Answer:We can rewrite the expression |14-(6-x)| as follows:
When (6-x) is positive, 14-(6-x) = 14-6+x = x+8
When (6-x) is negative, 14-(6-x) = 14-6+x = x+8
Therefore, we can write the expression without the absolute value symbol as:
x+8
Step-by-step explanation: We have try the two cases when 6-x is negative and when it s positive

what is the ratio of water around in swamps to the total quantity of fresh water on the surface?
Answer:
Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.
Step-by-step explanation:
The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11
Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

When rolling a 6-sided die twice, determine P(sum of 4).
A. 3/36
B. 5/36
C. 6/36
D. 2/6
the probability of rolling a sum of 4 when rolling a 6-sided die twice is,
⇒ 3 / 36.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Now, To determine the probability of rolling a sum of 4 when rolling a 6-sided die twice, we need to first find all the possible outcomes when rolling a die twice.
Since, There are 6 possible outcomes when rolling a single die:
1, 2, 3, 4, 5, or 6.
Now, When rolling two dice, we can combine each of these outcomes with every other outcome.
Hence, This gives us a total of 6 x 6 = 36 possible outcomes when rolling two dice.
Thus, To find the number of outcomes that add up to 4, we can list them out:
1 + 3
2 + 2
3 + 1
So, there are three possible outcomes that add up to 4.
Hence, To find the probability of rolling a sum of 4, we need to divide the number of outcomes that add up to 4 by the total number of possible outcomes:
⇒ P(sum of 4) = 3/36
Therefore, the probability of rolling a sum of 4 when rolling a 6-sided die twice is 3 / 36.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
A click beetle abruptly releases elastic energy stored in its body to launch itself into the air. The function h(t)=−16t^2+8t represents the height h (in feet) of the click beetle t seconds after launching. The height of a second click beetle t seconds after launching is shown in the graph. Which click beetle went higher?
Answer:
The first click beetle went higher.
Step-by-step explanation:
The vertex is the minimum point of a parabola that opens upwards, or the maximum point of a parabola that opens downwards.
Since the height of each of the beetles at time, t seconds, is modelled as a parabola that opens downwards, the maximum height of each beetle is the y-value of the vertex.
First Click BeetleThe function representing the height, h, of the first beetle is:
\(h(t)=-16t^2+8t\)
We could complete the square to rewrite the function in vertex form, however the quickest way to find the vertex of a quadratic function in the form ax² + bx + c is to use the formula for the x-value of the vertex:
\(\boxed{x_{\sf vertex}=-\dfrac{b}{2a}}\)
Comparing ax² + bx + c with the given function:
a = -16b = 8c = 0Therefore, substituting the values of a and b into the formula, the x-value of the vertex of h(t) is:
\(x_{\sf vertex}=-\dfrac{8}{2(-16)}=0.25\)
To find the y-value of the vertex, and thus the maximum height of the first beetle, simply substitute t = 0.25 into function h(t):
\(\begin{aligned}\implies h(0.25)&=-16(0.25)^2+8(0.25)\\&=-16(0.0625)+2\\&=-1+2\\&=1\end{aligned}\)
Therefore, the maximum height of the first beetle is 1 foot.
Second Click BeetleFrom inspection of the given graph modelling the height of the second beetle, we can see that the maximum y-value is approximately 0.76 feet.
ConclusionAs the height of the second click beetle is less than the maximum height of the first click beetle, the first beetle went higher.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16

Step-by-step explanation:
Vertical angle means same angle .
x + 29 = 6x - 11

x = 8
Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅
The table shows the battery life of four different mobile phones:
Mobile Phone Battery Life Phone
Battery Life (hours)
A 20
B 25
C 10
D 18
If 8.45% of the battery life of each mobile phone is used in a day by a typical user, which mobile phone would use a total of 1.69 hours of battery life in a day?
Phone A
Phone B
Phone C
Phone D
Answer:
Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845
If you want to compute out the four results with a calculator, then it would look like this:
0.0845*20 = 1.69
0.0845*25 = 2.1125
0.0845*10 = 0.845
0.0845*18 = 1.521
and this shows that no other result (but choice C) is close to 0.8
So that's why the answer is choice C

The length of a rectangle is 3 ft longer than its width. The perimeter of the rectangle is 30 ft. Write an equation to represent the perimeter in terms of its width w. What is the length of the rectangle?
Answer:
Let the width of the rectangle be w.
Let the length of the rectangle be l.
★ If the length is 3 feet longer than the width, then the length can be written in terms of the width as:
l = w + 3Now, the formula for finding the perimeter is p = 2l + 2w.
Substituting the values in this formula -\( \\ \implies \sf \: p = 2(w + 3) + 2w \\ \\ \\ \implies \sf \: p = 2w + 6 + 2w \\ \\ \\ \implies \sf \: p = 4w + 6 \\ \)
Substituting P = 30 for p ( allows us to solve for p) -\( \\ \implies \sf \: 30 = 4w + 6 \\ \\ \\ \implies \sf \: 30 - 6 = 4w + 6 - 6 \\ \\ \\ \implies \sf24 = 4w \\ \\ \\ \implies \sf \: w = \frac{24}{4} \\ \\ \\ \dag \: \large{ \underline{ \boxed{ \sf{ \: w = 6 \: cm}}}} \\ \)
Substituting w = 6 for l in the equation l = w + 7 -

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.
