Answer:

= 624.26 m²

Step-by-step explanation:

The area of a circle is given by the formula;

A = πr² ; where r is the radius

Radius = 1/2 diameter

   = 3.14 × 14.1 ×14.1

   = 624.26 m²

Final answer:

To estimate the area of a circle with a diameter of 28.2m, calculate the radius (14.1m), then use the formula A = πr² with pi as 3.14 to get an area of approximately 624.33 m² after rounding to the nearest hundredth.

Explanation:

To estimate the area of a circle with a given diameter of 28.2m, we first need to calculate the radius, which would be half of the diameter. Thus, the radius (r) is 28.2m / 2 = 14.1m.

Next, we use the formula for the area of a circle, which is A = πr². Plugging in the numbers, we get A = (3.14)×(14.1m)².

Carrying out the multiplication, we have A = 3.14 × 198.81m² = 624.3254m². We round this result to the nearest hundredth to get 624.33 m² as the estimated area of the circle using 3.14 for pi.

Answer: 8/15

Step-by-step explanation:

There are 15 total combinations of characters and defense tools in this game. If you randomly choose your character and tool, the probability that you will be a magic user, a user of one of the five tools, is 1 out of 15 or 0.0667.

In this game scenario, the total number of different combinations that can occur when you randomly choose your character and tool is equal to the product of the number of choices for each. We have 3 choices for characters (elf, hobbit, human) and 5 choices for defense tools (magic, sword, shield, slingshot, umbrella). Therefore, the total different combinations are 3*5 = 15. The question asks for the probability that you'll be a magic user, irrespective of the character. Since magic is one of the 5 defense tools, then, there is 1 favorable outcome that we are considering.

The number of favorable outcomes by the total number of possible outcomes is known as the probability of an event. So, we have 1 favorable outcome and 15 total outcomes. Therefore, the probability is 1/15 or approximately 0.0667.

Answer:

3n³/5m²

Step-by-step explanation:

Given in the question an expression

3m^-2 / 5n^-3

we can separate them as

3 / 5  x m^-2 / n^-3

As we know the rule of negative exponents that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.

Here the negative exponents are -2 and -3

so, m^-2 =1 /m²

      n^-3 =1 /n³

3 / 5 x n³/ m²

rearranging

3n³/5m²

Answer:

the system has a unique solution

Step-by-step explanation:

Start with an equation of a line in standard form,

[tex] ax + by = c [/tex]

Solve it for y to put it into the slope-intercept form:

[tex] by = -ax + c [/tex]

[tex] y = -\dfrac{a}{b}x + \dfrac{c}{b} [/tex]

The slope is -a/b.

Now look at your system of equations. The slope of the first equation is -a/b = -2/3. The slope of the second equation is -a/b = -6/5.

You have a system of two linear equations with two lines with different slopes, so the lines must intersect at a single point.

Answer: the system has a unique solution

====================================================

Explanation:

The variable b is the placeholder for the original price, aka price before discount.

We discount by 25% meaning we don't pay that 25% but instead pay the remaining 75%

Therefore the expression 0.75*b represents the final price after the discount. We're told this price is $1.50 so that is how I'm getting the answer to be 1.50 = 0.75b

----------------------------

Extra info:

To solve this equation for b, you would divide both sides by 0.75 to undo the multiplication that is happening.

1.50 = 0.75b

1.50/0.75 = 0.75b/0.75 .... dividing both sides by 0.75

2.00 = b

b = 2.00

So the original price before discount was $2.00; note how 25% of this is 0.25*2.00 = 0.50 which is the amount we save and the amount we have left is 2.00 - 0.50 = 1.50 which is the proper price after discount we want.

There are "40 hours per week."     [unit rate means "how many of these for one of those"]

Notice how units cancel when we use the Multiplicative Identity (that is 1 -- multiply any value by 1 and it does not change):

    1  =   (40 hours)/(1 week) = (1 week)/(40 hours)        [choose the value needed to cancel units]

  120 hours

  (120 hours) * 1

  (120 hours) * (1 week)/(40 hours)

  (120/40) weeks                      [hours cancel, leaving only weeks[

     3 weeks

    5 weeks

   (5 weeks) * 1

   (5 weeks ) * (40 hours)/(1 week)

    (5*40) hours                    [note that weeks cancel]

     200 hours

Final answer:

The relationship between hours and weeks indicates a direct linear relationship, where each week is equivalent to 40 hours.

Explanation:

The relationship between the corresponding number of hours and weeks from the given sequences {0, 40, 80, 120, 160, 200, 240, 280, 320} for hours and {0, 1, 2, 3, 4, 5, 6, 7, 8} for weeks indicates a linear relationship. For every 40 hours, one week passes, which suggests that each week consists of 40 hours in this context. This can be expressed by the linear equation hours = 40 × weeks

Therefore, the required relationship is linear

Answer:

22

Step-by-step explanation:

Divide the area (in square units) by Pi (approximately 3.14159).

Example: 380.13/3.14 = 121.06

Then square the answer.

121.06 squared = 11.0

That answer is the radius, double that to get the diameter.

11.0 * 2 = 22

Final answer:

To calculate the diameter of a circle with an area of 380.13 m², solve for the radius using the formula r = √(A/π) and then double that value to find the diameter, resulting in a diameter of approximately 22.00 meters.

Explanation:

To find the diameter of a circle with a given area, we start with the formula for the area of a circle, which is A = πr², where A is the area, π (Pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. Given the area A = 380.13 m², we can solve for the radius r by rearranging the area formula to r = √(A/π) and then calculating the diameter D by doubling the radius (D = 2r).

Step 1: Calculate the radius.
r = √(A/π) = √(380.13 m² / 3.14159) ≈ 11.00m

Step 2: Calculate the diameter.
D = 2r = 2 × 11.00m = 22.00m

25x4=100%

1x4=4

To solve the problem we must know about Percentage.

25% of 4 is equal to 1.

A percentage is a way to describe a part of a whole. such as the fraction [tex]\dfrac{1}{4}[/tex] can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given information,

Let's assume that the number is x.

We know that when the percentage symbol is removed the number is divided by 100. so,

25% = [tex]\bold{\dfrac{25}{100}}[/tex]

Dividing the numerator 25 And the denominator by 25,

25% = [tex]\bold{\dfrac{1}{4}}[/tex]

Now, to get a percentage of any number simply multiply the number by the fraction(or decimal) form of the percentage value. So, here we will multiply the number 'x' to [tex]\bold{\frac{1}{4}}[/tex] (fraction form of 25%) to get 1.

[tex]x \times 25\% = 1\\x \times \dfrac{1}{4} = 1\\\\x = 4[/tex]

Hence, 25% of 4 is equal to 1.

3x + 4y = 8

4y = 8 - 3x

y = 2 - (3/4)x

So the slope of the given line is -(3/4).

Final answer:

The slope of the line represented by the equation 3x + 4y = 8 is -3/4. We found this by rearranging the equation into slope-intercept form, y = mx + b, and identifying the coefficient of x as the slope.

Explanation:

To find the slope of the line represented by the equation 3x + 4y = 8, we first need to rearrange the equation into the slope-intercept form, which is y = mx + b, where m represents the slope of the line, and b represents the y-intercept. Let's solve for y:

The slope-intercept form of the line is y = (-3/4)x + 2, so the slope is -3/4. This means for every increase of 1 on the horizontal axis (x), there is a decrease of 3/4 on the vertical axis (y).
