Calculate the perimeter of the irregular shape please show ur work Bc I have too !!

Answer:

Step-by-step explanation:

Find the value of s on one side of the equation to isolate it.

1.1=s+2.3/3

First, switch sides.

\(\sf{\dfrac{s+2.3}{3}=1.1}\)

Multiply by 3 from both sides.

\(\sf{\dfrac{3\left(s+2.3\right)}{3}=1.1* \:3}\)

Solve.

1.1*3=3.3

s+2.3=3.3

Then, subtract by 2.3 from both sides.

s+2.3-2.3=3.3-2.3

Solve.

Subtract.

3.3-2.3=1.0=1

s=1

Therefore, the final answer is s=1.

Answer: Each dog costs $50 and each cat costs $20

Step-by-step explanation:

You literally put the answer in your question.

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get \(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

Let's consider that s be the length of a side of the regular pentagon.

The perimeter of the regular pentagon will be 5s. Therefore, we have the equation:5s = 140s = 28 cm

Also,

we have the formula for the area of a regular pentagon as:

\($A=\frac{1}{4}(5 +\sqrt{5})a^{2}$,\)

where a is the length of a side of the pentagon.

In order to represent the area of a regular pentagon whose perimeter is 140 cm, we need to substitute a with s, which we have already calculated.

Therefore, we have:\(A(s) = $\frac{1}{{4}(5 +\sqrt{5})s^{2}}$\)

Now, we have successfully used function notation (with the appropriate functions above) to represent the area of a regular pentagon whose perimeter is 140 cm.

The area of a regular pentagon can be represented using function notation (with the appropriate functions above). The first step is to calculate the length of a side of the regular pentagon by dividing the perimeter by 5, since there are 5 sides in a pentagon.

In this case, we are given that the perimeter is 140 cm, so we get 5s = 140, which simplifies to s = 28 cm. We can now use the formula for the area of a regular pentagon, which is\(A = (1/4)(5 + sqrt(5))a^2\), where a is the length of a side of the pentagon.

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get\(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

The area being measured will not match the Riemann sum. By employing ever smaller forms to divide the area more precisely, this mistake can be minimized. The sum approaches the area as the shapes become ever-smaller.

A specific type of approximation of an integral by a finite sum in mathematics is known as a Riemann sum. It bears the name of the German mathematician Bernhard Riemann from the nineteenth century. Approximating the area of functions or lines on a graph, as well as the length of curves and other approximations, is a highly typical use.

The point on the x-axis where the magnetic field is zero when the two currents are in the same direction is midway between the two wires.

The magnetic field produced by a current-carrying wire is directly proportional to the distance from the wire. When two current-carrying wires are placed parallel to each other and the current is in the same direction, the magnetic fields around them combine to produce a magnetic field that cancels out at the midpoint between the two wires. Therefore, the point on the x-axis where the magnetic field is zero is the midway point between the two wires, and this point can be calculated using the distance formula. The appropriate units for this point are the same as the units used for the distance between the wires.

The value of x in this scenario is 14 feet. This can be determined by using the formula for the area of a rectangle and the given information about the length and width of the swimming pool.

The formula for the area of a rectangle is A = length × width. In this case, we are given that the area is 240 sq ft and the length is 10 ft. Let's substitute these values into the formula: 240 = 10 × (x - 2).

To solve for x, we need to isolate it on one side of the equation. We divide both sides of the equation by 10: 240/10 = x - 2. Simplifying, we get 24 = x - 2.

To isolate x, we add 2 to both sides of the equation: 24 + 2 = x. This yields x = 26.

Therefore, the value of x is 14 feet, as obtained by solving the equation x - 2 = 14.

The amount you will pay back by the end of the term is; 162.18 dollar.

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

\(a = p(1 + r)^{t}\)

Given that you borrow $101 at 7% compounded annually for seven years, then we have;

P = 101 dollar

Rate = 7%

Therefore,

\(a = p(1 + r)^{t}\)

Answer:

The first option, incase something happens to the president, they’re next in line.

Step-by-step explanation:

\(10 - d = - 34 - 5d\)

Because we cannot subtract or add up constants and variables, we simply move the same variable term to the same side and constant term to the same constant side.

\(10 + 34 = - 5d + d \\ 44 = - 4d \\ \frac{44}{ - 4} = d \\ - 11 = d\)

Substitute d = -11 in the equation.

\(10 - ( - 11) = - 34 - 5( - 11) \\ 10 + 11 = - 34 + 55 \\ 21 = 21\)

The probability that more than 38% of the people in the sample of 65 adults have high blood pressure is approximately 0.0453, or 4.53%.

To calculate the probability, we can use the normal approximation to the binomial distribution. Given that the sample size is 65, we can assume that the number of adults with high blood pressure in the sample follows a binomial distribution with parameters n = 65 (sample size) and p = 0.38 (probability of an adult having high blood pressure).

First, we need to find the mean (μ) and standard deviation (σ) of this binomial distribution:

μ = n * p = 65 * 0.38 = 24.7

σ = sqrt(n * p * (1 - p)) = sqrt(65 * 0.38 * (1 - 0.38)) = 4.71

Next, we need to find the z-score for the desired probability. To find the z-score, we subtract the mean from the desired value and divide by the standard deviation:

z = (x - μ) / σ = (x - 24.7) / 4.71

Since we are interested in finding the probability of more than 38% (0.38) of the people having high blood pressure, we want to find the probability of x > 0.38 * 65 = 24.7. Therefore, the z-score becomes:

z = (24.7 - 24.7) / 4.71 = 0

Using a standard normal distribution table or calculator, we can find the probability corresponding to a z-score of 0 is 0.5. However, since we are interested in the probability of more than 38%, we need to find the area under the curve beyond the z-score of 0.5, which is 1 - 0.5 = 0.5.

The probability that more than 38% of the people in the sample of 65 adults have high blood pressure is approximately 0.0453 or 4.53%. This implies that there is a relatively low chance of observing such a high proportion of individuals with high blood pressure in the given sample.

Answer:

25°

Step-by-step explanation:

Since ∠DBC = 130°, ∠DBC + ∠ABD = 180° (sum of angles on a straight line is 180°). Solving for ∠ABD:

∠DBC + ∠ABD = 180°

130 + ∠ABD  = 180°

∠ABD = 180° - 130°

∠ABD = 50°

∠ABD  is bisected by line BE, therefore ∠ABD = ∠EBA + ∠DBE (angle addition postulate).

The angle addition postulate states that if w is the interior of xyz then ∠XYZ = ∠XYW + ∠ZYW

Since E is the interior of ∠ABD, then:

∠ABD = ∠EBA + ∠DBE

But ∠EBA = ∠DBE

∠ABD = 2∠EBA

50 = 2∠EBA

∠EBA = 25°

The resulting expression if the value of t is 23 is g(23) = -4g - 207

A function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given the function below;

g(t)=−9t−4g

We are to determine the value of g(23). Substitute t = 23;

g(t)=−9t−4g

g(23) = -9(23) - 4g

g(23) = -207 - 4g

g(23) = -4g - 207
