Answer:

area of a trapezoidal base  of each prism with heights  6 and 8 units are 4 square units and 3 square units respectively

Step-by-step explanation:

Let us first be aware of formula of volume for any regular geometrical figure.

Fundamental formula for  volume for any regular geometrical figure is.

volume = area of cross section of object*  height of object (A)

In the problem stated area of cross section of object will be  area of a trapezoidal base.

Given in the question is

Volume of both the trapezoidal prisms = 24 cubic units

*************************************************************************************

For prism with height 6 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 6 * area of a trapezoidal base

=> area of a trapezoidal base = 24/6 = 4 square units

*************************************************************************************

For prism with height 8 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 8 * area of a trapezoidal base

=> area of a trapezoidal base = 24/8 = 3 square units

*************************************************************************************

Therefore area of a trapezoidal base  of each prism with heights  6 and 8 units are 4 square units and 3 square units respectively.

Answer:

42.5 units²

Step-by-step explanation:

Total height of rectangle = 3.5 + 2 = 5.5 units

Total area (without triangles removed) = 5.5 x 9.0 = 49.5 units²

The measurements and area of the triangles removed are equal to those on the diagram, so calculate the area of the triangles and subtract them from the total area.

Left: (0.5)(2)(2) = 2 units²

Right: (0.5)(5)(2) = 5 units²

Area: 49.5 - 2 - 5 = 42.5 units²

Answer:

1.50n≤84

Step-by-step explanation:

The statement indicates that Samantha knows that she has made at most $84 in sales and this means that that is the higher amount she thinks she can have. So, the total amount could be less than that or equal to that. Also, the total amount she has would be the result of multiplying the price per ticket for the number of tickets sold. Moreover, this amount would be less than or equal to 84 and the symbol that represents less than or equal to is ≤. According to this, the inequality that would model the information is: 1.50n≤84.

Answer:

Change in net operating income = $4,950

Step-by-step explanation:

Missing Detail;

Contribution margin = $105 per unit

Current selling unit = 5,300

Increase in monthly sale = 190 unit

Advertisement cost = $15,000

Find:

Change in net operating income

Computation:

Change in net operating income = [Contribution margin x Increase in monthly sale] - Advertisement cost

Change in net operating income = [105 x 190] - 15,000

Change in net operating income = [19,950] - 15,000

Change in net operating income = $4,950

Answer:

[tex]f + e + d = 360^o[/tex]

Step-by-step explanation:

The question is incomplete, as what is required is not stated and the triangle is not given.

So, I will solve generally.

The proof is as follows (see attachment for triangle)

From the attachment, we have:

[tex]a + f = 180[/tex]

[tex]b + e = 180[/tex]

[tex]c + d = 180[/tex]

Make f, e and d the subject

[tex]f = 180 - a[/tex]

[tex]e = 180 - b[/tex]

[tex]d = 180 - c[/tex]

Add up the equations

[tex]f + e + d = 180 -a + 180 - b + 180- c[/tex]

Collect like terms

[tex]f + e + d = 180 + 180+ 180-a- b - c[/tex]

[tex]f + e + d = 540-a- b - c[/tex]

We have:

[tex]f + e + d = 540-(a+ b + c)[/tex]

[tex]a + b + c \to 180[/tex] --- angles in a triangle

So, we have:

[tex]f + e + d = 540-180[/tex]

[tex]f + e + d = 360^o[/tex] --- proved

Answer:

  A)  3 1/4

Step-by-step explanation:

Your calculator can help with this.

__

  3/4 + ((1/3)/(1/6)) -(-1/2)

  = 3/4 + ((2/6)/(1/6)) + 2/4

  = 5/4 + 2/1

  = 3 1/4

Q) 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2) = ?

→ 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2)

→ 3/4 + {(1/3) × (6/1)} - ( - 1/2)

→ 3/4 + 6/3 - ( - 1/2)

→ {(3/4) + (6/3)} + 1/2

→ 11/4 + 1/2

→ (11 + 2)/4 = 13/4

→ 3 1/4

Hence, option (A) is the answer.

The expected value for the number of siblings of a randomly chosen student is 1.11.

"In a probability distribution, the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value".

For the given situation,

The table shows the probability distribution of siblings of students in a high school with 1500 students.

For number of siblings = 0, Probability = 0.18.

For number of siblings = 1, Probability = 0.65.

For number of siblings = 2, Probability = 0.09.

For number of siblings = 3, Probability = 0.05.

For number of siblings = 4, Probability = 0.02.

For number of siblings = 5, Probability = 0.01.

The formula for expected value mean, E(x) = ΣxP(x)

[tex]E(x)=(0)(0.18)+(1)(0.65)+(2)(0.09)+(3)(0.05)+(4)(0.02)+(5)(0.01)[/tex]

⇒ [tex]E(x)=1.11[/tex]

Hence we can conclude that the expected value for the number of siblings of a randomly chosen student is 1.11.

Answer:

  21.6 years

Step-by-step explanation:

The first statement tells you the account balance can be modeled by ...

  A = 440(2)^(t/8) . . . . . where t is in years

We want to find t when A = 2860

  2860 = 440(2^(t/8))

  6.5 = 2^(t/8) . . . . . . . . . . divide by 440

  log(6.5) = (t/8)log(2) . . . . take logarithms

  t = 8·log(6.5)/log(2) ≈ 21.604 . . . . . . divide by the coefficient of t; evaluate

It would take about 21.6 years for the value to reach $2,860.

Given:

The vertices of the parallelogram RSTU are R(-4,4), S(2,6), T(6,2) and U(0,0).

To find:

The perimeter of parallelogram RSTU, rounded to the nearest whole number.

Solution:

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the distance formula, we get

[tex]RS=\sqrt{(2-(-4))^2+(6-4)^2}[/tex]

[tex]RS=\sqrt{(6)^2+(2)^2}[/tex]

[tex]RS=\sqrt{36+4}[/tex]

[tex]RS=\sqrt{40}[/tex]

[tex]RS=6.32[/tex]

Similarly,

[tex]ST=\sqrt{\left(6-2\right)^2+\left(2-6\right)^2}[/tex]

[tex]ST\approx 5.66[/tex]

[tex]TU=\sqrt{\left(0-6\right)^2+\left(0-2\right)^2}[/tex]

[tex]TU\approx 6.32[/tex]

[tex]RU=\sqrt{\left(0-\left(-4\right)\right)^2+\left(0-4\right)^2}[/tex]

[tex]RU\approx 5.66[/tex]

Now, the perimeter of the parabola is:

[tex]P=RS+ST+TU+RU[/tex]

[tex]P=6.32+5.66+6.32+5.66[/tex]

[tex]P=23.96[/tex]

[tex]P\approx 24[/tex]

The perimeter of the parallelogram RSTU is 24 units.

Therefore, the correct option is C.

Note: Unit of perimeter cannot be in square.

Answer:

  C.  (-1, 2) and (4, 7)

Step-by-step explanation:

It may be simplest just to try the answer choices.

We notice that y = x+3 is not satisfied by the points in choices A or D, so those can be eliminated.

__

The second equation can be written in vertex form as ...

  y = (x -1)^2 -2

This equation is not satisfied by the points of choice B.

  Using (-1, 4) (from choice B), we get 4 = (-1-1)^2 -2 = 4-2 = 2 . . . FALSE.

However it is a good match for the points of choice C.

  Using (-1, 2) (from choice C), we get 2 = (-1-1)^2 -2 = 4 -2 = 2 . . . True

The appropriate choice is ...

  (-1, 2) and (4, 7)

The transformation of a function may involve any change. The correct option is D.

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:

Horizontal shift (also called phase shift):

Vertical shift:

Stretching:

The given function f(x)=x² is transformed to h(x)=(1/8)x^2-13, therefore, the graph or f(x) is horizontally stretched by a factor of 8 and shifted 13 units to the right.

Hence, the correct option is D.
