Answer:

21

Step-by-step explanation:

An isosceles triangle has 2 sides of the same length, those sides being the sides that aren't the base. The perimeter is the total length of all 3 sides of the triangle. We know that the base is 5 inches, and that one side is 8. Because the triangle is isosceles, we know that the others ide is also 8 inches. Therefore, the perimeter is 8+8+5, which is 21.

Answer:

21 in.

Step-by-step explanation:

If the triangle is isosceles, then two of its three sides are of equal length.  We can assume that the side lengths are 5 in., 8 in and 8 in.  Summing these up, we get total length 21 in.  That's the perimeter of the triangle.

In total, Menaha traveled 97km 1000m (97.1km).

Distance is a numerical measurement of how far apart two objects, points, or places are in space. Distance can be measured in linear units such as meters, kilometers, feet, miles, etc. It can also be measured in angular units such as degrees or radians.

Distance can also refer to the space between two points in time, such as the time between two events. Distance can be used to measure physical distance, time, or even emotional distance.
To calculate this, the two distances must be added together.
The train distance is =86km 520m (86.52km)

and the car distance is =11km 480m (11.48km).
When added together, =86km 520m+11km 480m = 97.52km.
However, since the distances are measured in km and m,
it is necessary to convert the measurements into a single unit of measurement.
To do this, the measurements must be converted into metres.
The train distance is 86,520 metres

And the car distance is 11,480 metres.
When added together,

the total distance is 97,000 metres (97km).

The distance between City X and City Y = 440 miles Radius of the Earth, R = 3690 miles Let’s consider two cities X and Y, as shown below. As shown in the figure above, the difference in latitude of the two cities will be the arc length between point P and Q.

So, we need to find the arc PQ, which is the difference in latitude. We have given the distance XY, which is nothing but the chord length. Let’s find the angle subtended by the chord XY at the center of the Earth O. We can find this angle using the formula;angle = (chord length/2*radius of the earth)angle = (440/2*3690) angle

= 0.06 radians Now, we can find the arc PQ by using the formula;arc length PQ = radius of the earth * angle subtended by the chord PQ arc length PQ = 3690 * 0.06 arc length

PQ = 221.4 miles

Therefore, the difference in latitude between City X and City Y is 221.4 miles.

Since the calculated probability is -0.5, none of the provided options (a) 0.7, b) 0.5, c) 0.4, d) 0.3) are correct.

To find the probability of event E = {01, 03} in the given sample space S = {01, 02, 03, 04}, we need to sum the weights of the outcomes in E.

The weights of the outcomes are:

w1 = -0.4, w2 = -0.2, w3 = -0.1, w4 = 0.3

The event E consists of outcomes {01, 03}, so we calculate the probability as:

P(E) = w1 + w3 = -0.4 + (-0.1) = -0.5

Since the calculated probability is -0.5, none of the provided options (a) 0.7, b) 0.5, c) 0.4, d) 0.3) are correct.

It is worth noting that probabilities should be non-negative values between 0 and 1. However, in this case, the calculated probability is negative, which suggests that there may be an error in the given weights or sample space.

None of the given options (a), b), c), d)) are correct for the probability of event E.

The weights of the outcomes in the sample space are:

w1 = -0.4

w2 = -0.2

w3 = -0.1

w4 = 0.3

The weights of the outcomes in event E are:

we1 = -0.4

we3 = -0.1

Now, let's calculate the probability of event E for each given option:

a) 0.7:

The probability would be calculated as:

P(E) = (we1 + we3) / (w1 + w2 + w3 + w4) = (-0.4 - 0.1) / (-0.4 - 0.2 - 0.1 + 0.3) = -0.5 / -0.4 = 1.25

Since the calculated probability is not within the range [0, 1], option a) is not correct.

b) 0.5:

P(E) = (we1 + we3) / (w1 + w2 + w3 + w4) = (-0.4 - 0.1) / (-0.4 - 0.2 - 0.1 + 0.3) = -0.5 / -0.4 = 1.25

Again, the calculated probability is not within the range [0, 1]. Therefore, option b) is not correct.

c) 0.4:

P(E) = (we1 + we3) / (w1 + w2 + w3 + w4) = (-0.4 - 0.1) / (-0.4 - 0.2 - 0.1 + 0.3) = -0.5 / -0.4 = 1.25

The calculated probability is still not within the valid range. Thus, option c) is not correct.

d) 0.3:

P(E) = (we1 + we3) / (w1 + w2 + w3 + w4) = (-0.4 - 0.1) / (-0.4 - 0.2 - 0.1 + 0.3) = -0.5 / -0.4 = 1.25

The calculated probability is not within the range [0, 1]. Therefore, option d) is not correct.

In shape (i), there are two electron domains around the central atom. This means that the electron-domain geometry is linear. However, there are two bonding pairs and no lone pairs of electrons around the central atom, resulting in the molecular geometry also being linear.

The concept of electron-domain geometry and molecular geometry is essential in understanding the properties of molecules. The electron-domain geometry is determined by the number of electron domains (bonding or lone pairs) around the central atom in a molecule. On the other hand, the molecular geometry is determined by the arrangement of atoms in the molecule, taking into account the presence of lone pairs.

Knowing the electron-domain geometry and molecular geometry of a molecule is crucial in predicting its polarity and reactivity. For instance, polar molecules have an asymmetric distribution of electron density, while nonpolar molecules have a symmetric distribution. This difference in polarity affects the physical and chemical properties of a molecule, such as boiling point, melting point, and solubility.

In summary, in shape (i), both the electron-domain geometry and molecular geometry are linear, which means that the central atom has two bonding pairs and no lone pairs. Understanding the electron-domain and molecular geometry of molecules is essential in predicting their properties and behavior.

The slope of function f is - 1 and the y-intercept of f is 4.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Let Two points on the function f are (-1, 5) and (0, 4).

Now,

Since, The equation of line passes through the points (-1, 5) and (0, 4).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (4 - 5) / (0 - (-1))

m = - 1 / 1

m = - 1

Thus, The equation of line with slope - 1 is,

⇒ y - 5 = -1 (x - (-1))

⇒ y - 5 = - 1 (x + 1)

⇒ y = - x - 1 + 5

⇒ y = - x + 4

By comparing with the equation of line y = mx + b, we get;

The y-intercept of f = 4

Two quadrilaterals are similar when there corresponding angles are equal to each other.

Given that;

In figure 1;

Two triangles are shown.

In figure 2;

One rectangle and other is square.

In figure 3;

Two rectangle are shown.

Now,

Since, Two quadrilateral are similar when there corresponding angles are same.

In the figure 1;

The angles of first triangles = 37° , 53°

So, The third angle = 180 - (37 + 53)

                              = 90

The angles of second triangles = 37° , 53°

So, The third angle = 180 - (37 + 53)

                              = 90

Thus, There all angles are equal to each other.

So, These figure are Similar.

And, In figure 2;

One figure is square and other is a rectangle.

So, It is not similar.

And, In figure 3;

Both figure are rectangle.

And, All angles in a rectangle are 90 degree.

Thus, they are similar.

A few properties of a parallelogram.

1) Opposite sides are always equal.

2) Opposite angles are always equal.

3) The sum of all the angles is 360.

In part 2, we are given the angles. Therefore, we can apply the 2nd property.

11x = 55

5y = z (lets say the unknown is z).

Now, 11x = 55

x = 55/11

x = 5

Now, we have to angles of 55 degrees but we don't know about y and z. Therefore, we have to apply the third property.

55 + 55 + 5y + z = 360

110 + 5y + z = 360

5y + z = 360 -110

5y + z = 250. (i)

According to property 2, 5y = z. Hence, put the value of 5y in the equation (i), we get

5y + z = 250

z + z = 250

2z = 250

z = 250/2

z = 125

From the value of z, we can find the value of y using z = 5y

125 = 5y

5y = 125

y = 125/5

y = 25
