Step-by-step explanation:

To find the LCD of the different fractions, we first need to follow the steps of finding the LCD of algebraic fractions.

1st step: Factor

You need to factor out the expressions if they do not have a difference of two squares.

2nd step: Find the LCD of the coefficients.

You need to find the LCD of the coefficients before moving onto the variables.

3rd step: The variable part of the LCD will be every single variable you see, with the highest exponent.

So let's begin, since all the given denominators are already factored out, we can proceed straight to step 2.

[tex]\dfrac{5}{9m^{2}n}and\dfrac{5}{16mn^{3}}[/tex]

Now since we're dealing with the denominators, let's focus on them alone.

The LCD of 9 and 16 is 144

The LCD of variables m² and m is m²

The LCD of variables n and n³ is n²

So the LCD of the algebraic fractions [tex]\dfrac{5}{9m^{2}n}and\dfrac{5}{16mn^{3}}[/tex] is:

144m²n³

Now to the next one.

[tex]\dfrac{5+m}{8m^{4} n^{2} }and\dfrac{5+n}{18m^{2} n^{4} }[/tex]

The LCD of 8 and 18 is 72

The LCD of variables [tex]m^{4}[/tex] and m² is [tex]m^{4}[/tex]

The LCD of variable n² and [tex]n^{4}[/tex] is [tex]n^{4}[/tex]

So the LCD of the algebraic fractions [tex]\dfrac{5+m}{8m^{4} n^{2} }and\dfrac{5+n}{18m^{2} n^{4} }[/tex]is:

[tex]72m^{4} n^{4}[/tex]

Next one we have:

[tex]\dfrac{m+n}{12mn}and\dfrac{n+m}{18m^{3}n }[/tex]

The LCD of 12 and 18 is 36

The LCD of m and m³ is m³

The LCD of n and n is n

So the LCD of the algebraic fractions [tex]\dfrac{m+n}{12mn}and\dfrac{n+m}{18m^{3}n }[/tex] is:

36m³n

Last but not the least.

[tex]\dfrac{m-n}{24mn^{4}}and\dfrac{m-n}{16m^{4}n }[/tex]

The LCD of 24 and 16 is 48

The LCD of m and [tex]m^{4}[/tex] is [tex]m^{4}[/tex]

The LCD of [tex]n^{4}[/tex] and n is [tex]n^{4}[/tex]

So the LCD of the algebraic fractions [tex]\dfrac{m-n}{24mn^{4}}and\dfrac{m-n}{16m^{4}n }[/tex] is:

[tex]48m^{4} n^{4}[/tex]

Answer:

The perimeter of rectangle is [tex]18\ cm[/tex]

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

[tex]x=y+5[/tex] ----> equation A

[tex]120=xy+2x^{2}+2y^{2}[/tex] ---> equation B (area of the constructed figure)

substitute the equation A in equation B

[tex]120=(y+5)y+2(y+5)^{2}+2y^{2}\\ 120=(y+5)y+2(y+5)^{2}+2y^{2}\\ 120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\ 120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\120=5y^{2}+25y+50\\5y^{2}+25y-70=0[/tex]

using a graphing calculator -----> solve the quadratic equation

The solution is

[tex]y=2\ cm[/tex]

Find the value of x

[tex]x=y+5 ----> x=2+5=7\ cm[/tex]

Find the perimeter of rectangle

[tex]P=2(x+y)=2(7+2)=18\ cm[/tex]

Answer:

Perimeter of rectangle = 38 cm

Step-by-step explanation:

It is given that, Length of a rectangle is 5 cm longer than the width.

Let 'x' be the width then length = x + 5

Area of of rectangle = x(x + 5)

One side of square = ( x+ 5)/4

Area of all squares = [(x +5)/4]² * 4 = (x + 5)²/4

To find the value of x

Total area = 120 cm²

Area of of rectangle + Area of all squares  = 120

x(x + 5) + (x + 5)²/4 = 120

x² + 5x + (x² + 10x + 25)/4 = 120

4x² + 20x + x² + 10x + 25 = 120 * 4

x² + 6x + 5  = 24 * 4

x² + 6x - 96 =0

x = 7

To find the perimeter of rectangle

width = x = 7

Length = x + 5 = 7 + 5 = 12

Perimeter = 2(length + width) = 2(7 + 12) = 38 cm

Answer:

The correct options are 1, 2, 3 and 4.

Step-by-step explanation:

The given function is

[tex]f(x)=2^x[/tex]

The above function is defined for all the values of x.

⇒ Therefore the domain is all real numbers x because the exponent of 2 can be any real number.

⇒ The x is exponent of 2, therefore the x-values increases by 1 unit, the y-value multiplies by 2.

Put x=0, to find the y-intercept.

[tex]f(x)=2^=1[/tex]

⇒The y-intercept is (0, 1).

The value of f(x) is always greater than 0 because powers of 2 are never negative.

[tex]f(x)>0[/tex]

⇒The graph never goes below the x-axis because powers of 2 are never negative.

⇒Therefore the range of the function is all positive real numbers.

Therefore the correct options are 1, 2, 3 and 4.

The True statements about the graph of the function [tex]y =2^x[/tex] are option a), b), c) and d). Refer the below solution for better understanding.

Given :

[tex]y = 2^x[/tex]

Solution :

Step-by-step explanation:

12/3.48= cost of 1 book

cost of 20 books = 12/3.48×20 =68.95

To find the cost of 20 pens when 12 pens cost $3.48, divide $3.48 by 12 to get the cost per pen and then multiply by 20. The cost for 20 pens would be $5.80.

To calculate the cost of 20 pens when 12 pens cost $3.48, first, we need to find the cost of one pen. We do this by dividing the total cost of 12 pens by the number of pens:

$3.48 / 12 pens = $0.29 per pen.

Now that we know the cost of one pen, we can calculate the cost of 20 pens by multiplying the cost per pen by 20:

$0.29 / pen x 20 pens = $5.80.

So, 20 pens would cost $5.80.

Answer:

SA = 124 cm²

Step-by-step explanation:

The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.  

93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area

The surface area of the tetrahedron is 124 square centimeters.

Let's denote the surface area of one equilateral triangle as A The total surface area of the tetrahedron, which includes all four faces, is then  4A.

 Given that the lateral surface area (which is three faces) is 93 square centimeters, we can write:

 3A = 93

To find the area of one face (A), we divide both sides by 3:

[tex]\[ A = \frac{93}{3} = 31 \][/tex]

Now, to find the total surface area of the tetrahedron, we multiply the area of one face by 4:

[tex]\[ \text{Total Surface Area} = 4A = 4 \times 31 = 124 \][/tex]

Therefore, the surface area of the tetrahedron is 124 square centimeters.

Step-by-step explanation:

Answer:

[tex]m\angle YPL=65^{\circ}[/tex]

Step-by-step explanation:

We have been given an image of a circle and we are asked to find the measure of angle YPL.

Since the degree measure of circumference of a circle is 360 degrees, so we can set an equation to find the measure of arc LY as:  

[tex]m\widehat{LY}+m\widehat{PL}+m\widehat{PY}=360^{\circ}[/tex]

Upon substituting our given values in above equation we will get,

[tex]m\widehat{LY}+80^{\circ}+150^{\circ}=360^{\circ}[/tex]

[tex]m\widehat{LY}+230^{\circ}-230^{\circ}=360^{\circ}-230^{\circ}[/tex]

[tex]m\widehat{LY}=130^{\circ}[/tex]

We can see that angle YPL is inscribed angle of arc LY, so the measure of angle YPL will be half the measure of arc LY.

[tex]m\angle YPL=\frac{1}{2}m\widehat{LY}[/tex]

[tex]m\angle YPL=\frac{1}{2}\times130^{\circ}[/tex]

[tex]m\angle YPL=65^{\circ}[/tex]

Therefore, the measure of angle YPL is 65 degrees.

2*10^-5 = 2*00001 = 0.00002

Answer: The sales tax rate is 5%.

Step-by-step explanation: In order to calculate the sales tax rate you need to divide the amount of sales tax by the amount of the purchase. In this case you divide .20 by $4.00. .2 / 4 = .05 = 5% sales tax rate

The sales tax rate for a pack of cinnamon-scented pencils that sells for $4.00 and totals $4.20 is 5%.

To calculate the sales tax rate for a pack of cinnamon-scented pencils that sells for $4.00 and has a total cost of $4.20 including tax, you first need to find the amount of sales tax paid. The sales tax paid is the difference between the total cost and the sale price, which is

$4.20 - $4.00 = $0.20.

Next, you convert the sales tax amount to the sales tax rate by dividing the tax amount by the original price and then multiplying by 100 to get a percentage. Therefore, the sales tax rate is

($0.20 / $4.00) x 100, which equals 5%. The packed pencils had a 5% sales tax added to the original price.

Answer:

I am not sure that this is a solvable equation.

The question involves predicting the temperature of water after six intervals using an exponential decay function. Without the exact values to form the function, we can infer that the temperature will likely be around option (b) 101°F after six intervals based on the pattern of decrease shown in the provided intervals.

The student's question is about using an exponential function to model the temperature decrease of water as it cools at room temperature.

To solve this problem, one would generally apply the formula for an exponential decay function, which is of the form w(t) = [tex]a * e^{(kt)[/tex], where w(t) is the temperature at time t, a is the initial temperature, e is the base of the natural logarithm, and k is the decay constant. Given the temperatures at specific intervals, one could use these to estimate the constants a and k.

However, without the necessary values to develop an equation, we instead look for the pattern in the temperature's decrease to predict the sixth interval's approximate temperature.

Examining the table provided:

We can see that the temperature is decreasing less with each interval. While it is not explicitly stated, it's reasonable to assume that an exponential decay function would fit this scenario. Without the exact function, we can make an educated guess based on the trend that after six intervals, the temperature will be less than 121°F and likely close to option (b) 101°F.

Step-by-step explanation:

115+10x = y

After 7 trips to the fair, Erin has 185 stamps in her collection according to to the equation y = 115 + 10x.

To find out how many stamps Erin has after 7 trips to to the fair, we can use the given equation:

[tex]\[ y = 115 + 10x \][/tex]

where:

- [tex]\( y \)[/tex] represents the number of stamps in Erin's collection.

- [tex]\( x \)[/tex] represents the number of times Erin has been to to the stamp fair.

Substituting [tex]\( x = 7 \)[/tex] into the equation, we get:

[tex]\[ y = 115 + 10(7) \][/tex]

[tex]\[ y = 115 + 70 \][/tex]

[tex]\[ y = 185 \][/tex]

So, after 7 trips to the fair, Erin has [tex]\( 185 \)[/tex] stamps in her collection.

x squared and -9 are both square numbers.

the square root of x^2 is x

the square root of -9 is 3. so you just need to write (x+3)(x-3)

you can check by expanding the brackets and the middle x terms should cancel out

Answer:

(x-3)(x+3)

Step-by-step explanation:

Here we have to represent our algebraic expression as difference of square.

In order to do so we have use the formula given under.

[tex](x^2-a^2)=(x-a)(x+a)[/tex]

Hence first we have to guess the square root of the 9 , which is 3 and represent our numeric term in our expression as square of it.

Hence

[tex](x^2-9)\\= (x^2-3^2)[/tex]

Now we apply the formula

[tex](x^2-3^2)=(x-3)(x+3)[/tex]

Hence the above expression is our answer.
