Answer: B.
Explanation:
Consider any right triangle that has both its legs of same length. In this case both the other two angles would be 45 degrees each. Now, if both its legs are considered of unit length, then hypotenuse would be of length √2.
The cos 45 = 1/√ 2 = √ 2/2

Answer:
The approximate time that it will take Mary to save R40000 is 29 years
Step-by-step explanation:
A= p(1+r/n)^nt
t = log(A/P) / n[log(1 + r/n)]
A = R40000
n = 4
P = R400
r = 16%
t = log(A/P) / n[log(1 + r/n)]
= log(40,000 / 400) / 4{log(1+0.16/4)}
= log(100) / 4{log(1+0.04)}
= 2 / 4{log(1.04)}
= 2 / 4(0.0170)
= 2 / 0.068
= 29.41
t = 29.41 years
Approximately 29 years
The approximate time that it will take Mary to save R40000 is 29 years
So if it wants to know which fraction is greater, your going to need to find a common denominator (the bottom number)
7/12 & 5/6 6 and 12 have a least common multiple (LCM) of 12... this means that both six and 12 can go into twelve. now you convert the fraction's numerator so it equals everything correctly. Now, since 7/12 already has a denominator of twelve than that means that you dont need to change it. but with 5/6 you need to multiply it by 2. (since 6x2=12)
so now it is 10/12 & 7/12. which one now has the bigger numerator?
A:10/12 > 7/12
for adding the two fractions, you also convert the denominator so it equals 10/12 and 7/12 then just add the numerator
A: 17/12(this is in improper form) so now it's 1 5/12
do the same thing with subtracting but then subract instead of add (obviously)
A: 10/12-7/12= 3/12 which can be simplified into 1/4
when multiplying a fraction, you don't need to change anything, just multiply right across, so 7x5=35 and 12x6=72
A: 35/72
Now try the other one on your own using the instructions i gave you!
