Answer:

20 harnesses

36 leashes

Step-by-step explanation:

h = number of harnesses

l = number of leashes

set up two equations based on the information provided:

h + l = 56; since the number of harnesses and leashes made up the total item sold, which is 56

7.5h + 3.25l = 267; the same concept as the last step

h = 56 - l; let one of the variable stand by itself

7.5(56 - l) + 3.25l = 267; substitute the variable h into the other equation

420 - 7.5l + 3.25l = 267; solve

420 - 4.25l = 267; add common variables, remember you take the sign in front of the number when doing math

-4.25l = -153; subtract 420 from both side

l = 36; divide both side by -4.25

36 leashes were sold last month; 56 - 36 = 20, which means 20 harnesses were sold.

The expression [tex]\frac{7\sqrt{x^2}}{5\sqrt{y^3}}[/tex] can be simplified to  [tex]\frac{7\sqrt{x^2}}{5y\sqrt{y}}[/tex].

Let's simplify the expression [tex]\frac{7\sqrt{x^2}}{5\sqrt{y^3}}[/tex]:

First, simplify the square root terms:

[tex]\frac{7|x|}{5\sqrt{y^3}}[/tex]

Now, combine the constants:

[tex]\frac{7}{5} \cdot \frac{|x|}{\sqrt{y^3}}[/tex]

To simplify further, you can rewrite [tex]\sqrt{y^3}[/tex] as [tex]\sqrt{y^2 \cdot y}[/tex] and then cancel out one of the y terms:

[tex]\frac{7}{5} \cdot \frac{|x|}{y\sqrt{y}}[/tex]

So, the simplified expression is [tex]\frac{7|x|}{5y\sqrt{y}}[/tex], or equivalently, [tex]\frac{7\sqrt{x^2}}{5y\sqrt{y}}[/tex].

5 gallons, 24 quarts (6 gallons), 10.6 gallons

To arrange 5 gallons, 10.6 gallons, and 24 quarts from smallest to largest, first convert all measurements into the same unit (quarts). The arrangement from smallest to largest is 5 gallons, 24 quarts, and 10.6 gallons.

To arrange the given measurements of 10.6 gallons, 5 gallons, and 24 quarts from smallest to largest, we first need to convert them into the same unit for an accurate comparison. Given the conversion factor of 1 gallon equals 4 quarts, we can start the comparison process.

In quarts, the order from smallest to largest is as follows: 20 quarts (5 gallons), 24 quarts, and 42.4 quarts (10.6 gallons). Therefore, when we arrange the original units from smallest to largest, it will be 5 gallons, 24 quarts, and then 10.6 gallons.

Answer:

The volume ratio of Prism A to Prism B is [tex]\frac{729}{8}[/tex]

Step-by-step explanation:

Step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z-----> scale factor

x/y----> ratio of the surface area of Prism A to Prism B

so

[tex]z^{2}=\frac{x}{y}[/tex]

we have

[tex]\frac{x}{y}=\frac{81}{4}[/tex]

substitute

[tex]z^{2}=\frac{81}{4}[/tex]

[tex]z=\frac{9}{2}[/tex]

step 3

Find the volume ratio of Prism A to Prism B.

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> scale factor

x/y----> volume ratio of Prism A to Prism B

so

[tex]z^{3}=\frac{x}{y}[/tex]

we have

[tex]z=\frac{9}{2}[/tex]

substitute

[tex](\frac{9}{2})^{3}=\frac{x}{y}[/tex]

[tex](\frac{729}{8})=\frac{x}{y}[/tex]

The volume ratio of two similar prisms with a surface area ratio of 81:4 is obtained by cubing the square root of the surface area ratio, resulting in a volume ratio of 729:8.

The question involves finding the volume ratio of two similar prisms when the surface area ratio is given.

Since the surface areas are in a ratio of 81:4, the corresponding linear dimensions will be in the square root ratio, which is 9:2. For two similar three-dimensional shapes, if the ratio of their corresponding lengths is a:b, then the ratio of their surface areas is a^2:b^2, and the ratio of their volumes is a^3:b^3.

Therefore, the volume ratio of Prism A to Prism B can be found by cubing the linear dimension ratio: (9:2)^3 which equals 729:8. Hence, the volume ratio of Prism A to Prism B is 729:8.

The circle has circumference [tex]18\pi\,\mathrm{in}[/tex]. If [tex]m\angle POQ=\theta[/tex], then

[tex]\dfrac{6\pi\,\rm in}{18\pi\,\rm in}=\dfrac\theta{2\pi\,\rm rad}\implies\theta=\dfrac{2\pi}3\,\mathrm{rad}[/tex]

Answer: [tex]\dfrac{2\pi}{3}\text{ radians}[/tex]

Step-by-step explanation:

We know that the formula to calculate the length of arc having central angle 'x' is given by :-

[tex]l=x r[/tex], where r is radius of the circle.

Given : In circle O, radius OQ = [tex]l=9\text{ inches}[/tex]

The measure of arc PQ =[tex]6\pi\text{ inches.}[/tex]

The measure of central angle POQ ( in radians ) is given by :-

[tex]x=\dfrac{l}{r}\\\\\Rightarrow\ x=\dfrac{6\pi}{9}}\\\\\Rightarrow\ x=\dfrac{2\pi}{3}[/tex]

Hence, the measure of central angle POQ =[tex]\dfrac{2\pi}{3}\text{ radians}[/tex]

Answer: Third option

[tex]-x + 2 = 3x - 4.[/tex]

Step-by-step explanation:

One of the ways of solving a system of equations is by equating the equations and solving for one of the variables.

In this case we have the system:

[tex]y = -x + 2\\\\y = 3x - 4[/tex]

Note that if [tex]y[/tex] is equal [tex]-x + 2[/tex] and also [tex]y[/tex] equals [tex]3x - 4[/tex]

Then logically [tex]-x + 2[/tex] must be equal to [tex]3x - 4[/tex].

We write equality.

[tex]-x + 2 = 3x - 4.[/tex]

Then the correct answer is the third option.

We can also solve for the variable x

[tex]-4x = -6\\\\4x = 6\\\\x = \frac{6}{4}\\\\x = \frac{3}{2}[/tex]

Answer:

A∩B={[tex]25, 45, 65[/tex]}

B is a proper subset of A:

Step-by-step explanation:

A∩B means the intersection of the set A and the set B. In other words, is the set of elements contained in these both sets.

Given the set A and the set B:

[tex]A =[/tex]{[tex]15, 25, 35, 45, 55, 65[/tex]}

[tex]B =[/tex]{[tex]25, 45, 65[/tex]}

You can indentify that the numbers common in both sets are: 25,45 and 65.

Therefore you get:

A∩B={[tex]25, 45, 65[/tex]}

Since all elements of B are in A, and A contains elements that are not in B, then B is a proper subset of A:

B⊂A

10 mm = 1 cm.

Divide total mm by 10 to get total cm's.

500/10 = 50 centimeters.

500/10 = 50

The answer here is 50 cm

For this case we must simplify the following expression:

[tex](x ^ {\frac {3} {8}}) ^ {\frac {3} {4}}[/tex]

By definition of power properties we have to:

[tex](a ^ m) ^ n = a ^ {m * n}[/tex]

So, rewriting the expression we have:

[tex](x ^ {\frac {3} {8}}) ^ {\frac {3} {4}} = x ^ {\frac {9} {32}}[/tex]

ANswer:

[tex]x ^ {\frac {9} {32}}[/tex]

The simplified value of the expression [tex]\((\frac{x^3}{8})^\frac{3}{4}\)[/tex] is [tex]\(\frac{x^\frac{9}{4}}{2^\frac{9}{4}}\).[/tex]

To simplify the expression [tex]\((\frac{x^3}{8})^\frac{3}{4}\)[/tex] using the laws of exponents,

combine the exponents and simplify the fraction.

So, [tex]\((\frac{x^3}{8})^\frac{3}{4}\)[/tex] can be written as [tex]\(\frac{x^{3 \cdot \frac{3}{4}}}{8^\frac{3}{4}}\)[/tex].

Next, simplify the exponents:

[tex]\(3 \cdot \frac{3}{4} = \frac{9}{4}\).[/tex]

So, the expression [tex]\(\frac{x^{3 \cdot \frac{3}{4}}}{8^\frac{3}{4}}\)[/tex]can be written as [tex]\(\frac{x^\frac{9}{4}}{8^\frac{3}{4}}\)[/tex].

To further simplify, express 8 as  [tex]\(2^3\)[/tex]:

So, [tex]\(\dfrac{x^\dfrac{9}{4}}{8^\dfrac{3}{4}} = \dfrac{x^\dfrac{9}{4}}{(2^3)^\dfrac{3}{4}}\).[/tex]

Now, applying the property [tex]\((a^m)^n = a^{m \cdot n}\)[/tex]:

[tex]\(\dfrac{x^\dfrac{9}{4}}{(2^3)^\dfrac{3}{4}} = \dfrac{x^\dfrac{9}{4}}{2^{3 \cdot \frac{3}{4}}}\).[/tex]

Simplifying the exponent [tex]\(3 \cdot \frac{3}{4} = \frac{9}{4}\)[/tex]:

[tex]\(\frac{x^\frac{9}{4}}{2^{3 \cdot \frac{3}{4}}} = \frac{x^\frac{9}{4}}{2^\frac{9}{4}}\).[/tex]

Therefore, the simplified value is  [tex]\(\frac{x^\frac{9}{4}}{2^\frac{9}{4}}\).[/tex]

You are given the two legs (40 and 9) which you will plug into a and b. That means that you have to find c, the hypotheses

40^2 + 9^2 = c^2

1600 + 81 = c^2

1681 = c^2

To get rid of the squared on the c, square root both sides:

41 = c

Hope this helped!

Answer: The missing length is 41m

Step-by-step explanation:

To find the missing length c, we simply use the Pythagoras thereon.

The Pythagoras theorem states that: in a right-angle triangle,

opposite²   +  adjacent² =  hypotenuse²

In this case

opposite = 40

adjacent = 9

hypotenuse = c (It is the missing length)

Applying the Pythagoras theorem to this;

opposite²   +  adjacent² =  hypotenuse²

          40²    +     9²       =      c²

We will now go ahead and simplify

40²    +     9²       =      c²

        1600    +    81      =  c²

        1681      =  c²

To get the value of c, we will simply take the square root of both-side

√ 1681      = √ c²

      41    =   c

Therefore the missing length is 41 m

Long division (in diagram)

Final answer:

The volume of a cone with a diameter of 6 inches and a height of 6 inches is approximately 56.5 cubic inches when rounded to the nearest tenth, using the volume formula for a cone.

Explanation:

To calculate the volume of a cone, we can use the formula

V = [tex]\(\frac{1}{3}\)\pi r^2 h[/tex]

First, find the radius (r) by dividing the diameter by 2.

The cone's diameter is 6 inches, thus the radius[tex]\(r = \frac{6}{2} = 3\) inches.[/tex]

Next, apply the values to the cone volume formula:

V =[tex]\(\frac{1}{3}\)\pi (3)^2 \times 6\)[/tex]

Now perform the calculations

V = [tex]\(\frac{1}{3}\)\times 3.14 \times 9 \times 6[/tex]

V = 56.52 cubic inches

Therefore, the volume of the cone is approximately 56.5 cubic inches to the nearest tenth.

Answer:

x² + 2x + (3 / (x − 1))

Step-by-step explanation:

Start by setting up the division:

.........____________

x − 1 | x³ + x² − 2x + 3

Start with the first term, x³.  Divided by x, that's x².  So:

.........____x²______

x − 1 | x³ + x² − 2x + 3

Multiply x − 1 by x², subtract the result, and drop down the next term:

.........____x²______

x − 1 | x³ + x² − 2x + 3

.........-(x³ − x²)

...........----------

...................2x² − 2x

Repeat the process over again.  First term is 2x².  Divided by x is 2x.  So:

.........____x² + 2x __

x − 1 | x³ + x² − 2x + 3

.........-(x³ − x²)

...........----------

...................2x² − 2x

Multiply, subtract the result, and drop down the next term:

.........____x² + 2x __

x − 1 | x³ + x² − 2x + 3

.........-(x³ − x²)

...........----------

...................2x² − 2x

.................-(2x² − 2x)

.................---------------

.....................................3

x doesn't divide into 3, so that's the remainder.

Therefore, the answer is:

x² + 2x + (3 / (x − 1))

8 & 4 when you add them together it’s 12 and when you multiply then it’s 32. When you see sum in a problem it means add. When you see product in a problem it means multiply.

the bonds of 12, (of which there are 7 pairs)

(which pairs of numbers add up to 12?)

or the factors of 32 (of which there are 3 pairs)

Using the factors seems quicker.

Write the factors and in each find their sum.

As 12 is quite small in comparison to 32, I would expect that the middle factors will be the ones we want - they have the smallest sum and the smallest difference of all the pairs:

Because some applicants volunteer and meet the GPA requirements the events are NOT MUTUALLY exclusive. Thus, the probability is 65%

The probability that an applicant meets the GPA requirements or volunteers is 65%.

To find the probability that an applicant meets the GPA requirements or volunteers, we need to determine the number of applicants who meet either requirement. From the given information, there are 950 applicants who meet the GPA requirements and 600 applicants who volunteer for community service. However, there are 250 applicants who meet both requirements, so we count them only once.

To find the total number of applicants who meet either requirement, we add the number of applicants who meet the GPA requirements and the number of applicants who volunteer and subtract the number of applicants who meet both requirements:

Total number of applicants who meet either requirement = 950 + 600 - 250 = 1300

The probability that an applicant meets the GPA requirements or volunteers is the number of applicants who meet either requirement divided by the total number of applicants:

Probability = Number of applicants who meet either requirement / Total number of applicants = 1300 / 2000 = 0.65 = 65%

Answer:

Length = 17 inches, Width = 14 inches

Step-by-step explanation:

Let the width(W) of the rectangle be x inches

The length(L) of the rectangle will be x + 3 inches

Perimeter(P) of the rectangle is 62 inches

i.e

P = 2L + 2W

2(x + 3) + 2x = 62

2x + 6 + 2x = 62

4x = 62 - 6 = 56

x = [tex]\frac{56}{4}[/tex] = 14 inches

So the width is 14 inches and;

The length is 14 + 3 = 17 inches

The width of the rectangle is 14 inches, and the length is 17 inches.

To find the length and width of a rectangle, we can use the information given in the problem and set up an equation. Let's say the width of the rectangle is x inches. The length would then be x + 3 inches. The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Plugging in the given values for the perimeter, we get:

62 = 2(x + 3) + 2x

Simplifying the equation:

62 = 2x + 6 + 2x

Combine like terms:

62 = 4x + 6

Subtract 6 from both sides:

56 = 4x

Divide both sides by 4:

x = 14

So the width of the rectangle is 14 inches. Substituting this value back into the equation for the length, we get:

Length = 14 + 3 = 17 inches
