1inch= 0,8(3) feet
5,400*0,8333 : 5280= 4,4999 :5280=0, 085 miles
Step-by-step explanation:
Pythagoras (for right-angled triangles) :
c² = a² + b²
c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.
c = diagonal = 10 ft
therefore, the width of the rectangle is 10/2 = 5 ft
10² = 5² + b²
100 = 25 + b²
b² = 75
b = length = sqrt(75) = 8.660254038... ft
Answer:
AB = DF (Proved below)
Step-by-step explanation:
Here,
CE = CD + DE [since D is a point over CE]
= DE + EF [ Since, CD = EF (given)]
= DF [ Since, E is a point over DF] ---------------(1)
Again,
AB = CE (given) ------------------------(2)
So from (1) and (2),
AB = CE = DF
⇒ AB = DF (Proved)

bit.
Step-by-step explanation:
15x7=105 years
9x5=45 years for the boys
105-45=60 so 60years girls
