                       log(4)  +  log(2)  -  log(5)

                 =    log(2²) +  log(2)  -  log(5)

                 =    2 log(2) + log(2)  -  log(5)

                 =      3 log(2)  -  log(5)

                 =      log(2³)  -  log(5)

                 =        log (2³/5)

                 =        log (8/5)

                 =        log (1.6)  =  0.2041...  (rounded)

<h2><u>Answer With Explanation:</u></h2>

<u>Firstly, let's start with <XOZ: =55°</u>

We know that <ZOQ is 70° and angles on a line add up to 180° so we do 180-70=110 110 divided by 2 = 55 so the 2 angles (XOZ & XOP are 55)

<u>Secondly, <OMN, <MON & <ONM = All are 60°</u>

These 2 angles are joined to create an equilateral triangle which always adds up to 180°

So, there are 3 points to this triangle, therefore we divide 180 by 3 which is 60. The angles are 60°

<u>Thirdly, <QON: =55°</u>

This angle lies on the line XON which needs to add up to 180°

As we worked out before, <XOZ was 55°

So, <ZOQ was already given as 70°

We then do 55+70=125 then 180-125=55°

<QON is 55°

(I'm only in Grade 9 LOL)

Felix says that 2,000 + 400 + 70 is another way to write 2,407. What is Felix’s error
Umnica [9.8K]

2,000 + 400 + 70 would equal 2,470.

The correct way to write it would be 2,000 + 400 + 7
