How many liters are equal to 2,396 milliliters? Use the placement of the decimal point when dividing by a power of 10 to help you solve.

2.396 liters
239.6 liters
23.96 liters
23,960 liters

Answers

2.396 which is also a.

Answer:

2.396

Step-by-step explanation:

The units of measurement go like this:

Kilo, hecto, deca, unit, deci, centi, mili

When you move to the right, you move the decimal one place to the right, and when you move left, you move the decimal one place to the right

If you’re changing milliliters to liters (unit), you have to more the decimal 3 times to the left. This makes it 2.396 liters

Why do equivalent ratios form a straight line when graphed?

The vertical distance between points is constant, and the horizontal distance between points increases with each point.

The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.

The horizontal distance between points is constant, and the vertical distance between points increases with each point.

The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Answers

Answer:

D-The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Step-by-step explanation:

Answers

Answer: 950.3

Step-by-step explanation:

so the formula for the volume of a sphere is 4/3*pi*r^3

so plugging your information into the formula, you would get 4/3(pi)(6.1)^3

6.1^3 is the same as

(6.1) times (6.1) times (6.1)

this equals 226.981

now you have 4/3(pi)(226.981)

now you do 226.981/3 which equals 75.660333

multiply that by 4➡️ 302.6413333333333

now you have to multiply by pi (3.14)

302.6413333333333*3.14=

950.2937866666667

you have to round to the 10ths place

so your answer is 950.3 m cubed.

Step-by-step explanation:

4×28/ 7×1 = 112/7

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

We already did that, and the GCF of 112 and 7 is 7.

We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.

112/7 = 16

and do the same for 3/4 out of 16 then add ur answers

Answers

Answer:

they each hold 1 1/3 litters of cola

Step-by-step explanation:

Because if there is 2 2/3 liters of cola

then you either divide it by 2

or you can look at it and see what would add evenly to make that number

in this case it would be 1 1/3

Devon became a waiter at a fancy restaurant. He makes $9 per hour. One night he made $150 in tips. How many hours did he work if he made a total of $226.50.

Answers

Answer:

9x + 150 = 226.50

Step-by-step explanation:

Devon makes $9 per hour. So, that signalizes "9x" (x representing the amount of hours he worked)

$150 represents how much he made one night, so you would add that to 9x. (9x + 150)

Finally, it gives you the total amount: 226.50

In conclusion, your equation should be: 9x + 150 = 226.50

226.50 is the answer for your question
