William has a 26 -liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill th
Ann [662]

Answer: 0.06 litre or 60 ml


Step-by-step explanation:

Given: The capacity of glass tank= 26 liter

If he add 20.9 liters of water after 85 marbles to fill it completely, then

The volume of 85 marbles= 26-20.9=5.1\ liters

Since, the marbles have same volume.

∴ Volume of each marble= \frac{\text{volume of 85 marbles}}{\text{85}}

⇒ Volume of each marble=\frac{5.1\ litre}{85}=0.06\ liters

In milliliters, Volume of each marble=0.06\times1000=60ml

How to subtract a radical from a whole number?
OLEGan [10]
Although a radical cannot be expressed as a terminating or recurring decimal or a fraction, it can be approximated. This approximation can be expressed as a decimal or a fraction. So if a decimal, ordinary rules of arithmetic apply.
If a fraction, ordinary rules for subtracting fractions apply.
EXAMPLE
99/70 is a good approximation for √2. Let’s see how we would calculate 5-√2=5-99/70=(350-99)/70=251/70=3⁴¹⁄₇₀.
√2=1.4142 to 4 places of decimals. So 5-√2=5-1.4142=3.5858. When we work out 3⁴¹⁄₇₀ as a decimal to 4 places we get 3.5857.
So treat radicals like other real numbers. When giving an answer you may need to say what accuracy you are using (so many decimal places) or the question may tell you how many decimal places are needed.

I need help in the name of chocolate milk
Ganezh [65]

Answer:

<u>The correct answer is A. 1.</u>

Step-by-step explanation:

We have the following rational number expression and it's been asked to find the result and express it in the simplest form:

1/5 + 4/3 * 3/5

Using Operations order, we will proceed this way:

1/5 + (4/3 * 3/5)

1/5 + 4/5 (We eliminate 3 in the numerator and in the denominator)

(1 + 4)/5 = 5/5 = 1

<u>After using Operations order and simplifying, the correct answer is A. 1.</u>
