The $8.78 more interest is owed on $900 for 9 months than 6 months.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

(a)

The formula for simple interest:

I = Prt

I(for 9 months) = 900x(2.9/100)(9/12)

I(for 9 months) = $19.575 = $19.58

I(for 6 months) = 900x(2.4/100)(6/12)

I(for 6 months) = $10.8

Difference = $19.58 - $10.8 = $8.78

(b)

From the table: the interest rate from 6 months to 9 months increases by 0.5% after that it increases constantly.

Thus, the $8.78 more interest is owed on $900 for 9 months than 6 months.

The equation of the line passing through point P(-1,-4) that is parallel to y = -6x + 8 is y = -6x - 10.

A straight line is made up of an infinite number of points connected at their ends.

Any straight line's slope, "m," is determined by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The slope of the line y = -6x + 8

m = -6

The slope of the line passing point P (-1,-4)

M = -6

y - (-4) = -6(x - (-1))

y + 4 = -6(x + 1)

y = -6x - 10

Thus, the equation of the line passing through point P(-1,-4) that is parallel to y = -6x + 8 is y = -6x - 10.

Step-by-step explanation:

The volume of the tank is 15315.35

Volume is a measurement of three-dimensional space that is occupied. [1] Numerous imperial units or SI-derived units, such as the cubic meter and liter, are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship. The volume of a container is typically thought of as its capacity, not as the amount of space it takes up.

Given that,

Top Outlet Tank

Height (h): 2550 mm

Diameter (d): 2100mm

radius (r) : 2.1/2

Mass: 650kg

The volume, in cubic metres, of the tank is

volume of tank = 2π + π[tex]r^{2} h[/tex]

= 2π(1100) + π(2.1/2)(2550)

= 2(3.14)1100+ (3.14)(2.1/2)(2550)

= 6908+ 8407.35

= 15315.35

Therefore, the volume of the tank is 15315.35

r = common ratio

Lets check:

The sequence is 80, 40, 20, 10,....

a₁ = 80

a₂ = 40

a₃ = 20

a₄ = 10

Now, lets find the common ratio:

Answer:

Step-by-step explanation:

Given,

The marked price of a jacket at dealer shop is Rs. 2400

The dealer allows a discount of 15% to the retailer.

The marked price of the retailer should be same as the dealer's marked price.

To find,

1. SP the retailer should fix for the jacket

2. Its final price if 10% VAT is imposed

3. The actual gain of the retailer if 10% discount is allowed

Solution,

The SP rate for the jacket without VAT 2400

Let 10% VAT on jacket price 2400 be x

x= 2400÷10

x= 240

So, the final price including 10% VAT = 2640 (2400+240)

As the dealer allowed discount of 15% to the retailer, the retailer gain profit is 15% on the jacket price i.e., 2400

Let y be the gain of the retailer

y= 15/100 × 2400

y= 360

Therefore,

SP the retailer should fix for the jacket is 2400

final price if 10% VAT is imposed is 2640

the actual gain of the retailer is 360

The function that has the greater slope is the function g(x) that is represented by the graph.

The slope (m) of a function using two points on a graph can be calculated as:

Slope of the line (m) = change in y/change in x

If we are given the equation of the line using function notation as .f(x) = mx + b, the slope of the function is represented in the equation as "m". The value of "m" is the slope of the function given.

Given the function, .f(x) = 3x + 1, the value that represents "m" which is 3. Therefore, the slope of the function .f(x) = 3x + 1 is: 3.

Find the slope of the function of the graph using two points on the line, say (2, 3) and (3, 7):

Slope of the function (m) = change in y / change in x = (7 - 3)/(3 - 2)

Slope of the function (m) = 4/1

Slope of the function (m) = 4

The larger the value of the slope, the greater the slope of the function.

Therefore, the function g(x) that is represented by the graph has a greater slope.

It is true but incomplete, a percent is found by dividing the percentage by the base and multiplying it with 100.

What is percentage?

Percentage is a relative value that represents hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

Divide the percentage by the quantity to get the percent of a number, then multiply the result by 100. Put the word "percent" (%) after the finished item.

Example of calculation of percentage:

What percent of 10 is 7?

here, 7 is percentage and 10 is quantity, On dividing we get,

7/10 = 0.7

Now multiplying by 100, we get

The value of the greatest integers will be 5.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The algebraic expression is,

'' An integer is subtracted from 5 times the next consecutive odd integer, the difference is 22''.

Now,

Write the mathematical expression for an algebraic expression as;

Let an integer = 2x + 1

Then, The next consecutive odd integer = 2x + 3

So, We can formulate;

5 (2x + 3) - (2x + 1) = 22

Solve for x as;

5 (2x + 3) - (2x + 1) = 22

10x + 15 - 2x - 1 = 22

8x + 14 = 22

Subtract 14 both sides, we get;

8x + 14 - 14 = 22 - 14

8x = 8

Divide by 8,

x = 8/8

x = 1

Since, The greatest integers = 2x + 3

Substitute x = 1, we get;

The greatest integers = 2x + 3

The greatest integers = 2 × 1 + 3

The greatest integers = 2 + 3

The greatest integers = 5

Therefore, The value of the greatest integers will be 5.

Using the mathematical operation of addition, the temperature in the thermometer, if it rises by 45°F, is (d) 30°F.

Mathematical operations use operands to combine with numbers and variables in a function so that they can produce results.

Some of the mathematical operations are addition, subtraction, division, and multiplication.

The temperature before the rise = -15°F

The temperature change = +45°F

The temperature after the rise = 30°F (-15°F + 45°F)

Thus, after adding the rise in temperature to the initial temperature, the new temperature in the thermometer is 30°F.

The constraints of a linear programming issue must all be concurrently satisfied for a solution to be viable. We are aware that the ideal solution must maximize the value of the goal function and be located at one of the corners of the feasible region.

All of the constraints on the problem are met by a feasible solution. A feasible answer that, when maximized, yields the highest possible value for the objective function is known as an optimum solution (or smallest when minimizing). A linear program with two variables can be solved using a visual solution method.

A fundamental feasible solution (BFS), according to the theory of linear programming, is a solution with a small number of non-zero variables. Each viable solution polyhedron's corner correlates geometrically to a BFS. There must be an optimal BFS if there is an optimal solution. Therefore, taking into account the BFS-s is adequate to arrive at an ideal solution. The simplex algorithm, which effectively moves from one BFS to another until one is found that is optimal, makes use of this property.
