The number of hours for which the cost is the same would be 5 hours.

The cost of renting a snowboard for 5 number of hours would be same as that point i.e. $5

By costs, what do you mean?

Costs are really the monetary value of purchases made for use by a company or other accounting entity of supplies, service, labor, products, equipment, and other items.

The cost of renting a snowboard from the first company is $5 per hour + $50 deposit = $5x + $50.

The cost of renting a snowboard from the second company is $10 per hour + $25 deposit = $10x + $25. To find the number of hours for which the cost is the same, we set the two costs equal to each other and solve for x:

$5x + $50 = $10x + $25

$5x - $10x = $25 - $50

$5x = $25 - $50

$5x = -$25

x = -5

As we will not take cost in negative so it would be 5

So, we can say that the cost is same at any point of time.

According to the graph, the system of equations x + 4y = 6 and y = 2 x -3 has one solution that is (2,1)

In math the term called graph is defined as a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.

Here we know that the following equation are known:

=> x + 4y = 6

=> y = 2x - 3

And here we need to find the number of solution for the equations.

Here we have to plot the equation on the graph then we get the graph like the following.

Approximately 95.45% of the area under the standard normal distribution lies within two standard deviations of the mean.

The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. This means that 68.27% of the area under the standard normal distribution lies within 1 standard deviation of the mean, and 95.45% of the area under the standard normal distribution lies within 2 standard deviations of the mean.

This is because the standard deviation is a measure of the spread of the data; the larger the standard deviation, the more spread out the data is.

The length of the arc of the given circle with radius 10 cm and an angle of 2.5 radians subtended by an arc of a circle is equal to 25 cm.

Let 'y' represents the length of the arc of the given circle.

Radius 'r' of the given circle is equal to 10 cm

Angle 'α'  subtended by an arc of a circle is equal to 2.5 radians.

length of the arc = Angle subtended by an arc × Radius of the circle

⇒ y = rα

⇒ y = 10 × 2.5

⇒ y = 25 cm

Therefore, the length of the arc of a circle for the given radius 10cm and subtended angle 2.5 radians is equal to 25 cm.

The model with the highest revenue is model D

From the question, we have the following parameters that can be used in our computation:

Time to manufacture (mins) (t)         15             18         13              20     17

% Of monitors sold  (s)                  75%          73%      84%        95%   81%

Cost per monitor (c)                     $175         $188     $145     $198     $170

The factor works 9 hours for 7 days

So, the total duration per unit time is

D = 9 hours * 7/t

D = 63/t

Convert t to hours

D = 63 * 60/t

D = 3780/t

The total revenue is then calculated as

R = c * D * s

So, we have

Model A = 175 * 3780/15 * 75% = 33075

Model B = 188 * 3780/18 * 73% = 28820

Model C = 145 * 3780/13 * 84% = 35444

Model D = 198 * 3780/20 * 95% = 35551

Model E = 170 * 3780/17 * 81% = 30569

The distance of the translation resulting from the composition of the two reflections Rk and Rh is equal to |1 + 2x|

To determine the distance of the translation resulting from the composition of two reflections Rk and Rh, we can calculate the difference in x-coordinates of the pre-image and image points.

Reflection Rk reflects points over the line x = 2,

So the x-coordinate of a point and its reflection would have a difference of 2 - x, where x is the x-coordinate of the original point.

Reflection Rh reflects points over the line x = -3,

So the x-coordinate of a point and its reflection would have a difference of -3 - x

When we compose the two reflections

The x-coordinate of a point and its image will have a difference of (2 - x) - (-3 - x)

Confidence interval will be between $831.57 and $1040.67.

To find a confidence interval for the population standard deviation, we can use the formula:

(sample standard deviation / square root of sample size) x t-multiplier

where t-multiplier is based on the degree of confidence and the sample size.

For a 98% confidence interval and a sample size of 9, the t-multiplier is 2.821 (from a t-table or a calculator with a t-distribution function).

So the confidence interval for the population standard deviation is:

(886 / sqrt(9)) x 2.821 = (886 / 3) x 2.821 = 295.33 x 2.821

                                                                  = 831.57 to 1040.67

Therefore, we can be 98% confident that the population standard deviation of the annual earnings of college students falls between $831.57 and $1040.67.

Answer: This problem can be represented by the equation y = mx + b, where y is the total charges, x is the number of days, m is the charge per day, and b is the flat fee.

To find the values of m and b, we can use the given data points to solve for the equation.

For x = 2, y = 8, so 8 = m * 2 + b

For x = 4, y = 13, so 13 = m * 4 + b

For x = 6, y = 18, so 18 = m * 6 + b

We can then use a system of equations to solve for m and b:

m * 2 + b = 8

m * 4 + b = 13

m * 6 + b = 18

Using substitution or elimination methods:

m = 2

b = 2

Therefore, the equation is: y = 2x + 2

This means that the flat fee is $2 and the charge per day is $2.

The angular momentum of the the ball is 4.16kgrad/sec

Angular momentum is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity. This means that the total angular momentum of a closed system remains constant. Angular momentum has both a direction and a magnitude, and both are conserved. It is measure d in kgrad/sec

angular momentum = mass × angular velocity

mass = 0.18kg

angular velocity = 5.2 rad/s

therefore angular momentum = 0.18× 5.2

Answer:

Step-by-step explanation:

A good way to estimate is to round to the nearest whole number or 10th and then multiply:

8.70 --> 9.00 (since 7 > 5 you round up to the nearest whole number, in this case 9)

then you multiply. A good way to do this in your head is doing:

split 42 into 2 numbers:
40, 2

then multiply by nine:

9 * 4 = 36 (9 * 40 = 360) added a zero since we multiplied by 40, its just easier to multiply by smaller numbers

9 * 2 = 18

then add the two numbers together:

360 + 18 = 378 Euros

The actual answer with a calculator is 365.4 Euros, so for an estimation its fairly close.

Another way you could solve it is to just round 8.70 --> 10 (rounding to the nearest 10th)

then:

10 * 42 = 420 (nice)

I don't recommend it since its way too off from the original value, but could be good for quick estimations.
