Answer:

Step-by-step explanation:

Using the pythagorean theorem, we know that a^2+ b^2=c^2

In our case, we know b, which is 5 and c which is 13.

If we plug that into the equation, we get a^2+ 5^2 = 13^2

Next, we simplify the equation. a^2 + 25 = 169

Then we subtract 25 from 169. 169 - 25 = 144.

Lastly, we do the square root of 144 and we get 12 which is the missing side.

Answer: 12 miles

Step-by-step explanation:

Use Pythagorean Theorem to find the missing side.

a^2 + 5^2 = 13^2

a^2 + 25 = 169

subtract 25 from both sides

a^2 = 144

take the square root of both sides

a = 12

Using the ratio of perfect squares method, what is square root of 14 rounded to the nearest hundredth? Do not use your calculato

Svetlanka [38]

The square root of 14 rounded to the nearest hundredth without using the calculator can be done this way. Follow these steps:
1. Guess
2. Divide
3. Average

GUESS.
1. Make good guess. We'll just use 2

DIVIDE.
2. Divide 14 by our guess of 2 = 7.

AVERAGE.
3. Average 7 and 2: (7+2)/2 = 4.5

Here, we repeat step 2 using 7 as our new guess, 4.5
2. 14/4.5 = 3.1
3. (3.1 + 4.5)/2 = 3.8

2. 14/3.8 = 3.7
3. (3.7 + 3.3)/2 = 3.5

2. 14/3.5 = 4
3. (3.5 + 4)/2 = 3.75

2. 14/3.75 = 3.7
3. (3.75 + 3.7)/2 = 3.725

so on and so forth until the pattern remains in 3.7

Can anyone please help me :)

Solnce55 [7]

Answer:

5 to the 15th power.

Step-by-step explanation:

PEMDAS requires us to do parenthesis, then exponents, and then division. Let's do 5³. 5x5x5 is equal to 125. Now, we find 125 to the ninth power. According to my calculations, 125 to the ninth power is equal to 7,450,580,596,923,828,125. Now, we find 5 to the twelfth power, which, according to my calculations, is 244,140,625. Now, we solve. According to my calculations, 7,450,580,596,923,828,125/244,140,625 is equal to 30,517,578,125. 30,517,578,125 is equivalent to 5 to the 15th power. That means that the second option is correct. I hope this helps!

Janine is considering buying a water filter and a reusable water bottle rather than buying bottled water. Will doing so save her

Whitepunk [10]

The cost of each option is given by the total amount required to obtain

the volume of water Janine drinks in a year.

Responses:

The cheapest option is the faucet-mounted water filter

The cheapest option saves her $79.11 over a year

<h3>How are the different options evaluated?</h3>

Number of bottles of water Janine drinks in a day = 3 bottles

Volume of a bottle = 16.9 ounces

Volume of water Janine drinks in a year = 3 × 16.9 × 365 = 18505.5

Volume of water Janine drinks in a year = 18,505.5 ounces

Volume of water = 18,505.5 ounces = 547.273 liters

The cost of 24-packs of 16.9 ounces bottles = $3.29

Number of packs she will buy in a year is therefore;

$Number \ of \ packs= \dfrac{3 \times 365}{24} = \mathbf{45.625}$

Cost per year = 45.625 × $3.29 ≈ $150.11

The cost of a reusable bottle = $10

Cost of each option to filter 547.723 liters of water.

Total cost of a faucet mounted filter = $10 + $28 + $33 = $71.00

Total cost using the water filter = $10 + $22 + 2 × $20 = $72

The cost of using the under sink filter = $10 + $130 = $140

Therefore;

The cheapest option over one year is the faucet-mounted filter

The amount saved over one year = $150.11 - $71.0 = $79.11
