Step-by-step explanation:

You are supposed to find the volume.

To do this, find the volume of the green figure and blue(ish) figure separately and then add them together.

For volume, it is

length times width times height

[tex]l*w*h[/tex]

it doesn't matter what you say is length or height or whichever.

so let's do green

12 * 12 * 6

12*12 is gross aka 144

then 144*6 is... 864

The volume of the green figure is 864 cubic inches.

Now let's find the blue(ish) figure.

18 * 8 * 10

that equals 1,440 (calculator)

The volume of the blue(ish) figure is 1,440 cubic inches.

Now add the two volumes together.

1,440+864 = 2304

Answer:

Answer D

Step-by-step explanation:

Number of hours, 3

Cost: 105

divide 105 by 3 = 35

35 = cost of boat for 1 hour

so the answer is D :)

C = 35h

C = cost

H = hours

:)

Answer:

D. C = 35h

Step-by-step explanation:

105/3 = 35

that means it cost $35 an hour to rent the boat

so 35 x number of hours you rent = total cost

which is C = 35h

The sum of the first 11 terms of the geometric sequence aₙ = 2aⁿ - 1 with an initial value of a₁ = 1/8 is -10.71.

Therefore the answer is -10.71.

The geometric sequence aₙ = 2aⁿ - 1 with an initial value of a₁ = 1/8 represents the amount of money saved after n years of investing.

So sum of n terms

Sn = 2a - 1 + 2a² - 1 + ... + 2aⁿ - 1

Sn = 2( a + a² + ... + aⁿ) - n

The sum of the first n terms of a geometric sequence aₙ = arⁿ⁻¹ with first term a₁ and common ratio r is given by the formula:

Sn = a₁(1 - rⁿ)/ (1 - r), that is

[tex]S_{n} = a_{1}\frac{ (1 - r^n)}{1 - r}[/tex]

So a + a² + ... + aⁿ = a(1 - aⁿ)/ (1 - a)

Thus Sn = 2( a + a² + ... + aⁿ) - n

Sn = 2a(1 - aⁿ)/ (1 - a) - n

In this case, a₁ = a = 1/8 and n = 11

So the sum of the first 11 terms of the geometric sequence is:

Sn = 2×1/8×( 1 - (1/8)¹¹)/ (1 - 1/8) - 11

Sn = -10.71

280t + 320t = 1,000 is distance equation can be used to solve for t, the time it takes the planes to be 1,000 miles apart.

What does distance mean in a nutshell?

Distance is the overall movement of an object without consideration of direction.

                      Regardless of an object's starting or ending point, distance can be defined as the amount of ground it has traveled.

At 10:00 a.m. two planes leave an airport. If the northbound plane flies at 280 mph and the southbound at 320 mph

Let 't' be the time taken when they are 1000 miles apart

the northbound plane flies at 280 mph

Distance  = speed * time

distance covered by northbound plane D1= 280 * t= 280t

the southbound at 320 mph

distance covered by southbound plane D2=320 t

Distance is 1000 miles apart

D1 + D2= 1000

280t + 320t = 1,000

The y - intercept of the graph, given the formula of 2 y - 5x = 16, is y - intercept : ( 0, 8)

To find the y - intercept, use the slope - intercept form of the equation of a line which is:

y = mx + b

m = slope

b = y - intercept

So first rewrite the formula given to look like the slope - intercept :

2 y - 5x = 16

2 y = 5x + 16

( 2 y = 5x + 16 ) / 2

y = 5/ 2 x + 8

The y- intercept is therefore 8. As a point on the graph, this is ( 0, 8 )

A 9-sided shape is called a nonagon.

Therefore the answer is nonagon.

A nonagon is a polygon with nine sides and nine angles. A nonagon can be regular or irregular, depending on the lengths of its sides and angles. A regular nonagon has equal sides and angles, while an irregular nonagon has sides and angles of different lengths.

Nonagons are two-dimensional shapes, and they can be described by their number of sides, angles, and vertices. They are considered a type of polygon, which is a closed geometric figure that is made up of straight lines. In addition to nonagons, there are other types of polygons such as triangles, quadrilaterals, pentagons, hexagons, heptagons, and so on.

Im Sorry if its wrong

Answer:  Part A:

To represent the cost per night x and cost per meal y in a system of equations, we can use the information provided in the question:

First Special:

3x + 4y = 233

Second Special:

3x + 3y = 226.50

Where x is the cost per night and y is the cost per meal.

Part B:

To find the cost per night and the cost per meal, we can use the information provided in the question and system of equations.

We can solve this system of equations using several methods: substitution or elimination method.

One common method to find the solution is by substitution method, where we find the value of x in terms of y from one of the equations and then substitute it into the other equation to solve for y.

x = (233 - 4y)/3

then substitute it into the other equation:

3(233 - 4y) + 3y = 226.50

now solve for y:

699 - 12y + 3y = 226.50

-9y = -472.50

y = 52.50

and we can substitute it back into the first equation:

3x + 4(52.50) = 233

3x = 80.50

x = 26.83

So the cost per night is $26.83 and the cost per meal is $52.50

Step-by-step explanation:

The system represents the cost of the beginner class will be $18 and the advanced class will be $24.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Both basic and expert magic lessons are available at Wacky Wizards. More than half as much is spent on the introductory class as there is on the advanced level. They made $390 last week by instructing 7 basic lessons and 11 advanced classes.

Let 'x' be the cost of beginner classes and 'y' be the cost of advanced classes. Then the equations are given as,

x = y / 2 + 6

y = 2x - 12             ...1

7x + 11y = 390      ...2

From equations 1 and 2, then we have

7x + 11(2x - 12) = 390

7x + 22x - 132 = 390

29x = 522

x = 18

Then the value of the variable 'y' is calculated as,

y = 2(18) - 12

y = 36 - 12

y = 24

The system represents the cost of the beginner class will be $18 and the advanced class will be $24.

The quantities which are proportional to 12/4 are 36/12 and 3/1 .

What is proportional ?

If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.

In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.

The relationship between two quantities is constant for all values when they are proportional, which indicates that as one quantity rises, the other rises as well. An illustration would be the ratio of a circle's circumference to its diameter, which is equal to pi.

12/4 ⇒ 3/1

          = 24/9

          = 8/3

The quantity 12/4 is not proportional to 48/18

        = 18/6

        = 3/1

The quantity 12/4 is proportional to 36/12

       = 7/3

The quantity 12/4 is not proportional to 35/15

       = 12/8

So it took Xander approximately 9.96 minutes to run 1 mile during the race.

To convert the distance of the race from kilometers to miles, you can use the conversion factor 1 kilometer = 0.621 miles.

To find the time it took Xander to run 1 mile, you can divide the total time it took him to run the entire race by the number of miles he ran.

First, convert the distance of the race from 5 kilometers to miles:

5 kilometers * 0.621 miles/kilometer = 3.105 miles

Then, divide the total time it took Xander to run the race by the number of miles he ran:

31 minutes / 3.105 miles = 9.96 minutes/mile

So it took Xander approximately 9.96 minutes to run 1 mile during the race.

Matching a logarithmic function with its graph can be done by understanding the key characteristics of logarithmic functions and how they are represented on a graph.

A logarithmic function is of the form y = log base b (x), where b is the base of the logarithm (usually 10 or e).

The graph of a logarithmic function is a reflection of the exponential function of the same base b, across the line y=x.

Here are some key characteristics of logarithmic functions and their corresponding graphs:

1) Asymptote: The graph of a logarithmic function has a vertical asymptote at x=0, since the logarithm of a non-positive number is undefined.

2) Domain: The domain of a logarithmic function is x>0, since the logarithm of a negative number is undefined.

3)Range: The range of a logarithmic function is all real numbers

4) Increasing or decreasing: A logarithmic function is increasing over its domain

5) Shape: The graph of a logarithmic function is concave down.

6) x-intercept: The x-intercept of the graph is (1,0), since the logarithm of 1 is always 0.

By keeping these characteristics in mind, you can match a logarithmic function with its graph by observing the shape, asymptote, domain and range of the graph.
