To find the number of black pieces in a checkers game with a black to red ratio of 3:5 and a total of 16 pieces, you can form and solve an algebraic equation, resulting in 6 black pieces.

To determine the number of black pieces in a checkers game when given the total pieces and the ratio of black to red pieces, you can set up a proportion. With a total of 16 pieces and a ratio of 3:5 black to red, we can use algebra to find the answer. Let's denote the number of black pieces as 'b' and the number of red pieces as 'r'.

According to the ratio, we have b/r = 3/5. We also know that b + r = 16 because the total number of pieces is 16. By cross-multiplying the ratio, we get 5b = 3r. We can substitute r with 16 - b in this equation (from our total) to get: 5b = 3(16 - b).

Solving this, we have: 5b = 48 - 3b which simplifies to 8b = 48. Thus, b = 48/8, which means there are 6 black pieces on the board.

Each baker uses (12x - 3.6) / 6 pounds of flour in an hour. The expression equivalent to 12x - 3.6 to represent the total flour used in an hour is 12x - 3.6 pounds.

To find an expression for the number of pounds each baker uses in an hour, we divide the total amount of flour (12x - 3.6 pounds) by the number of bakers (6). Therefore, each baker uses (12x - 3.6) / 6 pounds of flour in an hour.

To write an expression equivalent to 12x - 3.6 to represent the total flour used in an hour, we can simply use 12x - 3.6 pounds, as this already represents the total amount of flour consumed by all the bakers in one hour.

Each baker uses 2x - 0.6 pounds of flour each hour. The expression 12x - 3.6 represents the total flour used by all bakers in an hour, so it's already the equivalent expression needed.

If six bakers use a total of 12x - 3.6 pounds of flour each hour, and each baker uses the same amount of flour, we need to divide the total amount of flour by the number of bakers to find how much flour each baker uses per hour.

Amount of flour per baker per hour = Total flour used / Number of bakers

= (12x - 3.6) / 6

By simplifying this expression, we divide each term in the numerator by 6:

= 12x/6 - 3.6/6

= 2x - 0.6

So, each baker uses 2x - 0.6 pounds of flour each hour.

To represent the total hour used in an hour with an equivalent expression, we can simply rewrite the original expression, as it already represents the total amount of flour used by all bakers in an hour. Thus, the expression equivalent to 12x - 3.6 is already the total amount used in an hour.

Answer:

Yes it is 5

Step-by-step explanation:

The numbers ordered from least to greatest are:

13/20, 4/5, 9/10, 5/4

Basically, we need to order the numbers:

5/4, 9/10, 4/5, 13/20

From smallest to largest.

An easy way of doing that is write all of these fractions as decimals.

5/4 = 1.25

9/10 = 0.9

4/5 = 0.8

13/20 = 0.65

The order is then:

13/20, 4/5, 9/10, 5/4

Any calculator can give you this answer. If you need to use long division, do it normally. The first number you do will equal zero, but that is normal.

Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.843 to the nearest hundredth would give 0.84.

If the thousandths place is five through nine, the hundredths place is increased by one. The decimal 0.846 rounded to the nearest hundredth is 0.85.

So for your case 25.999 rounded to the nearest hundredths would be 26.

Hope this helps :)

To round 25.999 to the nearest hundredths, the rounded answer is 26.

To round 25.999 to the nearest hundredths, we need to look at the digit in the thousandths place which is '9'. Since '9' is greater than or equal to 5, we will round up the digit in the hundredths place by adding 1. Therefore, the number 25.999 rounded to the nearest hundredths is 26.

The length of the line segment that is 75% of the line BC is 6 cm.

In this problem, we are given that line BC represents 200% or twice the length of a line segment. Let's say the length of BC is 8 cm. To find the length of a line segment that is 75%, we can use proportion. Since 75% is three-fourths of 100%, the length of the line segment will be three-fourths of the length of BC.

So, the length of the line segment that is 75% is (3/4) * 8 cm = 6 cm.

Final answer:

The cost of renting a bicycle is expressed as $6 + $3h, which includes a flat fee of $6 plus $3 for each hour the bike is rented.

Explanation:

The cost of renting a bicycle from the rental shop can be described by an algebraic expression that takes into account both the flat fee and the hourly charge. To calculate the total cost, you multiply the number of hours the bike is rented (h) by the hourly rate ($3) and then add the flat fee ($6).

Step-by-Step Calculation

Determine the hourly rental rate: $3 per hour.

Multiply the hourly rate by the number of hours the bike is rented: $3 x h.

Add the flat fee to the hourly charge: $6 + ($3 x h).

Therefore, the expression that describes the cost of renting the bicycle is $6 + $3h.

The number 2.306 can be written in expanded form with multiplication as 2 x 1 + 3 x 0.1 + 0 x 0.01 + 6 x 0.001.

When a number is written in expanded form with multiplication, it means that we break down the number into its individual place values and then multiply each digit by the corresponding place value. For the number 2.306, we can break it down as follows:

2 x 1 + 3 x 0.1 + 0 x 0.01 + 6 x 0.001 = 2 + 0.3 + 0 + 0.006 = 2.306

So, the expanded form of 2.306 with multiplication is 2 x 1 + 3 x 0.1 + 0 x 0.01 + 6 x 0.001.

The number divided by 7,650 by blank equals 7.65 is; 7,650 ÷ 1000 = 7.65

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We need to solve the below expression;

7,650 ÷ ----- = 7.65

Let the blank is x.

7,650 ÷ x = 7.65

Multiplying both sides by 7.65 and cross multiplying :

x = 7,650/7.65

Hence, 7,650 ÷ 1000 = 7.65

Answer:

I agree with the person above me

Step-by-step explanation:

The 1 meter contains 100 centimeters therefore the area of the blanket with dimensions 2.25meters long and 1.8meters wide is 40500 cm².

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

As per the given dimension of the blanket,

Length = 2.25 meters and width = 1.8 meters.

Since,1 meter = 100 cm

Length = 2.25× 100 = 225 cm.

Width = 1.8× 100 = 180 cm

The area of the rectangle is Length × width.

Area = 225 × 180

⇒ 40500 cm²

Hence "The 1 meter contains 100 centimeters therefore the area of the blanket with dimensions 2.25meters long and 1.8meters wide is 40500 cm²".
