Answer:
40 km/h
Step-by-step explanation:
rate of change of distance = speed
speed = distance/time
speed = (400 km)/(10 h)
speed = 40 km/h
I cannot see the equation
Answer:
l=15 m
Step-by-step explanation:
Given that a blueprint of a plot of land has a scale of cm to m.
i.e. if it measures 1 cm in blue print actual dimension is 1 m.
The length of land measures 15 cm on the blueprint.
For 1 cm actual length = 1 m
So for 15 cm actual length = 15 m
So we get
if l represents the length of the actual piece of land,
l=15 m
Answer:
12 discs
Step-by-step explanation:
Sheet metal has dimensions of 56 cm by 33 cm. This indicates that it is a rectangle.
A_rectangle = length × width
A_rect = 56 × 33
A_rect = 1848 cm²
It is now melt down and recast into disc's of 7 cm radius and similar thickness.
Thus;
Area of one disc = πr² = π × 7² = 49π
Thus,number of disc's cast = 1848/49π
number of disc's cast = 12
