Answer:

8

Step-by-step explanation:

AB is 3 cm and AC is 2 cm, and since triangle ABC is an isosceles triangle, BC can either be 3 cm or 2 cm. We want the longest perimeter possible, so make BC 3 cm, and add the side lengths to find the perimeter.

P = 3 + 3 + 2 = 8.

Answer:

\( \sf { 55.25}\)

Step-by-step explanation:

Step 1: Find the percentage price of calculator = $65 × 15%

\( = \frac{65}{1} \times \frac{15}{100} \)

\( = 65 \times 0.15\)

\( = 9.75\)

Step 2: Substract the price of the percentage from the price of the calculator

\( = 65 - 9.75\)

\( = 55.25\)

So, Kaylee will pay $55.25 for the calculator after the 15% discount

If she follows the path shown by the dotted line in the graph, the distance from her house to the store would be = 128m. That is option B.

To calculate the distance between her house and the store the Pythagorean formula should be used which is given as follows;

C² = a² + b²

where;

a= 80

b= 100

c= ?

That is;

c²= 80²+100²

= 6400+10000

= 16,400

c = √16400

= 128.1m

The dimensions of the rhombus are given below.

Since H is the center of the rhombus, all sides are equal in length.

Let x be the length of each side. Then, we can use the Pythagorean theorem to solve for x:

DE = (EF/2)^2 + (DF/2)^2

DE² = (13/2)^2 + (18/2)^2

DE² = 169/4 + 324/4

DE² = 123.25

DE = sqrt(493)/2

Since DEFG is a rhombus, all sides are equal in length. Thus, we have:

EF = FG = 13

FG = GH = DE = 11.10

GH = HE = EF = 13

Therefore, the dimensions of the rhombus are:

DE = FG = GH = HE = 11.10

EF = DF = 13 and 18, respectively.

Step-by-step explanation:

4( c - 3 ) = 8

you can either distribute the 4 which means multiply whats inside of the parenthesis by 4 , 4 * c = 4c and 4 * -3 = -12 to get 4c - 12 = 8

or you can divide both sides by 4 which will get you c - 3 = 2

4(c-3)/4 = c - 3

8/4 = 2

a. To estimate the percentage of homes selling for more than $500,000 and analyze the normality of the price distribution, we use the mean and standard deviation provided. Additionally, we compare the expected number of homes with prices greater than the mean to the actual number. A frequency distribution of prices can also provide insights.

b. For estimating the number of homes on the market for more than 24 days and assessing the normality of the days on the market distribution, we utilize the mean and standard deviation given. We compare the expected number of homes with more than the mean days on the market to the actual number. A frequency distribution of days on the market can help in understanding the distribution pattern.
a. To estimate the percentage of homes selling for more than $500,000, we need to calculate the area under the normal distribution curve beyond $500,000 using the mean ($357,000) and standard deviation ($160,700). We can then compare this estimate to the actual results to assess the normality of the price distribution. Additionally, by comparing the expected number of homes with prices greater than the mean to the actual number, we can evaluate the distribution's fit. Constructing a frequency distribution of prices can reveal patterns or skewness.
b. To estimate the number of homes on the market for more than 24 days, we can use the mean (30 days) and standard deviation (10 days) with the normal distribution. Comparing this estimate to the actual results helps assess the normality of the days on the market distribution. Furthermore, by comparing the expected number of homes with more than the mean days on the market to the actual number, we can evaluate the approximation. Constructing a frequency distribution of days on the market can provide insights into the distribution's shape and characteristics.
Note: The actual results and observations from the frequency distributions will depend on the specific data and its distribution pattern.

The function h(x) = (x^2 + 3x - 10) / (x + 5) has a hole at x = -5 because it can be simplified by canceling out the common factor of x + 5 in both the numerator and denominator.

When x = -5, the denominator becomes zero, resulting in an undefined value for h(x).

However, by canceling out the common factor, we can simplify the function to h(x) = x - 2, which is defined and continuous at x = -5.

This indicates that there is a hole in the graph of h(x) at x = -5, where the function is undefined but can be "filled" by the simplified form.

On the other hand, the function g(x) = (3x - 2) / (x + 5) does not have a hole at x = -5 but rather has a vertical asymptote.

This is because even though both h(x) and g(x) have x + 5 as the denominator, the numerator of g(x) does not contain a common factor with the denominator that can be canceled out.

Therefore, when x = -5, g(x) is undefined due to division by zero. As x approaches -5 from either side, the denominator becomes arbitrarily close to zero, resulting in a vertical asymptote at x = -5.

This means that the graph of g(x) approaches infinity or negative infinity as x approaches -5, but the function is undefined at x = -5 itself.

In summary, the presence of a common factor between the numerator and denominator allows for cancellation and the creation of a hole in the graph of h(x) at x = -5.

In contrast, when there is no common factor to cancel, the function g(x) has a vertical asymptote at x = -5 due to division by zero.

The measure of this angle in degrees is 20.52 degrees.

Step by step explanation:Given data is,1/360th of the circumference of the circle is 0.59 cm long Arc length, s = 103.25 cm We need to find the measure of the angle in degrees. Since we know that, the angle subtended by an arc at the center of the circle is 2θ, where θ is the angle subtended by the arc at any point on the circumference of the circle.And the circumference of the circle is 360θ.

Hence, we can find the length of the circumference of the circle. Circumference of the circle = 360 × 0.59Circumference of the circle = 212.4 cmNow, we can find the radius of the circle.r = s/2πr = 103.25/(2 × π) = 16.441 cmDiameter of the circle = 2 × rDiameter of the circle = 32.882 cmThe circumference of the circle = πdCircumference of the circle = π × 32.882Circumference of the circle = 103.26 cm Now, we can find the angle of the circle. Angle of the circle = 360θ103.26 = 360θθ = 103.26/360θ = 0.286 degrees So, the measure of this angle in degrees is 20.52 degrees.

The reciprocal of the fraction 1/2π is 2π. To find the reciprocal of a fraction, we need to flip the numerator and denominator. In this case, we have the fraction 1/2π.

To find its reciprocal, we need to invert the fraction, which gives us π/2. However, if we want to simplify the reciprocal, we can multiply both the numerator and denominator by 2 to get 2π/4, which further simplifies to π/2. Thus, the reciprocal of 1/2π is 2π. In general, to find the reciprocal of any fraction a/b, we simply need to swap the numerator and denominator, resulting in the fraction b/a.

Step-by-step explanation:

On the map, the two cell towers are 6 centimeters away from each other.

In real life, the two cell towers are 3 kilometers away from each other.

To find the scale of the map, we have to find the ratio of the distance between to two cell towers on the map and in real life.

Let us put both distance in the same unit, centimeters:

1 kilometer  = 100000 centimeters

3 kilometers = 3 * 100000 centimeters = 300000 centimeters

Therefore, the ratio of both distances is:

6 : 300000

In lowest terms:
