Answer:

[tex]5400cm^{3}[/tex] more water could be added to the container before the container overflows

Step-by-step explanation:

The volume of the rectangular container is got by multiplying its given dimensions: Length X breadth X height

This will be  30 X 20 X 24 = [tex]14400 cm^{3}[/tex]

To find the volume of water inside the rectangular container, we will use the new height for our computation of volumes, keeping the length and breadth of the cylinder the same.

This will be [tex]30 \times 20 \times 15 =9000 cm^{3}[/tex]

The volume of water needed to be added until the container overflows will be got by subtracting the volume of water present in the container from the total volume of the container

[tex]14400 - 9000 =5400cm^{3}[/tex]

Answer:

  (x +4)^2 = 14

Step-by-step explanation:

The constant on the left wants to be the square of half the coefficient of the linear term:

  (8/2)^2 = 16

In order for it to be that value, we need to add 4 to the equation.

  x^2 +8x +12 +4 = 10 +4

  x^2 +8x +16 = 14 . . . . collect terms

  (x +4)^2 = 14 . . . . . . . write as a square

Answer:

(x+4)² - 14 =0

Step-by-step explanation:

x² + 8x + 12 =10

(x²+4²) - 4²+12 = 10

(x+4)² -4-10 = 0

(x+4)² - 14 =0

Note: When completing squares, in the equation above.

The surface area of the decoration is 126 inches².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

We have that, the holiday decoration is a construction from two square pyramids that are joined together at their bases.

Total surface area of a square pyramid = Area of the square + Area of 4 triangular faces

But total surface area of the decoration does not contain the area of the square base as it is joined together.

So surface area of the decoration = Area of 8 triangular faces

                                                        = 8 × ([tex]\frac{1}{2}[/tex] a l)

Here a is the length of the edge of the square and l is the slant height of the triangle.

Surface area = 4 a l

                     = 4 × 4.5 × 7

                     = 126 inches²

Hence the surface area of the decoration is 126 inches².

To find the surface area of the holiday decoration, calculate the sum of the areas of the two square pyramids. Use the formula Surface Area = Base Area + 2 * (0.5 * Base Perimeter * Slant Height) and substitute the given values to find the surface area. The surface area of the decoration is 146.25 square inches.

To find the surface area of the holiday decoration, you need to find the sum of the areas of the two square pyramids. The formula for the surface area of a square pyramid is given by:

Surface Area = Base Area + 2 * (0.5 * Base Perimeter * Slant Height)

Since the base is a square, the base area is equal to the side length squared. Therefore, the base area is 4.5 inches * 4.5 inches = 20.25 square inches.

The base perimeter is equal to 4 times the length of one side. Therefore, the base perimeter is 4 * 4.5 inches = 18 inches.

Plugging these values into the formula, we have Surface Area = 20.25 square inches + 2 * (0.5 * 18 inches * 7 inches).

Simplifying the expression, we get Surface Area = 20.25 square inches + 2 * 63 square inches = 146.25 square inches.

Answer:

120 Ways

Step-by-step explanation:

The permutation of the word 'cheese' considers the unique arrangements of its letters. Since 'e' repeats thrice, the permutations are calculated using the formula for a multiset, resulting in 120 unique permutations.

The term 'permutation' typically refers to the possible arrangements of a set of items when the order of these items is important. In the context of English and the word 'cheese,' permutation would normally mean all the distinct arrangements of the letters in the word. However, since the letters 'e' and 'c' repeat in the word 'cheese,' the number of unique permutations is less than it would be if all the letters were different.

To calculate the permutations of 'cheese' specifically, we would have to account for these repeated letters. With six letters total and the letter 'e' appearing three times, we would use the formula for permutations of a multiset: 6! / (3! 1! 1! 1!), where the factorials represent the number of times each distinct letter occurs.

The sets that represent proportional relationships are: B, C, and E.

Here's how we can determine which sets of points represent proportional relationships:
Set A:
Plot the points (1, 4), (3, 8), and (5, 9) on the graph.
Calculate the ratio of y to x for each point:
(4/1) = 4
(8/3) = (8/3)
(9/5) = (9/5)
As you can see, the ratios are not the same. Therefore, set A does not represent a proportional relationship.
Set B: (attachment 1)
Plot the points (3, 2), (6, 4), and (9, 6) on the graph.
Calculate the ratio of y to x for each point:
(2/3) = (2/3)
(4/6) = (2/3)
(6/9) = (2/3)
In this case, the ratios are all the same, which is 2/3. Therefore, set B represents a proportional relationship.
Set C: (attachment 2)
Plot the points (2, 2), (4, 4), and (6, 6) on the graph.
Calculate the ratio of y to x for each point:
(2/2) = 1
(4/4) = 1
(6/6) = 1
All the ratios are equal to 1. Therefore, set C represents a proportional relationship.
Set D:
Plot the points (1, 3), (2, 7), and (3, 8) on the graph.
Calculate the ratio of y to x for each point:
(3/1) = 3
(7/2) = (7/2)
(8/3) = (8/3)
The ratios are not the same. Therefore, set D does not represent a proportional relationship.
Set E: (attachment 3)
Plot the points (0, 0), (1, 2), (2, 4), and (4, 8) on the graph.
Calculate the ratio of y to x for each point:
(0/0) = undefined (division by zero)
(2/1) = 2
(4/2) = 2
(8/4) = 2
Ignoring the undefined ratio at (0, 0), we see that the ratios are all equal to 2. Therefore, set E represents a proportional relationship.

The arc length is a quarter of the circumference of the full circle, so 2πr/4.

The straight sides are both radii, so each length r.

Total perimeter

p = 2πr/4 + r + r = r(π/2 + 2)

We put in r=2, π=3.14 and get

p = (2(3.14/2 + 2)) = 3.14 + 4 = 7.14

Answer: 7.14 km

The perimeter is also known as the circumference. The formula for the circumference is C = pi x diameter.

Step 1) Find the diameter

d = r x 2

d = 2 x 2 = 4 km

Step 2) Find the whole circumference

C = pi x 4

C = 4pi km

Step 3) Find 1/4 of the circumference

4pi x 1/4 = 1pi

1pi = 3.14

Step 4) Add the sides not part of the arc

3.14 + 2 + 2 = 7.14

C = 7.14 km

Step-by-step explanation:

Answer:

cos2θ = -0.7041

Cos θ = -0.3847

Step-by-step explanation:

Firstly, we should understand that since θ is in quadrant 2, the value of our cosine will be negative. Only the sine is positive in quadrant 2.

Now the sine of an angle refers to the ratio of the opposite to the adjacent. And since there are three sides to a triangle, we need to find the third side which is the adjacent so that we will be able to evaluate the cosine of the angle.

What to use here is the Pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the adjacent and the opposite.

Since Sine = opposite/hypotenuse, this means that the opposite is 12 and the hypnotist 13

Thus the adjacent let’s say d can be calculated as follows

13^2 = 12^2 + d^2

169 = 144 + d^2

d^2 = 169-144

d^2 = 25

d = √25 = ±5

Since we are on the second quadrant, the value of our adjacent is -5 since the x-coordinate on the second quadrant is negative.(negative x - axis)

The value of cos θ = Adjacent/hypotenuse = -5/13

Cos θ = -5/13

Cos θ = -0.3846

Using trigonometric formulas;

Cos 2θ = cos (θ + θ) = cos θ cos θ - sin θ sin

θ = cos^2 θ - sin^2 θ

Cos 2θ = (-5/13)^2 - (12/13)^2

Cos 2θ = 25/169 - 144/169

Cos 2θ = (25-144)/169 = -119/169

Cos 2θ = -0.7041

There are four quadrants in a coordinate geometry.

The cosine values are [tex]\mathbf{ cos(\theta)=- \frac{5}{13}}[/tex] and [tex]\mathbf{ cos(2\theta) = -\frac{119}{169}}[/tex]

The given parameter is:

[tex]\mathbf{sin(\theta) = \frac{12}{13}}[/tex]

Using trigonometry ratio, we have:

[tex]\mathbf{sin^2(\theta) + cos^2(\theta)= 1}[/tex]

Substitute [tex]\mathbf{sin(\theta) = \frac{12}{13}}[/tex]

[tex]\mathbf{(\frac{12}{13})^2 + cos^2(\theta)= 1}[/tex]

Expand

[tex]\mathbf{\frac{144}{169} + cos^2(\theta)= 1}[/tex]

Collect like terms

[tex]\mathbf{ cos^2(\theta)= 1-\frac{144}{169}}[/tex]

Evaluate fraction

[tex]\mathbf{ cos^2(\theta)= \frac{25}{169}}[/tex]

Take square roots of both sides

[tex]\mathbf{ cos(\theta)= \pm \frac{5}{13}}[/tex]

The angle is in the second quadrant.

So, we have:

[tex]\mathbf{ cos(\theta)=- \frac{5}{13}}[/tex]

Also, we have:

[tex]\mathbf{ cos(2\theta) = cos^2(\theta) - sin^2(\theta)}[/tex]

So, the equation becomes

[tex]\mathbf{ cos(2\theta) = \frac{25}{169} - \frac{144}{169}}[/tex]

Take LCM

[tex]\mathbf{ cos(2\theta) = \frac{25-144}{169}}[/tex]

[tex]\mathbf{ cos(2\theta) = -\frac{119}{169}}[/tex]

Hence, the values are:

[tex]\mathbf{ cos(\theta)=- \frac{5}{13}}[/tex] and [tex]\mathbf{ cos(2\theta) = -\frac{119}{169}}[/tex]

Step-by-step explanation:

Only Set 3 forms a right triangle as it satisfies the Pythagorean theorem, with side lengths matching the equation (√3)^2 + 4^2 = (√5)^2.

The question is about determining which set of side lengths will form a right triangle. To form a right triangle, the side lengths must satisfy the Pythagorean theorem, where the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides (a^2 + b^2 = c^2).

Let's check each set of side lengths:

Set 1: 62 + 72
eq (√12)2 (Not a right triangle)

Set 2: 82 + (√29)2
eq (√35)2 (Not a right triangle)

Set 3: (√3)2 + 42 = (√5)2 (Right triangle)

Set 4: 92 + (√26)2
eq 62 (Not a right triangle)

Therefore, only Set 3 forms a right triangle because it is the only set that satisfies the Pythagorean theorem.

Final answer:

To rewrite expressions as a power of 2, one needs to understand exponent rules and binary representation. Squaring exponentials involves squaring the base and multiplying the exponent by 2. Simplification often involves adjusting prefactors and exponents while keeping the expression equivalent.

Explanation:

To rewrite expressions as a power of 2, it's important to understand how to manipulate exponents and to be familiar with the binary representation of numbers. For instance, squaring exponentials involves squaring the base number and multiplying the exponent by 2. As an example, if you have (23)4, it is the same as 23×4 or 212.

When dealing with decimal equivalents of powers of two, such as 1837, which can be written as (1 × 1024) + (1 × 512) + (1 × 256) + (0 × 128) + (0 × 64) + (1 × 32) + (0 × 16) + (1 × 8) + (1 × 4) + (0 × 2) + (1×1), the expression is already in powers of two. Similarly, recognizing patterns can help simplify expressions, for example, 24 × 1012 can be simplified by adjusting the prefactor and exponent to maintain equivalence.

Finally, powers are applied to everything inside parentheses. For instance, (27×3) and (4×22) becomes 2.1 × 10-33 when raised to the proper power.

Answer:

The length of the equal side is 27 meters each and that of the unequal side is 36 meters

Step-by-step explanation:

An isosceles triangle is a triangle with two sides being equal (also two equal base angles).

Let us assume the length of the two equal sides to be x meters each, and the length of the unequal side to be y meter. Since the perimeter of the triangle is 90 m, it can be expressed as:

x + x + y = 90

2x + y = 90

But the length of the equal side is  three fourth of the unequal side, i.e x = 3/4y

Therefore:

2(3/4y) + y = 90

3/2y + y = 90

2.5y = 90

y = 90/2.5

y = 36 meters

Also x = 3/4 * 36 = 27 meters

The length of the equal side is 27 meters each and that of the unequal side is 36 meters

Step-by-step explanation:

Answer:

The reason why both have the same value is because you are only moving the decimal place. The difference between 51.2 and 5.12 is that you divided 10 from 51.2 to get 5.12. Same goes for 6.4 and 0.64.

51.2 / 6.4 = 8

5.12 / 0.64 = 8

Final answer:

The quotient of 51.2 divided by 6.4 is the same as 5.12 divided by 0.64 because both numerators and denominators are related by a factor of 10. This maintains the value of the quotient unchanged when both are multiplied or divided by the same power of 10.

Explanation:

When dividing two numbers, you can often simplify the expression by dividing both numbers by a common factor. In this case, both 51.2 and 6.4 have a common factor of 0.64. Dividing both numbers by 0.64, we get:

51.2 ÷ 0.64 = 80

6.4 ÷ 0.64 = 10

So, as you can see, the result is the same: 80 divided by 10 is equal to 8. This is why dividing 51.2 by 6.4 has the same value as dividing 5.12 by 0.64.
