what is 375 in inches?
Standard conversions state that 375 cm is equivalent to 147.6 inches.
A fixed magnitude of a quantity that serves as a reference point for measuring other quantities of the same sort is referred to as a unit of measurement. Convention or legislation establish and adopt it. Every other amount of that sort can be expressed as a multiple of the unit of measurement.
One inch is 2.54 cm long.
We can compose,
2.54 cm equals one inch.
1 cm equals 0.54"
Thus, 375 cm will be equal to 375/2.54 inch.

Julie attaches an extension cord that is 2 6/8 yards long to a cord that is 2 3/8 yards long. How long are the two cords together? Select all the correct ways to find the sum
The required two cords together is 5 1/8 yards long, as of the given condition.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
We can add the two cords together in different ways:
2 6/8 yards = 22/8 yards
2 3/8 yards = 19/8 yards
Total length in eighths of a yard: 22/8 + 19/8 = 41/8 yards
Simplifying 41/8 yields 5 1/8 yards.
So the two cords together are either 4 19/36 yards or 5 1/8 yards long.

The Alternate Exterior Angles Theorem states that when a pair of parallel lines is intersected by a transversal, the pairs of alternate exterior angles formed on opposite sides of the transversal are congruent.
If line AB and line CD are parallel, and line EF intersects both lines at points G and H respectively, then the angles formed on opposite sides of line EF and on the exterior of the parallel lines are congruent.
The Alternate Exterior Angles Theorem states that when a pair of parallel lines is intersected by a transversal, the pairs of alternate exterior angles formed on opposite sides of the transversal are congruent.

The product of (3 x 107) and (2 x 107) is 6.8694 x 10^4
To find the product of (3 x 107)and (2 x 107), we can use the distributive property of multiplication which states that the product of a number and a sum is equal to the sum of the products of the number and each term in the sum. In this case, we can multiply the numbers outside the parentheses first, and then multiply the result by the common factor of 107 to simplify the expression:
(3 x 107) x (2 x 107) = 6 x (107 x 107)
Next, we can calculate the product of 107 and 107, which is 11,449:

An angle measures 176.2° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
The angles are 178.1° and 1.9°
Step-by-step explanation:
Supplementary angles add up to 180°
Let the angles be x and y with x being the larger angle
x = 176.2 + y
x - y = 176.2 (1)
Since they add up to 180 we also get
x + y = 180 (2)
Equations added: (1) + (2)
x - y + x + y = 176.2 + 180
2x = 356.2
x = 356.2/2 = 178.1°
y = 180 - 178.1 = 1.9°

school. What is the shortest distance, in miles, between your home and the mall? Round to the nearest hundredth.
Answer: Use the Pythagoream theorem: a²+ b² = c²
Step-by-step explanation: note that c = the hypotenuse
2² + 5² = c²
Simplify
4 + 25 = c^2
Combine like terms
29 = c^2
isolate the c. Root both sides
√29 = c
c = 5.38516481
5.39 is your answer
The shortest distance is 5.39 miles between your home and the mall
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
The distance from your home to the school is 2 miles south, which means the y-coordinate of the school is -2.
The mall is located 5 miles west of the school, which means the x-coordinate of the mall is -5.
So, we have two points on the coordinate plane: your home at (0, 0) and the mall at (-5, -2).
The distance between them can be found using the distance formula:
Distance=√(x₂-x₁)²+(y₂-y₁)²
=Distance=√(-5-0)²+(-2-0)²
=√25+4
=√29
=5.39 units

Using technology, calculate the weighted average ROR of the investments. Round to the nearest tenth of a percent.
The weighted average ROR of the investments, based on the provided investment portfolio, would be 2.1%.
How is a weighted average determined?By multiplying each data point by its weight and adding the resulting products, the weighted average is calculated. The weights for all the data points are then added. Divide the weight*value products by the total weights to finish. You've successfully determined the weighted mean.

yuson thinks the design she made is symmetric across the dashed line she drew. How can she use coordinates to show that her design is symmetric?
She can compare the original design with its reflection by plotting both designs on the same graph. If the two designs are identical, then the design is symmetric across the x-axis.
How to show if her design is symmetricTo show that a design is symmetric across a line using coordinates, you can use the following steps:
Choose the equation of the line that the design is supposed to be symmetric across. Let's assume that the line is the x-axis and it is represented by the equation y = 0.Identify the coordinates of each point in the design. For example, if a point is located at (2, 4), its x-coordinate is 2 and its y-coordinate is 4.Reflect each point in the design across the line of symmetry by changing the sign of its y-coordinate. For example, if a point is located at (2, 4), its reflection across the x-axis is located at (2, -4).Compare the original design with its reflection across the line of symmetry. If the reflected design is identical to the original design, then the design is symmetric across the line.Here's an example of how to use coordinates to show that a design is symmetric across the x-axis:
Suppose Yuson has a design with three points: A(2, 4), B(4, 6), and C(6, 4), and she drew a dashed line along the x-axis to represent the line of symmetry.
To check if the design is symmetric across the x-axis, she can reflect each point across the x-axis to obtain the following new coordinates: A'(2, -4), B'(4, -6), and C'(6, -4).
She can then compare the original design with its reflection by plotting both designs on the same graph. If the two designs are identical, then the design is symmetric across the x-axis.

What is the conversion of 184 cm to feet ?
The conversion of 184 centimetres in feet is equals to the 6.03 feet. Thus, conversion factor from centimetres to feet is 6.03/184 = 0.032.
A conversion factor is a number used to convert one set of units into another set of units by multiplication or division. If conversion is necessary, a conversion factor suitable for equivalent value must be used. For example, to convert meters to centimetres, the appropriate conversion value is 100 centimetres equal 1 meter. It includes converting a value from inches to millimeters, for distance from miles to kilometers, feet or other units. How to convert centimeters to feet : One meter is a measure of length and equals approximately 3.28 feet. Thus conversion factor is 3.28 feet. So, 184meters
= 184× 3.28 feet
= 603.52 feet --(1)
But we need to convert 184 centimeters to feet. So, change meters to centimeters. As you know, 1 meter = 100 centimeters, so 184 meters = 18400 centimeters --(2). Now from equations (1) and (2),
18400 centimeters = 603.52 feet,
Divide both parts by 100,
=> 184 centimetres = (603.52/100 ) feet
= 6.03 feet

We can graph the data in a line graph to visualize the relationship between the two variables. The graph will have time (t) represented on the x-axis and the balance of the savings account (m) represented on the y-axis. The graph will demonstrate that the total balance of the two accounts increases over time.
The equation that models this data can be found by using the slope-intercept form, y = mx + b. Here, y represents the balance of the savings account (m), x represents the time (t), m is the slope of the line, and b is the y-intercept. To find the equation, we can first find the slope, which is the change in y divided by the change in x. This is (2,800 - 500) / (3 - 0) = 2,300 / 3 = 766.67. The y-intercept is the balance of the savings account when t = 0, which is 500. We can now write the equation as m = 766.67x + 500.
