number 1 = 1 mark because it only said write the EXPRESSION below to 1 significant figure and estimate the value so the answer would be correct because .4 is equivalent to 2/5 which would be the exact answer before converting the fraction to a decimal if the question is done properly the expression should be √100/20+5 and if you look carefully you'll see that EACH number in my expression has 1 significant figure and the answer would lead to 10/25 simplifying that you will arrive at 2/5 the converting that to sed .4 by division This will ultimately leave you with getting 1 less mark if it is done your way and more chances of picking up an E for reasoning from CSEC
The running laps actually possible its not stupid he runs 18.55 Km in total in 1 hr and the best Half Marathoners can do almost 21km in 1hour so it possible
I really love this teaching where he take his time going step by step and is only one thing i am not getting through
I keep watching sir but the first part of thr equation is 10.3923 but u have a 2 after the point
Because him round it off wid the 9
Mistake I saw it too
SIR I LOVED YOUR TEACHING
Thank you grateful sir 🙏
👍

and this is coming from a student who is about to sit the csec math exam
that commutative frequency question had me in a choke hold wont lie

I am having hard time trying to get 1.050625 on calculator

Ya calculator bad tho me can’t even do mine like that
Get a casio calculator but its expensive if you're in Jamaica I got mine for 5000

Question c answer is incorrect.
I need to you to send it to me
