20k/20⁴=20⁹

20k=20⁴×20⁹=20¹³

k=20¹³/20=20¹²

Answer: k=20¹²

The value of k in the equation (20k)/(20⁴) = 20⁹ is k = 20¹¹.

To solve for the value of k in the equation (20k)/(20⁴) = 20⁹, we can follow these steps:

1. Simplify both sides of the equation:

(20k)/(20⁴) = 20⁹

So, (20k)/(20⁴) = (20⁴)²

2. Evaluate the exponent on the right side:

(20k)/(20⁴) = 20⁸

3. Multiply both sides by (20⁴) to eliminate the denominator on the left side:

[(20k)/(20⁴)] * (20⁴) = (20⁸) (20⁴)

Simplifying the left side:

20k = 20¹²

4. Divide both sides by 20 to solve for k:

(20k)/20 = (20¹²)/20

k = 20¹² / 20

5. Further simplify the right side:

k = 20¹¹

Therefore, the value of k in the equation (20k)/(20⁴) = 20⁹ is k = 20¹¹.

Answer:

  45°

Step-by-step explanation:

The sum of interior angles of the quadrilateral that has vertices at the center of the Earth, the two points of tangency, and the satellite is 360°. The angles at the points of tangency are 90°, so the angle at the satellite and the central angle are supplementary.

The arc has a measure of 180° -135° = 45°.

The point [tex](1,2)[/tex] is on the graph of the equation.

Explanation:

The equation is [tex]2x+3y=8[/tex]

We need to determine the point [tex](1,2)[/tex] is on the graph.

To determine the point [tex](1,2)[/tex] is on the graph, we need to substitute the point in the equation and find whether the LHS is equal to RHS.

Thus, substituting the point [tex](1,2)[/tex] in the equation [tex]2x+3y=8[/tex], we get,

[tex]2(1)+3(2)=8[/tex]

Multiplying the terms within the bracket, we have,

[tex]2+6=8[/tex]

Adding the LHS, we have,

[tex]8=8[/tex]

Thus, both sides of the equation are equal.

Hence, the point [tex](1,2)[/tex] is on the graph of the equation [tex]2x+3y=8[/tex]

This inequality can be simplified.

-m/-1 < 15/-1

m < -15

Best of Luck!

Answer:

m < -15

Step-by-step explanation:

Step 1:  Multiply both sides by -1

-m > 15

-m * -1 > 15 * -1

Since you multiply by a negative, you must flip the sign

-m * -1 > 15 * -1

m < -15

Answer:  m < -15

Answer:

x = 1 and y = - 4

Step-by-step explanation:

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line goes through.

Here the line passes through (1, - 4) with x- coordinate 1, thus

x = 1 ← equation of vertical line

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line goes through.

Here the line passes through (1, - 4) with y- coordinate - 4, thus

y = - 4 ← equation of horizontal line

Solution:

Given that,

Gavin ran 10 MPH during Monday's workout

50% slower during Tuesday's workout

Therefore,

Speed in tuesday = 50 % slower than monday

Which means,

Speed in tuesday = 10 - 50 % of 10

Solve the above

[tex]\text{ Speed in tuesday } = 10 - \frac{50}{100} \times 10\\\\\text{ Speed in tuesday } = 10 - 0.5 \times 10\\\\\text{ Speed in tuesday } = 10 - 5\\\\\text{ Speed in tuesday } = 5\\\\[/tex]

Answer:

a. y = 2.5

b. y = 3.5

c. y = 0.1036

d. y = 3

e. y = 150

Step-by-step explanation:

a. 10 ÷ 4 = 2.5

b. 17.5 ÷ 5 = 3.5

c. 1.036 ÷ 10 = 0.1036

d. 1.8 ÷ 0.6 = 3

e. 15 ÷ 0.1 = 150

For this case we must simplify the following expression:

Step-by-step explanation:

to get the answer you should add up the amount of chocolate chip and peanut butter cookies to get your total and then put it over the total amount of cookies you have

The probability of randomly choosing a chocolate chip or peanut butter cookie from the bag is 22/25 or 0.88 (rounded to two decimal places).

The probability of randomly choosing a chocolate chip or peanut butter cookie can be found by adding the probabilities of choosing a chocolate chip cookie and a peanut butter cookie.

The probability of choosing a chocolate chip cookie is the number of chocolate chip cookies in the bag divided by the total number of cookies:

P(chocolate chip) = 15/25 = 3/5

The probability of choosing a peanut butter cookie is the number of peanut butter cookies in the bag divided by the total number of cookies:

P(peanut butter) = 7/25

So, the probability of choosing a chocolate chip or peanut butter cookie is:

P(chocolate chip or peanut butter) = P(chocolate chip) + P(peanut butter)

P(chocolate chip or peanut butter) = 3/5 + 7/25

P(chocolate chip or peanut butter) = 15/25 + 7/25

P(chocolate chip or peanut butter) = 22/25

Therefore, the probability of randomly choosing a chocolate chip or peanut butter cookie from the bag is 22/25 or 0.88 (rounded to two decimal places).

Answer:

Step-by-step explanation:

Susan has $5000 invested at 6% and $15000 invested at 10%.

To solve the problem, let's use algebra to define the amount Susan has invested at each rate. Let the amount invested at 6% be represented by x, and consequently, the amount invested at 10% will be 3x, as it is three times the amount invested at 6%. The total interest from both investments is $1800 after one year.

The interest from the investment at 6% is 0.06x, and the interest from the investment at 10% is 0.10(3x), which is 0.30x. The equation representing the total interest is:

Total Interest = Interest from 6% + Interest from 10%

1800 = 0.06x + 0.30x

Combining like terms gives us:

1800 = 0.36x

Dividing both sides of the equation by 0.36 to solve for x:

x = 1800 / 0.36

x = $5000

This is the amount invested at 6%. The amount invested at 10% is 3 times that, so:

3x = 3 * $5000

3x = $15000

Therefore, Susan has $5000 invested at 6% and $15000 invested at 10%.

The distance from home to school will be 5 meters.

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

From the given image the distance between the home and school is followed by the square 3 meters from the home and the school is 4 meters making a right-angle triangle.

The minimum distance between the school and the home will be calculated as;-

D = √ ( 3² + 4² )

D = √ ( 25 )

D = 5 meters'

Therefore, the distance will be 5 meters.
