2941526 mi^2
The first thing you should know to solve this problem is the following conversion:
1mi = 1609.34m
Applying the conversion we have:
2941526 * (1609.34 / 1) ^ 2 = 7.61848E + 12 m ^ 2
Answer:
The land area of Australia in square meters is:
7.61848E + 12 m ^ 2
Answer:
300 minutes
2:00 p.m
Step-by-step explanation:
Given the following:
Time taken to mark a script :
Mrs Kanja = 5mins
Miss Kanene = 4mins
Mrs Nyaga = 12 mins
Number of scripts = 160
Start time = 9:00 a.m
Rate at which each of them mark:
Mrs Kanja = t / 5
Miss Kanene = t/4
Mrs Nyaga = t/12
Combined rate :
t/5 + t/4 + t/12 = 160
(12t + 15t + 5t) / 60 = 160
32t / 60 = 160
32t = 160 * 60
32t = 9600
t = 9600 / 32
t = 300 minutes
300 minutes = 300/60 = 5hrs
9:00 a.m + 5 hours = 2:00 p.m
Fist plug in 7 in to the X values like so 12 (3 (7) +5 (7)) then solve in side the parenthesis 3×7 =21 and 5×7=35 then add them 35+21=56 and then you are left with 12(56) or 12×56= 672
First off what ummmmmm section of mathmatics are you doing?
A., because to find LCD, you must find the LCM of the three denominators. In this case, one of the denominators has the answer, which is 16, because 2, 8, and obviously 16 all go into 16.
You then have to also multiply the numerators by the same number that you are multiplying the denominators by. 2 x X = 16 -> X = 8, so you multiply 1 x 8 and get 8, so the first fraction is 8/16. 16 x X = 16 -> x = 1, 3 x 1 = 3, so the next one remains 3/16. 8 x X = 16 -> X = 2, 2 x 7 = 14, so the last one is 14/16.
