4275 divided by 28 showing the working out non calculator step by step

Answer:

Step-by-step explanation:

so the question is asking about the time from 1500 feet to 1100 feet.  How long did they fall, w/o a parachute.    aka   "freefall"   so,   at 1500 feet the jumper is really at time zero.   so, plug in to the formula

1100 = -16\(x^{2}\) +1500  

( x represents seconds so i'll change it to t so we know it's time )  

1100 = -16\(t^{2}\) + 1500

now we can solve for t  , to see how long the jumper falls

-400 = - 16\(t^{2}\)      ( subtracting 1500 from both sides of equation )

25 = \(t^{2}\)      ( dividing both sides by  -16 )

oh.. look at how nice that turns out.. :)

\(\sqrt{25}\) = t  ( take the square root on both sides )

5 = t    

the jumper fell for 5 seconds to get to 1100 feet  

The length of the arc is solved to get the proportion

= x / 12π = 130 / 360

this proves that the proportion would solve the arc length

length of arc is calculated using the formula given below

= (given angle)  / 360 x 2 π r

Where

x is length or arc

r is radius = 6 in

given angle = 130 degrees

then substituting into the formula

x = (given angle)  / 360 x 2 π r

x = 130  / 360 * 2 *  π * 6 in

x = 130  / 360 * 12π

dividing both sides by 12π

x / 12π = 130 / 360 (this equals the given proportion)

but solving for x

x = 13.61 in

4                                              A
5                                              7

The frequency is how many people have the shoe sizes. For example, 11 people have shoe size 3, and 7 people have shoe size 5. Since 30 people's shoe sizes were recorded, 30 - (11+7) will be the answer.

30 will be from the 30 people whos shoe sizes were recorded. The 11 will be from the people with shoe size 3, and the 7 will be from the people with shoe size 5. So, 30 - 18 = 12.

12 people have shoe size 4.

Answer:

Because it can make the problem harder

In maths, if there is a question that has a decimal for example like 33.33333333, then that will make the problem harder to perform, that's why, it's not necessary to take the exact answer for some problems. BUT, IF IT SAYS TO TAKE THE EXACT ANSWER, THEN YOU HAVE TO.

Answer:

(a) 3118=61*t

(b)  The amount of time the roller coaster is in motion is 51.11 seconds.

Step-by-step explanation:

Speed ​​is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, speed is associated with the change in position of a body over time and can be expressed as:

\(speed=\frac{distance}{time}\)

Then the distance traveled can be expressed as:

distance=speed*time

(a) If x represents the total time that the roller coaster is in motion for each ride, the average speed is 61 feet per second and the distance is 3118 feet then the expression to represent the situation is:

3118=61*x

(b)  To calculate the amount of time the roller coaster is moving, you simply need to solve the expression found in (a). Dividing 61 to both sides:

\(\frac{3118}{61} =\frac{61*x}{61}\)

51.11 seconds=x

The amount of time the roller coaster is in motion is 51.11 seconds.

The correct ratio to calculate MAPE is mad / (average demand).MAPE (Mean Absolute Percentage Error) is used to calculate the average percentage difference between actual and forecasted demand. It can be represented by the following formula:

MAPE = (1/n) * ∑(|actual demand - forecast demand| / actual demand) * 100

Where n represents the number of observations or time periods. In this case, MAD (Mean Absolute Deviation) is calculated by finding the absolute difference between actual demand and forecast demand. Then, the average of these absolute differences is taken to calculate the MAD. MAD is used as the denominator in the MAPE formula to calculate the average percentage error.

The other options listed are incorrect because:rsfe / mad: This ratio will not give the correct answer because the numerator (RSFE) is not used in the MAPE formula.rsef / (average demand): This ratio does not use MAD in the denominator and is therefore not a correct way to calculate MAPE.(average demand) / mad: This ratio is the reciprocal of the correct option (c), and therefore, will give the incorrect answer. Therefore, the correct ratio to calculate MAPE is mad / (average demand).

The number of possible combinations will depend on the size of the restaurant chain. However, we can always use the formula nCr to calculate the number of different possible ways to select r items from a set of n items.

To determine the number of different possible ways the general manager can select restaurants for the promotional program, we need to use the formula for combinations. Let's say there are n restaurants in the chain, and the manager needs to select r restaurants for the program. The formula for combinations is:
nCr = n! / r!(n-r)!
In this case, the manager needs to select a certain number of restaurants, so r is a fixed value. Let's assume the manager needs to select 5 restaurants for the program. Then the formula becomes:
nC5 = n! / 5!(n-5)!
We don't know the value of n, but we can calculate the number of possible combinations for different values of n. For example:
- If there are only 5 restaurants in the chain, then the manager has no choice but to select all of them. In this case, there is only one possible combination.
- If there are 10 restaurants in the chain, then the manager can select any 5 of them. Using the formula, we get:
nC5 = 10! / 5!(10-5)! = 252
So there are 252 different possible ways for the manager to select 5 restaurants from a chain of 10.
- If there are 20 restaurants in the chain, then the manager has even more choices. Using the formula, we get:
nC5 = 20! / 5!(20-5)! = 15,504
So there are 15,504 different possible ways for the manager to select 5 restaurants from a chain of 20.
In general, the number of possible combinations will depend on the size of the restaurant chain. However, we can always use the formula nCr to calculate the number of different possible ways to select r items from a set of n items.

Trevor and Kim will be situated 21 kilometers apart from each other at 1:30 PM. They will be separated by a distance of 21 km when the clock strikes 1:30 in the afternoon.

To determine at what time Trevor and Kim will be 21 km apart, we can set up a distance-time equation based on their relative speeds and distances.

Let's assume that t represents the time elapsed in hours since noon. At time t, Trevor would have traveled a distance of 8t km, while Kim would have traveled a distance of 6t km in the opposite direction.

Since they are running in opposite directions, the total distance between them is the sum of the distances they have traveled:

Total distance = 8t + 6t

We want to find the time when this total distance equals 21 km:

8t + 6t = 21

Combining like terms, we have:

14t = 21

To solve for t, we divide both sides of the equation by 14:

t = 21 / 14

Simplifying, we find:

t = 3 / 2

So, they will be 21 km apart after 3/2 hours, which is equivalent to 1 hour and 30 minutes.

Therefore, Trevor and Kim will be 21 km apart at 1:30 PM.

The required expression would be 12p - 33q + 104 which is equivalent form of 12(p + 5) − 11(3q + 4).

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

We have been given the expression:

12(p + 5) − 11(3q + 4)

Apply the distributive property of multiplication,

12p + 12 × 5 − 11 × 3q + 11 × 4

12p + 60 - 33q + 44

Rearrange the terms likewise and apply the arithmetic operation,

12p - 33q + 60  + 44

12p - 33q + 104

Therefore, required expression would be 12p - 33q + 104 which is equivalent form of 12(p + 5) − 11(3q + 4).

Step-by-step explanation:

Two rays form an angle. In this case, that angle is a 180-degree angle. It's also a line because the rays from point A are endless in either direction.

The slope-intercept form of the equation 5x + 3y = -9 is y = (-5/3)x - 3.

To rewrite the equation 5x + 3y = -9 in slope-intercept form, which is in the form y = mx + b, where m represents the slope and b represents the y-intercept, we need to solve for y.

Let's start by isolating y:

5x + 3y = -9

Subtract 5x from both sides:

3y = -5x - 9

Divide both sides by 3 to isolate y:

y = (-5/3)x - 3

Now, we have the equation in slope-intercept form. The slope of the line is -5/3, which means that for every unit increase in x, y decreases by 5/3 units. The y-intercept is -3, which means that the line intersects the y-axis at the point (0, -3).

Therefore, the slope-intercept form of the equation 5x + 3y = -9 is y = (-5/3)x - 3.

The semi-annual property tax bill is $2,987 and since it is semi-annual, he pays $2,987/2 = $1,493.5 each quarter.

So, each quarter he pays $1,493.5 + $334 = $1,827.5 for property taxes and homeowner's insurance.

And, each month he pays $1,827.5/3 = $609.17 for both property taxes and homeowner's insurance.

So, the total monthly payment he pays to North End Bank is $1,328 + $609.17 = $1,937.17.
