So this is a BIDMAS question so first you do what’s in the brackets so you have (1-9x1-4) and you have to do the multiplication first out of that to get (1-9-4) which is -12 so then you have overall 36 / -12 + 1 + 2 so you have to do the division first so do 36/-12 to get -3 and you have -3 + 1 + 2 which is 0 so your answer is 0.
Answer:
p=3 , q=1 , r=2
Step-by-step explanation:
1176=2*2*2*3*7*7
1176=(2^3)*(3^1)*(7^2)
given that 1176 = (2^p)*(3^q)*(7^r)
Comparing Equation 1 & 2
we get p=3 , q=1, r=2
None of the answer matches the correct ans
(3.4×10-14)(1.8×10^28)
20(1.8×10^28)
3.6×10^29
Answer: B and C only
Step-by-step explanation:
The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and rises 4 degrees
Initial temperature = 0
Temperature rise = 4
Fall in temperature = - 4
(Initial temperature + rise in temperature + fall in temperature)
Summing all : (0 + 4 - 4) = 0
carbon atom has 6 negatively charged electrons and 6 positively charged protons.
Net charge of atom :
(number of proton + number of electrons)
( 6 + (-6)) = 0
