Answer:
Claire is standing at a distance of 485.45 meters to Chloe.
Step-by-step explanation:
The track is a circular with a radius of 100 meters.
The total length of the circular track = length of the circumference of a circle
But, length of the circumference of a circle = 2
r
So that,
total length of the circular track = 2r
= 2 × 
× 100
= 628.57
The total length of the circular track is 628.57 meters.
Thus,
the distance of Claire to Chloe = total length of the circular track - distance of Chloe to Claire
= 628.57 - 143.12
= 485.45
This means that Claire is standing at a distance of 485.45 meters to Chloe.
Answer:
x = 30°
2x = 60°
3x = 90°
Step-by-step explanation:
GBF = CBD (opposite angle)
; 2x+x+3x = 180° (Size of straight angle)
6x = 180
x = 180÷6
x = 30°
substitution x in 2x ; 2×30 = 60°
substitution x in 3x ; 3×30 = 90°

Answer:
Dulcina's collection has 57 pins
Eva's collection has 25 pins
Step-by-step explanation:
first we are going to represent the relation of pins by means of an equation
d = Dulcina
e = Eva
e + d = 82
and now we represent the relation of the collections of each one
d = e + 32
having the 2 equations we can replace the d by (e + 32) and place it in the other equation
e + d = 82
e + (e + 32) = 82
2e + 32 = 82
2e = 82 - 32
2e = 50
e = 25
Now we replace e with 25 in the second equation and get the value of d
d = e + 32
d = 25 + 32
d = 57
