The average amount of rain fall is 9.61 inches

The average rainfall in Annette, Alaska is 0.31 inches per day. Over the course of an average September, the total amount of rain that falls is 9.3 inches.

To find out how much rain falls over the course of an average September, we need to know the number of days in September. Let's assume there are 30 days. Given that the average rainfall in Annette, Alaska is 0.31 inches per day, we can calculate the total rainfall by multiplying the average rainfall per day by the number of days in September: 0.31 inches/day * 30 days = 9.3 inches.

Answer:

[tex]x=-9[/tex]

[tex]y=4[/tex]

Step-by-step explanation:

[tex]3x+10y=13[/tex] ← Equation 1

[tex]4(-2y+x)-9x=13\\[/tex]

By simplifying the above equation we get,

[tex]-8y+=4x-9x=13[/tex] (Simplifying the brackets)

[tex]-8y-5x=13[/tex] (By subtracting [tex]-9x[/tex] from [tex]+4x[/tex]) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

[tex]15x+50y=65[/tex]

Equation 2 multiplied by 3 will give,

[tex]-24y-15x=39[/tex]

Add those together,

[tex]15x+50y-24y-15x=65+39[/tex]

[tex]26y=104[/tex] (After simplifying [tex]x[/tex] values)

Therefor [tex]y=4[/tex]

By substituting [tex]y=4[/tex] to Equation 1 we get,

[tex]3x+10*4=13[/tex][tex]3x+40=13\\3x=-27\\x=-9[/tex]

Therefor we can say,

[tex]x=-9[/tex]

[tex]y=4[/tex]

Solution

f(r) = 3.14[tex]r^{2}[/tex]

Now we have to find the area of the circle when the radius (r) = 4.

Plug in r = 4 in f(r) to get the area of the circle.

f(4) = 3.14[tex](4^{2} )[/tex]

f(4) = 3.14 * 4 * 4

f(4) = 3.14 *16

f(4) = 50.24

The answer is C. 50.24

Tom drank 2.25qt of the jug, in fraction form it would be 2 1/4

[tex]2x+4=16\\\\2x=12\\\\x=6[/tex]

The solution to the equation 2x + 4 = 16 is x = 6.

Given the equation in the question:

2x + 4 = 16

To solve the equation 2x + 4 = 16, first, isolate the variable term on one side by moving the constant term to the other side of the equation.

2x + 4 = 16

Subtract 4 from both sides of the equation:

2x + 4 - 4 = 16 - 4

2x = 16 - 4

Subtract 4 from 16:

2x = 12

Divide both sides of the equation by 2 to isolate the variable x:

2x/2 = 12/2

x = 12/2

x = 6

Therefore, the value of x is 6.

There are 13 rungs on the ladder :)

Answer:

23 rungs

Step-by-step explanation:

Let the number of rungs on the ladder be h and make the necessary adjustments based on this

Given that she is on the middle rung of a ladder this is equivalent to

= (h + 1)/2

She climbed up three rungs

= (h + 1)/2 + 3

moved down five rungs

= (h + 1)/2 + 3 - 5

and then climbed up 7 rungs

=  (h + 1)/2 + 3 - 5 + 7

Then she climbed up the remaining 6 rungs to the top of the ladder

(h + 1)/2 + 3 - 5 + 7 + 6 = h

(h + 1)/2 + 11 = h

h + 1 + 22 = 2h

2h - h = 23

h = 23

Using the concept of scale, we find that the distance between Cleveland and Cincinnati on the first map (1 cm to 10 km) is 40 cm, equivalent to 400 km in real-world distance. On the second map with a scale of 1 cm to 50 km, the equivalent distance is calculated to be 8 cm.

To calculate the distance between Cleveland and Cincinnati on the second map, we use the concept of scale. On the first map, the scale is 1 cm to 10 km, and the distance is represented as 40 cm. Scaling this to the real-world distance gives us 40 cm × 10 km/cm = 400 km between the two cities.

Now, let's apply the second map's scale of 1 cm to 50 km. To find the corresponding map distance, we set up a proportion: 10 km/cm (first map) / 50 km/cm (second map) = 40 cm (distance on the first map) / X cm (distance on the second map). Simplifying this, we find that X = 40 cm ×(10 km/cm) / (50 km/cm) = 40 cm × 1/5 = 8 cm.

Therefore, the distance between Cleveland and Cincinnati on the second map, which has a scale of 1 cm to 50 km, would be 8 cm.

The 2 angles are vertically opposite and that means they are equal.

Equation

(3x - 3) = [6(x - 10)]    

Solution

Remove the brackets.

3x - 3 = 6(x - 10)

3x - 3 = 6x - 60             Subtract 3x from both sides

- 3 = 6x - 60 - 3x           Combine like terms

-3 = 3x - 60                    Add 60 to both sides

-3 + 60 = 3x

57 = 3x                           Divide by 3

57 / 3 = 3x / 3

-6x=24

x=24/-6

x=-4

Hello there!

[tex]6-x=5x+30\\[/tex]

Explanation:

First you had to subtract by 6 from both sides of the equation.

[tex]6-x-6=5x+30-6[/tex]

Simplify

[tex]-x=5x+24[/tex]

Then you subtract by 5x from both sides of the equation.

[tex]-x-5x=5x+24-5x[/tex]

Simplify

[tex]-6x=24[/tex]

Divide by -6 from both sides of the equation.

[tex]\frac{-6x}{-6}=\frac{24}{-6}[/tex]

Simplify it should be the correct answer.

Answer:

38%

Step-by-step explanation:

Given that X,the hours per week the music student practice follow a normal distribution.

X:N(8,4)

We have to find the percentage of students who practice between 6 and 10 hours.

6<x<10 implies converting to z

We know z = (x-mean)/sigma = (x-8)/4

Hence 6<x<10 is equivalent to (6-8/4)<Z<(10-8/4)

= |z|<0.5

From std normal table we find this area equals = 0.1915+0.1915

=0.3830 = 0.38 (rounded off)

Hence required percentage = 0.38x100 = 38%

Final answer:

To determine the percentage of music students practicing between 6 to 10 hours, we convert these hours to z-scores and use the standard normal distribution table, which reveals that approximately 38.2% of students practice within this range.

Explanation:

To find the percentage of music students who practice between 6 to 10 hours per week, we can use the properties of the normal distribution. We first need to convert the range values to z-scores using the formula Z = (X - μ) / σ, where X is the value from the data set, μ is the mean, and σ is the standard deviation.

Converting 6 hours to a z-score:
Z = (6 - 8) / 4 = -0.5

Converting 10 hours to a z-score:
Z = (10 - 8) / 4 = 0.5

Now we use the standard normal distribution table to find the probability corresponding to these z-scores. The area under the curve between z-scores -0.5 and 0.5 gives us the desired percentage. Looking up the z-scores in the standard normal distribution table, we find that the area between these scores is approximately 38.2%. Thus, 38% is the closest option provided.

They should most definitely use meters. Meters are much bigger than centimeters as centimeters are 1/100th of a meter. Meaning, it will take 100 centimeters to get 1 meter. A soccer field is a large surface, and to get a simpler number, you should use meters.

In this Decimal Point Movement question, Moving the decimal five places to the right in mathematics is a shortcut for multiplication by 105 (one hundred thousand). This uses the principle of powers of ten.

In mathematics, moving the decimal five places to the right is actually a shortcut for multiplying by 105, or 100,000. This concept utilizes the patterns in powers of ten. For instance, for any given number, we can count the zeros in the power of ten and then move the decimal point that same number of places to the right.

Illustrating with an example, let's say we have the number 5.27. If we multiply it by 105, we move the decimal five places to the right to get 527000. This aligns with the multiplication principle: when we multiply by 10, 100, 1000, and so on, each time, we are essentially incrementing the decimal place to the right.

The value of f in the equation 6f − 12 = −4f + 6 is 1 4/5.

To answer the student's question, we need to solve the algebraic equation 6f − 12 = −4f + 6 for the unknown variable f. First, we want to get all terms with f on one side of the equation, and all constant terms on the other side. Thus, we'll add 4f to each side of the equation to eliminate -4f from the right side of the equation and get 6f + 4f = 6 + 12. This simplifies to 10f = 18, then we divide each side by 10, and we get f = 18/10 which reduces to f = 1 4/5 (Option C).

We should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Step-by-step explanation:

The blend should,

Cost = $5

Weigh = 6 pounds.

Lets take the weight of $6 coffee as [tex]x[/tex] pounds

And lets take the weight of $3 coffee as [tex]y[/tex] pounds.

Lets write an equation for the weight of the blend,

[tex]x+y=6[/tex] <---------- 1st equation.

[tex]\frac{6x+3y}{x+y} =5[/tex]

=[tex]6x+3y=5x+5y[/tex]

=[tex]x=2y[/tex] <---------- 2nd equation

We can substitute to x in 1st equation from 2nd equation,

⇒[tex]2y+y=6[/tex]

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

=[tex]3y=6[/tex]

=[tex]y=2[/tex]

We can substitute y value to 2nd equation to find x,

⇒[tex]x=2y[/tex]

=[tex]x=2*2[/tex]=[tex]x=4[/tex]

Therefore, we should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.
