First off, 'percent' literally means 'per hundred,' so 12.5 'per hundred' = $\frac{12.5}{100}$
$\frac{12.5}{100} = \frac{125}{1000} = \frac{1}{8}$

A taxi journey of 30km cost $3,600.At the same rate per kilometer .A what would be the cost of travelling 25k.B.How far could yo

madreJ [45]

Answer:

The cost of traveling 25km would be $3000.

You can travel 35 km for $4200.

Step-by-step explanation:

Consider the provided information.

For 30km cost $3,600.

30 km = $3600

Divide both sides by 30.

$\frac{30}{30}\text{ km}=\frac{3600}{30}$

$1 \text{ km} =120$ ....(1)

The cost of 1 km is $120.

Part (A) what would be the cost of traveling 25km

Multiply both the sides of equation 1 by 25.

25 km = 3000

Hence, the cost of traveling 25km would be $3000.

Part(B) How far could you travel for $4,200?

Divide 4200 by 120.

$\frac{4200}{120}=35$

Hence, you can travel 35 km for $4200.

Which function has the same domain as y=2 sqrt x

Fiesta28 [93]

The domain of a function is the set of values for which the function is defined; i.e. the function outputs a value for an input from the domain. That means that we must be able to plug in numbers for x and get numbers from y.
We can't take the square root of negative numbers (ignoring imaginary numbers), so that means we can take the square root of any non-negative number; i.e. we can take the square root of zero, and any positive number.
Therefore, any function that can take in values of x that are zero or more than zero has the same domain as the given function. So $y=\sqrt{x}$ is a function that has the same domain as $y=2\sqrt{x}$ .
