Answer: a+b=b+a is a clear example of commutative property.

Step-by-step explanation: The commutative property applies to addition and multiplication. The property states that terms can “commute,” or move locations, and the result will not be affected. This is expressed as a+b=b+a for addition, and a×b=b×a for multiplication. The commutative property does not apply to subtraction or division.

Answer:

mold B

Step-by-step explanation:

The molds are of cylindrical shape. The volume of a cylinder is given by:

Volume = πr²h

where r is the radius and h is the height.

For mold A: diameter = 2 inches, hence radius = 1 inch. Height = 7 inches

volume = π(1²)7 = 7π in³

For mold B: diameter = 2 inches, hence radius = 1 inch. Height = 4 inches

volume = π(1²)4 = 4π in³

For mold C: diameter = 3 inches, hence radius = 1.5 inch. Height = 3 inches

volume = π(1.5²)3 = 6.75π in³

For mold C: diameter = 4 inches, hence radius = 1.5 inch. Height = 3 inches

volume = π(2²)3 = 12π in³

Therefore mold B has the smallest volume

There are 16 different relations on the set {0, 1}, which can be represented as the power set of the Cartesian product {0, 1} x {0, 1}. These 16 relations are:

1. {} (the empty set)

2. {(0,0)}

3. {(0,1)}

4. {(1,0)}

5. {(1,1)}

6. {(0,0), (0,1)}

7. {(0,0), (1,0)}

8. {(0,0), (1,1)}

9. {(0,1), (1,0)}

10. {(0,1), (1,1)}

11. {(1,0), (1,1)}

15. {(0,1), (1,0), (1,1)}

16. {(0,0), (0,1), (1,0), (1,1)}

Out of these 16 relations, the ones that contain the pair (0, 1) are:

3. {(0,1)}

6. {(0,0), (0,1)}

9. {(0,1), (1,0)}

10. {(0,1), (1,1)}

The amount of money you have in your account after years 1, 2, 3, and 4 are $102.25, $204.5, $306.75 and $409 respectively.

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan.

Given that, you have 100 dollars in your bank account, and you earn 2.25% interest per year.

We need to find the amount of money you have in your account after years 1, 2, 3, and 4 years

Find for Simple interset :-

Simple interset = PRT / 100

P = Principal amount, r = rate and  t = year

For 1 year, put t = 1

A = 100×1×2.25 / 100 + 100

= $102.25

To find the amount for 2nd, 3rd and 4th year, just multiply these numbers to the interset earned in 1st year,

For 2 year,

A = $102.25×2

A = $204.5

For 3 year,

A = $102.25×3

A = $306.75

For 4 year,

A = $102.25×4

A = $409

Hence, the amount of money you have in your account after years 1, 2, 3, and 4 are $102.25, $204.5, $306.75 and $409 respectively.

The difference of 32 and x is simply 32 subtracted by x. In other words, it is the result of subtracting the value of x from 32. The answer to this expression will depend on the value of x.

For example, if x is 10, then the difference of 32 and x would be 22 (32 - 10 = 22). If x is 25, then the difference of 32 and x would be 7 (32 - 25 = 7).

In general, if x is less than 32, then the difference of 32 and x will be a positive number, and if x is greater than 32, then the difference of 32 and x will be a negative number.

It is important to remember that the order of the subtraction matters in this expression. If we were to reverse the order and instead write x minus 32, then the result would be different. For example, if x is 10, then x minus 32 would be -22 (10 - 32 = -22). If x is 25, then x minus 32 would be -7 (25 - 32 = -7).

The requried, 140% is equivalent to 7/5 as a fraction, 1 2/5 as a mixed number, and 2 as a whole number.

To write 140% as a fraction, we first recognize that "percent" means "per hundred," so 140% can be written as the fraction 140/100. We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 20:

140/100 = 7/5

To write 7/5 as a mixed number, we divide the numerator by the denominator and express the result as a whole number plus a fraction. In this case:

7 ÷ 5 = 1 with a remainder of 2

So 7/5 can be written as the mixed number 1 2/5.

To write 7/5 as a whole number, we can round it to the nearest whole number. Since 7/5 is greater than 1.5 and less than 2.5, it rounds to 2.

It will take 10 years for the account to reach $200, as determined by solving the equation A = \(325(1 + 0.047/12)^(12t)\) for t.

\(A = 325(1+0.047/12)^(12t)\)

\(200 = 325(1+0.047/12)^(12t)\)

\(200/325 = (1+0.047/12)^(12t)\)

\(log_((1+0.047/12))(200/325) = 12t\)

\(t = log_((1+0.047/12))(200/325) / 12\)

t = 8.75 years

It will take 9 years for the account to reach $200.

Hassan deposited $325 into an account that pays 4.7% annual interest compounded monthly. We can use a system of equations to determine how many years it will take for the account to reach $200. To do this, we first write an equation to represent Hassan's account balance A after t years. This equation is\(A = 325(1+0.047/12)^(12t)\). We then solve for t by taking the logarithm of both sides, which gives us means that it will take 8.75 years for the account to reach $200, which we round up to 9 years.

Interference is a property of ALL the given wave options, which are light waves, sound waves, and water waves.

Interference is the phenomenon of two or more waves combining to form a resultant wave of greater, lower, or the same amplitude.

When two waves meet at the same point at the same time, they either combine constructively (resulting in the formation of a wave of greater amplitude) or destructively (resulting in the formation of a wave of lower amplitude).

For instance, when two sound waves or light waves meet, they create a resultant wave whose amplitude is equal to the sum of the two original waves.

This is known as constructive interference.

On the other hand, when two waves meet and their amplitudes are in opposite directions, they produce a resultant wave whose amplitude is equal to the difference between the two waves.

This is known as destructive interference.

Answer The dimensions of the room in inches on the scale drawing is inches by inches OR 3.25 inches by 3.75 inches

Step-by-step explanation:

From the question, the dimension of the room is 13feet by 15feet.

Now, if the room is drawn to 1/4 inch represents 1 foot scale, i.e 0.25 inch represents 1 foot, then the dimension of the room in inches on the scale drawing can be determined as follows

Since 1 foot = 0.25 inch  

∴ 13 feet on the scale drawing will be 13 × 0.25 = 3.25 or 3 1/4 inches

and 15 feet on the scale drawing will be 15 × 0.25 = 3.75 or 3 3/4 inches

Hence, the dimensions of the room in inches on the scale drawing is

Based on the sequence of numbers given, the number that is represented by the question mark is 2679 = 2.

The sequence requires that you count the number of circles that a group of number has. For instance 9 has one circle and 8 has two circles because of the way they are drawn.

The numbers 111, 3213, and 1234 will therefore be equal to 0 because there is no number that has a circle in it.

The number 8096 however, will be equal to 5 because there are 5 circles. Two in 8. 1 in 0. 1 in 9. 1 in 6.

This means that the last number of 2679 will therefore be equal to 2 because there are two circles. One circle is in 6, and the other circle is in  9.
