Sally can paint a room in 5 hours while it takes Steve 7 hours to paint the same room. How long will it take them to paint the room if they work together?
(Type an integer or decimal rounded to one decimal place as needed)
=====================================================
Explanation:
Let's say the room has walls and ceiling of 350 sq ft in total area.
Sally can paint this area in 5 hours when working alone, so her unit rate is 350/5 = 70 sq ft per hour.
Steve needs 7 hours to do the same job when working alone, so his unit rate is 350/7 = 50 sq ft per hour.
Assuming the two people can work together without hindering each other (i.e. without getting in each other's way), then the two unit rates combine to 70+50 = 120 sq ft per hour.
Divide the total area over this combined unit rate
350/120 = 2.91667 approximately
This rounds to 2.9
--------------
Alternatively, you can solve the equation
[tex]\frac{1}{5} + \frac{1}{7} = \frac{1}{x}[/tex]
And you should get roughly x = 2.9

in 1960 the population of Indonesia was 88 million. in 2010 the population of Indonesia was 242 million. *calculate the percentage increase from 1960 to 2010? *estimate the population in 2060 if the rate of increase doesn't change
Answer:
Step-by-step explanation:
1960 = 88,000,000
2010 = 242,000,000
formula: (new-old)/old* 100
(242,000,000 - 88,000,000)/88,000,000 * 100
154,000,000/88,000,000*100

27 is what percent of 81?
Answer:
33.3333333%
Step-by-step explanation:
Let's set up the equation:
x 27
--- = ---
100 81
100 x 27 = 2700
2700 ÷ 81 = 33.3333333
So x equals 33.3333333 of a hundred, or in other words, 33.3333333%
Therefore 27 is 33.3333333% of 81.

The area of a parallelogram is 91.2cm2, base is l2cm. Find its height.
Answer:
7.6 cm
Step-by-step explanation:
The formula to find the area of the parallelogram is :
Area = Base × Height
They have already given,
Area = 91.2 cm²
Base = 12 cm
Height =?
To find the height, let the height be h.
Let us solve it now.
Area = Base × Height
91.2 cm² = 12 cm × h
Divide both sides by 12.
7.6 cm = h
Therefore, the height is 7.6 cm.

Given Integral is:
[tex] \\ { \displaystyle{ \int{ \large{ \rm{ \frac{1}{x( {x}^{3} + 1) }dx }}}}} \\ [/tex]
Can be written as:
[tex] \\ { \large{ \longrightarrow{ \displaystyle{ \int { \rm{\frac{3 {x}^{2} }{3 {x}^{2} \times x( {x}^{3} + 1) } dx}}}}}}[/tex]
[tex] \\ { \large{ \longrightarrow \frac{1}{3} \: { \displaystyle{ \int{ \rm { \frac{ {3x}^{2} }{ {x}^{3} ( {x}^{3} + 1)} dx}}}}}}[/tex]
Now to evaluate this integral , we use the method of Substitution.
So, Substitute:
[tex] \: \: \: \: \: \: \: \: \: \: \: \: { \rightarrow \: {\large{\rm{ {x}^{3} = y}}}}[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \rightarrow \: { \large{ \rm{3 {x}^{2} dx = dy}}}[/tex]
So, on Substituting the values in above integral, we get:
[tex] \\ { \large{ \longrightarrow{ \frac{1}{3} \: \displaystyle{ \int{\rm{ \frac{1}{y(y + 1)} }}}}}}[/tex]
[tex] \\ { \large{ \longrightarrow{ \frac{1}{3} \: { \displaystyle{ \int{ \rm{ \frac{1 + y - y}{y(y + 1)}dy }}}}}}}[/tex]
[tex] \\ { \large{ \longrightarrow{ \frac{1}{3} \: { \displaystyle{ \int{ {\rm{ \frac{y + 1 - y}{y(y + 1)}dy }}}}}}}}[/tex]
[tex] \\ { \large{ \longrightarrow{ \frac{1}{3} \: { \displaystyle{ \int{ \rm{ \left[ \frac{1}{y} - \frac{1}{y + 1} \right ] }dy}}}}}}[/tex]
[tex]{ \large{ \longrightarrow{ \rm{ \frac{1}{3} \left( log |y| - log |y + 1| \right) + c}}}}[/tex]
[tex]{ \large{ \longrightarrow{ \rm{ \frac{1}{3} log | \frac{y}{y + 1} | + c }}}}[/tex]
[tex]{ \large{ \longrightarrow{ \rm{ \frac{1}{3} log | \frac{ {x}^{3} }{ {x}^{3} + 1 } | + c }}}}[/tex]
Hence,
[tex] \\{ \boxed{ \pink { \large{ \displaystyle{ \int{ \rm{ \frac{dx}{x ({x}^{3 } + 1 )} = \frac{1}{3 } log{ \huge{ |}} \frac{ {x}^{3} }{ {x}^{3} + 1} { \huge{ | }} + c}}}}}}}[/tex]
After applying algebraic substitution, partial fraction decomposition and integration rules the integral of the non-trascendental expression [tex]\frac{1}{x\cdot (x^{3}+1)}[/tex] is equal to the trascendental expression [tex]I = \frac{1}{3}\cdot \ln \left|\frac{x^{3}}{x^{3}+1} \right| + C[/tex].
How to determine the indefinite integral of a given expressionAccording to the statement we have an integrable rational expression formed by non-trascendental expressions, that is, expressions whose behavior is described solely by algebraic components. This expression can be solved by algebraic substitution after making the following modifications:
[tex]\int {\frac{dx}{x\cdot (x^{3}+1)} } = \int {\frac{3\cdot x^{2}}{3\cdot x^{3}\cdot (x^{3}+1)} } \, dx = \frac{1}{3}\int {\frac{3\cdot x^{2}}{x^{3}\cdot (x^{3}+1)} } \, dx[/tex]
And the following substitutions are used: u = x³, du = 3 · x² dx
[tex]\frac{1}{3} \int {\frac{du}{u \cdot (u+1)} }[/tex]
This is expression is equivalent to the following by partial fraction decomposition:
[tex]-\frac{1}{3}\int {\frac{du}{u+1} } \, du +\frac{1}{3}\int {\frac{du}{u} }[/tex]
And the integral is now solved:
[tex]I = -\frac{1}{3}\cdot \ln |u+1| + \frac{1}{3}\cdot \ln |u| + C[/tex]
[tex]I = \frac{1}{3}\cdot \ln \left|\frac{u}{u+1} \right| + C[/tex]
[tex]I = \frac{1}{3}\cdot \ln \left|\frac{x^{3}}{x^{3}+1} \right| + C[/tex]
Where C is the integration constant.
After applying algebraic substitution, partial fraction decomposition and integration rules the integral of the non-trascendental expression [tex]\frac{1}{x\cdot (x^{3}+1)}[/tex] is equal to the trascendental expression [tex]I = \frac{1}{3}\cdot \ln \left|\frac{x^{3}}{x^{3}+1} \right| + C[/tex].

Please help. Find the solution to the system of linear equations. Show work.
Answer:
(1, -3)
Step-by-step explanation:
To find the solution of the system of linear equations, first you need to set them equal to each other and solve.
y = x-4
y = -2x-1
x-4 = -2x-1
x + 2x = -1 + 4
3x = 3
x = 1
To find the corresponding y-value, plug the calculated x into one of the equations (it doesn't matter which one you choose because they will give the same result).
y = x-4
y = 1 - 4
y = -3

Which of the following values for x and y make the equation 4x + 2y + 3 = 19 true?
x=5, y = 3
x = 4, y = 5
x = 3, y = 2
x = 2, y = 5
Solution:
Option A
4x + 2y + 3 = 19=> 4(5) + 2(3) + 3 = 19=> 20 + 6 + 3 = 19=> 29 = 19 (False)Option B
4x + 2y + 3 = 19=> 4(4) + 2(5) + 3 = 19=> 16 + 10 + 3 = 19=> 29 = 19 (False)Option C
4x + 2y + 3 = 19=> 4(3) + 2(2) + 3 = 19=> 12 + 4 + 3 = 19=> 19 = 19 (True)Option D
4x + 2y + 3 = 19=> 4(2) + 2(5) + 3 = 19=> 8 + 10 + 3 = 19=> 21 = 19 (False)Option C is correct.
Answer:
5
Step-by-step explanation:
Part A: 4 x 6 = 24 - 5 = 19 = 19, and v= is equal to or less than. Because 19 is the same as 19, saying it is larger than is false.
Part B (of two):
The answer is incorrect: 4 x 4 = 16 + 3 = 19 = 23.
20 + 3 = 23 = 23 = 4 x 5 = 20 x 5 = 20 x 5 = 20 x 5 = 20 x True, but we should also consider the other possibilities.
Incorrect: 4 x 6 = 24 + 3 = 27 = 23
Incorrect: 4 x 7 = 28 + 3 = 31 = 23
Incorrect: 4 x 8 = 32 + 3 = 35 = 23
As a result, 5 is the correct response!

Step-by-step explanation:
Let's use Q10 as an example and you will work on Q11-12 as they are the same.
I believe the middle column (5x-4) wants you to substitute the given x, so:
Q10.1: 5(-2)-4
Q10.2: 5(4)-4
Q10.3: 5(0)-4
Q10.4: 5(1)-4
The right most column (f(x)) should be asking you the answers from your middle column, so:
Q10.1: -14
Q10.2: 16
Q10.3: -4
Q10.4: 1
As for the domain and range, let's define these two names in case you haven't learnt them:
Domain: What reasonable x values can be inputted into the function.
Range: What reasonable results will be shown after calculating.
In these case, you can input any real numbers into x as you like into the function, the results will always be other real numbers.
Hence, for Q10-12, D and R should be "All real numbers"
Just some extra info, Let the function f(x) be [tex]\frac{1}{x+1}[/tex]. Since the denominator cannot be 0 in a fraction, we say that the domain of x is "All real numbers except -1" as [tex]-1+1 = 0[/tex] and [tex]\frac{1}{0}[/tex] is undefined.
