A hotel in Las Vegas, Nevada, is the largest pyramid in the United States. Prior to the construction of the building, the architects designed a scale model. The height of the scale model is 9 inches less than its length and its base is a square. If the volume of the model is 6300 cubic inches, write an equation describing the situation.

Answer:

f(t) = 5(4)^t

f(3) = 5(4^3) = 5 * 64 = 320

You can use the Pythagorean theorem to solve.

Distance = √(650^2 + 150^2)

Distance = √(422500 + 22500)

Distance = √(445000)

Distance = 667.08 miles

Rounded to the nearest whole mile = 667 miles.

The calculated distance is approximately 667.08 miles.

Calculating the Distance of the Eagle from Its Nest

To determine the distance of the eagle from its nest after flying 650 miles east and 150 miles south, we can use the Pythagorean theorem, which is applicable for right-angled triangles.

The eagle's eastward flight of 650 miles and southward flight of 150 miles form the two perpendicular sides of a right triangle, while the hypotenuse represents the straight-line distance from the nest.

The formula for the Pythagorean theorem is:

a² + b² = c²

Where:
a = 650 miles
b = 150 miles
c = the distance from the nest

Therefore, the distance of the eagle from his nest is approximately 667.08 miles.

Answer:

335.5 sq ft.

Step-by-step explanation:

Let's start with the 2 straight 10-feet long walls, it's easier.

Each of those two wall sections are 10 feet long by 9 feet high...  They're rectangles, so their area is their base (10) by their height (9).

Wall 1 = 10 x 9 = 90 sq ft

Wall 2 = 10 x 9 = 90 sq ft

Now the half-circle portion.

The trick here is to calculate half of the circumference. The circumference of a circle is given by C = 2 π r, but we only want half of it... so C/2 = π r

We have the radius (r = 5.5 ft).

So, the half circle has a (half) perimeter of: 5.5 π r = 17.28 ft

Then we multiply this by the height of 9 feet: 17.28 = 155.52 sq ft

Then we add the two other walls:

Total area = 90 + 90 + 155.52 = 335.52, which we round down to 335.5 sq ft.

Answer:

a) 4 - [tex]vt - d = \frac{1}{2} at^{2}[/tex]

b) 1 - [tex]2(vt - d) = at^{2}[/tex]

c) 6 - [tex]\frac{2(vt - d)}{t^{2}} = a[/tex]

Step-by-step explanation:

It simply asks the steps to go from the original displacement formula to isolate a (the acceleration).  It's just a matter of moving items around.

We start with:

[tex]d = vt - \frac{1}{2} at^{2}[/tex]

We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):

[tex]vt - d = \frac{1}{2} at^{2}[/tex]

Then we multiply each side by 2 to get rid of the 1/2, answer #1:

[tex]2(vt - d) = at^{2}[/tex]

Finally, we divide each side by t^2 to isolate a (answer #6):

[tex]\frac{2(vt - d)}{t^{2}} = a[/tex]

Answer:

169 : 289

Step-by-step explanation:

Since the figures are similar then

linear ratio of sides = a : b, then

ratio of areas = a² : b²

ratio of sides = 52 : 68 = 13 : 17

ratio of areas = 13² : 17² = 169 : 289

Answer:

(13.8,1.42) (18,3.7)(16.7,3.21) and so on REMEMBER ITS (X,Y)

Step-by-step explanation:

Answer: OPTION C

Step-by-step explanation:

Remember that:

[tex]\sqrt[n]{a^n}=a[/tex]

And the Product of powers property establishes that:

[tex]a^m*a^n=a^{(mn)}[/tex]

Rewrite the expression:

[tex]\frac{\sqrt{18x} }{\sqrt{32} }[/tex]

Descompose 18 and 32 into their prime factors:

[tex]18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2[/tex]

Substitute into the expression, then:

[tex]\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }[/tex]

Finally,simplifying, you get:

[tex]\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}[/tex]

If Willie ends up with only 20CDs that would be half of what he had at first and 20 plus 20 which would be the other half would be 40. 6 minus 40 would be 34 which he started with.

Answer:34

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

There is a rather simple method to this.

The factor given is ( x - 2 ) and the dividend is ( 2x⁵ - 7x³ - x² + 4x - 1)

To find the remainder, we will take it as x - 2 = 0

We will get x as 2

Now, substitute the value.

2 ( 2 )⁵ - 7 ( 2 )³ - ( x )² + 4 ( 2 ) - 1

2 ( 32 ) - 7 ( 8 ) - ( 4 ) + 8 - 1

64 - 56 - 4 + 8 - 1

8 - 4 + 8 - 1

16 - 4 - 1

16 - 5

11

Hence, the remainder is 11.

Answer:

First option: True.

Step-by-step explanation:

To know if the volume of this cylinder is 496.21 ft³, you need to use the formula for calculate the volume of a cylinder:

[tex]V=\pi r^2h[/tex]

Where "r" is the radius and "h" is the height.

You can observe in the figure that the radius of the cylinder is 4.5 feet and the height is 7.8 feet.

Then, knowing this, you can substitute these values into the formula.

Therefore, the volume of this cylinder is:

[tex]V=\pi (4.5ft)^2(7.8ft)\\V=496.21ft^3[/tex]

Then the answer is: True.

Answer:

  √33 cm ≈ 5.745 cm

Step-by-step explanation:

Let b represent the third side. If the third side is not the hypotenuse, then the longest of the given sides must be the hypotenuse. The Pythagorean theorem tells us ...

  4^2 + b^2 = 7^2

  b^2 = 49 -16 = 33 . . . . . . . . subtract 16

  b = √33 ≈ 5.745 . . . . . . . . . take the square root

The third side is √33 cm long, about 5.745 cm.

To find the length of the third side of a right triangle, apply the Pythagorean theorem by squaring the given sides and calculating the square root of their sum. In this case, the third side would be approximately 5.74 cm.

To find the length of the third side of a right triangle when the other two sides are 4 cm and 7 cm, you can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

Given sides are 4 cm and 7 cm

Let's assume the third side is x

Applying the Pythagorean theorem: 4² + x² = 7²

Solving for x: 16 + x² = 49 => x² = 33 => x = √33 cm

Therefore, the length of the third side is approximately 5.74 cm

Answer:

144 π  or 452.4 sq inches, for each dot

Step-by-step explanation:

We are given the perimeter of the circle (24π), and we are asked to find the area of the circle basically.

The Circumference of a circle is given by C = 2 * π * r

while its area is given by A = π r²

So, having the circumference, we can isolate r to use it in the area calculation.

C = 2  * π * r

24π = 2 * π * r  (now dividing both sides by 2π)

12 = r

The radius is 12 inches.

That means the area of one dot is:

A = π r² = π 12² = 144 π sq inches

The amount of blue glass needed for each dot is 144 π  or 452.4 sq inches

Answer: 144

Step-by-step explanation:

Answer:

The rule for finding a reflection of a point across the y-axis is that the y-coordinate will stay the same but the x-coordinate will become its opposite. Thus, in the context of the problem, point (3,6) would become (-3,6) if reflected across the y-axis.

Step-by-step explanation: If you were going to reflect a point across the x-axis, the x-coordinate would stay the same. You're not moving it and it shouldn't change signs. The y-coordinate, however, would become its opposite because it'd be joining a new quadrant. Think of it like this:

Y-AXIS = Y remains the same and gains a neighbor; X changes because it isn't the center of attention.

X-AXIS = X remains the same and gains a neighbor; Y changes because it isn't the center of attention.

Basically, the letter of the axis is the number that doesn't change.

The remainder is non-zero, so [tex]x-3[/tex] is not a factor of [tex]2x^3-4x^2-8[/tex] (or whatever the given polynomial is supposed to be)

The Remainder Theorem suggests that if you substitute '3' into the polynomial equation [tex]2x^3 - 4x^2 - 8x + 1[/tex], the result is -5, which is the same as the remainder of that polynomial equation divided by x - 3.

Eric used the Remainder Theorem in his calculation, which is a mathematical principle in algebra. It states that the remainder of a polynomial f(x), when divided by a linear divisor x - a, is equal to f(a). In this scenario, when he plugged '3' (the value of 'a') into the equation [tex]2x^3 - 4x^2 - 8x + 1[/tex], he obtained a resultant value of -5.

This indicates that when the polynomial [tex]2x^3 - 4x^2 - 8x + 1[/tex] is divided by x - 3, the remainder is -5. This remainder would also be the result if 3 substituted for x in the original polynomial equation, as per the Remainder Theorem.

There are 25 marbles: (12 red, 7 yellow, 5 blue, 1 white)

The probability of the first marble being red is 12/25 because there are 12 red marbles still available and no marbles are missing

The probability of the second marble being red is 11/24 because only 11 red marbles are available and 1 marble has already been selected from the pile

The probability of the third marble being red is 10/23 because only 10 red marbles are available and 2 marbles have already been selected from the pile

The probability of the fourth marble being red is 9/22 because only 9 red marbles are available and 3 marbles have already been selected from the pile
