The answer to your question is: 387.5 times distance from earth to the sun than distance from the earth to the moon

Step-by-step explanation:

Data

distance from earth to the sun = 9.3 x 10⁷ miles

distance from the earth to the moon = 2.4 x 10⁵ miles

distance ES to EM

Then we need to divide

 distance from earth to the sun / distance from the earth to the moon

9.3 x 10⁷ miles / 2.4 x 10⁵ miles

= 387.5 times is greater.

The distance from Earth to the Sun is about 387.5 times greater than the distance from Earth to the Moon. This is calculated by dividing the distance from Earth to the Sun by the distance from Earth to the Moon.

To determine how many times greater the distance from Earth to the Sun is than the distance from Earth to the Moon, we need to divide the distance from Earth to the Sun by the distance from Earth to the Moon. So, we have 9.3 × 107 miles (distance to the Sun) divided by 2.4 × 105 miles (distance to the Moon).

When you perform this calculation, you get a value of approximately 387.5. Therefore, the distance from Earth to the Sun is about 387.5 times greater than the distance from Earth to the Moon.

Answer:

Length = 128.3

Step-by-step explanation:

The 3 sides of a regular triangle are the same, the 2 sides that are in terms of x are equal:

5x + 40 = 8x - 13

40 + 13 = 8x - 5x

53 = 3x

17.7 = x

The length of a side = 5(17.7) + 40 = 128.3

In the equation, x represents the number of balloons. We say that 25 cents per balloon becomes 0.25x.

Jimmy also purchased a chocolate cake. This is the PLUS sign in the equation.

The total for everything purchased is $35.

Balloons x at 25 cents each = 0.25x plus a chocolate cake for $10 together equals $35.

On solving the equation -(6x+7)+8=19, we get value of x = -3.

To solve the equation -(6x+7)+8=19, we will first simplify each side of the equation and then solve for x. Here's how to do it step-by-step:

Distribute the negative sign across the parenthesis: -6x - 7 + 8 = 19.

Combine like terms on the left side: -6x + 1 = 19.

Subtract 1 from both sides: -6x = 18.

Divide both sides by -6 to find the value of x: x = -3.

Answer:

Step-by-step explanation:

z = a + bi

the complex conjugate is : Z = a-bi

so : Z-z =  (a-bi) - ( a + bi ) = a-bi -a -bi

Z-z = -2bi ...is a pure imaginary number (the statement is true)

The statement is true, Z-z is a pure imaginary number = -2bi.

What is conjugate complex?

A conjugate of a complex number is another complex number which has the same real part as the original complex number and the imaginary part has the same magnitude but opposite sign.

Here, given that, z = a+ib,

Let, Z be the complex conjugate of z, then, Z=a-ib

Now, Z-z = (a-ib)-(a+ib)

Part 2) m∠DCB=65°

Part 3) m∠CDB=90°

Part 4) m∠ACD=25°

Part 5) m∠ADC=90°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle DBC

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

In the right triangle ABC

m∠A+m∠B+m∠C=180° ----> equation A

we have

m∠A=65° ----> given problem

m∠C=90° ----> given problem

Substitute the given values in the equation A and solve for m∠B

65°+m∠B+90°=180°

m∠B+155°=180°

m∠B=180°-155°

m∠B=25°

Remember that the measure of Angle B is equal to say the measure of angle DBC

so

m∠B=m∠DBC

therefore

m∠DBC=25°

step 2

Find the measure of angle DCB and angle CDB

In the right triangle DBC

The sum of the interior angles of a triangle must be equal to 180 degrees

m∠DBC+m∠DCB+m∠CDB=180°

we have

m∠DBC=25°

m∠CDB=90° ----> is a right angle (CD is the height to AB)

substitute the values and solve for m∠DCB

25°+m∠DCB+90°=180°

m∠DCB+115°=180°

m∠DCB=180°-115°=65°

step 3

Find the measure of angle ACD

we know that

m∠ACD+m∠DCB=90° -----> by complementary angles

we have

m∠DCB=65°

substitute the value

m∠ACD+65°=90°

m∠ACD=90°-65°=25°

step 4

Find the measure of angle ADC

m∠ADC=90° ----> is a right angle (CD is the height to AB)

Final answer:

When Mike increased the size of his truck tires from the original P215/60R16 to the larger P235/70R16 without recalibrating his speedometer, the actual speed he was going on the new tires when his speedometer showed 60 mph was approximately 54.2 mph.

Explanation:

When Mike increased the size of his truck tires without recalibrating his speedometer, his speedometer reading would be inaccurate. To determine how fast he is going on the new tires when his speedometer shows 60 mph, we can use the concept of tire revolutions per mile.

The original tire size, P215/60R16, has a diameter of approximately 25.7 inches, while the larger tire size, P235/70R16, has a diameter of approximately 29.0 inches. The new tires cover a greater distance in one revolution compared to the original tires.

To calculate the actual speed, we can use the equation:

Actual Speed = Speedometer Reading * (Original Tire Diameter / New Tire Diameter)

Substituting the given values:

60 mph * (25.7 inches / 29.0 inches)

By simplifying this calculation, the actual speed is approximately 54.2 mph. Therefore, the correct answer is A. 54.2 mph.

Mike is actually traveling approximately 64.4 mph. Hence the correct option is c.

Calculate the difference in tire circumference:

Original circumference: 2 * π * radius = 2 * π * (215 mm / 25.4 mm/inch) * (60 + 30%) = 79.3 inches (assuming 30% aspect ratio)

New circumference: 2 * π * (235 mm / 25.4 mm/inch) * (70 + 30%) = 85.1 inches

Difference: 85.1 inches - 79.3 inches = 5.8 inches

Calculate the percentage increase in circumference:

(5.8 inches / 79.3 inches) * 100% = 7.3%

Apply the percentage increase to the speedometer reading:

Actual speed = Speedometer reading * (1 + % increase)

Actual speed = 60 mph * (1 + 7.3%) = 60 mph * 1.073

Actual speed ≈ 64.4 mph

Therefore, when the speedometer shows 60 mph, Mike is actually traveling approximately 64.4 mph. Hence the correct option is c.

Judy Clark will pay back $7,993.03 on January 20 for her loan of $7,800 at a 6.5% interest rate, with the interest being calculated for 140 days.

To calculate the amount Judy Clark will repay for a loan of $7,800 borrowed from Reel Bank at an ordinary interest rate of 6.5%, we need to determine the amount of interest accumulated by the loan from September 2 to January 20. This involves calculating the time period for the loan, applying the ordinary interest formula, and then adding the interest to the principal amount to find the total repayment amount.

We first calculate the number of days between September 2 and January 20. Without knowing the year of the loan, we can use an approximate count and consider a non-leap year for this example, which would be 140 days (30 days for September after the 2nd, 31 for October, 30 for November, 31 for December, and 18 for January).

Using the formula I = PRT, where P is the principal ($7,800), R is the annual interest rate (0.065), and T is the time in years (140/365), we can calculate the interest:

I = 7,800 × 0.065 × (140/365) = $193.03 (rounded to two decimal places).

To find the total repayment amount, we add the interest to the principal: $7,800 + $193.03 = $7,993.03.

Therefore, Judy Clark will pay back $7,993.03 on January 20.

3y=x+5

y=(x+5)/3

y= (1/3)*x + (5/3)

The general equation of y is:

y=mx+b

where:

slope=m

b= y intercept

so, slope is (1/3) and y intercept is (5/3)

and x intercept=0, when you star to graphic you can see that the only option for have y=(5/3) is necessary that the value of x=0. Or:

y intercept= (1/3)*x +(5/3) =(5/3)

(5/3)-(5/3)=(1/3)x

0=(1/3)*x

0/(1/3)=x

x=0.

Answer:

y = 3x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (2, 2) ← 2 points on the line

m = [tex]\frac{2+4}{2-0}[/tex] = [tex]\frac{6}{2}[/tex] = 3

Note the line crosses the y- axis at (0, - 4) ⇒ c = - 4

y = 3x - 4 ← equation of line

Explanation:

A "common denominator" is the least common multiple (LCM) of the denominators of the rational expressions involved. As such it can be found as the product of the unique factors of those denominators, each to its highest power.

For example, the common denominator for fractions with denominators of 20 and 25 will be 100. It can be found by considering the factors ...

  20 = 2² × 5

  25 = 5²

The unique factors here are 2 and 5, each with a highest power of 2. The product of these unique factors to their highest powers is ...

  2²·5² = 4·25 = 100.

___

Using this method of finding the LCM, it is essential that we know the factors of the numbers.

The LCM can also be found as the product of the numbers, divided by their greatest common factor (GCF). For this method, too, you need to know factors of the numbers involved--or, at least, the greatest common factor.

For the above example numbers, the GCF is 5, so their LCM is ...

  20·25/5 = 500/5 = 100

Factors can help you find a common denominator by revealing common multiples. By multiplying the denominators of the fractions together, you can often find a common multiple that can be used as a common denominator. Simplify the resulting fraction by canceling out any common factors.

Finding a common denominator involves identifying a common multiple of the denominators of the fractions you are working with.

Answer:

Probability of winning on one try : 1.16060875e-8

Step-by-step explanation:

For the first first 4 numbers.

Probability is 1/46 for the first number. Since the numbers are different, and it doesnt matter the order, the second number has a probability now of 1/45, the third has a probability of 1/44 and the last one a probability of 1/43.

Since the probability is dependan of the results of hitting the other number the probability of the first for numbers is the multiple of the 4 probabilities.

So it is 1/46 * 1/45 * 1/44 * 1/43 = 1 / 3916440

And that number is then multiplied by the probabilty of hitting the last number. 1/22

So the final probability is :

The probability of winning the jackpot on one try is 2.78 * 10^-7

Step-by-step explanation:

There are 46 balls in total  (46-1)+1 = 46 . (b-a)+1 is the formula for number of elements between a and b included.

We need to find the number of combinations possible of 4 balls ( as order doesn't matter - 1234 is the sames as 2341) . So the number of possible combinations of 4 balls taken from 1 - 46  is given by

C= n!/(r!(n-r)!) where n is the number of possible balls = 46 and r the size of combination = 4 and ! is factorial ( ex 3! = 3*2*1) This gives for this case

C= n!/(r!(n-r)!) = 46!/(4!(46-4)!)= 163,185 combinations.

But as there is a fifth ball with (22-1)+1   = 22 posible options each combination must be multiplied by 22( for example 1234 22 is one but also 1234 10 is other)

163,185*22= 3,590,070  possibilities.

The probability of winning is 1 in  3,590,070  possibilities. or

p = 1/ 3,590,070= 2.78 * 10^-7

Answer with Step-by-step explanation:

The exponential growth function is given by

[tex]N(t)=N_oe^{mt}[/tex]

where

[tex]N(t)[/tex] is the population of the bacteria at any time 't'

[tex]N_o[/tex] is the population of the bacteria at any time 't = 0'

'm' is a constant and 't' is time after 7.00 a.m in hours

Assuming we start our measurement at 7.00 a.m as reference time  t = 0

Thus we get[tex]N(0)=N_oe^{m\times 0}\\\\12=N_o[/tex]

Now since it is given after 5 hours the population becomes 14 mg thus from the above relation we get

[tex]12\times e^{m\times 5}=14\\\\e^{5m}=\frac{14}{12}\\\\m=\frac{1}{5}\cdot ln(\frac{14}{12})\\\\m=0.031[/tex]

Thus the population of bacteria at any time 't' is given by

[tex]N(t)=12e^{0.031t}[/tex]

Part a)

Population of bacteria after another 5 hours equals the population after 10 hours from start

[tex]N(10)=12e^{0.031\times 10}=16.361mg[/tex]

Part b)

Population of bacteria at 7:00 p.m is mass after 12 hours

[tex]N(1)=12e^{0.031\times 12}=17.41mg[/tex]

Part c)

Population of bacteria at 8:00 p.m is mass after 1 hour

[tex]N(1)=12e^{0.031\times 1}=12.3378mg[/tex]

Part d)

Differentiating the relation of population with respect to time we get

[tex]N'(t)=\frac{d(12\cdot e^{0.031t})}{dt}\\\\N'(t)=12\times 0.031=0.372e^{0.031t}[/tex]

Thus we can see that the percentage increase varies with time initially the percentage increase is 37.2% but this percentage increase increases with increase in time

Part 4)

Since there are 24 hours in 1 day thus the percentage increase in the population is

[tex]\frac{N(24)-N_o}{N_o}\times 100\\\\=\frac{25.25-12}{12}\times 100=110.42[/tex]

Thus there is an increase of 110.42% in the population each day.
