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]

Note 1 [tex]cm^{3}= 1 ml[/tex]

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.

Answer:

The value of x is 42°.

Step-by-step explanation:

Given AB and BC are perpendicular lines which means that AB is 90° to BC. So in order to find the value of x, you have to substract 24° and 24° from 90° :

[tex]24° + x + 24° = 90°[/tex]

[tex]x = 90° - 24° - 24°[/tex]

[tex]x = 42°[/tex]

Steps to solve:

-4(r + 3) = -42

~Distribute

(-4 * r) + (-4 * 3) = -42

~Simplify

-4r - 12 = -42

~Add 12 to both sides

-4r - 12 + 12 = -42 + 12

~Simplify

-4r = -30

~Divide -4 to both sides

-4r/-4 = -30/-4

~Simplify

r = 7.5

Answer: 77/50

Step-by-step explanation:

Decimal: 1.54

Fraction: 77/50

Percentage: 154%

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]

Actual dimension of the field = 42 ft × 21 ft

Equation : [tex]y=\frac{7}{2}x[/tex]

Step-by-step explanation:

Scale for the drawing of a rectangular playing field is,

2 inches = 7 feet

Or 1 inch = 3.5 feet

If length of the playing field on drawing = 12 in

Then actual length of the field = 12×3.5 = 42 feet

And width on the drawing = 6 inches

Therefore, actual width of the field = 6×3.5 = 21 feet

If 'x' is the dimension of a scale drawing and 'y' be the corresponding dimension of the actual field,

[tex]\frac{x}{y}=\frac{2}{7}[/tex]

[tex]y=\frac{7}{2}x[/tex]

Answer:

The ratio of the height of the cone to the height of the cylinder is 3 to 1

The ratio of the height of the cone to the radius of the sphere is 4 to 1

Step-by-step explanation:

First we need to know the volume of a cylinder, a cone and a sphere:

V_cylinder = pi*r^2*h

V_cone = (1/3)*pi*r^2*h

V_sphere = (4/3)*pi*r^3

If they have the same volume:

The ratio of the height of the cone to the height of the cylinder is:

V_cone / V_cylinder = 1

(1/3)*pi*r^2*h1 / pi*r^2*h2 = 1

(1/3) * h1 = h2

h1 / h2 = 3

So the ratio is 3 to 1

The ratio of the height of the cone to the radius of the sphere is:

V_cone / V_sphere = 1

(1/3)*pi*r^2*h / (4/3)*pi*r^3 = 1

h / 4r = 1

h / r = 4

So the ratio is 4 to 1

Answer:

Step-by-step explanation:

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

The amplitude of the cosine function "y = cos(x)" is 1. Therefore, the correct answer is "d. 1", as it represents the maximum absolute value of the function.

The function "y = cos(x)" represents a cosine function, and its amplitude is the maximum absolute value of the function. The amplitude of the cosine function "cos(x)" is 1. This is because the cosine function oscillates between -1 and 1, and the amplitude is the absolute value of this maximum value.

In mathematical terms, the amplitude (A) of a cosine function "A cos(x)" is equal to the absolute value of the coefficient of the cosine term. In this case, "A = |1| = 1".

We have the two rectangles on the sides which are 17 by 13 and the rectangle on the bottom which is 17 by 10

17* 13 + 17*13 + 17*10 =612

The total surface area of the composite figure will be 134 square units.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

The dimensions of figure

Now,

The area of the shared face is already calculated as 20 square units. So, to find the total surface area, we subtract this from the sum of the surface areas:

TSA=(60+94)−20

TSA=154−20

TSA=134

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.
