What is the solution set of inequality 5-|x+4|<=-3

Eric took 20 hours to do the job alone.

Step-by-step explanation:

Given :

The amount of work Joe alone can do per hour = 75/5 = 15 packages.

The amount of work Joe and Eric together do per hour = 75/4 = 18.75

The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75

The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.

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°.

Answer:

n = 6

Step-by-step explanation:

Two intersecting chords. The product of the parts of one chord is equal to the product of the parts of the other chord, that is

7(n + 4) = 5(n + 8) ← distribute parenthesis on both sides

7n + 28 = 5n + 40 ( subtract 5n from both sides )

2n + 28 = 40 ( subtract 28 from both sides )

2n = 12 ( divide both sides by 2 )

n = 6

PLEASE GIVE BRAINLYEST

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]

Thus, he ran 5 mph in tuesday

Answer:

11.413 Hours.

Step-by-step explanation:

Alicia can paint a house in 21 hours; Which means in 1 hour she can paint 1/24 of the house.

Nina can paint the same house in (21+4)  hours. Which means in 1 hour she can paint 1/25 of the house.

Together in 1 hour they can paint:  1/21 + 1/25 = 46/525 of the house.

Total Hours for painting the house together will be 525/46 = 11.413 Hours.

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%.

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).

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.

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]
