, ∠PCA and ∠PCB are right angles.
3) PC ≅ PC by the reflexive property congruence.
The reflexive property congruence states that any shape is congruent to itself.
4) So, triangle ACP is congruent to triangle BCP by HL, and AC ≅ BC by CPCTC (corresponding parts of congruent triangles are congruent).
CPCTC states that if two triangles are congruent, then all of the corresponding sides and angles are congruent. Since ΔACP ≡ ΔBCP, then the corresponding sides AC and BC are congruent.
5) Since PC is perpendicular to and bisects AB, P is on the perpendicular bisector of AB by the definition of the perpendicular bisector.
<span>The perpendicular bisector of a segment is a line that cuts the segment into two equal parts (bisector) and that forms with the segment a right angle (perpendicular). Any point on the perpendicular bisector has the same distance from the segment's extremities. PC has exactly the characteristics of a perpendicular bisector of AB. </span>
You would subtract 90% and 35% and get 55%. You subtract that by 20 and yiu will have 35% of the 90% mixture
Answer:
$14.5
Step-by-step explanation:
Given data
Cost for the visit=442.25 Rubles
exchange rate
3 USD= 91.5 Rubles
but 1 USD= 91.5/3
= 30.5
Therefore if 1 USD is 30.5 Rubles
Then xUSD is 442.25 Rubles
cross multiply
30.5x= 442.25
divide both sides by 30.5
x= 442.25/30.5
x=14.5USD
The cost of the attraction is $14.5
Answer:
$22843.75
Step-by-step explanation:
I'm assuming that $18.275 is $18,275
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 18275 × 0.05 × 5 = 4568.75
I = $ 4,568.75
The simple interest accumulated
on a principal of $ 18,275.00
at a rate of 5% per year
for 5 years is $ 4,568.75.
