The width of the box is 12 inches

The formula for calculating the volume of a rectangular box is expressed as:

where:

• l is the ,length ,of the box

• w is the ,width, of the box

• h is the ,height ,of the box

Given the following parameters

• length = 18 inches

• heigh = 9 inches

• volume = 1,944 cubic inches

Substitute the given parameters into the formula to calculate the width of the box as shown:

Divide both sides by 162 to have:

Hence the width of the box is 12 inches

The correct answer is Option A ( III Only). I . -16 sum cannot be negative, II. Not a G.P, III. Sum = 1/4, and IV. Not a G.P.

Given geometric series,

I. 4 +5 +25 /4 ….

The common ratio(r) is (5/1)/(4/1) = 5/4.

S∞ = a / ( 1 - r)

     = 4 / ( 1 - 5/4)

     = 4 / -1/4

S∞ = -16.

Since sum cannot be negative.

II . -7 + 7/3 - 7/9+ ....

  Here common ratio = -7 / (7/3) = -1/3

   but - 7/9 / 7 /3 = 7/9

Here there is no common ratio so this not a G.P.

iii. 1/2 -1 + 2.....

     Common ratio = -1 / (1/2) =  -2

     S∞ =  a / ( 1 - r)

           = 1/2 / (1 -(-2))

     S∞  = 1/4.

iv  4 - 8/5 +16/5.....

   Here there is no common ratio.

   So this is not a G.P.

Because x is continuous, we should use interval notation, the domain is:

D: [1, ∞)

For a function y = f(x), we define the domain as the set of possible inputs of the function (possible values of x).

To identify the domain, we need to look at the horizontal axis. The minimum value is the one we can see in the left side, and the maximum is the one we could see on the right side.

There we can see that the domain starts at x = 1 and extends to the left, so the notation we can use for the domain is:

D: x ≥ 1

We know that the value x =1 belongs because there is a closed dot there.

The correct option is A, because the domain is continuous (as we can see in the graph), we should use interval notation. In this case the domain can be written as:

D: [1, ∞)

2 (x - 1

The percent error of the house of the pizza would be 2.

The difference between the estimated and actual values in comparison to the actual value is expressed as a percentage. In other words, the relative error multiplied by 100 equals the percent error.

Percent errors indicate the magnitude of our errors when measuring something in an analysis process. Lower percentage errors indicate that we are getting close to the accepted or original value.

Suppose the actual value and the estimated values after the measurement are obtained. Then we have:

Error = Actual value - Estimated value

To determine the percent error, we will measure how much percent of the actual value, the error is, in the estimated value.

We have been given that House of Pizza says that their pizzas are 14 inches wide, but when measured, the pizza was 12 inches.

WE know that Error = Actual value - Estimated value

Then Error = 14 - 12 = 2

Therefore, the percent error would be 2.

ANSWER

EXPLANATION

First, let us make a sketch of the problem:

To find the time it will take the airplane to be in the clouds, we first have to find the distance flown by the airplane in attaining that height, x.

To do this, apply trigonometric ratios SOHCAHTOA for right triangles:

Solve for x:

Now, that we have the distance, we can solve for the time by applying the relationship between speed and distance:

Substitute the given values into the formula above and solve for time:

That is the number of seconds that it will take.

Since 2000 pounds = 907 kilograms, use the conversion factor:

Therefore,

The slope of the line = -1

Expanding 7(x - y) in the above expression gives

adding the like terms (2x+ 7x) and (-5y-7y) gives

The last expression is the simplest form we can convert our expression into.

let f(x) = y

To find the inverse of f(x), we would interchange x and y:

Then we would make the subject of formula:

In interval notation:

In this case the aswer is very simple. .

The congruent parts are the equal parts in the 2 triangles.

The following diagram will help us solve the problem

(a) From the diagram, the height of the parallelogram is given as TR, and it is 40 mm

Now we can use the area which is given to us as 3,600 square-mm to find the base of the parallelogram, which is PQ

So,

Step-by-step explanation:

Answer: Total perimeter = 9, 962.01 feet

The figure is a composite structure

It contains a rectangle and triangle

The perimeter of a rectangle is given as

Perimeter = 2( length + width)

length of the rectangle = 1500ft

Width of the rectangle = 1390 ft

Perimeter = 2( 1500 + 1390)

Perimeter = 2(2890)

Perimeter = 5780 ft

To calculate the perimeter of a triangle

The total perimeter of the field = Perimeter of the rectangle + perimeter of the right triangle

Total perimeter = 5780 + 4182.01

Total perimeter = 9, 962.01 feet

The given decimal can be written as a quotient of 513/1000.

What is quotient?

In maths, the result of dividing a number by any divisor is known as the quotient. It refers to how many times the dividend contains the divisor. The statement of division, which identifies the dividend, quotient, and divisor, is shown in the accompanying figure. The dividend 12 contains the divisor 2 six times. The quotient is always less than the dividend, whether it is larger or smaller than the divisor.

we can write the decimal given 0.513 as a answer of of 513 divided by 1000.

Hello!

First, let's rewrite the function:

Now, let's find each coefficient of it:

• a = -2

• b = 108

• c = 75

As we have a < 0, the concavity of the parabola will face downwards.

So, it will have a maximum point.

To find this maximum point, we must obtain the coordinates of the vertex, using the formulas below:

So, the coordinate x = 27.

The coordinate y = 1533.

Answer:

The maximum profit will be 1533 (value of y) when x = 27.
