Answer:
C = 16
Step-by-step explanation:
Substitute r = 8 into the equation for C, hence
C = 2r = 2 × 8 = 16
1) The scale factor is 0.25 is true.
Step-by-step explanation:
Step 1:
The first figure is dilated to form the second figure. The shape is a rhombus.
It is given that the side length of the first figure is 5.8 and the side length of the second figure is 1.45.
Step 2:
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the side length of the rhombus.
The scale factor
So the scale factor is 0.25. This is the first option.
Answer: c
Step-by-step explanation:
men- 24
women- 28
for every 6 men there are 7 women on the plane bc 28/24= 1.16
1.16 x 6=7 women
Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
