Answer:
|x - 9| = 4
Step-by-step explanation:
All numbers x that are at a distance of 4 fro the number 9
Given two numbers a and B, the absolute distance between them is written as :
|a - b| = c
Hence all numbers x at distance of x from 9
|x - 9| = 4
{x : |x - 9| = 4}

The soccer club has planned a trip to a tournament. The cost of the van is
$231. When 3 students who are not members of the club join the trip, the
transportation cost per person drops by $4.50. How many soccer club
members are going to the tournament?
A. 14
B. 11
C. -14
D. -14, 11
Answer: B: 11
Step-by-step explanation:
Just to the quiz for it
An equation is formed of two equal expressions. The number of players going to the tournament is 11.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Since the cost of the van is fixed, therefore, 231. Thus, the two equations can be written as,
P × x = 231(P-4.50)×(x+3)=231Solving the above two equations we will get,
Px + 3P - 4.50x -13.5 = 231
3P - 4.50x - 13.5 = 0
3P - 4.50x = 13.5
3(231/x) - (4.50x) = 13.5
693 - 4.50x² = 13.5x
-4.50x² - 13.5x + 693 = 0
x² + 3x - 154 = 0
x = -14, 11
Since the number of members can not be negative, the number of players going to the tournament is 11.

Ocean waves crash on the beach at a
velocity of 4.4 m/s. If the distance
between the crest of each wave is 4m,
find the frequency of the waves.
Answer:
f = 1.1 Hz
Step-by-step explanation:
Given that,
The velocity of an ocean wave, v = 4.4 m/s
The distance between the crest of each wave is 4 m.
We need to find the frequency of the waves.
The distance between the crest of a wave is called the wavelength of a wave.
The relation between the frequency, wavelength and the velocity of a wave is given by :
[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{4.4}{4}\\\\f=1.1\ Hz[/tex]
So, the frequency of the waves is 1.1 Hz.

Answer:
1st part is 958
2nd part is 1024
Step-by-step explanation:
Answer:
a. 958 inches
b. 1024 inches
Step-by-step explanation:
a. The perimeter is 2(234+245) = 958 inches, by the formula of the perimeter of a rectangle.
b. This will increase the perimeter by 2 * 33 = 66 inches (because we're increasing in one dimension), so the answer is 958 + 66 = 1024 inches.

Step-by-step explanation:
2/3 of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 15 red boats, how many boats are in the marina?
Answer: The total boats in the marina are 105.
Step-by-step explanation:
Let the total number of boats in the marina = x
Given : Number of white boats in the marina = [tex]\frac{2}{3}x[/tex]
Number of blue boats in the marina = [tex]\frac{4}{7}\times (x-\frac{2x}{3})=\frac{4}{7}\times \frac{x}{3}=\frac{4x}{21}[/tex]
Number of red boats in the marina = [tex]x-\frac{2x}{3}-\frac{4x}{21}=\frac{3x}{21}[/tex]
Given : Number of red boats in the marina = 15
[tex]\frac{3}{21}\times x=15[/tex]
[tex]x=105[/tex]
Thus total boats in the marina are 105.
By working with fractions and proportions, we will see that there are 105 boats in the marina.
Working with the given information:
Let's say that there are N boats in the marina, we know that:
2/3 of these are white, then the proportion of boats that are not white is:
1 - 2/3 = 3/3 - 2/3 = 1/3.
Of these, 4/7 are blue, then the proportion of red ones is:
1 - 4/7 = 7/7 - 4/7 = 3/7
The total proportion of red boats is:
(3/7)*(1/3) = 1/7
And we know that there are 15 red boats, this means that:
(1/7)*N = 15
Solving for N we get:
N = 7*15 = 105
So there are 105 boats in the marina.

[tex]y =2(4)^{x} \\y = 2(4)^{0} = 2(1) = 2\\y = 2(4)^{1} = 2(4) = 8\\y = 2(4)^{2} = 2(16) = 32\\y = 2(4)^{3} = 2(64) = 128[/tex]

Step-by-step explanation:
[tex][Kindly\ refer\ the\ attachment.]\\We\ are\ given\ that,\\\triangle ABC\ is\ a\ right-triangle\ and\ has\ it's\ legs\ x\ and\ z.\\It's\ altitude\ CD\ separates\ it\ into\ two\ triangles:\\\triangle BCD\ and\ \triangle ADC,\ both\ of\ which\ are\ right-triangles.\\Now,\\The\ Pythagoras\ Theorem\ tells\ us\ that:\\'The\ sum\ of\ squares\ of\ both\ the\ legs\ is\ equal\ to\ the\ square\ of\ the\\ hypotenuse'.\\Here,\\Lets\ consider\ three\ triangles\ separately.\\[/tex]
[tex]In\ \triangle ADC\ right\ angle\ is\ at\ \angle ADC.\\Hence,\\AC\ is\ the\ hypotenuse, and\ AD\ and\ DC\ are\ it's\ legs.\\Hence,\\AD^2+DC^2=AC^2\\Or,\\9^2+y^2=x^2\\\\Lets\ take\ the\ above\ equation\ as\ E_1.[/tex]
[tex]In\ \triangle BDC\ right\ angle\ is\ at\ \angle BDC.\\Hence,\\BC\ is\ the\ hypotenuse, and\ DC\ and\ DB\ are\ it's\ legs.\\Hence,\\DC^2+DB^2=BC^2\\Or,\\21^2+y^2=z^2\\Lets\ take\ the\ above\ equation\ as\ E_2.[/tex]
[tex]Now,\\In\ whole\ \triangle ACB\ right\ angle\ is\ at\ \angle ACB.\\Hence,\\AB\ is\ the\ hypotenuse, and\ AC\ and\ BC\ are\ it's\ legs.\\Hence,\\AC^2+BC^2=AB^2\\Or,\\x^2+z^2=(21+9)^2=30^2\\Lets\ take\ the\ above\ equation\ as\ E_3.[/tex]
[tex]Lets\ now\ gather\ the\ three\ equations:\\9^2+y^2=x^2\\21^2+y^2=z^2\\x^2+z^2=30^2\\Now,\\Lets\ pair\ and\ add\ E_1\ and\ E_2.\\Hence,\\(9^2+y^2)+(21^2+y^2)=(x^2)+(z^2)\\Hence,\\81+y^2+441+y^2=x^2+z^2\\Hence,\\2y^2+522=x^2+z^2\\Considering\ E_3,\\We\ already\ know\ that,\\x^2+z^2=30^2\\Hence,\\2y^2+522=30^2\\Hence,\\2y^2+522=900\\2y^2=900-522=378\\Hence,\\y^2=\frac{378}{2}=189\\Hence,\\y=\sqrt{189}=13.7\\[/tex]
[tex]Plugging\ in\ y=13.7\ in\ E_1,\\9^2+(13.7)^2=x^2\\81+189=x^2\\x^2=270\\x=\sqrt{270}=16.4[/tex]

Answer:
[tex]\frac{1}{1892}[/tex]
Step-by-step explanation:
There are two possibilities for each of 13 questions, true or false. As a result, you have a [tex]\frac{1}{2}[/tex] chance of choosing either of the choices. To find this, you would multiply the probability to the power of the number of cases, meaning [tex](\frac{1}{2^(13)})=\frac{1}{1892}[/tex].
