The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.

To calculate 6 divided by 20, you simply perform the division operation. Divide the numerator (6) by the denominator (20):

6 ÷ 20 = 0.3

The result of 6 divided by 20 is 0.3. This means that if you divide 6 into 20 equal parts, each part will be 0.3.

In decimal form, the fraction 6/20 is equivalent to 0.3. Decimal notation is useful when dealing with fractions that don't easily simplify into whole numbers. In this case, the division results in a decimal less than 1, representing a fraction that is less than a whole. The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.

-Use Distributive Property:

[tex]4(3x + 2) - 6[/tex]

The first step is to distribute the 4 to the parenthesis. This turns the equation into:

We can remove the parenthesis now. Also, now we combine like terms. There are no other variables in the equation, so we leave the 12x alone. Combine the +8 and the -6 to get +2. This leaves the equation at:

It takes a boat 3 hours to travel 45 miles downstream and 4 hours to travel 44 miles upstream.
What is the speed of the boat in still water?
The boat travels at...
miles per hour in still water.
What is the speed of the current of the river?
The speed of the current is...
miles per hour.

Answers

Answer:

2 miles per hour

Step-by-step explanation:

We use the distance formula. D = r * t

45/3 = 15 mph | Trip 1 |

44/4= 11mph | Trip 2 |

15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.

Answers

Answer:

a) 0.2 L

b) 4800 ml

c) 2400 ml

Step-by-step explanation:

Total volume of water = 5 litres

Since 1000 milliliters make 1 L

5L = 5000 ml

a) litres of water spilt = 200/1000 = 0.2 L

b) milliliters of water remaining = 5000 - 200 = 4800 ml

c) since it was expressly stated in the question that the remaining water was divided evenly; 4800/2 = 2400 ml in each bowl

Answer:

Step-by-step explanation:

TU is parallel to IJ.  So ∠I and ∠T are corresponding angles, and ∠U and ∠J are corresponding angles.

By AA similarity, ΔHTU and ΔHIJ are similar.

Write a proportion:

HT / HI = HU / HJ

Plug in values:

4 / 10 = x / (x + 9)

Cross multiply:

4 (x + 9) = 10x

4x + 36 = 10x

36 = 6x

x = 6

So HU = 6, and HJ = 6 + 9 = 15.

Step-by-step explanation:

Given

[tex]1256^{-4}[/tex]

Required

Write as an exponent of positive number

From law of indices, we have that:

[tex]a^{-b} = \frac{1}{a^b}[/tex]

So:

[tex]1256^{-4}[/tex] becomes

[tex]\frac{1}{1256^4}[/tex]

1 to the power of any digit is 1,

So, the above can be rewritten as:

[tex]\frac{1^4}{1256^4}[/tex]

Apply the following law of indices:

[tex]\frac{a^m}{b^m} = (\frac{a}{b})^m[/tex]

So:

[tex]\frac{1^4}{1256^4}[/tex] becomes
