9/8 is the result when we divide 3/4 by 2/3

Step 1. Take reciprocal of  the second fraction (the one you want to divide by)

Step 2. Multiply the first fraction by the second faction's reciprocal.

Step 3. Convert the result in the lowest form.

When the numerator and the denominator of the fraction do not have any common factors, the fraction is said to be in its simplest form. For instance, 12 is the most basic version of 6/12.

so the result = (3/4) / (2/3)

=> (3/4) * (3/2)

=> (3*3)/(4*2)

=>9/8

so the result obtanied after the above division is 9/8.

The value of x , y and z in the parallel line is 50 degrees.

When parallel lines are crossed by a transversal line, angle relationships are formed such as vertically opposite angles, alternate interior angles, alternate exterior angles, adjacent angles, corresponding angles etc.

Therefore, let's use the angle relationships to find the angle, x, y and z as follows:

Therefore,

x = 360 - 310(sum of angles in a point)

x = 50 degrees

Therefore,

x = y(alternate interior angles)

Alternate interior angles are congruent.

Hence,

y = 50 degrees

Therefore,

x = z(alternate interior angles)

z = 50 degrees.

Answer:

Step-by-step explanation:

b(x) = 18 - 0.5x

b(x) = 18 - 0.5(-2)

b(x) = 18 - (-1)

b(x) = 18 + 1

b(x) = 19

b(x) = 18 - 0.5(0)

b(x) = 18

b(x) = 18 - 0.5(5)

b(x) = 18 - 2.5

b(x) = 15.5

Best of Luck!

The evaluation b(x) = 18-0.5x when I -2,0, and 5 is 19,18, and 15.5.

Given that,

Based on the above information, the calculation is as follows:

b(x) = 18 - 0.5x

= 18 - 0.5(-2)

= 18 - (-1)

= 18 + 1

= 19

b(x) = 18 - 0.5(0)

= 18

b(x) = 18 - 0.5(5)

= 18 - 2.5

= 15.5

Therefore we can conclude that the evaluation b(x) = 18-0.5x when I -2,0, and 5 is 19,18, and 15.5.

The inverse of the statement is "If a number does not have exactly two distinct factors, then the number is not prime." Thus Option 2 is the answer.

   When a conditional statement is reversed, the hypothesis and conclusion are both negated. The hypothesis in the original statement is "a number with exactly two distinct factors," while the conclusion is "is prime."

  To make the inverse, we negate both sections. "A number does not have exactly two distinct factors" is the antonym of "A number that has exactly two distinct factors." "Is not prime" is the opposite of "is prime."

    As a result, the inverse statement is "If a number does not have exactly two distinct factors, then the number is not prime."

     It's crucial to remember that a statement's inverse could or might not be accurate. In this instance, the inverse is true since the definition of a prime number is incompatible with the fact that a number has more than two components if it has more than exactly two different factors.

If the discount rate is 4%,the present value of the savings account is $5,448.50.

From the question above, :Savings amount = $7,942

Discount rate = 4%

Time period = 9 years

We need to calculate the present value of the savings account.To calculate the present value, we will use the formula,PV = FV / (1 + r)n

Where,PV = Present value of savings account

FV = Future value of savings account

r = discount rate, and

n = Time period

In this problem,PV = ?

FV = $7,942

r = 4%

n = 9 years

Substitute the values in the formula,

PV = 7,942 / (1 + 0.04)9

PV = $5,448.50

Therefore, the present value of the savings account is $5,448.50.

When the histogram of a given income distribution is positively skewed that means mean is larger than median.

When the histogram of a given income distribution is positively skewed, it implies that the tail of the distribution is longer on the right side, indicating that there are a few high-income outliers that pull the mean towards the right side.

As a result, the mean of the distribution will be greater than the median. The median, on the other hand, is the middle value of the data set when arranged in order from lowest to highest, and it is less influenced by outliers than the mean.

Therefore, the median will be closer to the center of the distribution and likely to be smaller than the mean in a positively skewed income distribution.

Step-by-step explanation:

Divide 712 hours by 24 hours/day, obtaining 29 2/3 days, which in turn breaks down into 28 days plus 1 2/3 days, or 4 weeks plus 1 2/3 days.  '4 weeks' takes us to a Monday, 22:48, 4 weeks after the start of the journey.

To this we add 1 2/3 days, reaching 16 hours into the Tuesday immediately following that Monday.  That would be approximately 16:00 on that Tuesday, but we must work backwards 1:12 hours:  subtracting 1:12 from 16:00 on Tuesday yields 14:48

The journey finishes at 14:48 4 weeks and 1 day after it began.

Answer:

To compare who saves the most of their salary each month among Amy, John, and Emily, we need to calculate the amount of salary each person saves.

Let's assume that the monthly salary of each person is 'S'. Then we can calculate the amount saved by each person as follows:

Amy:

Amount saved = 20% of S = 0.2S

Amount spent = S - 0.2S = 0.8S

John:

Amount spent = 2/5 of S = (2/5)S

Amount saved = S - (2/5)S = (3/5)S

Emily:

Let's assume that Emily saves '5x' and spends '8x' of her monthly salary.

Then, according to the question, we have:

Amount saved = 5x

Amount spent = 8x

We know that the ratio of the amount saved to the amount spent is 5:8, so we can write:

Amount saved / Amount spent = 5/8

Substituting the values of amount saved and amount spent, we get:

5x / 8x = 5/8

5x = (5/8) x 8x

5x = 5x

Therefore, the ratio of amount saved to amount spent is equal to 5:8. This means that Emily saves 5/13 of her monthly salary and spends 8/13 of her monthly salary.

So, the amount saved by each person is:

Amy: 0.2S

John: (3/5)S

Emily: 5/13 of S

Now, we need to compare these amounts to find out who saves the most.

To compare these amounts, we can write them in terms of a common denominator:

Amy: 0.2S

John: (3/5)S = (0.6)S

Emily: (5/13)S = (0.3846)S (approx.)

Therefore, we see that John saves the most of his salary each month, followed by Amy and then Emily.

Working out:

Let's assume that each person earns $1000 per month.

Amy:

Amount saved = 20% of $1000 = $200

Amount spent = $800

John:

Amount spent = 2/5 of $1000 = $400

Amount saved = $1000 - $400 = $600

Emily:

Let's assume that Emily saves $5x and spends $8x of her monthly salary.

Then, we have:

Amount saved = $5x

Amount spent = $8x

We know that the ratio of the amount saved to the amount spent is 5:8, so we can write:

$5x / $8x = 5/8

Solving for x, we get:

x = 8/13

Substituting the value of x, we get:

Amount saved = $5 x (8/13) x $1000 = $384.62 (approx.)

Amount spent = $8 x (8/13) x $1000 = $615.38 (approx.)

Therefore, we see that John saves the most of his salary each month, followed by Amy and then Emily.

Answer:

687.5

Step-by-step explanation:

The product of 56.2 and 9.2057 to the appropriate number of significant digits is 517.00.

The significant digits in a number are the digits that contribute to its precision. When multiplying numbers, the result should be rounded to the same number of significant digits as the factor with the least number of significant digits.

In this case, 56.2 has three significant digits, and 9.2057 has five significant digits. The factor with the least number of significant digits is 56.2. Therefore, the product should be rounded to three significant digits.

Multiplying 56.2 by 9.2057 gives 517.38134. Rounding this result to three significant digits gives us 517.00. The trailing zeros after the decimal point are significant in this case as they indicate the precision of the result. Hence, the correct answer is 517.00.
