I am pretty sure it's 82/100.
Answer:
(4,-2)
Step-by-step explanation:
Start off by doing everything in the parenthesis which is everyone of them so 2x-1=-2 , your problem then should look like this:
-2(3x2-5x+2) carry the 2 over so multiply the 2 to everything so
(-6x-4+10x+2) add like numbers
10x+-6=4
-4+2=-2
(4,-2)
Decimal places mean we just start counting immediately after the decimal point, so:
2dp: 0.00
1dp: 0.0
Significant figures, we start counting starting at the first non zero number
So we start counting at the 9, therefore:
2sf: 0.00097
3sf: 0.000965
Answer:
225 m³ or 225 cubic meters
Step-by-step explanation:
Actually it has 5 sides, the 2 bases, the 3 lateral faces.
The formula for the volume of a triangular prism is: 
Using the given measurements, we get:
The volume of the prism is 225 m³
Add 4/5 and 1/5 to make 5/5 or 1 mile the subtract 1 from 2 1/2 to equal 1 1/2 miles
