Answer:
<15,-21>
Step-by-step explanation:
u = <3, -1>
v = <-6, -6>
9u + 2v
9 <3, -1>+2 <-6, -6>
<27, -9> + <-12,-12>
<15,-21>
Step-by-step explanation:
- 25.6÷8= 3.2
- 32.4÷6= 5.4
- 16.8÷1.2= 14
- 33.6÷1.6= 21
Answer:
And step-by-step explanation
Answer:
97.5 m^2
Step-by-step explanation:
Given data
Length = 65m
Width= 30m
We are told that the width of the path= 1.5m
Hence the area of the path is
=65*1.5
=97.5 m^2
Answer:
The answer is 1: 50000... If you look down here↓:
Step-by-step explanation:
With a scale of 1:20000, a unit length on the map represents a length of 20000. So 1 cm^2 = 1 cm* 1 cm which represents 20000*20000 cm^2 will be = 4*10^8 cm^2.
50 cm^2 represents that 4*50*10^8 cm^2 = 200* 10^8 cm^2.
Now, on the other hand, the map has the same. 200* 10^8 is represented by 8 cm^2. So the scale is sqrt [ 200* 10^8 / 8 ] = sqrt [ 25* 10^8 ] = 5* 10^4 = 50000.
Therefore the scale on the second map is 1: 50000.
