The perimeter of a rectangle is 34 units. Its width is 6.5 units.
Write an equation to determine the length (t) of the rectangle.
Find the length of the rectangle.

Answer:

Average speed = Total distance ÷ Total time

Average speed = 16250 km ÷ 10 days = 1625 km/day

1 km = 1000 m

1625 km = 1625 × 1000 m = 1,625,000 m

1 day = 24 hours = 24 × 60 minutes = 1440 minutes

10 days = 10 × 1440 minutes = 14400 minutes

Average speed = 1,625,000 m ÷ 14400 minutes = 113.19 m/min

1 minute = 60 seconds

Average speed = 113.19 m/min ÷ 60 seconds/min = 1.8865 m/s.

The measures of the smallest and the largest possible integral lengths of the third side of the triangle is 21 and 1 respectively

What is Triangle?

A triangle is a three-edged polygon with three vertices. It is a fundamental shape in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.

A side of a triangle must be always less than or equal to the sum of other two sides and greater than the difference of other two sides.

Say the required side is x.

So x<9+11 and x>9-11

So 20<x<2

So the smallest integer is 21 and the largest integer is 1

The number of students is the cost of the trip the same at each museum is 25

When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.

 y = 75 +7x . . . . . cost for x students to visit the science center

 y = 50 +8x . . . . cost for x students to visit the natural history museum

Subtracting the first equation from the second, we get

 0 = -25 +x

 25 = x . . . . . add 25; the number of students such that costs are equal

The cost will be the same either place for 25 students.

Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is

 $25/($1 /student) = 25 students.

This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

Using mathematical expressions, for the cost of the trip to be the same at each museum, the number of students must be 5.

Mathematical expressions combine variables, constants or numbers, and mathematical operators., without the equation or inequality symbols.

                          Science Center   History Museum

Cost per student       $8                           $5

Fixed cost                  $5                         $20

Let the number of students = x

The total cost at the Science Center = 5 + 8x

The total cost at the History Museum = 20 + 5x

For the cost to be the same at either center:

5 + 8x = 20 + 5x

The confidence interval can be expressed as (27.4%, 38.0%).

This confidence interval can be calculated using the formula (X ± z*σ/√n), where X is the sample mean, z is the z-score that corresponds to the desired confidence level (in this case, 95%), σ is the population standard deviation, and n is the sample size.

This is calculated using the formula:

lower bound = point estimate - margin of error and

upper bound = point estimate + margin of error.

In this case, the point estimate is 33.2% and the margin of error is 5.8%.

Therefore, lower bound = 33.2% - 5.8% = 27.4% and

upper bound = 33.2% + 5.8% = 38.0%.

This means that we are 95% confidence interval that the true population proportion lies between 27.4% and 38.0%.

Thus, the response is: B) The pavement becomes the new surface (and Earth).

The law of conservation of momentum states that an object's momentum may only be transferred, not created or destroyed, and is equal to its mass times its velocity.

The momentum the car (and its contents) had before braking must go somewhere when it skids to a halt. The friction force between the tyres and the road in this instance causes it to be transferred to the pavement (and Earth). The friction force slows the car down until it comes to a stop by acting in the opposite direction of the car's speed.

The length of the diagonal of the rectangle is 41 units.

To find the length of a diagonal of a rectangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

In this case, the rectangle is the right triangle, and the lengths of the two shorter sides are 9 and 40 units. So we can write the equation:

9² + 40² = d²

Expanding both sides:

81 + 1600 = d²

Adding the two sides:

1681 = d²

Taking the square root of both sides:

d = 41 units

Variance is a measure of dispersion that considers the spread of all data points in a data collection, in contrast to range and interquartile range. The standard deviation, which is just the square root of the variance, is the other often used measure of dispersion.

A measure of variability is the variance. It is determined by averaging the squared deviations from the mean. Your data set's variability is shown by its variance. The variance is greater in respect to the mean when the data are more dispersed.

Since the data are stated in the question to be evenly distributed, the mean will be determined using the formula.

Mean = a + b /2

Where, a be the minimum value and b be the maximum value

for the data: 0.15,0.16,0.17,0.18, and 0.19

The value of a = 0.15 and b = 0.19

Substitute the values in the above equation, we get

Mean = (0.15 + 0.19) /2

simplifying the above equation, we get

Mean = 0.34/2

Mean = 0.17

Therefore, the mean of the given data be 0.17.

The sailor is 10 meters above the water and the lighthouse is 40 meters tall, so the total height between the two is 50 meters. Therefore, the sailor will first see the lighthouse from 50 meters away.

Assuming the lighthouse is directly in front of the sailor, the light from the lighthouse will reach the sailor first when the total distance between them is 50 meters. This means the sailor will first see the lighthouse from 50 meters away. In addition, the angle between the sailor and the lighthouse will be equal to the angle of the light when it reaches the sailor's eyes. The angle of the light will depend on the curvature of the earth, the height of the lighthouse, and the height of the sailor.

Assuming the lighthouse is at sea level, the angle of the light when it reaches the sailor's eyes can be calculated using the following equation:

Angle

= arcsin (50 / (2 * 6371))

Where 6371 is the radius of the earth in km.

This calculation gives an angle of 0.0058°. This means the light from the lighthouse will reach the sailor from a distance of 50 meters with an angle of 0.0058°.

The side lengths of the real object will be 175 in, 150 in, and 75 in, respectively.

To determine the side lengths of the real object, we need to use the given scale factor and the side lengths of the scale drawing. The scale factor given is 5:1, which tells us that the scale drawing is 5 times smaller than the real object. Therefore, we can use this ratio to determine the side lengths of the real object. For example, if the side length of the scale drawing is 35 in, then the side length of the real object will be 5 times larger, which is 175 in. We can use this same ratio for the other side lengths of the scale drawing. The side length of the scale drawing is 30 in, so the side length of the real object will be 150 in. The side length of the scale drawing is 15 in, so the side length of the real object will be 75 in. Therefore, the side lengths of the real object will be 175 in, 150 in, and 75 in, respectively.

What is Reflectional Symmetry ?

Any symmetry with regard to a reflection is referred to as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. In other words, a figure with reflectional symmetry does not alter when it is reflected. There is a line/axis of symmetry in 2D and a plane of symmetry in 3D. When a form or pattern is mirrored in a line of symmetry or a mirror line, this is known as reflective symmetry. The reflected form will have the same size, distance from the mirror line, and other characteristics as the original shape. When a figure can be split into two equal halves that match, it has line symmetry or reflection symmetry.

If a figure can be reflected over a line and retain its original appearance, it possesses reflection symmetry. If a figure can be altered while maintaining its appearance, it possesses symmetry.
