The work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium is 34,300 J.

First we need to calculate the total amount of water that needs to be lifted and the height it needs to be lifted to.

The volume of water in the aquarium is given by:

V = 7 m * 1 m * 1 m = 7 m^3

Since we need to pump out the top half of the water, the volume of water that needs to be lifted is:

V = (1/2) * 7 m^3 = 3.5 m^3

The mass of the water can be calculated as:

m = V * density of water = 3.5 m^3 * 1000 kg/m^3 = 3500 kg

The height that the water needs to be lifted to is equal to the height of the aquarium, which is 1 m.

The work needed to lift the water can be calculated using the formula:

W = m * g * h

where

So, the work needed is:

W = 3500 kg * 9.8 m/s^2 * 1 m = 34,300 J (joules)

Therefore, the work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium is 34,300 J.

The values of the variable are:

x is 45.

y is 18.

z is 18.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

From the figure,

Sin 45 = z / (18√2)

Sin 45 = 1 /√2

So,

1/√2 =z / 18√2

z = 18

Cos 45 = y / (18√2)

1/√2 = y/18√2

y = 18

Tan x = y / z

Tan x = 18/18

Tan x = 1

x = [tex]tan^{-1}[/tex]1
x = [tex]tan^{-1}[/tex] tan 45

x = 45

Answer: 1/4

Step-by-step explanation:

To find the product of two fractions, you simply multiply the numerators together and multiply the denominators together. That is:

(5/8) x (6/15) = (5 x 6) / (8 x 15)

Simplifying the numerator and denominator by dividing both by their greatest common factor, which is 2, we get:

(5 x 6) / (8 x 15) = 30 / 120

Further simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, which is 30, we get:

30 / 120 = 1 / 4

Therefore, the product of 5/8 and 6/15 is 1/4.

Answer:

To multiply two fractions, you simply multiply their numerators (top numbers) and denominators (bottom numbers), respectively.

So, 5/8 x 6/15 = (5 x 6) / (8 x 15) = 30 / 120

To reduce this fraction to its simplest form, we can divide both the numerator and denominator by their greatest common factor, which is 30.

30 / 120 = (30 ÷ 30) / (120 ÷ 30) = 1/4

Therefore, the product of 5/8 x 6/15 is 1/4

The average speed with the given distance and time is 119/40 miles per hour.

Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.

Given that, number of miles jogged = [tex]3\frac{2}{5}[/tex] = 17/5 miles and the time taken = 7/8 hours

If the triangles are similar but no congruent, then the triangles have different size, thus the only correct option is the dilation (first option).

We know that two figures are congruent if the figures have the same shape and size, while two figures are similar only if have the same shape (but the figures can have different size).

Here we know that the triangles are similar but no congruent, so the triangles must have different size. From the given transformations, the only one that changes the size is the first option, a dilation.

The antiderivative of 1x (or simply x) is (1/2)x² + C, where C is the constant of integration. In other words, the antiderivative of x is the function whose derivative is equal to x.

This is a basic result in calculus, and it is derived using the power rule of integration. The antiderivative of 1x (or simply x) is the function whose derivative is equal to x. This function is (1/2)x² + C, where C is the constant of integration. To find the antiderivative, one can use the power rule of integration, which states that the antiderivative of xⁿ is (1/(n+1))x⁽ⁿ⁺¹⁾ + C. In the case of x, n is equal to 1, so the antiderivative is (1/2)x² + C. The constant of integration represents the family of functions that have the same derivative, so it is added to the antiderivative to reflect this.

The ratio of trombones to all the brass section members is 3:7.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

2/10 Net 30 represents credit given to the buyer for the sale of goods or services. 2/10 net 30 means that the customer gets a 2% discount if the outstanding balance is paid within 10 days. Otherwise, full payment is due within 30 days.

2/10 Net 30:

The terms and conditions of the transaction are set forth in the purchase order and the corresponding invoice. These terms include terms of credit between the seller (also known as the payee) and the buyer (also known as the payer). A typical net credit period of 30 means the balance must be paid within 30 days of the invoice date. 2/10 Net 30 (also known as 2 10 Net 30) means that if a buyer pays within the first 10 days, their balance will be reduced by 2%. So "2" is the discount amount (2%) and "10" is the due date (10 days).

For example, if your company purchased $500 worth of goods or services on June 1st, you have entered into a loan agreement with the seller. If your company pays the net amount between June 1st and June 10th, you get a 2% discount, bringing the total amount to $490.

The amount the the home buyer saves in total by choosing Loan A is  most closest to $11,427. The Option B is correct.

In order to compare the total cost of each loan, we need to consider both the monthly payment and the discount points.

For Loan A, we have Loan amount: $390,000, Loan term: 15 years, Discount points: 4 and Monthly payment: $3,509.71. For Loan B, we have Loan amount: $390,000, Loan term: 15 years Discount points: 0 and  Monthly payment: $3,659.86.

The total cost of Loan A is the sum of the discounted upfront cost (discount points) and the total of all monthly payments over the life of the loan:

= (4% of $390,000) + ($3,509.71 x 180)

= $15,600 + $631,948.80

= $647,548.80

The total cost of Loan B is the total of all monthly payments over the life of the loan:

= ($3,659.86 x 180)

= $658,574.80

Now, the amount saved by choosing Loan A over Loan B is the difference between their total costs which equals:

= Total cost of Loan B - Total cost of Loan A

= $658,574.80 - $647,548.80
