The approximate surface area of Arizona is calculated as 19.4% of Alaska's surface area, which is 588,000 square miles. By converting the percentage to a decimal and multiplying, we find that Arizona's surface area is approximately 114,072 square miles.

The question asks us to find the approximate surface area of the state of Arizona if it is 19.4% of the surface area of Alaska. To find this, we can use the known surface area of Alaska, which is approximately 588,000 square miles.

Here are the steps to calculate the surface area of Arizona:

So, the approximate surface area of the state of Arizona is 114,072 square miles.

The approximate surface area of the state of Arizona is 114,072 square miles, calculated as 19.4% of Alaska's surface area of 588,000 square miles.

To find the surface area of Arizona, we utilize the fact that it constitutes approximately 19.4% of Alaska's surface area.

This means that the surface area of Arizona is roughly 19.4% of the surface area of Alaska.

Given that the surface area of Alaska is approximately 588,000 square miles, we can calculate the surface area of Arizona by multiplying this value by 19.4%.

Mathematically, this can be expressed as:

[tex]\[ \text{Surface area of Arizona} = 0.194 \times \text{Surface area of Alaska} \][/tex]

Substituting the known value for the surface area of Alaska:

[tex]\[ \text{Surface area of Arizona} = 0.194 \times 588,000 \][/tex]

Calculating this yields:

[tex]\[ \text{Surface area of Arizona} \approx 0.194 \times 588,000 \][/tex]

[tex]\[ \text{Surface area of Arizona} \approx 114,072 \][/tex]

Therefore, the approximate surface area of the state of Arizona is 114,072 square miles, calculated as 19.4% of Alaska's surface area of 588,000 square miles.

This demonstrates the relative size of Arizona compared to Alaska.

Answer:15%

Step-by-step explanation:

Divide 20 by 4 then 3/4th are boys so take the answer and add it 3 times.

Given that 50% of the class are boys and 20% are blonde-haired, if there are three times as many blonde boys, the percentage of blonde boys in the class is 60%.

The question can be interpreted as looking for the percentage of boys with blonde hair in the entire class. We know that 50% of the class are boys and that there are three times as many boys that are blonde as the 20% that are generally blonde-haired. This means that 60% of the class are boys who have blonde hair.

We can calculate this by multiplying the total percent of blondes (20%) by 3, as we are told there are three times as many blonde boys. Hence, the percentage of blonde boys in the entire class is 60%.

Answer:

225

Step-by-step explanation:

We can model this question with:

9 = 0.04x

x represents "what number."

0.04x = 9.

Divide 0.04 from both sides

0.04x ÷ 0.04 = 9 ÷ 0.04

9 ÷ 0.04 = 225.

Therefore, 9 is 4% of 225.

Answer:

225

Step-by-step explanation:

Is means equals and of means multiply

9 = 4% * W

Change to decimal form

9 = .04 * W

Divide each side by .04

9/.04 = .04W/.04

225 = W

Final answer:

To find out how much Julia's movie ticket cost, we subtracted the cost of the popcorn ($7) from the total amount spent ($15) to get the movie ticket price of $8.

Explanation:

The student's question asks how much Julia's movie ticket cost if she spent a total of $15 on a movie ticket and popcorn combined, given that the popcorn cost $7. To solve this, we subtract the cost of the popcorn from the total amount spent.

Here's the calculation step by step:

Start with the total amount spent: $15.

Subtract the cost of the popcorn: $15 - $7.

The result gives us the cost of the movie ticket: $8.

Therefore, Julia's movie ticket cost $8.

EXPLANATION

The given line passes through (1,4) and (3,-4).

The slope of this line is calculated using the formula:

[tex]m =\frac{y_2-y_1}{x_2-x_1} [/tex]

We substitute the points into the slope formula to get:

[tex]m = \frac{ - 4 - 4}{3 - 1} [/tex]

[tex] \implies \: m = \frac{ - 8}{2} [/tex]

[tex]m = - 4[/tex]

We substitute the first point and slope into the point-slope formula

[tex]y-y_1=m(x-x_1)[/tex]

This implies that

[tex]y - 4 = - 4(x - 1)[/tex]

We expand to get

[tex]y - 4 = - 4x + 4[/tex]

[tex]y = - 4x + 2/4+ 4[/tex]

[tex]y = - 4x + 8[/tex]

From the given histogram, the mean of the distribution is 5. Therefore, option B is the correct answer.

In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).

From the given histogram, the frequency distribution is

Number      Frequency

     1                    1

     2                   2

     3                   3

     4                   1

     5                   1

     6                   2

     7                   3

     8                   1

     9                   1

Now, the mean is (1×1+2×2+3×3+4×1+5×1+6×2+7×3+8×1+9×1)/15

= (1+4+6+4+5+12+21+8+9)/15

= 70/15

= 4.67

≈ 5

Therefore, the mean is 5.

The mean of the data distribution is 6.3.

The mean of a data distribution can be calculated by summing all the values and dividing by the total number of values. Considering the data set 4, 5, 6, 6, 6, 7, 7, 7, 7, 8, the mean is:

Answer:

Step-by-step explanation:

To graph the function h(x) = 8|x+1| - 1, plot key points at (-3, 15), (-1, -1), and (1, 15). The graph exhibits vertical stretching due to the coefficient 8 and symmetry around the line x = -1.

To graph the function (h(x) = 8|x+1| - 1), follow these steps:

1. Identify Key Points:

  Determine critical points where the expression inside the absolute value becomes zero. Here, when (x = -1), (h(x) = -1). Additionally, consider points on either side of -1.

2. Plot Points:

  Plot these points on the coordinate plane: (-3, 15), (-1, -1), and (1, 15).

3. Determine Behavior:

  Understand that the absolute value function |x+1| ensures symmetry around the vertical line x = -1. The coefficient 8 stretches the graph vertically, and the constant -1 shifts it downward.

4. Connect Points:

  Draw a smooth curve connecting the points, considering the shape of the absolute value function.

5. Label Axes:

  Label the x-axis and y-axis appropriately.

The resulting graph represents the function [tex]\(h(x) = 8|x+1| - 1\)[/tex].

The simplified expression of (√12+6)(-√8-√2) is  -6(√6 + √2).

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

√12 x -√8 - √12 x √2 + 6 x -√8 - 6 x -√2

-√96 - √24 - 6√8 + 6√2

-√(16x6) - √(4x6) - 6√(4x2) + 6√2

-4√6 - 2√6 - 12√2 + 6√2

-6√6 - 6√2

Answer:

radius = 30 yd , cost of cement = $7065

Step-by-step explanation:

First we will find the area of the circular sectors. From that we can find the cost of cement and their radius.

The area of the playground is ...

playground area = (109 yd)^2 = 11,881 yd^2

Then the area of the skating rinks is:

rink area = playground area - remaining field

rink area = 11,881 yd^2 - 9,055 yd^2 = 2,826 yd^2

Then the cost of cement for the rink area is ...

(2826 yd^2)($2.50 yd^2) = $7065

The four quarter-circle skating rinks add to a total area of a full circle. That area is given by ...

A = πr^2

Put the values in the formula:

2826 = 3.14r^2

Divide both sides by 3.14

900 = r^2

By taking square root at both sides we get,

30 = r

Answer:

the solution set consists of {x < -2 ∪ x > 10/3}

Step-by-step explanation:

|3x - 2| > 8 is equivalent to the following set of inequalities:

1) 3x - 2 > 8

and

2) -(3x - 2) > 8

In case 1, above, add 2 to both sides, obtaining 3x > 10, or x > 10/3.

In case 2, above, carry out the indicated multiplication first:

-3x + 2 > 8.  Next, subtract 2 from both sides:  -3x > 6.

Next, divide both sides by -3, remembering to reverse the direction of the inequality sign:  x < -2.

Thus, the solution set consists of {x < -2 ∪ x > 10/3}

Answer:

x < -2 or x > 10/3

Step-by-step explanation:

3x - 2 > 8

3x > 10

-3x + 2 > 8

-3x > 6

x < -2

x < -2 or x > 10/3
