Express 30 minutes as a percentage of 3 hours 20 minutes​
liberstina [14]

Answer:

15%

Step-by-step explanation:

The quantities must be in the same units

Using the conversion

I hour = 60 minutes, then

3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.

Thus

\frac{30}{200} × 100% = \frac{30}{2} = 15%

Can someone help me with question e please ? ​
MAXImum [283]

Answer:

Step-by-step explanation:

a) The domain is R- all real numbers.

b) The domain is R- all real numbers.

c) we need

x^{2}-4\neq  0\\x^{2} \neq 4\\x\neq 2\\and\\x\neq -2

So the domain is R\{-2, 2}

d)

we need

x^{2}+x-2\neq  0\\x\neq 1\\and\\x\neq -2

So the domain is R\{-2, 1}

e)

we need: x-1>0 or x> 1

So the domain is (1,+∞)
