Answer:
They are equal
Step-by-step explanation:
All the sides are equal, because you use the pythagoreon theorem to find out that all the sides are equal.
2. WXZ=YXZ
3. Reflexive property of equality
(if they are angles)-
4. WXZ=YXZ ~~Reason- Congruent angles have equal number of degrees
(if they are triangles-more likely judging by the problem)-
4. Triangle WXZ=YXZ ~ Reason- SAS Congruence Postulate
Answer:
$23.88
Step-by-step explanation:
Represent the original price by p.
The sale price is (100% - 60%), or 40%, of p:
$9.55 = 0.40p
Dividing both sides by 0.40 results in:
p = $23.88 (rounded up from $23.875).
Answer:
Step-by-step explanation:
If a boat has the speed = 15 miles per hour
Let the speed of the river = v miles per hour
If the boat is moving down stream, that means boat is traveling with the stream of the river.
So the speed of the boat downstream = (15 + v) miles per hour
Since, speed of the river stream is added with the speed of the boat, it will reach the destination earlier than the expectation.
