Principal is $6000.

Define simple interest.

Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows $5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years. Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.

Given Data

Using simple interest formula,

| = $14,400

R = 8%

T = 30 years

I = [tex]\frac{PRT}{100}[/tex]

14400 = [tex]\frac{P(8)(30)}{100}[/tex]

[tex]\frac{14400(100)}{8(30)}[/tex] = P

By the end of her three turns, she is level 5.

The number line is what?

A number line is a visual depiction of numbers on a straight line in mathematics. A number line's numerals are arranged in a sequential manner at equal intervals along its length. It is often displayed horizontally and can extend indefinitely in any direction.

If Rebecca cuts down six trees on her next round, she drops down to level four and gains six levels. Rewriting this as -6 yields 4 + (-6) = -2. her following turn, she will plant 8 trees, increasing her level by 8. -2 + 8 = 6 In her final round, she removes one tree.

6 + (-1) = 5

4 + (-6) + 8 + (-1) = 5 in total.

The surface areas of two similar figures are 16 in2 and 25 in2. If the volume of the larger figure is 500 in3, what is the volume of the smaller figure?

Answers

The volume of the smaller figure is 256 in³.

Given, the surface area of two figures are 16 and 25.

volume of the larger figure is 500.

volume of smaller figure =?

Similar figures have a scale factor k, (let k be >1, so k is the ratio of a distance in the larger figure to the corresponding distance in the smaller one)

First, we calculate for the ratio of the surface areas of the given figures. From the given above, the ratio is equal to 25:16

Then, we calculate for the ratio of the perimeters or sides of the figures by getting the square root of the ratio in figure 1.

             ratio of perimeter or side   = 5:4

The ratio of the volumes of the figures is equal to the cube of the ratio in figure 2.

              ratio of volumes = (5:4)³ = 125:64

Using this ratio and the volume of the larger figure,

                      500 in³/x in³ = 125/64

                                  x in³ = 500×64/125

                                  x in³ = 256 in³

 

The value of x from the equation is 256. Therefore, the volume of the smaller figure is 256 in³.

Answers

The solution of the quadratic equation (1/3)x² - (1/9)x - 2/9 = 0 are x = 1, - 2/3.

Any equation that can be written in the standard form where x stands for an unknown and a, b, and c are known quantities, with a 0, is said to be quadratic.

An assignment of values to the unknown variables that establish the equality in the equation is referred to as a solution.

Consider the expression,

(1/3)x² - (1/9)x - 2/9 = 0

Multiplying each side of the quadratic equation by 9,

9 × [ (1/3)x² - (1/9)x - 2/9 = 0 ]

3x² - x - 2 = 0

Using the quadratic formula,

[tex]x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]x = \frac{1 \pm \sqrt{1+24} }{6}\\ x = \frac{1 \pm \sqrt{25} }{6}[/tex]

x = 1 and x = - 2/3

If we label the given points to find the slope of the line, we have:

Then, using the formula for the slope of a line, we have:

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{7-1}{-2-4}=\frac{6}{-6}\Rightarrow m=-1[/tex]

Then, having this value of m, we can apply the formula for the Point-Slope Form of the line:

1. In the case we take the pair as ( 4, 1), the equation is:

[tex]y-y_1=m(x-x_1)=y-1=-1(x-4)=y-1=-(x-4)[/tex]

To the nearest tenth of a second, how much time would it take the penny to hit the ground?

Answers

In this problem, we want to approximate when a penny will hit the grownd after it has been dropped from the back of the bleachers.

Since we have been given a table, we can make a close estimate based on the y-values.

When the penny hits the ground, the value of y will be 0.

Notice on the table provided that the penny is going to reach 0 between the values of 0.6 and 0.7 seconds.

At 0.6 seconds, it has a distance of 0.236 meters from the ground.

At 0.7 seconds, supposing the penny went past hitting the ground, it was have a distance of

[tex]|-0.401|=0.401\text{ meters from the ground.}[/tex]

Since the penny is closer to 0 at the 0.6 s mark than the 0.7 s mark, we can say 0.6 seconds is when the penny will hit the ground.

The maximum load of a horizontal beam that is supported at both ends varies jointly as the width and the height and inversely as the length between the supports. A beam 6m long, 0.1m wide, and 0.06 m high supports a load of 360kg. What is the maximum load supported by a beam 16m long, 0.2m wide, and 0.08 m high?

Answers

Answer:

[tex]360kg[/tex]

Explanation:

Here, we want to get the maximum load supported

From the first part of the question, we have it that:

The maximum load g, varies jointly with the width w and the height h, and inversely as the length l between the supports

Mathematically, we have that as:

[tex]g\text{ = k }\times\frac{wh}{l}[/tex]

where k is the proportionality constant

Now, let us get the value of k

We substitute the first set of values as follows:

[tex]\begin{gathered} 360\text{ = }\frac{k\times0.1\times0.06}{6} \\ \\ k\text{ = 360,000 }\frac{kg}{m} \end{gathered}[/tex]

Now, using this value of k, we want to get the value of g

Mathematically, we have that as:

[tex]g\text{ = }\frac{360,000\times0.2\times0.08}{16}\text{ = 360 }kg[/tex]

What is the x and y intercepts of the line 2x-5y=20

Answers

The x-intercept and the y-intercept of the original equation of line 2x-5y=20 is (10,0) and (0,-4).

What is defined as the x and y intercepts?An intercept is a y-axis point by which the slope of a line passes. It is the y-coordinate of a point on the y-axis in which a straight line or a curve intersects. This is represented by the equation for a straight line, y = mx+c, where m is the slope as well as c is the y-intercept.

The x-intercept occurs where y=0, and the y-intercept occurs where x=0.

2x-5y=20 is the original equation of the line.

1) Substitute 0 for y to obtain 2x - 5(0) = 20, that equals 2x = 20.

Now, find x by dividing all sides by 2, and x = 10, resulting in the x-intercept (10,0)

2) Substitute 0 for x to obtain 2(0) - 5y = 20, which equals -5y = 20.

Now, find y by dividing all sides by 5, and y = -4, implying that the y-intercept is (0,-4).

Thus, the x-intercept and the y-intercept of the original equation 2x-5y=20 is (10,0) and (0,-4).

You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 201 km south and 160 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM. If you are flying at a constant speed of 800 km/hr, how long after you depart JBLM will you be the closest to Mt. Rainier?

Answers

The time it would take to get closest to Mt Rainier, t ≈ 8.53 × [tex]10^{-3}[/tex] hours.

What is the separation of a line from a point?

The perpendicular distance of a point to a line is the closest distance between them. The length of the perpendicular segment connecting a point to a line is the distance between them.

It would take roughly 5.12 minutes to go to the closest point to Mount Rainier.

The following justifies why the value is accurate:

The given parameters are;

The flight's direction is 201 kilometres south and 160 km east.

Mount Retainer is situated 56 kilometers east and 40 kilometers south of JBLM.

Flight velocity is 800 km/h.

The travel path's slope, in m, is given as follows:

m = -201/160

=1.2

The equation of the path is therefore;

y+201 = -1.2(x-160)

y = -1.2(x-160) - 201

The required slope for the perpendicular distance from the travel path to the Mt Rainier, m', is therefore;

m' = -1/m

Which gives;

m' = 1/1.2

The equation of the line is therefore;

y+ 40 = 1/1.2(x-56)

y = 1/1.2(x-56)-40

The coordinates of the point where the two lines meet is therefore;

-1.2(x-160)-201 = 1/1.2(x-56)-40

solving this we get

x = 22.46

y = -67.83

The magnitude of the distance in km is, d = 71.451

The time it will take to be closest to Mt. Rainier, t, is given as follows;

t = 71.451/800

t = 8.9×[tex]10^{-3}[/tex]

The time it would take to get closest to Mt Rainier, t ≈ 8.53 × [tex]10^{-3}[/tex] hours.

Answers

After solving the equation, Clifford need 3.75 cups of flour, 2.5 cups of sugar and  1.25 cups of butter to make the cake.

What is an equation?

Equation, also referred to as a declaration of equality between two expressions that contain variable- and/or number-based components. Since equations are essentially questions, the development of mathematics has been driven by efforts to systematically find answers to those questions.

There are many different types of equations that vary in complexity, ranging from simple algebraic equations that only call for addition or multiplication to differential equations, exponential equations that employ exponential expressions, and integral equations. They serve as an expression for many physics laws.

Let flour be f, sugar be s, and butter be b

We have given that

f = 1.5s       ...1

b = 1/2(s)

    = 0.5s   ...2

And

F + B + S = 7.5 cups

Lets substitute the vales of f and b in F + B + S, and we get

1.5s + 0.5s + S = 7.5 cups

2S + S = 7.5

3S = 7.5

S =  7.5/3

S = 2.5 cups

Flour = (1.5)2.5

         = 3.75 cups

Butter = (0.5)2.5

          =  1.25 cups

Thus, Clifford need 3.75 cups of flour, 2.5 cups of sugar and  1.25 cups of butter to make the cake.
