Answer:
36
Step-by-step explanation:
18 × 2 = 36
Because 1/2 is half of 1 kg so multiply by 2 it makes 1 kg
Answer:
The scale factor of all radii of circle Y to all radii of circle Z is 2.5
Step-by-step explanation:
we know that
The radius of circle Y is 4 units
The radius of circle Z is 10 units
To find the scale factor of all radii of circle Y to all radii of circle Z, divide the radius of circle Z by the radius of circle Y
10/4=2.5
Answer:
The truck
Step-by-step explanation:
You need to first find out how many miles per hour each is going. To do this you need to divide. 480/8=60 210/3=70 with this information you just need to take the one that goes faster which is the truck.
The idea is to use the tangent line to 
at 
in order to approximate 
.
We have
so the linear approximation to 
is
Hence 
and 
.
Then
