Answer:

If the rational number is a fraction (of course) divide it. For example, 1/2 can be divided as 1 divided by 2 which is 0.5.

If the number is an integer, you can simply just add .0 (point zero). For example, if the rational number is 12, the decimal version would be 12.0.

If the number is a fraction, you can divide the numerator by the denominator. For example, if the rational number is 1/10 (one tenth), just can divide one by zero to get 0.1 (zero point one).

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

Verizon [17]

Answer:

The volume of the full bottle of Jun's favorite hot sauce in ml is $\frac{10x}{9}$ .

Step-by-step explanation:

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

So, to find the volume of a full bottle of Jun's favorite hot sauce in milliliters, we can use the unitary method.

Then, 90% of the full bottle sauce is equal to x ml.

So, 1% of the full bottle sauce is equal to $\frac{x}{90}$ ml.

Therefore, 100% of the full bottle sauce is equal to $\frac{x}{90}\times 100 = \frac{10x}{9}$ ml.

Therefore, the volume of the full bottle of Jun's favorite hot sauce in ml is $\frac{10x}{9}$ . (Answer)

Thirty seven divided by nine

Sunny_sXe [5.5K]

Answer:

4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))

Step-by-step explanation:

To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.

To solve it through long division,

9 can go into 3 zero times

9 can go into 37 four times though

9*4 is 36

So subtract 36 from 37, leaving 1.

9 can go into 1 zero times.

Add a zero behind the one and 9 can go into 10 once.

The pattern continues forever, making the answer 4.1(with the one repeating)

or 4.11 (rounded to the hundredth place)

If you need anymore clarification I can certaintly help.

The regression equation = 3.648 × 1.182

ziro4ka [17]

Solution: The regression equation is:

$y=3.648 \times 1.182^{x}$

Where x is the number of years since it opened in 2003.

We have to find the cost of a vehicle to drive through the safari in 2008.

$\therefore x= 2008 - 2003=5$

Therefore using the given equation, we have:

$y=3.648 \times 1.182^{5}$

$=3.648 \times 2.3072$

$=8.42$

Therefore, the best estimate for the cost of a vehicle to drive through the safari in 2008 is $8.42.

Hence the option C.$8.42 is correct

In Elizabeths town streets run east and west and avenues run north and south each street and avenue is one block apart. if eliza

emmainna [20.7K]

The <em><u>correct answer</u></em> is:

15 blocks.

Explanation:

"As the crow flies" means in a straight line. This will be a diagonal line connecting the two locations.

Elizabeth's house can be represented by the ordered pair (1, 4), where the x-coordinate represents the street number and the y-coordinate represents the avenue number. Using this same system, the restaurant is represented by the ordered pair (10, 16). To find the length of the line segment that would connect the we use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
\\=\sqrt{(10-1)^2+(16-4)^2}
\\=\sqrt{(9)^2+(12)^2}
\\=\sqrt{81+144}=\sqrt{225}=15$
