Answer:
Ans. 64 cm
Step-by-step explanation:
we have to use the ratio of actual distance and distance on projection here.
Given,
Ratio of distance in projection and actual distance is 1:200,000
That means, 1 cm in projection will be 200,000 cm in actual distance.
Here,
Actual distance is 128 km.
we know, 1 km=100,000 cm
Now, 128 km=128,00,000 cm
So, actual distance is 128 00 000 cm.
Since, 200000 cm in actual distance means 1 cm in projection.
So,
for 12800000 cm in actual distance means 12800000/200000 cm in projection.
So, in the screen distance will be-
12800000 / 200000
=64 cm
First, add 3m to each side of the equation. That would leave you with : -2n=13
Next divide -2 from each side so you can get n by itself.
ANSWER: n= -6.5
A=πr²
A=π·(14mm)²=196π mm²
4. 5x+6.25
5.2x+40
6.3x+ -6
7. 1x+ 1/5
