Soldering is accomplished by quickly heating metal parts. solder is a metal that is melted to join metallic surfaces together. common solder formulations based on tin and lead are listed below. the fraction represents percentage of tin first, then lead, totaling 100%. tin/lead melting point (°c) 40/60 230 °c 50/50 214 °c 60/40 190 °c 63/37 183 °c 95/5 224 °c with the same soldering iron, assuming the soldering iron’s highest temperature is 204 degrees centigrade, would you be able to make the repair if you had solder made of 50/50?

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

if you get paid hourly because if you get a salary you could work all week and only get paid a certain amount no matter how much you work but if you get paid hourly then you get paid for every minute you worked.

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
