P, which is the principal invested is $7,000 whereas the T is 0.75

What is simple interest?

The simple interest on an investment such as that of Ryan, can be determined as the principal multiplied by the simple interest  rate and the time whose formula is as given below:

I=PRT

I=simple interest amount in dollars=unknown

P=principal investment=actual amount invested on simple interest basis=$7000

R=annual simple interest rate=8.3%

T=period of investment measured in years=9/12=0.75(9months divided by 12months in a year gives 0.75 years)

I=$7000*0.083*0.75

I=$435.75

Answer:

x = 52°

Step-by-step explanation:

Exterior Angle Theorem

The interior angles of a triangle sum to 180°.  Angles on a straight line sum to 180°.  Therefore, the exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.

⇒ x + 90° = 142°

⇒ x + 90° - 90° = 142° - 90°

⇒ x = 52°

Let us assume that,

→ x + y + 90° = 180°

Now the required value of y is,

→ y + 142° = 180°

→ y = 180° - 142°

→ [ y = 38° ]

Then the value of x will be,

→ x + 38° + 90° = 180°

→ x = 180° - 128°

→ [ x = 52° ]

Hence, the value of x is 52°.

a. A car travels 97.5 miles in 1.5 hours.

b. A car takes 2 hours to travel 130 miles.

c. Mai's equation matches the story because it is algebraic form of the formula of speed.

In this question, we have been given a car is going 65 miles per hour down the highway.

Part a.

A car is going 65 miles per hour.

This means, in 1 hour car traveled 65 miles.

Let car travels 'm' miles in 1.5 hours.

So, m = 1.5 × 65

m = 97.5 miles

Thus, a car travels 97.5 miles in 1.5 hours

Part b.

Suppose that it will take t hours to travel 130 miles.

We have been given 1 hour = 65 miles

So, we get an equation,

t = 130 / 65

t = 2 hours

This means, a car takes 2 hours to travel 130 miles.

Part c.

Mai wrote the equation y = 65x, with x representing the time traveled, in hours, and y representing the distance traveled, in miles.

We know that the formula of speed.

speed = distance / time

⇒ distance = speed × time

here, speed = 65 miles per hour

⇒ distance = 65 × time

Assuming distance = y  and time = x

y = 65x

This means,  Mai's equation matches the story.

Therefore, a. A car travels 97.5 miles in 1.5 hours.

b. A car takes 2 hours to travel 130 miles.

c. Mai's equation matches the story because it is algebraic form of the formula of speed.

The simplest method for locating a quadratic equation's roots is the quadratic formula. There are some quadratic equations that are difficult to factor, and in these cases we can quickly discover the roots by using the quadratic formula.

Gives the roots of a quadratic equation ax² + bx + c = 0.

x = [-b ± √(b² - 4ac)]/2a.

Now, We get

t= [-900 ± √((900)² - 4(-16)(-8825))]/2(-16)

t=[-900 ± √(810000-564800)]/-32

t=[-900 ± √(245200)]/-32

t=[-900 ± 495.17]/-32

First,

t=[-900 + 495.17]/-32

t=[-404.83]/-32

t=12.65

Second,

t=[-900 - 495.17]/-32

t=[-1395.17]/-32

t=43.59

Therefore, 12.65<t<43.59 will the projectile be above the ground at a height more than 9000 feet.

Using equation, the number of hours Ajay spent washing car and tutoring are 2 and 4 hours respectively.

Ajay is working two summer jobs working $8 per hour washing cars and $11 per hour tutoring.

Last week Ajay worked 2 more hours tutoring than hours washing cars and earned a total of $60.

The system of equation that could be used to determine the number of hours Ajay worked washing cars last week and the number of hours he worked tutoring last week can be calculated as follows:

let

x = number of hours washing cars

y = number of hours tutoring

Therefore,

y = 2 + x

Hence,

The slope of the line in the given diagram = rise/run = 1/2.

The slope of a line is determined as the ratio of the rise of the line to the run of the line.

The rise of a line = change in y

The run of a line = change in x.

The red line in the image attached below shows the rise of the line which is, 1 units.

The blue line represents the run, which is, 2 units.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The total amount earned in a week including the commission is $605 working for 40 hours.

The hourly rate is $15.125.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

The amount earned in a week = $350

Amount earned in commission = 3% of $8,500

= 3% of 8500

= 3/100 x 8500

= 3 x 85

= $255

The number of hours worked = 40 hours.

The hourly rate for the week:

= (350 + 255) / 40

= 605 / 40

= $15.125

Thus,

The hourly rate is $15.125.

By analyzing the geometric system, the measure of the angle RSP is equal to 49°.

In this problem we find a geometric system formed by two triangles, in which the line segment QR is parallel to the line segment PS. Then, we can obtain the following system of linear equations:

Intern alternate angles between parallel line segments

m ∠ QRP = m ∠ RPS

5 · y + 14 = 8 · y - 13

27 = 3 · y

y = 9

Internal angles of a triangles

m ∠ RPS + m ∠ PRS + m ∠ RSP = 180°

(8 · y - 13) + 3 · x + (2 · x + 1) = 180

8 · y + 5 · x - 12 = 180

8 · y = 180 + 12 - 5 · x

5 · x = 192 - 8 · y

x = (192 - 8 · y) / 5

x = (192 - 8 · 9) / 5

x = (192 - 72) / 5

x = 120 / 5

x = 24

Finally, the measure of the angle RSP is:

m ∠ RSP = 2 · x + 1

m ∠ RSP = 2 · 24 + 1

m ∠ RSP = 49

What is ratio?

Ratio determines how many times one number is bigger than the other number, provided both the numbers has the same unit.

The first part of the ratio is called antecedent and the second part of the ratio is called consequent

Here,

Number of red Skittles Rory has = 5

Number of yellow Skittles Rory has = 8

Number of purple Skittles Rory has = 6

Number of green Skittles Rory has = 4

Number of orange Skittles Rory has = 11

Total number of red and orange skittles = 5 + 11

                                                                   = 16

Total number of other skittles = 8 + 6 + 4

The coordinates of T are (13, -6) which s is the midpoint of rt r(-9,4) and s(2,-1).

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,

M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Assuming that S is the midpoint of the line segment RT, where point R's coordinates are (-9, 4) and S's coordinates are (2, -1).

We have to determine the coordinates of point T.

The midpoint is the average of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).

In this case, the midpoint is given by M = S(2, -1).

Let R(x₁, y₁) = R(-9, 4) and we will determine T(x₂, y₂).

2 = (-9 + x₂)/2

-9 + x₂ = 4

x₂ = 13

-1 = (4 + y₂)/2

4 + y₂ = -2

Using an exponential function, the sound intensity of a noise that is 130 dB is of I = 10 watts/m².

The sound level, in dB, of a sound of intensity given by I is given according to the following equation:

[tex]B = 10\log{\left(\frac{I}{I_0}\right)}[/tex]

In which [tex]I_0[/tex] is the smallest sound heard by the human ear, which is of [tex]I_0 =  10^{-12}[/tex] watts/meter.

Hence, for a sound of 130 db, the intensity I is found as follows:

[tex]130 = 10\log{\left(\frac{I}{10^{-12}}\right)}[/tex]

Isolating the logarithm, the equation is:

[tex]\log{\left(\frac{I}{10^{-12}}\right)} = 13[/tex]

The power of 10 and the logarithm are inverse functions, hence the power of 10 is applied to both sides of the equation to isolate the intensity creating the exponential function given as follows:

[tex]10^{\log{\left(\frac{I}{10^{-12}}\right)}} = 10^{13}[/tex]

[tex]\frac{l}{10^{-12}} = 10^{13}[/tex]

[tex]l = 10^{-12} \times 10^{13}[/tex]

Multiplying two terms with the same base and different exponents, we keep the base and add the exponents, hence the intensity is given as follows:

Answer:

Step-by-step explanation:

We have a quadtratic equation, that is, we have a function to the highest degree of x^2.

When solving this, we can either solve using the quadratic equation, or by solving for X which would be the easiest and quickest way to do it.

256 -16x^2=0

-16x^2=-256

x^2=16 (divide both sides by -16)

Which leaves x=4 as your answer.

To check this, we can simply input 4 back into the equation, and we will find that it does indeed equal 0.

To further visualize this, when we solve the equation for x, we are finding where the x value that intersects the x axis.  We are finding where x=0, or when it touches the ground.
