A cube has a volume of 1000 cubic feet. What is the length of an edge of the cube?

Answer:

Step-by-step explanation:

This sort of problem is easily solved by defining a variable to be the quantity of the higher-value contributor. Here, we can let x represent the number of adult tickets. Then total revenue is ...

  6.50x +3.50(548-x) = 2881

  3x +1918 = 2881 . . . . . . . . . . . . eliminate parentheses, collect terms

  3x = 963 . . . . . . . . . . . . . . . . . . subtract 1918

  x = 321 . . . . . . . . . . . . . . . . . . . . divide by 3

  548-x = 548 -321 = 227 . . . . . .number of child tickets

321 adult tickets and 227 child tickets were sold.

By setting up and solving a system of equations, it was determined that the theater sold 320 adult tickets and 228 child tickets.

Let's denote the number of adult tickets as A and the number of child tickets as C.

The first piece of information given is:

Total tickets sold: A + C = 548

The second piece of information is related to the total revenue:

Total revenue from tickets: 6.50A + 3.50C = 2881

To find the values of A and C, we can use the substitution or elimination method to solve this system of equations. Here, we'll use the elimination method:

Multiply the first equation by 3.50 to align the coefficients of C with the second equation:

Subtract this new equation from the second equation to eliminate C:
Substitute A = 320 into the first equation to solve for C:
Therefore, the theater sold 320 adult tickets and 228 child tickets.

The graph of the function starts high and ends high.

Answer: Option B.

Explanation:

The end conduct of a graph is characterized as what is happening at the parts of the bargains. As the capacity approaches positive or negative infinity, the main term figures out what the diagram resembles as it moves towards vastness.

The end conduct of a chart is the way our capacity carries on for extremely huge and tiny info esteems. For exponential capacities, we see that our end conduct goes to endlessness as our information esteems get bigger. The bigger the base of our exponential capacity, the quicker the development.

The end behavior of the function F(x) = 2x^4 + x^3 is determined by the term 2x^4. As x tends toward both positive and negative infinity, this term causes the function to increase towards infinity, meaning the graph starts low and ends high.

The question asks about the end behavior of the polynomial function F(x) = 2x^4 + x^3. To determine this, we look at the highest degree term, which dominates the end behavior. In this case, that term is 2x^4.

As x approaches positive infinity, 2x^4 will grow very large, so the function will also go towards infinity. Similarly, as x approaches negative infinity, 2x^4 will still grow very large (since an even power of a negative number is positive), and the function will go towards infinity as well. Thus, the graph of the function starts low when x is very negative and ends high as x becomes very positive.

Therefore, the correct answer to the student's question is Option A: The graph of the function starts low and ends high.

Answer:

The coordinates of B are (7.67,12)

Step-by-step explanation:

Let the coordinates of B are (h,k).

Now, point P(3,6) partitions AB into a ratio of 3 : 2 and A is found at (-4,-3).

We have to find B(h,k).

Now, from the formula of coordinate geometry we have,

[tex]3 = \frac{2(- 4) + 3h}{3 + 2}[/tex]

⇒ 3h - 8 = 15

⇒ 3h = 23

⇒ h = 7.67

And, [tex]6 = \frac{2(- 3) + 3k}{2 + 3}[/tex]

⇒ 3k - 6 = 30

⇒ 3k = 36

⇒ k = 12

Therefore, the coordinates of B are (7.67,12) (Answer)

∴ The multiples of nine are 9, 18, 27, 36, 45, 54, 63, .....

Thus, the multiples of nine are 9, 18, 27, 36, 45, 54, 63, ..... .

Answer:

The measure of 'x' is 6 units.

Step-by-step explanation:

Given:

An isosceles triangle.

The two equal arms length = [tex]\sqrt{13}[/tex]

Measure of the altitude = [tex]2[/tex]

Note:The altitude to the base of an isosceles triangle bisects the base.

         The altitude also forms 90 degree at the base.

So, the base length can also be seen as 'x' which we can also be written as [tex]x=\frac{x}{2} +\frac{x}{2}[/tex]

And [tex]\frac{x}{2}[/tex] is a part of the right angled triangle.

Where hypotenuse = [tex]\sqrt{13}[/tex]

Perpendicular length =[tex]2[/tex]

Base length = [tex]\frac{x}{2}[/tex]

Now,

From Pythagoras formula we know that:

[tex](hypotenuse)^2 =(perpendicular)^2+ (base)^2[/tex]

Plugging the values:

⇒  [tex](hypotenuse)^2 - (perpendicular)^2 = (base)^2[/tex]

⇒  [tex]\sqrt{ (hypotenuse)^2 - (perpendicular)^2} = (base)[/tex]

⇒  [tex]\sqrt{(\sqrt{13})^2-(2)^2} =\frac{x}{2}[/tex]

⇒ [tex]\sqrt{13-4}=\frac{x}{2}[/tex]

⇒ [tex]\sqrt{9} =\frac{x}{2}[/tex]

⇒ [tex]3=\frac{x}{2}[/tex]

⇒ [tex]3\times 2=x[/tex]

⇒ [tex]6 = x[/tex]

So the value of base 'x' = 6 units.

Answer:

[tex]T_{59}= 493[/tex]

Step-by-step explanation:

Given:

Arithmetic sequence

29, 37, 45............

n = 59

We need to find the 59 term of the arithmetic sequence.

Solution:

Using formula for nth term of arithmetic sequence.

[tex]T_{n}= a + (n-1)d[/tex] -------------(1)

Where:

a = first term of the sequence.

d = Common difference.

first find the the common difference of .

[tex]d = a_{2}-a_{1}[/tex]

[tex]d=37-29[/tex]

d = 8

Substitute a = 29, d = 8 and n = 59 in equation 1.

[tex]T_{59}= 29 + (59-1)8[/tex]

[tex]T_{59}= 29 + 58\times 8[/tex]

[tex]T_{59}= 29 + 464[/tex]

[tex]T_{59}= 493[/tex]

Therefore, 59th term of the arithmetic sequence [tex]T_{59}= 493[/tex]

Answer:

[tex]\frac{11}{14}[/tex]

Step-by-step explanation:

Total number of marbles = 4+3+2+5=14

number of not red marbles = 4+2+5=11

then

the probability that she picked a marble that is not red = 11/14

To find the length of the missing side, you can use the Pythagorean Theorem, which you can only use for right triangles.

Pythagorean Theorem:  a² + b² = c²

[ c is the hypotenuse or the longest side of the triangle, and a and b are the other sides, I think it doesn't matter which side ]

Plug in what you know:

b = 8

c = 14

a² + b² = c²

a² + (8)² = (14)²

a² + 64 = 196       Subtract 64 on both sides

a² = 132       Square root both sides to get "a" by itself

[tex]\sqrt{a^2} =\sqrt{132}[/tex]

a = [tex]\sqrt{132}[/tex] inches

If you need to simplify more, you need to find two numbers that multiply to = 132 where one of them can be square rooted, to do so you can list the greatest common factors of 132

132: 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

The only number that can be square rooted is 4, so you can do:

[tex]a=\sqrt{4*33}[/tex]

[tex]a=\sqrt{4} *\sqrt{33}[/tex]

[tex]a=2\sqrt{33}[/tex]

Answer:

16x2y2 + 9z2 (They are a perfect square trinomial.

Step-by-step explanation:

The proportion that could be used to solve for the variable is:

[tex]\frac{16}{40} = \frac{3}{h}[/tex]

h = 7.5

Solution:

Given that,

16 walls in 40 hours 3 walls in h hours

Which means,

16 walls build in 40 hours

Then 3 walls in h hours

We have to write a proportion

The number of walls and the number of hours are proportion

Therefore, we get,

[tex]\frac{16}{40} = \frac{3}{h}[/tex]

Cross multiply and solve for h

[tex]16 \times h = 3 \times 40\\\\16h = 120\\\\h = \frac{120}{16}\\\\h = 7.5[/tex]

Thus the proportion is solved

Step-by-step explanation:

[tex]357 \: m = 3.57 \times {10}^{2} \: m[/tex]

The wavelength of the radio wave in scientific notation is 3.57 x 10^2 m.

The wavelength of a radio wave is given as 357 m. Since this is already a simple number, converting it to scientific notation would be 3.57 x 102 m. Here, '3.57' is the significant part of the number (the significand) and '2' is the power to which 10 is raised (the exponent). In scientific notation, we aim to express numbers between 1 (inclusive) and 10 (exclusive).

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Answer:

 The required function that models the number of branches t years since Bela began studying her tree is

number of branches = [tex]60(1.83)^{\frac{t}{2.9} }[/tex]

Step-by-step explanation:

Let t be the time in years

Initially Bela's tree had 60 branches.

therefore the function that can be used to model the number of branches after t years will be given by

number of branches( after t years) [tex]= 60\times(1 + \frac{83}{100})^{\frac{t}{2.9} } = 60(1.83)^{\frac{t}{2.9} }[/tex]

The function model is  [tex]B(t) = 60 * (1.83)^{\frac{t}{2.9}}[/tex].

To model the growth of branches on Bela's tree over time, we can use an exponential growth function. Given that the number of branches increases by 83% every 2.9 years, and the initial number of branches is 60, the function can be derived as follows:

The growth factor after each period of 2.9 years can be expressed as 1 + 0.83 = 1.83. If we let t represent the time in years, we need to determine how many 2.9-year periods have passed. This is given by  [tex]\frac{t}{2.9}[/tex].

Thus, the function modeling the number of branches, B(t), after t years is:

[tex]B(t) = 60 * (1.83)^{\frac{t}{2.9}}[/tex]

This function accounts for the exponential growth of the number of branches on Bela's tree over time.

The worth of boat after 11 years is $ 3159.3013

Solution:

Given that,

Boat costs $16600 and decreased in value by 14% per year

To find: Worth of boat after 11 years

The formula for decreasing function is given as:

[tex]y = a(1-r)^t[/tex]

Where,

y is the value after "t" years

t is the number of years

a is the initial value

r is decreasing rate in decimal

From given,

a = 16600

t = 11

[tex]r = 14 \% = \frac{14}{100} = 0.14[/tex]

Substituting the values we get,

[tex]y = 16600(1-0.14)^{11}\\\\y = 16600(0.86)^{11}\\\\y = 16600 \times 0.1903\\\\y = 3159.3013[/tex]

Thus the worth of boat after 11 years is $ 3159.3013

Perpendicular means negative reciprocal of the current slope.

And the negative reciprocal of -2 is 1/2.

To form a triangle The sum of any two length must be greater the the third side.

5+ 6 =11, which is less than 12 so it can’t form a triangle

The sides 5, 6, and 12 form a triangle is false. C will always be the biggest number because it is the hypotenuse, and the others numbers can either be A or B.

Answer: d=$12, b=$1

d represents DVDs

b represets books

Step-by-step explanation:

Whenever you have 2 examples of 2 different things (such as books and dvds), make a systems of equations.

Step 1: Write a system of equations

3d+4b=  40

d+6b= 18

Step 2: Eliminate any letter. I'll just choose d.

To elimiate d, you have to make them both equal to the biggest d variable. In other words, make both d terms equal to 3d. To do this, miultiply the 2nd equation by 3, and keep the 1st one the same.

3d+4b=40

3d+18b= 54

Now, elimiate d, by doing 3d-3d= 0. Now use subtraction to solve for b since we used this to get 3 and 3 to 0.

4b-18b=40-54

-14b= -14

b= -14÷-14

b= 1

Each book costs 1 dollar.

Step 3: Plug in b=1 to find how much each dvd costs (plug into any equation)

3d+4b=40

3d+4(1)=40

3d+4=40

3d=40-4

3d=36

d=36÷3

d=12

Each dvd is $12

Step 4:  Checks--plug d=12 and b=1 into any equation

3d+4b=40

3(12)+4(1)=40

36+4=40

40=40

Answer:

D

Step-by-step explanation:

When something is forgoing a transformation that stays congruent, if it is rotating, it is simply turning a given amount of degrees: if it is translating, it is simply move up/down or right/left on the x and y axis; and finally, if it reflects, it is simply being inverted across either the x or y axis. None of these transformations result in changing the shape and/or size of the triangle.

Final answer:

The possible transformation that could have taken place is either a reflection, a rotation, or a translation, as they all preserve the congruency of the original triangle. Option D is correct.

Explanation:

If triangle XYZ is transformed to form triangle X'Y'Z' and the image is congruent to the original triangle, then the transformation could be a reflection, a rotation, or a translation. Congruent transformations are those that preserve the size and shape of a figure. Since the original triangle is congruent to its image after the transformation, we can conclude that the transformation is one that preserves congruency. Reflections across a line, rotations about a point, and translations (which slide a figure) all preserve the size and shape of the figure, and hence the triangles would remain congruent after any of these transformations.

Step-by-step explanation:

The domain of the function y = √x + 4 is all real numbers x such that x ≥ 0, because the square root of a negative number is not a real number in the set of real numbers.

The given function is y= x +4. The square root function x  is defined only for non-negative values of x. This is because the square root of a negative number is not a real number in the real number system.

Therefore, for the given function to be defined, the expression inside the square root (x) must be greater than or equal to zero. Mathematically, this condition is expressed as:x≥0

This inequality ensures that the square root is always defined for any real number x in the domain of the function.

So, the domain of the function y= x +4 is all real numbers x such that  x≥0. In interval notation, this can be expressed as [0,∞).

Answer: Shoebuy.com

Step-by-step explanation:

20% of $49.00 is $9.8. When you subtract $9.80 from $49, you end up with $39.2. Now to look at Crocs.com, in order to get the total, add the price of the shoes, $35 and the shipping cost, $4.30, you'll end up with $39.30. Because Shoebuy is $.10 less than Crocs.com, it is the better choice.

After calculating the total costs, purchasing the Crocs from Shoebye.com with the 20% discount and free shipping comes out to be cheaper by $0.10 than buying them on sale at Crocs.com with added shipping and handling.

Mr. Walker is trying to determine the better buy for a new pair of Crocs. The comparison involves a 20% discount and free shipping at Shoebye.com versus sale price with additional shipping and handling at Crocs.com.

Calculation at Shoebye.com:

Original price: $49.00

Discount (20% of $49): $9.80

Discounted price: $49 - $9.80 = $39.20

Shipping: $0 (free)

Total cost at Shoebye.com: $39.20

Calculation at Crocs.com:

Sale price: $35.00

Shipping and handling: $4.30Total cost at Crocs.com: $35.00 + $4.30 = $39.30

Comparing both totals, Shoebye.com's offer of $39.20 is slightly better than Crocs.com's offer of $39.30. Thus, purchasing from Shoebye.com would save Mr. Walker $0.10.
