She stayed 5 nights. If you subtract 620 by 124, 5 times you will see. basically 124 * 5 is 620
Answer:
The coordinates for point a will be (5,0)
Step-by-step explanation:
a=(xa,ya)=?→xa=?, ya=?
b=(-3,4)=(xb,yb)→xb=-3, yb=4
Midpoind: m=(1,2)=(xm,ym)→xm=1, ym=2
1) xm=(xa+xb)/2
Replacing the known values:
1=(xa+(-3))/2
1=(xa-3)/2
Solving for xa: Multiplying both sides of the equation by 2:
2(1)=2(xa-3)/2
2=xa-3
Adding 3 both sides of the equation:
2+3=xa-3+3
5=xa
xa=5
2) ym=(ya+yb)/2
Replacing the known values:
2=(ya+4)/2
Solving for ya: Multiplying both sides of the equation by 2:
2(2)=2(ya+4)/2
4=ya+4
Subtracting 4 both sides of the equation:
4-4=ya+4-4
0=ya
ya=0
a=(xa,ya)→a=(5,0)
In both the figures we have a Right Angled Triangle.
Two sides of the right angled triangles are given and we are to find the Third side. This can be done using the Pythagoras Theorem, which states:
Hypotenuse² = Base² + Perpendicular²
For 1st figure, we have
Base = 21
Perpendicular = 20
So,
Hypotenuse² = 20² + 21² = 841
⇒
Hypotenuse = 29 (1st option is correct)
For 2nd Image, we have
Base= 6
Hypotenuse = 10
So, we can write:
10² = 6² + Perpendicular²
Perpendicular² = 64
⇒
Perpendicular = 8 (Option Fourth)
81=81•2/2=162/2
81 1/2=162/2+1/2
=163/2
So 81 1/2=163/2=81.5
