Answer:

Step-by-step explanation:

If the coffee tastes like mud, it may be due to several reasons:

Overbrewing: If the coffee is brewed for too long or with too much coffee grounds, it can result in a bitter taste, and it may have a muddy texture.

Dirty equipment: Dirty coffee makers or dirty coffee cups can cause the coffee to taste like mud. Residual coffee oils, grounds, or bacteria can create an unpleasant taste.

Old coffee beans: Coffee beans that have been stored for too long or have expired can lose their flavor, making the coffee taste stale and muddy.

Poor quality water: The quality of water used to brew coffee can significantly affect its taste. Hard water, which has high mineral content, can give the coffee a muddy taste.

Poor quality coffee beans: Using low-quality coffee beans can result in a muddy taste. Coffee beans that are not roasted correctly or not freshly roasted can also create an unpleasant taste.

Ground coffee storage: If the ground coffee is not stored correctly, it can absorb moisture and other flavors in the air, resulting in a muddy taste.

To avoid a muddy taste in coffee, it is essential to use high-quality beans, grind the beans freshly, use clean equipment, and follow the proper brewing instructions. By doing so, one can enjoy a flavorful and satisfying cup of coffee.

Step-by-step explanation:

(a) If you face south and turn anti-clockwise to east, you'd have turned a right angle ( one 90° turn).

(b) If you turn clockwise from east to east again, you'd have completed a revolution or 360° (or 4 right angles)

(c) From west clockwise to south, you'd have turned 90° to north, another 90° to east and 90° to south making 3 right angles or 270°.

Answer: First Choice. 9r² + r -4

Step-by-step explanation:

Given information

Side 1 = 5r²+3

Side 2 = 4r²-6r+1

Side 3 = 7r-8

Formula for the perimeter of the triangle

Perimeter = Side 1 + Side 2 + Side 3

Substitute values into the formula

Perimeter = (5r² + 3) + (4r² - 6r + 1) + (7r - 8)

Simplify the expression

Perimeter = 5r² + 4r² + 7r - 6r + 3 + 1 - 8

Perimeter = 9r² + r + 4 - 8

Perimeter = [tex]\Large\boxed{9r^2+r-4}[/tex]

The cube root of 64 is 4, which is the value that, when multiplied by itself three times, equals 64.

The cube root of a number is the value that, when multiplied by itself three times, equals the original number. In the case of 64, the cube root is 4, because 4 multiplied by itself three times equals 64:

4 × 4 × 4 = 64

This can also be written using the cube root symbol (∛), as follows:

∛64 = 4

The cube root is an important mathematical operation used in a variety of fields, including engineering, physics, and finance. It is also used in everyday life, such as when calculating the dimensions of boxes or when determining the amount of material needed for a construction project.

It's important to note that the cube root is just one of several types of roots that can be taken of a number, including the square root (which is the value that, when multiplied by itself twice, equals the original number) and higher-order roots such as the fourth or fifth root.

Answer: To solve for A in the equation -BA + g² = MA, we can start by isolating the A variable on one side of the equation.

We can start by adding BA to both sides of the equation:

-BA + BA + g² = MA + BA

Simplifying the left side by cancelling the -BA and +BA terms:

g² = MA + BA

Next, we can factor out the A variable from the right side:

g² = A(M + B)

Finally, we can divide both sides by (M + B) to isolate the A variable:

g² / (M + B) = A

So the solution for A is:

A = g² / (M + B)

24 : 8

Step-by-step explanation:

24/4 is equal to 6

8/4 is equal to 2

Answer:

24:8

Step-by-step explanation:

The easiest way to do these kinds of problems is by doing some simple division.  Usually you only need to look at the first number, which in this case is 6, and see if any numbers can be divided by this number.  The first ratio is 24:8, and since the other first number can't be divisible by 6, we know the answer is 24:8

With the stated cooling rate of k = 0.012, it follows that the puddle of water would ice in the arctic cold front in roughly 97.8 minutes

The oscillation of a substance's components is measured by its temperature. When something is hot, it indicates that its components move relatively quickly on average. Despite having a high temperature, a substance's heat capacity is very low because it has a small number of light elements.

We can use the Newton's law of cooling formula to solve this problem.

[tex]T = R + ( To - R ) \times e ^{(-kt )}[/tex]

Let's assume that the initial temperature of the water is 55°F and the temperature of the surroundings is 5°F (due to the arctic cold front).

We are looking for the time it takes for the water to cool down to 32°F (the freezing point of water).

Therefore, we have:

T = 32°F

T0 = 55°F

R = 5°F

k = 0.012

Substituting these values into the formula, we get:

[tex]32 = 5 + (55 - 5) \times e^{(-0.012t)}[/tex]

Simplifying the equation, we get:

[tex]27 = 50 \times e^{(-0.012t)}[/tex]

Dividing both sides by 50, we get:

[tex]0.54 = e^{(-0.012t)}[/tex]

Taking the natural logarithm of both sides, we get:

ln(0.54) = -0.012t

Solving for t, we get:

t = ln(0.54) / (-0.012)

t ≈ 97.8 minutes

The value of millimeter in inches can be calculated by simply dividing the millimeter by 25.4 so 125 mm is 4.921 inches.

Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.

Converting from millimetres to inches

Calculation of Inches (dec) in Inches (frac) in Feet plus Inches ft mm to inches

* The value is rounded to the nearest 1/64 fraction for the inches fraction.

How to change metric units to inches

Inches are equal to 0.03937007874 millimetres in length:

1mm = (1/25.4)″ = 0.03937007874″

The distance d in millimetres (mm) divided by 25.4 gives the distance d in inches (′′):

d(″) = d(mm) / 25.4

Example of 20 mm converted to inches:

d(″) = 125mm / 25.4 = 4.92126″

How many millimetres are in one inch

0.03937 inches are equal to one millimetre:

Answer:

Plugging the numbers in, we get:

[tex]\sqrt{(3-(-2))^{2}+(-2-8)^{2}}[/tex]

Which we can simplify to:

[tex]\sqrt{(5)^{2}+(-10)^{2}}[/tex]

Squaring both numbers, we get:

Adding the numbers together, we get:

[tex]\sqrt{125}[/tex]

Which can be simplified to:

[tex]5\sqrt{5}[/tex] or 11.18033989, and rounding to the nearest tenth we'd get 11.2.

Therefore, the distance between the points (-2, 8) and (3, -2) is 11.2 units.

The price of each bagel sold when 312 bagels are sold and $280.80 earned  is $ 0.9.

One of the four basic mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups.

The number of bagels sold = 312

The total money earned by selling 312 bagels = $ 280 . 80

4(x + 23)

Is at least 18

≥ 18

Your inequality

4 (x + 23 ) ≥ 18

to solve, distribute

4x + 92 ≥ 18

subtract 92 from both sides

4x + 92 - 92 ≥ 18 - 92

simplify

4x ≥ -74

divide both sides by 4 to solve for x

The vertex form of a quadratic function is given by:

f(x) = a(x - h)^2 + k

where (h, k) is the vertex of the parabola.

Since the graph of f(x) = x^2 was translated 6 units to the left to create the graph of g, the vertex of g is at the point (h - 6, k).

The vertex of f(x) = x^2 is at (0, 0), so the vertex of g is at (-6, 0).

Since the vertex is at (-6, 0), the equation of g in vertex form is:

g(x) = a(x + 6)^2 + 0

We can find the value of "a" by using another point on the parabola. For example, if we know that g(-3) = 9, then we can substitute these values into the equation and solve for "a":

9 = a(-3 + 6)^2

9 = 9a

a = 1

So the equation of g in vertex form is:

g(x) = (x + 6)^2

There are 36 possible outcomes when rolling a pair of number cubes. To find the probability of rolling a sum greater than 10 on both rolls, we can start by listing all the outcomes where the sum of the first roll and second roll is greater than 10:

5 + 6 = 11

6 + 5 = 11

6 + 6 = 12

There are 3 ways to get a sum greater than 10. Since we are rolling the pair of number cubes twice, there are a total of 36 x 36 = 1,296 possible outcomes. The probability of rolling a sum greater than 10 on both rolls is therefore 3/1,296, which simplifies to 1/432.
