Answer:
1728
Step-by-step explanation:
You could write it like this
5.4 * 10^5 * 3.2 * 10^-3
You could do this by multiplying the numbers first
5.4 * 3.2 = 17.28
Now work with the powers of 10
10^5 * 10^-3 = 10^(5 - 3) = 10^2
10^2 = 100
So the answer is 17.28 * 100 = 1728
Answer:
25 < t < 350
Step-by-step explanation:
The mean lifetime of a bulb ranges from 25 to 350 hrs but the question is unclear.
Answer:
6a) 1
6b) 11
7a) 4
7b) 10
8a) 6
8b) 14
9a) 11
9b) 13
Step-by-step explanation:
In order to make a triangle, we need to follow this property:
a <= b + c
(Known as "triangle inequality")
Where 'a' is the bigger side and 'b' and 'c' are the other two sides.
So, using this property, we can solve the following problems:
6a) Maximum side will be 6:
6 <= 5 + c
c = 1
6b) Minimum sides will be 5 and 6:
a <= 5 + 6
a = 11
7a) Maximum side will be 7:
7 <= 3 + c
c = 4
7b) Minimum sides will be 3 and 7:
a <= 3 + 7
a = 10
8a) Maximum side will be 10:
10 <= 4 + c
c = 6
8b) Minimum sides will be 4 and 10:
a <= 4 + 10
a = 14
9a) Maximum side will be 12:
12 <= 1 + c
c = 11
9b) Minimum sides will be 1 and 12:
a <= 1 + 12
a = 13
Answer:
Step-by-step explanation:
For A you can use angles in a triangle adding to 180 degrees.
For a you can use the sine rule.
From there you can use Pythagoras to work out c.
Hope this helps :)
