Answer:
1.478 x 10^2 AU
Step-by-step explanation:
To convert this distance to astronomical units (AU), we can use the fact that 1 AU is approximately equal to 93 million miles.
So, 13.8 billion miles is approximately:
13.8 billion miles / 93 million miles/AU = 147.8 AU
In scientific notation, this distance would be written as: 1.478 x 10^2 AU

A door frame that appears to be rectangular has a height of 213 cm, width of 92 cm, and one diagonal that measures 231 cm. Determine if the door frame is rectangular. Explain your thinking.
The door frame is not rectangular.
Is the door frame rectangular?If the door frame is rectangular, the sum of the square of the height and the width would be equal to the square of the diagonal.
Height² + width = diagonal²
213² + 92²
45,369 + 8,463 = 53,833
231² = 53,361
53,833 ≠ 53,361
The door frame is not rectangular because the sum of the height and the width is not equal to the diagonal.

find the volume v of the described solid s. the base of s is the triangular region with vertices (0, 0), (5, 0), and (0, 5). cross-sections perpendicular to the x-axis are squares.
Using the disk method, it can be concluded that the volume of the solid is 125π /3 cubic units.
Disk Method is a method used to determine the volume of a solid formed by revolving the region about the x-axis and the interval [a, b]. The volume of the solid is the integral of the area of the base times dx.
V = π ∫ Ax dx
From the question, we know that the base of the figure is a triangular region and the coordinates are (0,0), (5,0), and (0,5).
The square is perpendicular to the x-axis. Thus, we can find the side of the square, that is the straight line passing through (5,0) and (0,5) which meet the y = mx + b equation.
First, we determine the slope of the line (m).
m = (y₂ - y₁) / (x₂ - x₁)
= ( 5 - 0 ) / ( 0 - 5 )
= 5 / -5
= -1
To find b, we input the value of m into the equation for point (5,0):
y = mx + b
0 = -1*5 + b
0 = -5 + b
b = 5
So we got the side of the square:
y = mx + b
y = -x + 5
y = 5 - x
Thus the area of the square is:
A = side²
= (5 - x)²
= 25 + x² - 10x
The volume of the solid can be calculated as follows:
V = π ∫ Ax dx
= π ∫₀² (25 + x² - 10x) dx
= π (25x + 1/3x³ - 5x² |₀⁵)
= π (25*5 + 1/3*5³ - 5*5² - 0)
= π (125 + 125/3 - 125 - 0)
= 125π /3 cubic units
Thus, the volume of the solid is 125π /3 cubic units

a) Write an equation using the information as it is given above that can be solved to answer this question.
Use t as your variable to represent the amount of time Krystal spent driving from Houston to Philadelphia.
Equation:
b) How many miles is Houston from Philadelphia?
Answer:
miles
Give your answer to the nearest mile
Answer: a. The equation using the information as it is given above that can be solved to answer this question is:
distance = speed x time
Let t be the amount of time Krystal spent driving from Houston to Philadelphia.
distance = 50t + 60(46 - 25 - t)
b. To find the distance between Houston and Philadelphia, we can substitute the known values into the equation and solve for t.
distance = 50t + 60(46 - 25 - t)
distance = 50t + 60(21) - 60t
distance = 50t + 1260 - 60t
distance = -10t + 1260
To find the total distance, we can set t = 25
distance = -10(25) + 1260
distance = -250 + 1260
distance = 1010
Therefore, Houston is 1010 miles from Philadelphia, to the nearest mile.

A compound event is a combination of multiple simple events that can occur simultaneously or independently. When talking about coin flipping, the sample space is the set of all possible outcomes of the experiment, which in this case is flipping a coin 3 times. In this case, the sample space is {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}.
Option A, You get exactly 2 tails, is a compound event because it consists of three simple events, THT, HTH, and TTH. These events can happen independently of one another and therefore, it is a compound event.
Option B, You get exactly 3 tails, is not a compound event because it only consists of one simple event, TTT. This event is not a combination of other simple events and is, therefore, not a compound event.
Option C, This is not an event, is not a valid option as it is not a possible outcome.
Option D, You get exactly 3 heads, is also a compound event because it consists of one simple event, HHH. This event can happen independently of other simple events and it is, therefore, a compound event.

What is Confidence Intervals?A confidence interval is a set of values that, given a specific level of certainty, are likely to include a population parameter like a mean or proportion.
The interval is derived using data drawn from a sample of the population and is frequently presented as a range of values with a 95% confidence level.
The probability that the range of values contains the genuine population parameter is quantified by the confidence level.
In the case of a 95% confidence interval, for instance, it means that 95% of the intervals would contain the real population parameter if we sampled the same population more than once and calculated a confidence interval each time.

A rectangle has a length of 8.2cm and a height of 42mm. The area of the rectangle is mm2
Answer: To find the area of a rectangle, you can use the formula:
Area = Length x Height
In this case, the length is given in cm and the height is given in mm. Therefore, you need to convert the length to mm before you can calculate the area.
1cm = 10mm.
So, 8.2 cm = 8.2 x 10 = 82mm
Now you can find the area of the rectangle:
Area = Length x Height = 82mm x 42mm = 3,444 mm^2
So, the area of the rectangle is 3,444 mm^2

An expression using the distributive property to find the earnings Jessica made on Friday and Saturday is 10(4 + 7).
What is distributive property?The distributive property postulates that multiplying the sum of two or more addends by a number gives the same result as multiplying each addend by the number and then adding the products together.
The distributive property helps to solve mathematical expressions written in the form of a(b + c).
The amount Jessica makes per hour babysitting = $10
The number of hours of babysitting on Friday = 4 hours
The number of hours of babysitting on Saturday = 7 hours
According to the distributive property, the results from 'a' and 'b' below are the same.
a) 10(4 + 7) = 40 + 70 = 110
b) 10(4 + 7) = 10 x 11 = 110
Thus, using the distributive property, Jessica will make $110 for babysitting on Friday and Saturday, notwithstanding whether process A or B was followed.

Use the distributive property to write each expression as an equivalent
algebraic expression.
-2(x-4)
Answer:
the equivalent algebraic expression is -2x -8 after applying the distributive property.
Step-by-step explanation:
The distributive property states that for any real numbers a, b, and c, a(b+c) = ab + ac.
To apply the distributive property to the expression -2(x-4), we can distribute the -2 across the parenthesis, like this:
-2(x-4) = -2x + (-2)(-4)
Simplifying the last part of the expression:
-2(x-4) = -2x -8
So, the equivalent algebraic expression is -2x -8 after applying the distributive property.
What is the intersection of y=2x-2 and y= -2x^2 +4x+ 3?
The intersection of equations y=2x-2 and y= -2x^2 +4x+ 3 is y = 3
How to determine the intersection of the linesThe general formula for the equation of a line is expressed as;
y = mx + c
Where the parameters are;
c is the intercept of the line on the y - axism is the slope of the linex is a point on the x-axisy is a point on the y -axisFrom the information given, we have the equation of the lines as;
y=2x-2 y= -2x^2 +5x+ 3Now, equate the lines, we have;
2x - 2 = -2x² + 5x + 3
collect the like terms
2x -5x + 2x² - 2 - 3 = 0
add the iike terms
2x² -3x - 5 = 0
Factorize the quadratic equation
2x² - 5x + 2x - 5 = 0
Group in pairs
(2x² - 5x) + (2x-5) = 0
x(2x -5) + 1(2x - 5) = 0
The intersection for when x = 5/2
y = 2x - 2
y = 2(5/2) - 2
y = 3
Hence, the value is 3
