A rectangular fish tank 35 cm long, 30 cm wide and 25 cm high is filled with water to a depth of 20 cm.
Find the volume of water in the fish tank.

Give your answer in liters.

Answer:

  0.67 million miles per day

Step-by-step explanation:

You want the average rate of change of the function d(t) = ∛(6t²) on the interval [4, 8], where d is in millions of miles, and t is in days.

The average rate of change of the function on the interval [a, b] is given by ...

  rate of change = (d(b) -d(a))/(b -a)

As the table in the attachment shows, this is approximately ...

  rate of change = (7.268 -4.579)/(8 -4) ≈ 0.67

The average rate of change on the interval 4 ≤ t ≤ 8 is about 0.67 million miles per day.

Additional comment

Mercury has an orbit of about 88 days at a distance of roughly 36 million miles from the Sun. Already at that distance, the General Theory of Relativity comes into play, making predictions from Newtonian physics somewhat problematic. It is unlikely this formula has any relation to reality for t much less than 200.

Answer:

To find out how many 1 1/2 foot boards can be cut from a 12 foot long board, we need to divide the length of the board by the length of each board.

First, we need to convert 1 1/2 feet to an improper fraction.

1 1/2 = (2 x 1 + 1) / 2 = 3/2

So, each board is 3/2 feet long.

Next, we divide the length of the 12 foot long board by the length of each board:

12 / (3/2) = 12 x 2/3 = 24/3 = 8

Therefore, 8 boards of length 1 1/2 feet can be cut from a 12 foot long board.

1. AB is a tangent, the triangle is a right triangle

2. AB is  not a tangent, the triangle is not a right triangle and hence not a Pythagorean triple

3. arc RS = 100 degrees

4. arc ST =  80 degrees

5. arc RTS = 260 degrees

6. arc RST = 180degrees

7. x = 3

8. x = 7

A tangent will obey Pythagorean triple hence we have that

AB^2 = AC^2 + BC^2

1. AB^2 = 24^2 + 10^2 = 676

AB = sqrt (676) = 26. hence AB is a tangent

2. AB^2 = 8^2 + 11^2 = 185

AB = sqrt (185) = 13.6. hence AB is not a tangent

Length of arc

3. arc RS = 100 degrees (central angle equals intercepted arc)

4. arc ST = 180 - arc RS = 180 - 100 = 80 degrees

5. arc RTS = 180 + arc ST = 180 + 80 = 260 degrees

6. arc RST = 180degrees (semicircle)

Value of x

7. x + 8 = 5x - 4

8 + 4 = 5x - x

12 = 4x

x = 3

8. 4x + 5 = 6x - 9

4x - 6x = -9 - 5

-2x = -14

Step-by-step explanation:

There is a financial advantage of $ 1,187,520.

Incremental Costs and Revenues will be as follows

Increment in sales = 82,000 units × 40% = 32,800 units

and, Selling Price

= (32,800 units × $62 per unit)

= $ 2,033,600

Direct materials

= $ 7.50 × 32,800 units

= 246,000

Direct labor

= $ 9.00 × 32800

= $295,200

and, Variable manufacturing overhead

= 2.40 x 32800

= $78, 720

So, the contribution is

= 2,033,600 - (246000 + 285200 + 78720)

= 1,423,680

Now, Variable selling expenses

= 32800 x 3.7

= 121,360

and, Fixed Selling Expenses

= 32800 x 3.5

= 114,800

So, Net income = 1, 187, 520

The triangles are not similar. Triangle EFG and Triangle QRS are not similar. ΔEFG not ~ ΔQRS

From the question, we are to determine if the given triangles are similar

From one of Triangle similarity theorems, AA (or AAA) or Angle-Angle Similarity theorem.

The Angle-Angle similarity theorem states that If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other

In the given diagram,

In triangle EFG

m ∠E = 104°

m ∠F = 45°

m ∠G = 180° - (104° + 45°) = 31°

In triangle QRS

m ∠R = 100°

m ∠Q = 45°

m ∠S = 180° - (100° + 45°) = 35°

Since no two angles of one of the triangles are equal to any two angles of other triangle, the triangles are not similar

The probability of getting hearts or face cards is 25/52.

We know that, Probability of an event = Number of favorable outcomes/Total number of outcomes.

Total number of outcomes = 52 cards

Number of hearts = 13

Number of face cards = 12

Probability getting hearts = 13/52

Probability getting face cards = 12/52

P(Hearts or Face card) = 13/52 + 12/52

Answer:

C. complementary

Michel-Eugène Chevreul discovered that placing complementary colors next to each other can create the greatest contrast and vibrancy in color perception. This is because complementary colors are located opposite each other on the color wheel and, when placed side by side, they enhance each other and create a strong visual impact. For example, placing yellow next to violet or blue next to orange can create a dynamic and eye-catching effect. In contrast, placing tertiary colors (colors made by mixing primary and secondary colors) or arbitrary colors next to each other may not create as much contrast or visual interest. Overall, understanding color theory and the relationships between different colors can be helpful for creating visually appealing designs, artworks, or other color-based projects.

The future value or the total amount due at time t for the loan is $5112.50.

To find the future value or the total amount due at time t for a loan with a principal P, a simple interest rate r, and a period of time t, we can use the formula for calculating simple interest;

A=P + (P × r × t)

where; A = future value or total amount due at time t

P = principal amount

r = simple interest rate

t = time period (in years)

Given the values; P = $5000

r = 4.5% (or 0.045 as a decimal)

t = 6 months (or 0.5 years)

We can substitute these values into the formula and calculate the future value;

A = 5000 + (5000 × 0.045 × 0.5)

A = 5000 + 112.5

A = $5112.50

The Perimeter of the given figure rectangle will be 60m. The correct option is 1.

Perimeter refers to the total length of the boundary of a two-dimensional shape or object. It is the distance around the edge of a shape. To find the perimeter of a shape, you add up the lengths of all its sides.

The perimeter of a rectangle is given by the formula:

P = 2(l + w)

where P is the perimeter, l is the length, and w is the width.

Using the values you provided, we can substitute them into the formula:

P = 2(18 + 12) = 2(30) = 60 meters

Therefore, the perimeter of the rectangle with a length of 18 meters and a height of 12 meters is 60 meters.

Let's call the height of the second building "x". We can use trigonometry to solve for x.

First, let's draw a diagram to help visualize the problem:

A        B

\      /

 \    /

  \  / x

   \/

   C

Where:

A is the top of the 200 meters high building

B is the bottom of the second building

C is the point from which the angles of depression and elevation are measured

x is the height of the second building

From the diagram, we can see that:

angle BCA = 20 degrees (angle of depression)

angle BAC = 10 degrees (angle of elevation)

AB = 200 meters

Using the tangent function, we can write:

tan(20) = x / AB (tangent of angle BCA)

tan(10) = x / (AB + x) (tangent of angle BAC)

We can solve these equations for x:

x = AB * tan(20) (multiply both sides by AB)

x = (AB * tan(10)) / (1 - tan(10)) (multiply both sides by 1 - tan(10), then simplify)

Plugging in the values we know:

x = 200 * tan(20)

x = (200 * tan(10)) / (1 - tan(10))

Using a calculator:

x ≈ 67.35 meters

Therefore, the height of the second building is approximately 67 meters (to the nearest hundred meters).

8x^5 = 4x^2*2x^3

12x^3 = 4x^2*3x

20x^2 = 4x^2*5

This shows how 4x^2 is the GCF of 8x^5, 12x^3, and 20x^2

-----------------

Here's how to find the GCF of terms involving variables.

First, find the GCF of the coefficients 8, 12 and 20.

List the prime factorizations

Then circle "2*2" since it is found in all three factorizations. Do not circle 3 because it's not found in 8 or 20. Do not circle 5 since it's not found in 8 or 12.

Therefore, the GCF of {8,12,20} is 2*2 = 4.

As for the variable terms, we look for the smallest exponent.

The exponents for x^5, x^3, x^2 are 5,3,2 in that order. The smallest exponent is 2, so x^2 is part of the GCF.

----------------

Summary:

We found the GCF of the coefficients was 4.

The GCF of the variable terms was x^2
