Answer:

Part B (solution): For 0.42... (with the two repeating forever), we need to break up the decimal into the part that does not repeat and the part that repeats.

For the part that does not repeat, pretend that the repeating part is not there (so you have 0.4). Then think about place value. The non-repeating part of this decimal (0.4) is 4 tenths, so write that as a fraction: 4/10.

For the part that repeats, pretend the part that does not repeat is not there (so you have 0.2....). Use the rule of 9s, which tells you to put the repeating part (2) over a nine for every place value that is repeating. In this case there is only one repeating place value (again, 2), so we have 2/9. However, since we skipped a place value (the 4 in our given problem), we need to multiply that place value (in this case 1/10) by 2/9, which is 2/90. Finally, we need to add that to 4/10. Make sure your answer is simplified. Click HERE for help on Question 1.

Part C (solution): For 0.42... (with the four AND two repeating forever), use the rule of 9s. The rule of 9s tells you to put the repeating part (42) over a nine for every place value that is repeating. In this case there is two repeating place values, so we have 42/99.

Part A - (work for √3): Approximate the value of √3 to the nearest tenth. 3 is between the perfect squares 1 and 4. So √3 is between 1 and 2. The distance from 1 to 3 is 2. The distance from 1 to 4 is 3. The ratio is 2/3, or about .7. So, √3 is about .7 bigger than 1. Click HERE for help on Question 3.

Part A - (work for √5): Approximate the value of √5 to the nearest tenth. 5 is between the perfect squares 4 and 9. So √5 is between 2 and 3. The distance from 4 to 5 is 1. The distance from 4 to 9 is 5. The ratio is 1/5, or .2. So, √5 is about .2 bigger than 2. Click HERE for help on Question 3.

Part A - (work for 2√5): Approximate the value of 2√5 to the nearest tenth. 5 is between the perfect squares 4 and 9. So √5 is between 2 and 3. The distance from 4 to 5 is 1. The distance from 4 to 9 is 5. The ratio is 1/5, or .2. So, √5 is about .2 bigger than 2. Now multiply that value by 2. Click HERE for help on Question 3.

The fraction representation of 0.¯42 in simplest form is 14/33.

To express the repeating decimal 0.¯42 as a fraction in simplest form, we can use a mathematical technique.

Let's represent the repeating decimal as x = 0.¯42.

To remove the decimal part, we can multiply both sides of the equation by 100 (to move the decimal point two places to the right):

100x = 42.¯42.

Next, we subtract the original equation from the one multiplied by 100 to eliminate the repeating part:

100x - x = 42.¯42 - 0.¯42.

Simplifying both sides gives:

99x = 42.

Now, we can divide both sides of the equation by 99 to isolate x:

x = 42 / 99.

To simplify the fraction 42/99, we can find the greatest common divisor (GCD) of 42 and 99 and divide both the numerator and the denominator by it.

The GCD of 42 and 99 is 3:

42 = 3 x 14,

99 = 3 x 33.

Dividing both sides by 3 gives:

42 / 99 = (3 x 14) / (3 x 33) = 14 / 33.

Therefore, the fraction representation of 0.¯42 in simplest form is 14/33.

Answer:

16/52, or 4/13.

Step-by-step explanation:

First, since we know that the question is asking for the probability of a club or a jack, we know that we have to add the two probabilities. The first probability is that of picking a club, which is 13/52. The probability of picking a jack (be sure not to overlap; don't double count the jack of clubs) is 3/52. Adding these two gives us 13/52+3/52=16/52, which simplifies to 4/13.

Box plots, or box-and-whisker plots, show data distribution through five main points: minimum, Q1, median, Q3, and maximum. A wider box indicates greater variability within the middle 50% of the data. To compare box plots, assess the spreads, medians, and potential outliers.

A box plot, also known as a box-and-whisker plot, is a graphical representation of a data set that shows the distribution through five main data points: minimum value, first quartile (Q1), median, third quartile (Q3), and maximum value.

To construct a box plot, you typically start with a number line that has been properly scaled. Using a ruler for this purpose ensures accuracy.

The box in a box plot represents the middle 50 percent of the data, spanning from Q1 to Q3.

The 'whiskers' of the plot stretch from the box to the minimum and maximum values, indicating the entire range of the dataset.

Comparing the spread of the middle 50 percent of the data involves looking at the width of the box: a wider box suggests a greater spread, meaning the data is more varied within the interquartile range (IQR).

If you are using a graphing calculator, you can enter the data into a list and then select the box plot function to graphically display the data.

When comparing two or more box plots, look for differences in their central values (medians), spreads (IQRs), and potential outliers (which lie beyond 1.5 times the IQR from the quartiles).

Answer: The height of the rocket after 9 seconds is 2068.1 meters.

The height of the rocket when it initially launched is 269 meters.

Step-by-step explanation:

Given, NASA launches a rocket at [tex]t=0[/tex] seconds.

Its height, in meters above sea-level, in terms of time is given by [tex]h=-4.9t^2+244t+269.[/tex]

To find, the height of the rocket after 9 seconds put t=9, we get

[tex]h=-4.9(9)^2+244(9)+269\\\\=-4.9(81)+2196+269\\\\=-396.9+2465\\\\=2068.1[/tex]

Hence, the height of the rocket after 9 seconds is 2068.1 meters.

To find, the height of the rocket when it initially launched put t=0, we get

[tex]h=-4.9(0)^2+244(0)+269\\\\=0+0+269\\\\=269[/tex]

Hence, the height of the rocket when it initially launched is 269 meters.

Final answer:

The total amount Theo spent can be calculated on a calculator with the input: 8 × 4 + 3 × 3, which represents the cost of pencils plus the discounted cost of erasers.

Explanation:

To determine the total amount Theo spent, you need to calculate both the cost of the pencils and the cost of the erasers, taking into account the sale on erasers.

For pencils, Theo bought 8 packs at $4 each. For erasers, he bought 3 packs at a $2 discount from their regular price of $5 each, meaning each pack of erasers cost $5 - $2 = $3 per pack on sale.

The correct calculation on the calculator for the total amount spent would be the cost of pencils plus the cost of erasers: 8 packs × $4 per pack for pencils, plus 3 packs × $3 per pack for erasers on sale.

This can be entered into the calculator as 8 × 4 + 3 × 3.

Final answer:

The possible dimensions for a rectangular prism with a volume of 72 cubic meters are options B (3 m x 4 m x 6 m), D (9 m x 8 m x 1 m), and E (12 m x 2 m x 3 m), as their product of dimensions equals 72 cubic meters.

Explanation:

The question presents a schoolwork problem related to finding the possible dimensions of a rectangular prism with a given volume. According to the formula for volume, V = B x h, where V stands for volume, B is the area of the base, and h is the height. For a prism to have a volume of 72 cubic meters, the product of its dimensions (length x width x height) must equal 72.

For option A (2 m x 6 m x 7 m), the volume is 2 x 6 x 7 = 84 cubic meters, which is not equal to 72.

For option B (3 m x 4 m x 6 m), the volume is 3 x 4 x 6 = 72 cubic meters, which is correct.

For option C (3 m x 8 m x 4 m), the volume is 3 x 8 x 4 = 96 cubic meters, which is not equal to 72.

For option D (9 m x 8 m x 1 m), the volume is 9 x 8 x 1 = 72 cubic meters, which is also correct.

For option E (12 m x 2 m x 3 m), the volume is 12 x 2 x 3 = 72 cubic meters, which is another correct possibility.

Therefore, the possible dimensions for the rectangular prism with a volume of 72 cubic meters are represented by options B, D, and E.

The area of the given rectangle is 48 square units.

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

We have the graph from which we can write

width of rectangle = 8 unit

Length of rectangle= 6 unit

So, the area of rectangle

The correct answer of Resale value is :

The Ruiz family's laptop has the greater initial resale value.

The Ruiz family's laptop will have a higher resale value than the Sawyer family's laptop after 4 years.

The resale value of the Sawyer family's laptop decreases at a faster average rate than the resale value of the Ruiz family's laptop.

Based on the table, the Ruiz family's laptop has the greater initial resale value. They bought it for $640, while the Sawyer family bought their laptop for $620.

To compare the resale values of the two laptops after 4 years, we can evaluate the functions g(4) and A(4).

[tex]g(4) = 640 \times0.85^4 = 360.78[/tex]

[tex]A(4) = 620 \times 0.85^4 = 343.65[/tex]

Therefore, the Ruiz family's laptop will have a higher resale value than the Sawyer family's laptop after 4 years.

To compare the average rates of decrease of the resale values of the two laptops, we can calculate the following:

Average rate of decrease of the Ruiz family's laptop: (640 - 360.78) / 4 = 70.63

Average rate of decrease of the Sawyer family's laptop: (620 - 343.65) / 4 = 68.35

Conclusion:

The Ruiz family's laptop has the greater initial resale value.

The Ruiz family's laptop will have a higher resale value than the Sawyer family's laptop after 4 years.

The resale value of the Sawyer family's laptop decreases at a faster average rate than the resale value of the Ruiz family's laptop.

Answer:

5 hours per lawn

Step-by-step explanation:

15 hours divided by 3 lawns brings you to 5 hours per lawn.

The rate at which Lauren mows lawns is 5 hours per lawn, which means on average, it takes her 5 hours to mow one lawn.

The question is asking us to find out how long, on average, it takes Lauren to mow one lawn given that she can mow 3 lawns in 15 hours. This is a classic problem of rate, specifically a rate of work. The formula we use for rate is simply: Rate = Total Work / Total Time. Here, the total work would be the 3 lawns that she mowed, and the total time would be the 15 hours. So, we divide 15 (total hours) by 3 (total lawns) to get the rate of mowing:

Rate = 15 / 3 = 5 hours per lawn.

This means that, on average, it takes Lauren 5 hours to mow a single lawn.

The probability of randomly selecting two good bulbs is equal to 0.665.

So, we have a set of 32 bulbs, such that 26 are good and 6 are burned.

The probability of randomly selecting one good bulb is equal to the quotient between the number of good bulbs and the total number of bulbs.

It gives:

P = 26/32

Now, for the next bulb, the probability is computed in the same way, but now there are 25 good bulbs and 31 in total, so the probability is:

P' = 25/31
