Answer:
The two equations are not equivalent and no property is used.
Step-by-step explanation:
54 - (30 - 8) ... (i)
(54 - 30) - 8 ... (ii)
Solving (i) and applying PEMDAS:
We open the brackets first;
54 - 30 + 8 = 54 + 8 - 30 = 32
Solving (ii) and applying PEMDAS:
We open the brackets first;
54 - 30 = 24
24 - 8 = 16
Answer:
8/32;
Step-by-step explanation:
8/32 is equivalent to 1/4 which percentage is 25
Its the problem where we can use diagram.
So take the look
300+10+10+10+10+10+10+10+10+10+10=300+10*10=400
There was 10 steps
Now we can just add 10 Hans's steps to 400
400+10*100=1400 (times 100 because Hans counted back by hundreds)
The answer is 1400.
Answer:
sin 60° = 1/2 √3
B. √3/2
Step-by-step explanation:
sin 0° = 0
sin 30° = 1/2
sin 45° = 1/2 √2
sin 60° = 1/2 √3
sin 90° = 1
