Answer:

  582 cm²

Step-by-step explanation:

You want the area of the figure represented by the given net.

The surface area of the cuboid is the sum of the areas of the rectangles shown in its net. Working top down and left to right, that sum is ...

  A = ∑LW

  A = (13)(10) +(10)(7) +(13)(7) +(10)(7) +(13)(10) +(13)(7)

  A = 2(13(10) +10(7) +13(7)) = 2(130 +70 +91) = 2·291 = 582

The surface area of the right rectangular prism is 582 square centimeters.

__

Additional comment

The formula can be shortened to ...

  A = 2(LW +H(L +W))

  A = 2(13·10 +7(13 +10)) = 2(130 +161) = 582

Answer:

Ratio of lengths is 1:3

Ratio of areas is 1:9

Step-by-step explanation:

Firstly, we need the units to be same

Mathematically, 1 yard = 3 feet

A length of 1/4 yards = 1/4 * 3 = 3/4 feet

A width of 1/4 yards = 1/4 * 3 = 3/4 feet

The ratio of the length of the tile to the length of the board

that would be;

1/4 : 3/4 = 1: 3

Let’s now work with area

Mathematically, area in both cases is length * width

For the board, we have that;

3/4 * 3/4 = 9/16 square feet

For the tile, we have that;

1/4 * 1/4 = 1/16 square feet

so the ratio of the tile area to the board area will be;

1/16 : 9/16 = 1: 9

To determine the number of tons of metal per year needed for Machine A to be favored over Machine B, we compare their costs. Machine A costs $323,000 with an annual operating cost of $2.40/ton, while Machine B costs $178,000 with an annual operating cost of $8.00/ton. The machines have useful lives of 10 years and 6 years, respectively, and the minimum attractive rate of return (MARR) is 18% per year.

By calculating the equivalent annual costs (EAC) for each machine using the given formula and comparing them, we can determine the point at which Machine A becomes more favorable. However, specific values for the discounting factors and the tons per year needed are missing, making it impossible to provide an exact answer.

Answer:

1/10 in first row

1/20 in second row

1/5 in third row

Step-by-step explanation:

it is simple, take first row, and look what is required to get 1,

here 5*2 is 10, so to get 1 we need to divide with 10

in second row, 20*1 is 20, so we need to divide with 20

and in third row 10* ½ is 5, so we need to divide with 5

Answer:

To answer this, we have to do the equation below:

\(1,380/80\)

When we do this, we come up with the answer of 17.25

Now we know that we get paid $17.25 an hour.

Now, we must do the equation below:

\(100 X 17.25\)

When we multiply, we get the answer of 1,725

So, we get paid $1,725 if we work for 100 hours.

Given:

The given terms are

\(4p^3mn^2\) and \(2pm^2n^3\)

To find:

The common factors of given terms.

Solution:

We have,

\(4p^3mn^2\) and \(2pm^2n^3\)

The factor forms are

\(4p^3mn^2=2\times 2\times p\times p\times p\times m\times n\times n\)

\(2pm^2n^3=2\times p\times m\times m\times n\times n\times n\)

The common factors are 2, p, m, n, n. So,

Common factors = \(2\times p\times m\times n\times n\)

                            = \(2pmn^2\)

Therefore, the common factor of given terms is \(2pmn^2\).

Answer:

h = 3

Step-by-step explanation:

y-6 = 4/7 (x-(-4)

y - 6 = 4/7 (x+4)

y - 6 = 4/7 x + 16/7

y = 4/7 x + 16/7 + 6

y = 4/7 x + (16+42)/7

y = 4/7 x + 58/7

10 = 4/7 x + 58/7

4/7 x = 10 - 58/7

4/7 x = (70-58)/7

4/7 x = 12/7

7/4 * 4/7 x = 12/7 * 7/4

x = 3

Answer:

-8 (or) 5 and 5 (or) -8

Step-by-step explanation:

Let one of the numbers = x

Let other number = y

As the sum of two numbers = -3

x + y = -3

x = -3-y

As the the result of multiplication = -40

xy = -40

(-3-y)*y = -40

-3y-y² = -40

-y²-3y+40 = 0

-(y²+3y-40) = 0

-(y+8)(y-5) = 0

(-y-8)(y-5) = 0

-y-8 = 0 (or) y-5 = 0

-y = 8 (or) y = 5

y = -8 (or) y = 5

when y = -8

x = -3-y

x = -3-(-8)

x = -3+8

x = 5

when y = 5

x = -3-y

x = -3-5

x = -8

Answer:

Choice D.

Step-by-step explanation:

5.2

Since N/2 leaves a remainder, N must be odd and ends with 1, 3, 5, 7, or 9.

N/5 also leaves a remainder, so N is not divisible by 5, so it does not end in 5.

The only correct choice is then 9, since

1 = 0•5 + 1 and 1 = 0•2 + 1

3 = 0•5 + 3 and 3 = 1•2 + 1

7 = 1•5 + 2 and 7 = 3•2 + 1

9 = 1•5 + 4 and 9 = 4•2 + 1

Alternatively, the given information is equivalent to saying

\(N\equiv 4\pmod5\\\\N\equiv1\pmod2\)

Then you can use the Chinese remainder theorem to find N.

Answer: The common ratio r is s2/5 = sqrt(s2), the fifth term is ar^4 = s8/5 = 25s4/5, and the nth term is ar^(n-1) = s2/5 * sqrt(s2)^(n-1).

Step-by-step explanation:

The general form of a geometric sequence is given by:

a, ar, ar², ar², ...

where a is the first term and r is the common ratio.

In this case, we have:

a = 1

ar = s2/5

ar² = s4/5

ar³ = s6/5

We can use the second and third equations to solve for r:

ar / a = (s2/5) / 1

r = s2/5

ar² / ar = (s4/5) / (s2/5)

r = sqrt(s4/5 / s2/5) = sqrt(s4/s2) = sqrt(s2)

Since we have two expressions for r, we can equate them and solve for s:

s2/5 = sqrt(s2)

s2 = (s2/5)²

s2 = s4/25

25s2 = s4

s4/5 = 25s2/5

Therefore, the common ratio r is s2/5 = sqrt(s2), the fifth term is ar^4 = s8/5 = 25s4/5, and the nth term is ar^(n-1) = s2/5 * sqrt(s2)^(n-1).

B. The sequence diverges.

Explanation:

We can use the limit comparison test to show that the given sequence diverges.

First, we note that the term "-1" does not affect the behavior of the sequence as n approaches infinity.

Next, we can simplify the term "tan(9n)/(9n+5)" by dividing both the numerator and denominator by 9n. This gives us:

tan(9n)/(9n+5) = (tan(9n)/(9n))/((9n+5)/(9n))

Now, we know that as n approaches infinity, (tan(9n)/(9n)) approaches 1 (this can be shown using L'Hopital's rule).

Therefore, we can compare the given sequence to the sequence:

(1/(9n)) * (9n/(9n+5))

As n approaches infinity, the second factor in this sequence approaches 1, while the first factor approaches 0.

By the limit comparison test, since the limit of this new sequence is 0, and the given sequence is always nonnegative, the given sequence must also have a limit of 0.

Therefore, the sequence diverges.
The given sequence is -1 * tan((9n)/(9n+5)). To find the limit of the sequence as n approaches infinity, we can analyze the argument of the tangent function.

As n approaches infinity, the term (9n)/(9n+5) approaches 1 (since the coefficients of the highest powers of n are equal). Therefore, the argument of the tan function approaches 1, which is not a multiple of π (pi).

Now, considering the limit of -1 * tan(1), as the tangent function is continuous and well-defined at 1, we can directly find the limit. The limit of the sequence is -1 * tan(1).

So, the correct choice is:

A. The limit of the sequence is -1 * tan(1). (Type an exact answer.

So, the statement "In a dataset that is normally distributed, the mean is always equal to the standard deviation" is false.

In a dataset that is normally distributed, the mean and the standard deviation are two different measures that describe different aspects of the data.

The mean is the arithmetic average of the dataset and represents the center of the distribution. It is calculated by adding up all the values in the dataset and dividing by the number of values.

The standard deviation, on the other hand, measures the spread or variability of the data around the mean.

It is calculated by taking the square root of the average of the squared differences between each value and the mean.

While the mean and the standard deviation can take on the same value in some cases, such as in a normal distribution with a standard deviation of 1, this is not always the case.

Therefore, in a normally distributed dataset, the mean and the standard deviation are two separate measures of the data.

So statement is false. In fact, it is more common for the mean and standard deviation to be different values in a normally distributed dataset.

Answer:

  (b)  5994 cm²

Step-by-step explanation:

You want to know the area of a triangle with base 6ac² and height 3 cm more, given that a=2 and c=3.

The base of the triangle is ...

  base = 6ac² = 6(2)(3²) = 108 . . . . cm

The height of the triangle is 3 cm more, so is ...

  height = base + 3 = 108 cm +3 cm = 111 cm

The area is half the product of base and height:

  A = 1/2(base)(height)

  A = 1/2(108 cm)(111 cm) = 5994 cm²

The area of the triangle is 5994 cm², matching choice B.
