Answer:
0.54kilometres
Step-by-step explanation:
a)actual distance =2.7*20000
=54000cm
=0.54kilometres
The length of AC is found using the Pythagorean theorem which is a^2+b^2=c^2.
In this case your equation would look like 4^2+4^2=c^2.
Four to the power of two is 16 so 16+16=c^2.
16+16=32
32=c^2
Root 32 = c
Length AC is root 32.
I'm not familiar with the use of square brackets/parentheses
I'm assuming it wants (3x15) times (2x10) then that times'd by 2x.
150-2x(900)
150-1800x doesn't make sense however. Can you rephrase the question?
Answer:
Writing it in matrix form
- 2 - 4 - 5 - 155
1 1 6 101
2 2 - 3 37
I hope this helps you
It is! When you're doing a fraction specifically like that, the denominators cancel out. Therefore you can get rid of the 12. It just becomes 21/7, which as you know is 3.
Hope that helps :)
