If 3K is x% of 3000, then an expression for x is..?
well, let's see it this way, we know that 3000 is the 100%, and we also know that 3K is x% of 3000, so then
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 3000 & 100\\ 3K& x \end{array} \implies \cfrac{3000}{3K}=\cfrac{100}{x} \\\\\\ 3000x=300K\implies x=\cfrac{300K}{3000}\implies x=\cfrac{K}{10}[/tex]

Given \tan \theta =0.6, find the value of b.
Answer:
b=8.5cm
Step-by-step explanation:
tanx (this represents tan theta, it's just easier to type) is equal to 0.6 and since the tanx ratio is opp/adj, we know that opp/adj = 0.6
To find what b is (adjacent as it is adjacent to the angle being used and it is not the hypotenuse), we just have to rearrange.
0.6=5.1/adj
to solve for adj, we can switch 0.6 and adj. (This works because to get adj by itself on one side you would multiply it to the other side and then divide 0.6 from both sides --> simple algebra)
so then you have
adj=5.1/0.6
adj=8.5cm
(if you want to check your solution you can use pythagoeran theorem, a^2+b^2=c^2) and sub everything in and make sure all the numbers equal the right thing!

In how many ways can 6 students be seated in a row of 6 seats if 2 of the students insist on sitting beside each other?
Using the arrangements formula, it is found that there are 240 ways for the students to sit.
What is the arrangements formula?The number of possible arrangements of n elements is given by the factorial of n, that is:
[tex]A_n = n![/tex].
In this problem:
The 2 students can sit in 2! ways, in 5 positions(1 and 2, 2 and 3, 3 and 4, 4 and 5 or 5 and 6).The remaining 4 students can sit in 4! ways.Hence:
T = 5 x 2! x 4! = 240.
There are 240 ways for the students to sit.

Which system of equations can be used to find the roots of the equation 4 x squared = x cubed 2 x? startlayout enlarged left-brace 1st row y = negative 4 x squared 2nd row y = x cubed 2 x endlayout startlayout enlarged left-brace 1st row y = x cubed 4 x squared 2 x 2nd row y = 0 endlayout startlayout enlarged left-brace 1st row y = 4 x squared 2nd row y = negative x cubed minus 2 x endlayout startlayout enlarged left-brace 1st row 4 x squared 2nd row y = x cubed 2 x endlayout
The system of equations can be used to find the roots of the considered equation is y = 4+x^2 and y= x^3 + 2 + x
How can we find the solution to an equation?We do same operations on both the sides so that equality of both expressions doesn't get disturbed. Solving equations generally means finding the values of the variables used in it for which the considered equation is true.
Sometimes we can find such value, and sometimes it is not possible at all, or sometimes, there are infinite number of solutions.
For the given case, we are given with the equation [tex]4+x^2 = x^3 + 2 + x[/tex]
We can take two equations as:
[tex]y = 4+x^2 \\y= x^3 + 2 + x[/tex]
And when we will try to solve this system of equation, we will end up substituting the value of y in terms of x, and therefore, ending up on the same equation [tex]4+x^2 = x^3 + 2 + x[/tex]

The base of a solid is bounded by x^2 + y^2 = 16. Cross sections perpendicular to the x-axis are right isosceles triangles with one leg located in the base. Which definite integral represents the volume of this solid?
The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.
x² + y² = 16 ⇒ y = ±√(16 - x²)
⇒ length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)
Cross sections with thickness ∆x have a volume of
1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x
since they are isosceles triangles and so their bases and heights are equal.
Then the total volume would be (D)
[tex]\displaystyle \int_{-4}^4 \frac12 \left(2 \sqrt{16-x^2}\right)^2 \, dx[/tex]
The amount of $300 was deposited into a continuously compounded interest account that paid 0.5% interest per year. Which of the following expressions would be used to
determine the number of years it would take for the account to have a balance of $600?
The expression that can be used to determine the number of years that it would take to have a balance of $600 is In2 ÷ In[tex]e^{0.005}[/tex].
How long would it take to have a balance of $600?When an amount is compounded continously, it means that both the amount deposited and the interest already accrued increases in value continously over a period of time.
Time = In(FV/PV) ÷ In([tex]e^{0.005}[/tex]
In2 ÷ In[tex]e^{0.005}[/tex]

The scientist had a 35% saline solution that he mixed with 10 milliliters of a 75% saline solution to get a 40% saline solution. How many milliliters of the 35% solution were used?
x mL of the 35% saline solution contains 0.35x mL of salt.
10 mL of the 75% solution contains 0.75 • 10 mL = 7.5 mL of salt.
After mixing, the scientist would have a total volume of (x + 10) mL. We know its concentration is 40%, so it contains 0.40 (x + 10) mL of salt.
The total amount of salt before and after mixing must be the same, so
0.35x + 7.5 = 0.40 (x + 10)
Solve for x :
0.35x + 7.5 = 0.40x + 4.0
0.10x = 3.5
x = 35
The scientist used 35 mL of the 35% solution.

directly as the temperature T and inversely as the
pressure P. If V = 341.0 in 3 when T = 310° and

and P= 15 lb/in.2?
Apply combine gas law
[tex]\\ \rm\dashrightarrow \dfrac{P1V1}{T1}=\dfrac{P2V2}{T2}[/tex]
[tex]\\ \rm\dashrightarrow \dfrac{10(341)}{310}=\dfrac{15V2}{120}[/tex]
[tex]\\ \rm\dashrightarrow 11=\dfrac{V2}{8}[/tex]
[tex]\\ \rm\dashrightarrow V2=88in^3[/tex]
Answer:
88 in³
Step-by-step explanation:
we are given that the volume V of a given mass of gas varies directly as the temperature T and inversely as the pressure P.
Condition-1:
The volume V of a given mass of gas varies directly as the temperature T , thus
[tex]V\propto T\\\implies V=kT[/tex]
Condition-1:
The volume V of a given mass of gas varies inversely as the pressure P, therefore,
[tex]V\propto 1/P\\\implies V=k\cdot 1/P[/tex]
combining 1 and 2 yields
[tex]V\propto k\cdot T/P[/tex]
Case-1:
V = 341.0 in³T = 310°P=10 lb/in²To find:
kFinding the constant of proportionality
[tex]341= k\cdot 310/10\\\implies k=341\times 10/310 \\ \implies \boxed{k=11}[/tex]
Case-1:
To find:
Vwhen:
T = 120°P=15 lb/in²k=11Finding the volume:
[tex]V= 11\times 120/15\\\implies V=11\times 8 \\ \implies \boxed{V=88}[/tex]
