The representation of the volume of the prism in greatest to least volume is third > first > second.

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

As per the given cuboid prism.

The volume of the cuboid = length × height × width.

First cube = 1/4 x 3 x 6 x 2 = 9 units³

Second cube = 1/2 x 2 x 3 x 1 = 3 units³

Third cube = 1/8 x 8 x 11 x 4 = 44 units³

So, 44 > 9 > 3.

Hence "The representation of the volume of the prism in greatest to least volume is third > first > second".

Answer:

Step-by-step explanation:

times the number by two

Answer:

x = -7

Step-by-step explanation:

First step is to expand the left side of the equation. To do this, multiple 4 by each term on the inside of the paratheses.

4 * 2x = 8x

4 * 14  = 56

This gives you the equation:

8x + 56 = 0

Now, get the x term on one side by itself by subtracting 56 on both sides:

8x = -56

And solve for x by dividing both sides by 8:

x = -7

Answer:

One gets  Rs 24 and the other Rs 96.

Step-by-step explanation:

Number of parts = 1 + 4 = 5

So one student gets 1/5 of 120 and the other gets 4/5 of 120

120 * 1/5 = 24

120 *4/5 =  4*24 = 96.

Answer:

One would get 96 and another would get 24

Step-by-step explanation:

So first lets create an equation from the words where 4x is what one students has and x is what another has :

120 = 4x + x

Lets solve this now!

120 = 5x (divide by 5 on both sides)

24 = x (1st Student)

(Multiply by 4 on both side to get the second student)

96 =4x (2nd Student)

If the company wants to keep its production costs under $781.12 a reasonable domain for the constraint x is  -12.9892≤ x ≤ 1012.99.

A constraint is a condition of an optimization problem that should be satisfied the condition.

Let  x is an element of a subset of the integers,

C(x) is the production cost, in thousands of dollars

[tex]C(x) = 50 +3.8x -0.0038x^2,[/tex]

This is a vertical parabola open downward (the leading coefficient is negative)

we know that

For the interval [-12.9892, 1012.99] = -12.9892≤ x ≤ 1012.99

The value of C(x) = C(x) < 781.12

That means the production cost is under $781.12

Remember that the variable x (number of tires) cannot be a negative number.

If the company wants to keep its production costs under $175,000 a reasonable domain for the constraint x is -12.9892≤ x ≤ 1012.99

Answer:

Area = 21.7 cm² (nearest tenth)

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle.  The measures of its sides have a special relationship in that they are in proportion:

shortest leg : longest leg : hypotenuse =  1 : √3 : 2

So we can also write the ratio as  [tex]x : x\sqrt{3} : 2x[/tex]  where [tex]x[/tex] is the shortest side.

From inspection of the diagram, the shortest side is 5 cm

⇒ BC (height) = 5 × √3 = 5√3 cm

Now we have the height, we can calculate the area.

Area of a triangle = 1/2 x base x height

                             = 1/2 x 5 x 5√3

                             = 21.7 cm² (nearest tenth)

Answer:

SA = 224 ft^2

Step-by-step explanation:

B - base

H - height

SA - surface area

B = 8

H = 10

SA = (B×B) + 4((1/2)×(B×H))

SA = (8×8) + 4((1/2)×(8×10))

SA = 224 ft^2

Answer:

13.727

Step-by-step explanation:

Explanation

Given: You choose the four packages of modeling clay and the set of equipment indicated on the right for a creative project.

To find: the total cost if there is a 6% sales tax.

We will calculate the total cost of each item and then add.

Tip

The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.

The formula is: Total cost = (Average fixed cost x average variable cost) x Number of units produced.

Step 1

The cost of 4 packets of clay is given by:

4 x $2.79



Step 2

We will calculate the product:

4 x 2.79 = 11.16

Step 3

We will add the cost of 4 packets of clay and a pack of tools to get the total cost without tax:

$(11.16 + 1.79)



Step 4

We will add the numbers:

11.16 + 1.79 = 12.95

Step 5

The 6% tax on the total price is given by:

6% x $12.95

Step 6

We will calculate the sales tax:

6/100 x 12.95 = 0.777



Step 7

We will add the total cost without tax and tax amount to get the total amount paid:

$(12.95 + 0.777)



Step 8

We will add the amounts:

12.95 + 0.777 = 13.727

Step 9

x=2 and y=(-2)

hope it helps...

Answer:

y = ( -2 )

x = 2

Step-by-step explanation:

4x + y = 6 ⇒ ( 1 )

x - 2y = 6  ⇒ ( 2 )

x = 6 + 2y ⇒ ( 3 )

First, let us find the value of y.

For that, we can replace x with ( 6 + 2y ).

Let us use equation 1 for that.

4x + y = 6

4 ( 6 + 2y ) + y = 6

24 + 8y + y = 6

24 + 9y = 6

9y = 6 - 24

9y = -18

Divide both sides by 9.

y = -2

Now let us find the value of x by replacing y with -2.

For that let us take equation 3.

x = 6 + 2y

x = 6 + 2 × -2

x = 6 - 4

x = 2

Answer:

-26

Step-by-step explanation:

4-30=-26

The mean, median and range of the given data are respectively; 49, 48 and 3.

Formula for mean is;

Mean = Total sum/sample size

Total sum = 48 + 51 + 48 + 48 + 50

Total sum = 245

Sample size = 5

Mean = 245/5

Mean = 49

To get the median, we arrange in ascending order and pick the mid term.

48, 48, 48, 50, 51

Median is mid term which is 48.

Range is difference between highest and lowest term.

Range = 51 - 48

Range = 3

Answer: x<17.5

Step-by-step explanation:

Subtract  from both sides: x+2.5-2.5<20-2.5

Simplify the arithmetic: x<20-2.5

Simplify the arithmetic: x<17.5

Hope it helps!

Answer: B) 12.5

Step-by-step explanation:

Start by isolating x by subtracting 2.5 from both sides

[tex]x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5[/tex]

This reads as "x is less than 17.5"

D can be eliminated because it is greater than 17.5

C can be eliminated because 17.5 can't be less than itself

So the answer must be B since it is less than 17.5 and greater than A

Answer:

4(4x−9)

Step-by-step explanation:

We let x = pounds of alloy that is 15% tin

The problem is modeled by the equation:

0.11(30) = 0.15x + 0.09(30-x)

The equation means that the amount of tin does not change. Also, the amount of alloy (total weight - weight of 15% alloy) is (30-x).

Solving for x:

3.3 = 0.15x +2.7 - 0.09x

.06x = 0.6

x = 10 lbs

30-10 = 20 lbs

10 lbs. of the 15% alloy and 20 lbs. of the 9% alloy
