(1.3X10^6ft/hr)(2.8X10^3hr)
(1.3*2.8)(10^6*10^3)
Rule (a^b)(a^c)=a^(b+c)
(3.64)(10^(6+3))
3.64(10^9)
3.64X10^9 ft
Technically we only had two significant figures and the answer should be:
3.6X10^9 if we were to express our answer to the correct number of significant figures....
A) ( 25 / 100 ) * 100 = 25 m ;
b) ( 30 / 100 ) * ( 1205 / 100 ) = 36150 / 10000 = 3615 / 1000 = 3,615 km ≈ 3,62 km ;
c) ( 40 / 100 ) * 60 = ( 4 / 10 ) * 60 = 4 * 6 = 24 m^2 ;
d) 3 1 /3 = 10 / 3 ;
( 32 / 100 ) * ( 10 / 3 ) = 320 / 3 = 106,66 kg;
e) ( 1 / 10 ) ÷ 100 * 10 = ( 1 / 10 ) * ( 1 / 100 ) * 10 = 1 / 100 = 0,01 l ;
Good luck !
Answer:
k = 4
Step-by-step explanation:
Rearrange so that like terms are on either side of the equation
4k - 2k - 2k + 2k = 5 + 3
Simplify
2k = 8
Divide both sides by two to make k on its own
k = 4
You are correct, well done!
2x^2 + 3x + 8 = 0
Answer: B) -3 + I √55 over 4.
