If √7 = 2.646, find without using calculator,<br>the value<br>of<br>√0.0007

Varvara68 [4.7K]

Answer:

√0.0007 = 0.02646

Step-by-step explanation:

We know that:

√7 = 2.646

We want to find the value of:

√0.0007

Also we know the relations:

$\frac{\sqrt{x} }{\sqrt{y} } = \sqrt{\frac{x}{y} }$

Then:

$\sqrt{0.0007} = \sqrt{\frac{7}{10,000} }$

We can rewrite this as:

$\sqrt{\frac{7}{10,000} } = \frac{\sqrt{7} }{\sqrt{10,000} } = \frac{2.646}{100} = 0.02646$

The cost for River Z is the sum of the deposit and the hourly cost, so is ...

c = 13+4n

These equations and their graphs are shown in the attachment. The graphs cross where n=7, indicating you have to rent a canoe for 7 hours for the cost to be the same on both rivers.

Katie went to buy a new tv and finds one for $550.00. In the state of Texas, there is a 6% sales tax on items. How much did Kati

kvv77 [185]

Answer:

583$

Step-by-step explanation:

6% is equal to 0.06, so you multiply 550 by 0.06. which equals 33. Then, because it asks for how much Katie played, including the tax and TV, you add 33 to 550.
