Answer:
1.62m^2
Step-by-step explanation:
From the problem statement, the scale of the drawing is
1cm:45cm (meaning that 1cm on the drawing represent 45cm in reality ofr actual)
first,let us convert 20cm to the actual drawing
20cm in actual will give 20*45=900cm
to meters =900/100= 0.9m
Secondly let us convert 40cm to the actual drawing
20cm in actual will give 40*45=1800cm
to meters =1800/1000= 1.8m
Now we can calculate the actual area in meters we have
area= 0.9*1.8
area= 1.62m^2
I guess you want to find the average speed for the whole journey
average speed = distance travelled / time
the distance from home to the shop = speed * time = 0.5*10 = 5 miles
time for travelling back = distance / speed = 5/30 = 1/6 hours
average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
Answer: 48hm
Step-by-step explanation:
48hm = 4800m
480m < 4800m
Y=a (x-h)^2+k
y=a (x-3)^2+(-12)
plug in your point (0,6)
6=a (0-3)^2-12
6=a (9)-12
6=a (9) also seen as
6= 9a-12
now add 12 on both sides
18=9a
divide
2=a
y=2 (x-3)^2-12
