Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2
Answer: 150 coins
Step-by-step explanation: let the number of captain Sparrow and the crew = c
The number of gold = g
This mean each person will get g/c
If there were four fewer pirates, then each person would get 10 more coins means
g/(c - 4) = g/ c+ 10
cg = (c-4)(g+10c) ....... (1)
However, if there were 50 fewer coins, then each person would get 5 fewer coins.
(g - 50)/c = g/c - 5
g - 50 = g - 5c
5c = 50
c = 10
Substitute c in equation 1
cg = (c-4)(g+10c) ....... (1)
10g = (10 - 4)(g + 10×10)
10g = 6× (g + 100)
10g = 6g + 600
4g = 600
g = 150 gold coin.
Therefore they dig up 150 gold coin

==================================================
Explanation:
When applying any kind of reflections, the parallel sides will stay parallel. Check out the diagram below for an example of this.
So PQ stays parallel to RS. Also, QR stays parallel to PS.
The statement "PQ is parallel to PS" is incorrect because the two segments intersect at point P. This letter "P" is found in "PQ" and "PS" to show the common point of intersection. Parallel lines never intersect.
Answer:
A (NO) B(YES) C(YES)
Step-by-step explanation:
Law of sines is used to find the measurements of angles not sides. Law of cosines is used for the sides. And pythagorean theorum should be obvious as it is based on the sides of a right triangle.
