Answer:C 2.0< t < 2.50
Step-by-step explanation:
Diameter of circular lake = 2 miles
Radius of the circular lake= 1 mile
Circumference of the circular lake = 2 pi
Speed of Joanna = 3mph
Time t= distance/ speed = circumference of lake / speed
t = 2 pi/ 3 = (2 × 3.142) / 3
t = 6.284/3 = 2.09
This is greater than 2 but less than 2.5, therefore statement C is correct

Answer:
∠BIJ ≅ ∠CGJ and ∠BJI ≅ ∠CJG
Step-by-step explanation:
We have that the initial triangles are equal. Let us check which components remain within the final triangles as the same. The only such components are the angles B and C. We now know that we have to apply a triangle equality criterion.
The triangles BGH and CIH are equal since the have 2 common sides and the respective interior angles are equal. Then we have that BI=GC and also that the respective angles B and C are equal. THen also HIJ=HGJ since they fill to 180 degrees with angles that are equal.
Hence by angle-side-angle the triangles BJI and CJG are equal.
∠BIJ ≅ ∠CGJ and ∠BJI ≅ ∠CJG
Answer:
4 °C
Step-by-step explanation:
In Nuuk the average high is -6 °C, and the average low is -10 °C.
Net change is the difference between the high and the low values, here is called average net change because average values of high and low temperatures are used. Then, the average net change is: (-6) - (-10) = 4 °C
