5. The dimensions, in inches, of a shipping box at We Ship 4 You can be expressed as width x, length x + 5, and height 3x - 1. The volume is about 7.6 f3. Find the dimensions of the box in inches. Round to the nearest inch. (Hint: 1 f 1,728 in.3)
To find the dimensions of the shipping box, calculate the volume in cubic inches, then set up and solve the volume equation x(x + 5)(3x - 1), substituting the given volume after conversion from cubic feet. Solve for x, then use it to find and round the box's dimensions.
Explanation:To find the dimensions of the shipping box, we need to calculate the volume using the given dimensions in inches and compare it to the provided volume in cubic feet. Recall that the conversion factor between cubic feet and cubic inches is 1 cubic foot equals 1,728 cubic inches. Firstly, convert the volume of the box from cubic feet to cubic inches: 7.6 cubic feet are 7.6 x 1,728 cubic inches.
Next, we can set up the volume equation for the box using the given dimensional expressions: volume = width x length x height, which for this box is x x (x + 5) x (3x - 1). Now we solve the equation for x given that the volume in cubic inches is equal to 7.6 x 1,728 inches.
Once x is found, we can determine the width, length, and height by plugging x back into the expressions x, x + 5, and 3x - 1, respectively, and rounding each to the nearest inch.
Out of 100 lottery tickets, each having 50% chance of winning, 2 tickets are bought at random. what is the probability that at least one ticket will win?
If a penny is tossed three times and comes up heads all three times, the probability of heads on the fourth trial is ___.
The coming head in the fourth time is independent of the coming head in the first three times thus the probability of coming head in the fourth time is 1/2.
What is probability?Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
As per the given,
In the first three attempts coming head in the first three times.
In the fourth attempt, the probability will be independent of the first three events.
Thus, the probability of coming ahead in the fourth time will be as,
Number of desire output/number of total output
=> 1 / 2
Hence "The coming head in the fourth time is independent of the coming head in the first three times thus the probability of coming head in the fourth time is 1/2".

The perimeter of a rectangular concrete patio is 34 meters. the area is 70 square meters. what are the dimensions of the patio?
To find the dimensions of the rectangular patio, use the equations for perimeter and area and solve for length and width.
Explanation:To find the dimensions of the rectangular patio, we can use the given information about its perimeter and area. Let's assume the length of the patio is L and the width is W.
The perimeter is given as 34 meters, which is equal to 2L + 2W. So, we have the equation 2L + 2W = 34.
The area is given as 70 square meters, which is equal to L * W. So, we have the equation L * W = 70.
We can use these equations to solve for L and W using substitution or elimination method.

calculate the rate of change for the quadratic function over the given interval:
f(x)=x^2 + 4x +5 ; -4 =< x =< -2
The rate of change of the quadratic function over the interval −4≤x≤−2 is 2.
To find the rate of change of the quadratic function [tex]$f(x)=x^2+4 x+5$[/tex] , over the interval −4≤x≤−2, we need to find the average rate of change over that interval.
The average rate of change of a function f(x) over an interval [a,b] is given by:
[tex]Average Rate of Change =\frac{f(b)-f(a)}{b-a}$[/tex]
So, in this case:
a=−4
b=−2
We calculate f(−4) and f(−2):
[tex]$\begin{aligned} & f(-4)=(-4)^2+4(-4)+5=16-16+5=5 \\ & f(-2)=(-2)^2+4(-2)+5=4-8+5=1\end{aligned}$[/tex]
Now we can find the rate of change:
Rate of Change = [tex]$\frac{1-5}{-2-(-4)}=\frac{-4}{-2}=2$[/tex]
The average rate of change of the function f(x)=x² + 4x + 5 over the interval from x = -4 to x = -2 is -2.
The rate of change for the quadratic function f(x)=x² + 4x + 5 over the interval from x = -4 to x = -2 can be calculated using the average rate of change formula. This formula is given by:
Rate of Change = [f(x2) - f(x1)] / (x2 - x1)
Where x1 = -4 and x2 = -2. We first calculate f(-4) and f(-2) by plugging these values into the function:
f(-4) = (-4)² + 4(-4) + 5 = 16 - 16 + 5 = 5
f(-2) = (-2)² + 4(-2) + 5 = 4 - 8 + 5 = 1
Now we use these results in our rate of change formula:
Rate of Change = (1 - 5) / (-2 + 4) = -4 / 2 = -2
The average rate of change of the function f(x) over the interval from x = -4 to x = -2 is -2.

[tex]\begin{aligned}-(x+4)&=2\\-x-4&=2\\-x&=2+4\\-x&=6\\x&=-6\end{aligned}[/tex]
Therefore, for [tex]x<-4[/tex] the value of [tex]x[/tex] which satisfies the equation [tex]|x+4|=2[/tex] is [tex]x=-6[/tex].
This implies that the solution for the equation [tex]|x+4|=2[/tex] or the value of [tex]x[/tex] which satisfies the given equation are [tex]\fbox{\begin\\\ \math x=-2\ \text{and}\ x=-6\\\end{minispace}}[/tex].

What is the value of x in the figure below? In this diagram, ΔABD ~ ΔCAD.
The value of x in the figure given is E. √70.
The answer is E. √70.
The two triangles are similar by the AAA Similarity Theorem, since they have two pairs of congruent angles, namely ∠ABD and ∠CAD, and ∠BAD and ∠CDA.
Since the triangles are similar, the ratio of corresponding sides is constant. In particular, the ratio of AD to CD is the same as the ratio of BD to AD.
We are given that AD = 14 and CD = 20, so the ratio of AD to CD is 14/20. We are also given that BD = x, so the ratio of BD to AD is x/14.
Setting these two ratios equal to each other, we get x/14 = 14/20, which simplifies to x = √70.
Here is a proof that shows why the two triangles are similar:
AAA Similarity: Triangles ABD and CAD have two pairs of congruent angles, namely <ADB> and <CAD>, because they are both right angles.
SSS Similarity: Triangles ABD and CAD have three pairs of corresponding sides that are proportional, namely AD/CD = 14/20, BD/AD = x/14, and AB/CD = √70/20. Therefore, the two triangles are similar by the SSS Similarity Theorem.
