350 feet of fencing is needed to Enclose the backyard

To calculate the amount of fencing needed to enclose the backyard, we need to find the length of the three long sections of the fence.

Since the yard has a width of 65 feet and the two short sections of the fence each measure 10 feet, the total width of the yard plus the short sections of the fence is:

65 + 10 + 10 = 85 feet

Next, we need to find the length of the yard plus the two short sections of the fence. Since the length of the yard is 80 feet, and there are two short sections of the fence that are each 10 feet long, the total length of the yard plus the short sections of the fence is:

80 + 10 + 10 = 100 feet

Now we can calculate the length of the three long sections of the fence by adding up the perimeter of the yard plus the short sections of the fence and then subtracting the lengths of the two short sections of the fence:

2(85 + 100) - 2(10) = 350 feet

Therefore, 350 feet of fencing is needed to enclose the backyard.

The greatest common factor is 3x² and GCF form of polynomial is

3x²(3x-2).

The given polynomial is

9x³ - 6x²

We can write it as;

3x²(3x-2)

We know that

The greatest common factor (GCF) that divides two or more numbers is known as the greatest common divisor (GCD). The highest common factor (HCF) is another name for it.

Therefore 3x² is its GCD.

Divide each term of polynomial 3c,

6c³ ÷ 3c = 2c² and  -9c ÷ 3c = -3

Thus,

3x²(3x-2) is the factored version of the polynomial with the highest common factor.

Also if GCD is 1 then after dividing each term by 1 we get same result

The confidence interval based on the given values (x = 45, n = 96, Confidence level = 95%.

The confidence level (95%), sample size (n = 96), and sample mean (x = 45), we can calculate the margin of error and the confidence interval. Here's how:

1. Margin of Error:

The margin of error represents the maximum expected difference between the true population parameter and the sample estimate. It depends on the confidence level and the standard deviation (which we don't have in this case).

Since the standard deviation is unknown, we can use the t-distribution to estimate it. With a sample size of n = 96, the degrees of freedom are (n - 1) = 95. Considering a 95% confidence level, the critical value for a two-tailed test is approximately 1.984 (referencing a t-distribution table or calculator).

The margin of error (E) can be calculated using the following formula:

E = critical value * (standard deviation / sqrt(n))

However, since we don't have the standard deviation, we can't compute the margin of error in this case.

2. Confidence Interval:

The confidence interval represents a range of values within which the true population parameter is likely to fall.

The confidence interval can be calculated using the formula:

CI = x ± (critical value * standard deviation / sqrt(n))

The image of vertex C under the given similarity transformation is (4, 2).

To apply the given similarity transformation, we need to perform two transformations: a rotation of 90 degrees counterclockwise about the origin (denoted by R) and a dilation by a factor of 2 (denoted by D2). We perform the transformations in order: first the rotation, then the dilation.

The image of a point (x, y) after a rotation of 90 degrees counterclockwise about the origin is (-y, x).

Thus, the image of C after the rotation is:

C' = (-(-2), 1) = (2, 1)

To find the image of C' after the dilation by a factor of 2, we multiply each coordinate by 2:

C" = (22, 21) = (4, 2)

Therefore, the image of vertex C under the given similarity transformation is (4, 2).

Answer: n = 412

Step-by-step explanation:

If the last two digits of a number are divisible by 4, the whole number is divisible by 4 since any multiple of 100 is divisible by 4. The largest number that can be created is 421 since the largest number is in the hundreds place and then the second largest number is in the tens place, but 21 is not divisible by 4. The second largest number, 412, still has the greatest number as the hundreds place, but the tens place is now smaller. 12 is divisible by 4, so 412 is divisible by 4. We know that 412 is the largest possible number for n because there is only one larger number than 412, which is 421 and it is not divisible by 4.

Answer:

-----------------------------

Divisibility rule for 4:

We have 3 digits and the greatest number can be made by these digits is 421. But it has to be divisible by 4, hence we rearrange it to 412. Since 12 is divisible by 4, the number is divisible by 4.

Now, we choose 9 as the fourth digit. It will be a first digit from left and form the largest possible number n:

How to compare fractions is explained in the solution below.

One way to compare fractions is to convert them into their decimal form and decide which is the smaller of the two.

Example: 7/10 and 3/5 become 0.7 and 0.6.

Hence 3/5 is smaller than 7/10.

The other way is to convert them into fractions with identical denominator.

For that multiply the denominator of one fraction with the numerator and denominator of the other.

Do the same with the other denominator and the other fraction. Then decide which fraction is the smaller of the two.

Example: 7/8 and 13/15 become (7*15)/(8*15) = 105/120 and

(13*8)/(15*8) = 104/120.

Hence 13/15 is smaller than 7/8.

D. x: 1, 2, 3, 4. y: 0, 6, 16, 30

A linear function has a constant rate of change (slope). Let's calculate the differences in y-values for each table:

A. 1 - 1/2 = 1/2, 1 1/2 - 1 = 1/2, 2 - 1 1/2 = 1/2 (constant differences)

B. 1 - 1/2 = 1/2, 1/2 - 1/3 = 1/6, 1/3 - 1/4 = 1/12 (not constant)

C. 9 - 7 = 2, 13 - 9 = 4, 21 - 13 = 8 (not constant)

D. 6 - 0 = 6, 16 - 6 = 10, 30 - 16 = 14 (not constant)

Table A represents a linear function, as the differences in the y-values are constant (1/2).

The correct answer is B. Wages will increase.

When the Long-Run Aggregate Supply (LRAS) curve begins to slope upward in the second phase, it indicates that as the economy moves towards full employment and productive capacity, wages will increase.

The upward slope of the LRAS curve suggests that as the economy expands and approaches its maximum potential output, the demand for labor increases, leading to higher wages.

This is because firms need to pay higher wages to attract and retain workers in a tightening labor market, where the supply of labor becomes relatively scarce compared to the demand.

To solve the inequality 6(x−1)>−18, we need to isolate x on one side of the inequality. We can do this by dividing both sides of the inequality by 6, but since we're dividing by a negative number, we need to flip the inequality sign:

6(x−1)>−18

x - 1 > -3

Adding 1 to both sides of the inequality gives us:

x > -2

Therefore, the solution to the inequality is x > -2.

Answer: x > -2

Step-by-step explanation:

     To solve the inequality, we will isolate the given variable.

Given:
