Heather runs 3 miles in 28 minutes. At the same rate, how many miles would she run in 42 minutes?

This question does not require a diagram to be drawn, so based on the scale factor or ratio of 1 inch : 4 yards and since the actual width of the neighborhood park is 60 yards, the width of the drawing is 15 inches.

The scale factor is the ratio of a scale drawing or model to the actual dimension of the object.

The scale factor is also measured as the dimension of the new shape ÷ dimension of the original shape.

The Ratio of the scale drawing = 1 inch : 4 yards

The actual width of the park = 60 yards

The scaled-down width of the drawing = 15 inches (60/4).

Thus, we can conclude that the scale drawing's width that Darrell made was 15 inches.

0.2083335 is the Area of the triangle.

How do triangles work?

The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a single point.

                            180 degrees is the sum of the triangle's three angles. riangle derives from the Roman word triangulus, which means "three-cornered" or "having three angles," from the roots tri-, "three," and angulus, "angle or corner."

1 ft 1 in =  12 + 1 = 13 in

  the Area of the triangle = 1/2 * b * h

                                        = 1/2 *   1 * 0.416667

Answer:

First, find the total number of cups of liquid in the punch:

24 cups pineapple juice + 46 cups orange juice + 72 cups seltzer = 142 cups

Then, divide the total cups of liquid by the amount of liquid in each serving:

108 cups / 142 cups per serving = 0.76 servings

Therefore, approximately 0.76 servings can be made from 108 cups of punch.

Step-by-step explanation:

the ratio is 30/21600 = 3/2160 = 1/720

that means for every degree the hour hand moves, the second hand does 2 full rotations (2×360°).

h = s×30/21600 = s/720

FYI :

as there are 12 hours on a clock, every hour means 360/12 = 30° rotation for the hour hand.

so, for each hour the second hand moves 21600°.

that means 21600/360 = 60 full rotations.

that means one rotation of the second hand is 1 minute.

so, the second hand is truly a second hand (counting the seconds).

60 seconds in a minute (a full rotation by the second hand), that means each second corresponds to 360/60 = 6° rotation of the second hand.

The time it will take for Alex to earn enough money to purchase his shoes is given as follows:

13.6 weeks.

The time needed to obtain enough money to purchase the shoes is obtained applying the proportions in the context of the problem.

Alex saves $10 every 4 weeks. He earned an extra $12 for cleaning his neighbor’s garage, hence the amount he must save is of:

45.99 - 12 = $33.99.

Considering that he saves $10 each week, and he must save $33.99 to purchase the shoes, the number of periods of four weeks that he needs is of:

33.99/10 = 3.399 periods of four weeks.

As each period is composed by four weeks, the number of weeks that he needs to save enough money is obtained as follows:

Tο calculate the current thrοugh a 2.5 οhm resistοr cοnnected acrοss a 6.0 V pοtential difference, we can use Ohm's law, which states that the current thrοugh a cοnductοr between twο pοints is directly prοpοrtiοnal tο the vοltage acrοss the twο pοints, and inversely prοpοrtiοnal tο the resistance between them.

where V is the vοltage, I is the current, and R is the resistance.

We can rearrange this fοrmula tο sοlve fοr the current I:

The graph of the rational function y = f(x) is represented by the blue line on the graph above. The x-intercept is the point at which the function crosses the x-axis and is labeled (0, 0).

The vertical asymptote at x = 3 is the red line. The local approximation for the vertical asymptote at x = 3 is represented by the black line and is given by y = 568 - 332(x - 3). Similarly, the vertical asymptote at x = -2 is the purple line and the associated local approximation is given by y = -2(x + 2). Finally, the horizontal asymptote at y = 2 is the orange line.

To illustrate the graph, assume the function f(x) is the following: f(x) = (x + 2)(x - 3) / (x + 5). This function is a rational function, as it is the ratio of two polynomials, and it has the given constraints.

To graph the rational function, we begin by finding the x-intercept, which is (0, 0). Then, we look at the vertical asymptote. At x = 3, the local approximation is given by y = 568 - 332(x - 3). We solve the equation y = 568 - 332(x - 3) for x, and get x = 3, thus we mark this point on the graph as the vertical asymptote. We do the same for the vertical asymptote at x = -2 and mark this point on the graph. Finally, we draw the line for the horizontal asymptote at y = 2. This gives us the complete graph of the rational function y = f(x).

In conclusion, the graph of the rational function y = f(x) that displays the four constraints can be sketched and labeled as shown in the figure above.

We can conclude that the students did not have any time left to work on homework.

The duration of Mr. K's math class is 1 and 1/4 hours, or 5/4 hours.

We need to determine how much time is left for the kids to do their assignment after working on problems on the board for 55 minutes and 11/12 hours. To achieve this, we must take the time spent solving issues out of the overall class time:

Total class time = 5/4 hours

Time spent on working problems = 55 minutes + 11/12 hours

= (55/60) hours + (11/12) hours

= (11/12 + 55/60) hours

= (11/12 + 11/12) hours

= (22/12) hours

= (11/6) hours

Overall class time minus the amount of time spent solving problems equals the amount of time remaining for homework.

= 5/4 hours - 11/6 hours

= (15/12) hours - (22/12) hours

= (-7/12) hours

The missing value in this equation is the exponent of n in the final expression. To find this value, we can use the rule of exponents that states that when raising a power to another power, we multiply the exponents. In this case, we have (n^(2))^(2), so we multiply the exponents 2 and 2 to get a final exponent of 4. Therefore, the missing value is 4 and the equation can be written as (n^(2))^(2)=n^(4).

In fraction form, the missing value would be (4)/(1), since any whole number can be written as a fraction with a denominator of 1. So, the equation can also be written as (n^(2))^(2)=n^((4)/(1)).

The complete question is:

The solutions to the equation (w-2)^(2)-54=0 are w = 2, w = 9, and w = -6.

The equation (w-2)2 - 54 = 0 can be solved by factoring.

Let's start by writing the equation as: (w-2)(w-2) - 54 = 0

We can factor out (w-2) to get: (w-2)(w2 - 4w - 54) = 0

Now we can factor the second part of the equation, by splitting the middle term (4w) to get: (w-2)(w-9)(w+6) = 0

Now we have three equations, which we can solve separately:

w - 2 = 0 → w = 2

w - 9 = 0 → w = 9

w + 6 = 0 → w = -6

Therefore, the solutions to the equation (w-2)2 - 54 = 0 are w = 2, w = 9, and w = -6.

Answer:

To apply the first derivative test to the function f(x) = 2x^3 + 3x^2 - 12x + 5, we need to find its derivative:

f'(x) = 6x^2 + 6x - 12

Then, we need to find the critical points by solving for f'(x) = 0:

6x^2 + 6x - 12 = 0

Dividing both sides by 6, we get:

x^2 + x - 2 = 0

Factoring the left side, we get:

(x + 2)(x - 1) = 0

So the critical points are x = -2 and x = 1.

To determine the intervals where f(x) is increasing and decreasing, we need to evaluate f'(x) on each side of the critical points. We can use a sign chart to do this:

x     |  -2  |  1  |

------|-----|----|

f'(x) | -12 |  0 |

Since f'(x) is negative to the left of x = -2 and positive to the right of x = -2, the function is decreasing to the left of x = -2 and increasing to the right of x = -2. Since f'(x) changes sign at x = 1, there is a local minimum at x = 1.

Therefore, using the first derivative test, we can conclude that the function has a local minimum at x = 1.

a. The probability that x=10 in a Poisson distribution with µ = 7 is 0.0942.
b. The probability that x > 5 in a Poisson distribution with µ = 7 is 0.4790.

A discontinuous probability distribution is a Poisson distribution. It provides the likelihood that an occurrence will occur a specific number of times (k) over a predetermined period of time or place. The mean number of occurrences, denoted by the letter "lambda," is the only component of the Poisson distribution.

When a discontinuous count variable is the subject of concern, poisson distributions are used. Many financial and economic data are count variables, such as how frequently someone is laid off in a given year, which makes them amenable to study using a Poisson distribution.

One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division.

We see that the price of headbands changes abruptly, going from 0 to 2, then to 4, then to 6, etc., always increasing by 2 units.

The “add 8” rule applies to the price of T-shirts because each one costs $8.

In order to determine the cost of six headbands, we then perform the following calculations:

8 + 8 + 8 + 8 + 8 + 8 = 6 x 8 = $48

We see that we can easily multiply the required quantity of T-shirts by the cost per unit of T-shirts.

Therefore, the cost of the T-shirt is $48.
