The perimeter of the square garden is 36 feet, which means that each side of the square is 36/4 = 9 feet long. Therefore, the total cost of the fences is $92.

The length of the outer fence, which is 2 feet away from the garden, is equal to the perimeter of a larger square with sides that are 2 feet longer than the sides of the original garden.

So, the length of the outer fence is 4(9+2) = 44 feet.

The length of the inner fence, which is around the perimeter of the garden, is equal to the perimeter of the original square garden, which is 4(9) = 36 feet.

The total length of both fences is the sum of the lengths of the inner and outer fences:

36 + 44 = 80 feet.

The cost of the fences is the total length of both fences multiplied by the cost per foot:

80 x $1.15 = $92.

Therefore, the total cost of the fences is $92.

Any value between 5.3 cm and 11.7 cm (exclusive) could be the length of the third side of the triangle which is 6.7cm in the given options.

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words, for a triangle with sides a, b, and c, where c is the longest side, the following inequality holds:

a + b > c

This means that the length of any side of a triangle must be less than the sum of the lengths of the other two sides. This theorem is fundamental in geometry and is used in many proofs and applications.

According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, the length of the third side must be greater than the difference between the other two sides and less than their sum.

Let's apply this rule to the given triangle. We have two sides of length 3.2 cm and 8.5 cm.

To be a valid triangle, the length of the third side must satisfy the following inequality:

8.5 cm - 3.2 cm < third side < 8.5 cm + 3.2 cm

5.3 cm < third side < 11.7 cm

Therefore, any value between 5.3 cm and 11.7 cm (exclusive) could be the length of the third side of the triangle. So it's 6.7cm.

The solution of the system of equations is x = -5/17 and y = -16/17.

To do this, we can use a method called substitution. In this method, we solve one equation for one variable in terms of the other variable, and then substitute this expression into the other equation. This results in a new equation with only one variable, which can be solved to find the value of that variable. Once we know the value of one variable, we can substitute it into either equation to find the value of the other variable.

Let's apply this method to your system of equations:

5x - y/2 = -1 (Equation 1)

3x - 2y = 1 (Equation 2)

First, we'll solve Equation 1 for y in terms of x:

5x - y/2 = -1

y/2 = 5x + 1 (Add y/2 to both sides)

y = 10x + 2 (Multiply both sides by 2)

Now we substitute this expression for y into Equation 2:

3x - 2(10x + 2) = 1 (Substitute y = 10x + 2)

3x - 20x - 4 = 1

-17x = 5

x = -5/17

Now that we know the value of x, we can substitute it into either Equation 1 or Equation 2 to find the value of y. Let's use Equation 1:

5x - y/2 = -1

5(-5/17) - y/2 = -1

-25/17 - y/2 = -1

y/2 = -1 + 25/17

y/2 = -8/17

y = -16/17

The number of scoops of seeds needed to fill three bird feeders is 13 1/7 scoops of seeds .

To calculate the total seed quantity required to fill all three feeders, begin by computing the volume for the first two dispensers: each can hold 5 and five-twelfths cups of seeds.

Next, this text assumes an understanding that one scoop of seeds holds approximately 1 and one-sixth cups of product. Using this information, we determine how many scoops are needed to satisfy all three bird feeders' capacity.

By multiplying the first fraction's value with the reciprocal of the second fraction helps you divide fractions accurately:

(46 / 3) x (6 / 7) = (46 x 6) / (3 x 7) = 276 / 21

276 / 21 = 13 3/21

Answer:

55

Step-by-step explanation:

The first we need to do is find the other angle measures. The left angle must be supplementary with 110, so it must measure 70. The right angle must be supplementary with 125, so it must measure 55. The sides of an angle add up to 180, so 180-70-55= 55

The angle of x is 55°.

There is 180° in a triangle. First, we need to calculate the angles of the other two sides. A straight line also forms 180°. Therefore the first angle will be

180 - 110= 70°

The second angle will be

180 - 125 = 55°

Angles of the triangle excluding x will be

70 + 55  =  125°

Since there is 180° in a triangle, x will be

180 - 125=  55°

The account's effective annual yield if you invest $1800 and it pays 6.3% interest compounded daily, is calculated as: 6.53%.

In order to find the effective annual yield of an account, the formula to apply is expressed as:

Effective annual yield = (1 + r/n)^n - 1

where:

r represents the annual interest rate (as a decimal)

n represents the number of times the interest is compounded per year

In this case, we are given the following:

Annual interest rate = 6.3% = 0.063

The interest is compounded daily, so n = 365 (days in a year)

Frank used a total of 2 14/15 gallons of gas on Saturday and Sunday combined.

To find the total amount of gas Frank used on both days, we need to add the amount of gas he used on Saturday and Sunday.

First, we need to make sure that both quantities are in the same form. We can convert the mixed number 2 1/3 to an improper fraction by multiplying the whole number by the denominator and adding the numerator. This gives us:

2 1/3 = (2 x 3 + 1)/3 = 7/3

Next, we can add the two quantities by finding a common denominator. The lowest common denominator for 3 and 5 is 15. So, we can write:

7/3 gallons + 3 2/5 gallons = (35/15 + 9/15) gallons

= 44/15 gallons

To simplify the answer, we can express the mixed number as a whole number and a proper fraction by dividing the numerator by the denominator. This gives us:

The measure of angle x is  23⁰.

The value of arc angle y is 45.5⁰.

The value of arc angle z is 116⁰.

The measure of angle x, y and z is calculated as follows;

∠mEGF = ¹/₂ (arc EF - arc DC ) (intersecting chord theorem)

33 = ¹/₂ (89 - x )

2(33) = 89 - x

66 = 89 - x

x = 89 - 66

x = 23⁰

The value of arc angle z is calculated as follows;

89 + 132 + 23 + z = 360 (sum of angles of a circle)

244 + z = 360

z = 360 - 244

z = 116⁰

The value of angle y is calculated as follows;

∠mGEF = ¹/₂(z) (intersecting chord theorem)

∠mGEF =  ¹/₂(116)

∠mGEF = 58⁰

∠mEFG = 180 - (58 + 33) = 89

y + 89 + y = 180 (sum of angles on a straight line)

Under the premise that the null hypothesis is true, the p-value is the likelihood of witnessing a test statistic that is as severe as the one computed or even more extreme. The p-value of a right-tailed test is the likelihood of seeing a test statistic that is higher than or equal to the computed test statistic.

We can compare the test statistic to the critical value or use a conventional normal distribution table to calculate the p-value given that the test statistic is z = 0.52 and the significance threshold is 0.05

Looking up the p-value corresponding to z = 0.52 in a standard normal distribution table or using a calculator, we find that the p-value is approximately 0.3015.
