The area of the base of this rectangular prism is 6 in.². The height is 12 inches. What is the volume of the rectangular prism?

Answer:

1,395 sq feet

Step-by-step explanation:

lets start with the area of the green cube b×h. 15×15=225. 225×5= 1125. I got five because there are 5 visible faces on the cube. to find the area of a triangle you use the formula 1/2 bh 9×15= 135 multiply that by 2 instead of one half because you have four triangular faces. add your areas together and you get 1395

Answer: 1465

Step-by-step explanation:

225 base

225 for each wall  (x4)

540 area for the top

Tristan's fish tank is 1/2 yard long,  1/6 yard wide, and  1/3 yard high. (Note that the fish tank is in the shape of a rectangular prism and not a cube.) One way of finding the volume of the tank is by dividing the tank into cubic blocks. What should the side lengths of each cubic block used to find the volume be?

Answer:

the side lengths are 3 sides, 1 side and 2 sides  of each cubic block.

Step-by-step explanation:

The volume of the rectangular prism is:

[tex](1/2 \ yard) * (1/6 \ yard) * (1/3 \ yard) = 1/36 \ yard^3[/tex]

However: let's find their lowest common multiples to determine their side length.

Multiples of 2:   2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, ...

Multiples of 6:   6, 12, 18, 24, 30, ...

Multiples of 3:   3, 6, 9, 12, 15, 18, 21, 24, 27, 30,  ...

The lowest common multiple for 2 , 6 and 3 is 6 .

Then in terms of the side length of each cubic block; we have :

1/2 × 6 = 3

1/6 × 6 = 1

1/3 × 6 = 2

So the side lengths are 3 sides, 1 side and 2 sides  of each cubic block

Answer:

He walked 2.75 miles in one hour         (distance in miles)

He walked 2 miles 3960 feet  in one hour           (distance in feet and miles)

He walked 14520 feet  in one hour                  (distance in feet)

Step-by-step explanation:

Using proportion to solve;

Let x be the distance(in mile) walked in one hour

11 miles = 4 hours

  x         = 1 hour

cross-multiply

4×x = 11

4x = 11

Divide both-side of the equation by 4

4x/4 = 11/4

At the right-hand side of the equation, 4 will cancel-out 4 leaving us with just x

x =2.75 miles

He walked 2.75 miles in one hour

Converting it to feet and miles

1 mile = 5280 feet

0.75 mile  =  y

y = 0.75×5280

   =3960 feet

he walked 2 miles 3960 feet  in one hour

To convert  it to feet

1 mile = 5280 feet

2.75 miles  = x

x = 2.75×5280

x = 14520 feet

he walked 14520 feet  in one hour

Answer:

It is 5 km/hour

Step-by-step explanation:

Let w represents the speed of the water

The speed can be found by following:

→ distance = speed x time → speed = distance / time (1)

If the boat goes downstream the total speed of the boat is the speed of the boat in still water + the speed of the water. Substitute the values into equation 1:

→ (the speed of the boat in still water + the speed of the water) = 120 / 4

Since the speed of the boat in still water is 25

→ 25 + w = 120 / 4

→ w + 25 = 30

→ w = 5

Answer:

  3171 square meters

Step-by-step explanation:

You want the surface area of a 35 m square pyramid that has a volume of 8820 cubic meters.

The volume is given by ...

  V = 1/3s²h

so the height of the pyramid is ...

  h = 3V/s² = 3(8820)/35² = 21.6 . . . . meters

The slant height of one triangular face of the pyramid is found from the Pythagorean theorem:

  c² = a² +b²

  c² = 21.6² + 17.5² = 772.81

  c = √771.81 ≈ 27.799 . . . . . . meters

The surface area of the pyramid is the sum of the area of the square base and the lateral area of the four triangular faces.

  SA = s² + 4(1/2)(sc) = s(s +2c)

  SA = 35(35 +2·27.8) = 3171 . . . . square meters

The surface area of the Louvre Pyramid is about 3171 square meters.

Answer:Dudley is 50 feet from the flagpole.

Step-by-step explanation:

The situation is represented in the attached diagram. FL represents the flagpole.

A represents the position of Asher.

B represents the position of Baxter.

C represents the position of Cranby.

D represents the position of Dudley.

Looking at the diagram, Dudley is at the same level with Asher but eastwards of the flagpole. The distance of Dudley from the flagpole would be

100 - 50 = 50 feet

Final answer:

Dudley is 100 feet east from the flagpole after the friends have each moved from their starting positions.

Explanation:

The question describes four friends at different locations in relation to a flagpole, and we are asked to determine how far Dudley is from the flagpole after following the described steps by the friends. To solve this, we can visualize or draw a diagram to represent the positions of friends and use the Pythagorean theorem to find the distance Dudley is from the flagpole.

First, let's determine the position of Cranby.

Since Baxter moved 50 feet north from Asher's position and then Cranby moved 100 feet east from Baxter's position, we can see that Cranby is 100 feet east and 50 feet north of the flagpole.

Dudley, standing 50 feet south of Cranby, would thus be at the same north-south position as the flagpole but still 100 feet to the east.

Therefore, Dudley is 100 feet east of the flagpole.

Answer: 3

Step-by-step explanation:

Evaluate is a fancy word for putting the value assigned into the equation and see what result you get.

[tex]-2x^2-4x+3\\x=-2[/tex]

[tex]-2(-2)^2-4(-2)+3\\-2(4)+8+3\\-8+8+3\\3[/tex]

To evaluate the expression −2x²−4x+3 for x=−2, substitute x with -2 and perform the operations: square x, multiply by -2, multiply -4 by x, and add the results to get the final answer of 3.

To evaluate the expression
−2x²−4x+3 when x=−2, we need to substitute x with −2 and then follow the order of operations, which is to perform exponentiation before multiplication and addition.

Thus, −2x²−4x+3 evaluates to 3 when x is −2.

Answer:

81 meters.

Step-by-step explanation:

The height (in meters), h(x) of a hovercraft x seconds after takeoff, is modeled by:

[tex]h(x)=-3(x-3)^2+108[/tex]

We are to determine its height at the time of takeoff.

Now, at the time of takeoff, x=0.

We substitute x=0 to solve for h.

[tex]h(0)=-3(0-3)^2+108\\=-3(-3)^2+108\\=-3(9)+108\\=-27+108\\=81$ meters[/tex]

The height of the hovercraft at takeoff is 81 meters.

The required set of ordered pairs are (0, 1), (1, 3), (2, 9), (3, 27). The correct option is (D).

An exponential function can be represented as y = aˣ. When x = 0, y = a⁰ = 1. The range of an exponential function is from zero to infinity for a > 0.

It is clear from the given options that, only options (B) and (D) satisfies the general expression y = aˣ at x = 0.

Now, both these options can be examined one by one as follows,

Option (B),

The ordered pairs are given as (0, 1), (1, 2), (2, 5), (3, 10).

Substitute the values in the general expression y = aˣ, first two pair are satisfied for a = 2 but the remaining two are not.

Option (D),

The ordered pairs are given as (0, 1), (1, 3), (2, 9), (3, 27).

Substitute the values in the general expression y = aˣ, all the pairs are satisfied for a = 3.

Thus, the correct option is found.

Hence, the set of ordered pairs which could be generated by an exponential function are (0, 1), (1, 3), (2, 9), (3, 27).

Answer:

x=9

Step-by-step explanation:

Looking at the diagram, we see that four angles are formed by the intersection of two lines. The angles highlighted in blue and green are therefore, vertical angles. We know that vertical angles have equal angle measures meaning that in this case, the measure of the blue angle is equal to the measure of the green angle. Using this, we can now solve for x:

7x+49=2x+94

7x-2x=94-49

5x=45

x=45/5

Step-by-step explanation:

The total surface area of the solid is 1466.4 square millimeters.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The rectangular prism has a total surface area of:

2lw + 2lh + 2wh

= 2(16)(11) + 2(16)(10) + 2(11)(10)

= 352 + 320 + 220

= 892 square millimeters.

2B + Ph

= 2(0.5bh) + (perimeter of base)h

= 2(0.5(11)(8)) + (11 + 8 + sqrt(11² + 8²))(16)

= 88 + 478.4

= 566.4 square millimeters.

Therefore,

The total surface area of the solid is:

892 + 566.4

= 1458.4 square millimeters,

which rounded to one decimal place is 1466.4 square millimeters.

Thus,

The total surface area of the solid is 1466.4 square millimeters.

Answer:

The ratio is 16/65

Step-by-step explanation:

In this question, we are tasked with calculating what ratio represents the cosine of the angle  Q.

In a right angled triangle, there are usually three sides, the hypotenuse, the opposite and the adjacent. Also, there are three angles, 2 asides the ∠90°. The hypotenuse is the longest side which faces the ∠90°, the opposite is that side facing the angle we are interested in while the adjacent is the third side.

Hence we can have only a single hypotenuse, which is the longest side, two opposites(depending on the angle we are concerned about and two adjacents two based on the angle of interest

Firstly, please check attachment for diagrammatic representation.

The ratio for the cosine of an angle is = length of adjacent/length of hypotenuse

From the diagram, with respect to angle Q, the length of the adjacent is 16 while the length of the hypotenuse is 65.

Thus, the ratio representing the cosine of angle Q is 16/65

Answer:

D - 150

Hope it helped :)

Answer:

150=w

Step-by-step explanation:

The answer is a little bit wordy. w = the sum of 85 + the supplement of 115.

So the first thing to do is get the supplement of 115.

180 - 115 = 65

w = 85 + 65 (These two are the remote interior angles. W is equal to the sum of them).

w = 150

Shannon's expression:

[tex]\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }[/tex]

Kristoph's expression:

[tex]\frac{4.2 \times 10^{2} }{1.4 \times 10^{-3} }[/tex]

Notice that both expression has the same coefficient numbers: 4.2 and 1.4. That means to have the same results, we just need to have the same powers.

Without dividing the complete expression, you can observe that both powers are the same, because each you subtract 9-4 = 5, and 2-(-3) = 5, both gives the same exponent to the power of 10.

Therefore, both expression give the same result, because they have the same numbers and the same powers.

Let's solve the division to have the result in scientific notation.

Shannon's expression:

[tex]\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4}=3 \times 10^{5}[/tex]

Kristoph's expression:

[tex]\frac{4.2 \times 10^{2} }{1.4 \times 10^{-3} }=3 \times 10^{2-(-3)}=3 \times 10^{5}[/tex]

The standard form refers to each number written without the power. To do so, we need to move the decimal points the number of spots as the exponent demands. Notice that the exponent is 5, that means, we need to move the decimal point 5 spots to the right.

[tex]3 \times 10^{5}=300000[/tex]

Therefore, the standard value of the expressions is 300,000.

[tex]\frac{x^{2} }{36}+\frac{y^2}{16}=1[/tex]

Step-by-step explanation:

Center of the ellipse is at origin (0, 0)

So (h, k) = (0, 0)

Length of major axis = 12

2a = 12

⇒ a = 6

Length of minor axis = 8

⇒ 2b = 8

⇒ b = 4

Since focus is on the x-axis, so it's a horizontal ellipse.

Equation of the horizontal ellipse is in the form of,

[tex]\frac{(x-h)^{2} }{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]

By substituting the given values of a, b, and (h, k)

Step-by-step explanation:

You haven't presented any diagrams, so I assume the prism has the dimensions shown below.

Then the dimensions of the original piece of cardboard are as in the second figure.

The area of the cardboard is the same as the lateral area of the triangular prism.

The formula for the area of a rectangle is  

A = lw

 l = 9 cm + 9 cm + 7 cm = 25 cm

w = 20 cm

A = 25 cm × 20 cm = 500 cm²

The area of the piece of cardboard is 500 cm².
