Next, multiply 10.9375 by 0.8 and you get 8.75
Therefore your answer is 8.75
If BC= 6x+6 , AB= 8x+9 , and AC=142 find BC
The value of BC is 60.6.
What exactly is the segment addition property?According to the segment addition postulate, if we have two locations on a line segment, A and C, a third point B lies on the line segment AC if and only if the lengths between the points match the requirements of the equation AB + BC = AC.
Given:
BC = 6x+6
AB = 8x+9
AC = 142
We need to find BC.
As AB and BC combine to form AC, we add them together and equate them with the value of AC to determine the value of x.
Using the property of segment addition,
AB + BC = AC
8x + 9 + 6x + 6 = 142
Combine the variable terms and constants together,
14x + 15 = 142
14x = 142 - 15 (Subtracting both sides by 15)
14x = 127
x = 9.1
Hence the value of BC is,
BC = 6x + 6 = 6(9.1) + 6 = 60.6

Step-by-step explanation:
Prius' acceleration
60 mi/hr = 88 ft s
accel = change in v / change in time = 88 f/s / 10.3 s = 8.54 ft / s^2
F = ma = 2903 * 8.54 = 24802 lb ft/s^2
Now increase the mass to 4903 by adding a 2000 lb trailer (which, by the way is way past the towing capacity of an anemic Prius !)
F = ma
24802 = 4903 a shows a = 5.06 ft/s^2
45 mi/hr = 66 ft/s
a = change in v / change in time
5.06 = 66 / 5.06 = 13 sec

how many ways can you make a 5 digit password that can be any number (including zero) or letter (not case sensitive)? 916132832
These work out to 60,466,176 case insensitive combinations of letters.
There are 10 digits 0–9.
The are 26 letters in the modern alphabets.
However, you didn’t specify whether capital and lowercase letters count as the same letter or separate. In the former case, there are 26 letters, in the latter, there are 52.
There is also such a thing as lowercase numbers, but since they aren’t in common standard usage, I won’t count those.
You also didn’t specify that characters couldn’t be repeated, so I am going to assume that the same character can appear multiple times in a 5 character combination.
Also, since the combinations are an alphanumeric string of characters rather than a number, I will assume that leading zeroes are allowed.
So, there are either 36 (10 digits and 26 letters).
To find the number of combinations you multiply the number of possibilities for each character;
36 x 36 x 36 x 36 x 36
These work out to 60,466,176 case insensitive combinations of letters.

Terms from two sequences are given in tables below. Which of the following statements are true? Select all that apply.
As per the terms from the two sequences given in tables as attachment hereby along with the question statement, the following statements from the provided options are true.
(i) [(a₁) > (g₂)]
(iv) Initially (aₙ) is greater than (gₙ), and as "n" gets larger, (gₙ) is greater than (aₙ).
As per the question statement and the reference tables attached thereby along with the question, we are provided with terms from the two sequences in table format, and five statements based on the sequences.
We are required to determine which statements among the five, are true.
To solve this question, we will use the trial-and-error method, where we will consider individual statement and assess it's honesty.
First statement is [(a₁) > (g₂)], which is true. As we can see from the table, that, [(a₁) = 10] and [(g₂) = 4], i.e., (10 > 4), or, [(a₁) > (g₂)].
Second statement is that, "The constant difference for (aₙ) is 10" which is False. We can clearly see from the table that, (a₁ = 10), (a₂ = 15), (a₃ = 20), (a₄ = 25) and so on, and [(25 - 20) = (20 - 15) = (15 - 10) = 5], i.e.,
[(a₄ - a₃) = (a₃ - a₂) = (a₂ - a₁) = 5]. Hence, the common difference for (aₙ) is 5, and not 10.
Third statement is that, "(aₙ) can be modelled by a linear function, and (gₙ) can be modelled by an exponential function" which is true for the first part, but false for the second, making the complete statement false as whole.
From the left hand side table, we can see that, (a₂ = 15) and (a₁ = 10),
Or, [a₂ = (10 + 5)]
Or, [a₂ = (a₁ + 5)]
Similarly, (a₃ = 20),
Or, [a₃ = (15 + 5)]
Or, [a₃ = (a₂ + 5)]
That is, we can generalise (aₙ) as
[aₙ = {(aₙ₋₁) + 5}] where, (n = 2, 3, 4, 5...) and (a₁ = 10).
Hence, (aₙ) can be modelled by a linear function.
But from the right hand side table, we can see that, (g₂ = 4) and (g₁ = 2),
Or, [g₂ = (2 * 2)]
Or, [g₂ = 2g₁]
Similarly, (g₃ = 8),
Or, [g3 = (2 * 4)]
Or, [g₃ = 2g₂], it goes on for (gₙ).
Therefore, we can generalise (gₙ) as
[gₙ = 2*(gₙ₋₁)] where, (n = 2, 3, 4, 5...) and (g₁ = 2).
Here, (gₙ) can also modelled as a linear function and not as a exponential function (which goes in the form of "xⁿ").
Coming to the fourth statement, "Initially (aₙ) is greater than (gₙ), and as "n" gets larger, (gₙ) is greater than (aₙ)" is true, as from both the tables,
For (n = 5), [aₙ = a₅ = (a₄ + 5) = (25 + 5) = 30],
And [gₙ = g₅ = (2 * g₄) = (2 * 16) = 32], which is greater than 30,
Or, [(g₅) > (a₅)].
Similarly, for (n = 6), (a₆ = 35) while (g₆ = 64), i.e., [(g₆) > (a₆)], and it continues for greater values of "n".
Coming to the last statement, that [a₁₀ > g₆], is false. As we can observe from the both the tables and their sequence,
For (n = 5), (aₙ = 50), for (n = 6), (aₙ = 35), for (n = 7), (aₙ = 40), for (n = 8), (aₙ = 45), for (n = 9), (aₙ = 50) and for (n = 10), (aₙ = 55),
While on the other hand, for (n = 5), (gₙ = 32) and for (n = 6), (gₙ = 64).
Since (64 > 55), therefore, [(g₆) > (a₁₀)].

Given equal probabilities of the birth of a xy or xx, what is the probability that a group of four siblings includes all xy? all xx? all xy or all xx?.
The probability of all XY in a group of four siblings is 1/16 (6.5%), and also the probability of all XX offspring is 1/16 (6.5%).
Let us first know how do chromosomes work?
Long DNA molecules called chromosomes contain all or a portion of an organism's genetic code. Males receive one X and one Y chromosome from each parent, whereas females receive two X chromosomes from each parent.
For females, the likelihood or probability of inheriting two X chromosomes is 1/2 (50%) while for men, the probaility of receiving one X chromosome and one Y chromosome is similarly 1/2.
Therefore, the probability that all XY siblings are present in a group of 4 siblings is:
[tex]1/2 * 1/2 * 1/2 * 1/2 = 1/16[/tex]

The length of the park not counting the path is 98 yards
How to determine the length of the park
The formula for determining the area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the rectanglew is the width of the rectangleFrom the information given, we have that;
The dimensions of the path having a width of 1 yard path around it are
(L+2) x (W+2)
We have to add 2 to the length and width because there will be a 1 yard path on all 4 sides of the rectangle
Given that the area is 4200 square yards; the original width is 40 yards
Now, substitute the values into the formula, we have;
Since Area = LW
4200 = (L+2)(W+2)
4200 = (L+2)(40+2)
Add the values
4200 = (L+2)(42)
expand the bracket
4200 = 42L + 84

A cyclists speed is 1.5 times faster than a walkers speed. they simultaneously start moving in the same direction from the same point and, after 1.5 hours, the distance between them is 12.5 miles. what are their speeds?
Answer:
The biker's pace is 25 miles per hour and the walker's speed is 50/3 miles per hour.
Answer:The speed of the walker is 16.67 miles per hour.
The speed of the cyclist is 25 miles per hour.
How to calculate the value?
Let the speed of a walker = x
Biker's speed = 1.5x
Their relative speed will be:
= 1.5x - x = 0.5x
Distance between them = 12.5 miles
Time taken = 1.5 hours.
It should be noted that distance will be:
= Speed × Time
12.5 = 1.5 × 0.5x
Divide through to get x
12.5 = 0.75x
x = 16.67 miles per hour.
Speed of cyclist = 16.67 × 1.5 = 25 miles per hour.

open-top box is a function of the side length x in inches of the square cutouts.
Write an expression for V(x).
what is the volume of the box when x=6
The expression for volume is (28-2x)(22-2x)x and when x=6, the volume is 840 inch^3.
What is volume?
A 3D object's volume is the amount of actual space it occupies. It is a 2D shape's 3D equivalent of area. It is quantified in cubic units like cm3. It means that the amount of space a closed form can occupy in three dimensions depends on its volume. Volume is a gauge of a thing's potential. For instance, a cup is said to have a 100 ml capacity if the brim can hold 100 ml of water. Another way to measure volume is the amount of space a three-dimensional item takes up.
According to question,
Let x be the height of the cubic box
Length = (28-2x)
Breadth = (22-2x)
Volume = x(28-x)(22-x)
When x =6
Volume = 6(28-6×2)(22-6×2)

The exponents are solved below\
What are exponents?
Exponentiation is a mathematical process denoted by the symbol bn that involves two integers, the base b and the exponent or power n, and is spoken as "b (raised) to the (power of) n." Exponentiation corresponds to repeated multiplication of the base when n is a positive integer: bn is the product of multiplying n bases. Typically, the exponent is displayed as a superscript to the right of the base. In such scenario, bn is referred to as "b raised to the nth power," "b (raised) to the power of n," "the nth power of b," "b to the nth power," or, more succinctly, "b to nth." In other words, when a base raised to one exponent is multiplied by the same base raised to another exponent, the exponents accumulate.
The exponents are solved as follows
(10⁻²)⁹ = 10⁻¹⁸ = 1/10¹⁸
10⁻³ - 10⁻⁸ = 1/10³ - 1/10⁸ = (10⁵ - 10⁸)/10⁸ = 9.9999x10⁻⁴
