Step-by-step explanation:

Since when Fanta put 2 dollars in her account her brother put 5 dollars in his account, then

The ratio between them is

Fanta: brother

2 : 5

If Fanta has 40 dollars in her account, then by using the ratio method we can find the amount in her brother's account

Fanta: brother

2 : 5

40. : x

By using the cross multiplication

Divide both sides by 2 to find x

Her brother will have 100 dollars when she has 40 dollars

By using the tape diagram, add Fanta by 2 and her brother by 5

Fanta: 2 4 6 8. 10. 12. 14 16 18. 20. 22 24. 26. 28. 30

Brother: 5 10. 15. 20. 25. 30. 35. 40. 45. 50. 55. 60. 65. 70. 75

Fanta: 32. 34. 36. 38. 40

Brother: 80. 85. 90 95. 100

Another ratio could be any number multiply by 2 and 5 (I will multiply them by 30 to get a new ratio)

Fanta: 60

Brother: 150

The coordinates of the restaurant would be (-5, 3).

After leaving the movie theater and driving 5 km west and 3 km north to a restaurant, the coordinates of the restaurant are (5,-3).

The restaurant is 5 km west of the movie theater and 3 km north of the same. Thus, to get the coordinates of the restaurant, you can add the east-west distance to the x-coordinate of the starting point (movie theater), and the north-south distance to the y-coordinate of the starting point.

Using a Cartesian coordinate system, you can choose the point of origin (0,0) to represent the movie theater, and eastward and northward as positive x and y directions respectively. Then the coordinates of the restaurant would be (x,y), where:

x = (starting point's x-coordinate) + (distance travelled eastward)

y = (starting point's y-coordinate) + (distance travelled northward)

In this case, the restaurant is 5 km west of the movie theater, which is a distance travelled westward. Thus, the eastward distance travelled would be -5 km, since eastward direction is positive and westward is negative. Similarly, the restaurant is 3 km north of the movie theater, which is a distance travelled northward.

Therefore, the northward distance travelled would be +3 km, since northward direction is positive. Now we can substitute these values into the formula:

x = (starting point's x-coordinate) + (distance travelled eastward) = 0 - 5 = -5

y = (starting point's y-coordinate) + (distance travelled northward) = 0 + 3 = 3

Thus, the coordinates of the restaurant would be (-5, 3).

Step-by-step explanation:

Julie scores in the 85th percentile on the practice test for the GRE and scores in the 86th percentile on the actual GRE test. The practice test can be said to be 'accurate'.

A practice test is an informal examination that is taken as preparation for the actual examination. The practice test is not exactly the same as of actual test and you would not see any of the same questions of the practice test on the actual test but practice test questions cover the same distribution of the content of the actual test and are at a similar level of difficulty as the actual test.

For this reason, Julie scored in the 86th percentile in her actual GRE test after taking a practice test for GRE in which she scored in the 85th percentile.  Almost the same percentile of marks as the actual GRE test makes the practice test accurate.

Combining both cases, we find that the solution to the absolute value inequality is n ≤ -5.5 or n ≥ 4.5.

The absolute value inequality for the given sentence is |2n - (-1)| ≥ 10. This can be simplified as |2n + 1| ≥ 10.

To solve the inequality, we consider two cases:

Case 1: (2n + 1) ≥ 0

In this case, the inequality becomes 2n + 1 ≥ 10. Solving for n, we subtract 1 from both sides: 2n ≥ 9. Dividing both sides by 2 gives n ≥ 4.5.

Case 2: (2n + 1) < 0

In this case, we consider the absolute value of a negative number, which is equal to the positive opposite of that number.

Thus, the inequality becomes -(2n + 1) ≥ 10. Solving for n, we multiply both sides by -1 and reverse the inequality sign: 2n + 1 ≤ -10. Subtracting 1 from both sides, we get 2n ≤ -11. Dividing both sides by 2 gives n ≤ -5.5.

Combining both cases, we find that the solution to the absolute value inequality is n ≤ -5.5 or n ≥ 4.5.

Answer:

There are 10 cards in the stack, and 5 of them are odd (1, 3, 5, 7, and 9). There are 3 cards (1, 2, and 3) that are less than 4. Since we are replacing the first card before selecting the second, the outcomes are independent and we can multiply the probabilities of each event.

The probability of selecting an odd card on the first draw is 5/10, or 1/2.

The probability of selecting a card less than 4 on the second draw is 3/10, since there are 3 cards that meet this condition out of a total of 10.

Therefore, the probability of selecting an odd card on the first draw and a card less than 4 on the second draw is:

(1/2) x (3/10) = 3/20

So the probability of selecting an odd card on the first draw and a card less than 4 on the second draw is 3/20.

Step-by-step explanation:

Answer:

3/20.

Step-by-step explanation:

To find the probability of two independent events happening together, we multiply their individual probabilities. The probability of the first card being an odd number is 5/10, because there are 5 odd numbers out of 10 cards. The probability of the second card being less than 4 is 3/10, because there are 3 cards (1, 2, and 3) that are less than 4 out of 10 cards. Therefore, the probability of the first card being an odd number and the second card being less than 4 is:

5/10 x 3/10 = 15/100

We can simplify this fraction by dividing both the numerator and denominator by 5:

15/100 = 3/20

So, the final answer is 3/20.

Received message. To find the probability of two independent events happening together, we multiply their individual probabilities. The probability of the first card being an odd number is 5/10, because there are 5 odd numbers out of 10 cards. The probability of the second card being less than 4 is 3/10, because there are 3 cards (1, 2, and 3) that are less than 4 out of 10 cards. Therefore, the probability of the first card being an odd number and the second card being less than 4 is: 5/10 x 3/10 = 15/100 We can simplify this fraction by dividing both the numerator and denominator by 5: 15/100 = 3/20 So, the final answer is 3/20.

we can use the information given about its growth rate and the height after 4.5 years:So, it took 7 years from the time Vlad moved in until the tree was 357 centimeters tall.

Height increase per year = 26 centimeters
Years since Vlad moved in = 4.5 years
Height after 4.5 years = 292 centimeters
To calculate the initial height of the tree, we can multiply the growth rate by the number of years and add it to the starting height:
Initial height = Height after 4.5 years - (Height increase per year x Years since Vlad moved in)
Initial height = 292 - (26 x 4.5)
Initial height = 168 centimeters
Therefore, the tree was 168 centimeters tall when Vlad moved into the house.
To find out how many years passed from the time Vlad moved in until the tree was 357 centimeters tall, we can use the same formula and solve for the number of years:
Height increase per year = 26 centimeters
Initial height = 168 centimeters
Final height = 357 centimeters
To calculate the number of years, we can rearrange the formula as follows:
Years = (Final height - Initial height) / Height increase per year
Years = (357 - 168) / 26
Years = 6.04 years (rounded to two decimal places)
Therefore, it took approximately 6 years and 1 month for the tree to grow from 168 centimeters to 357 centimeters tall.
To determine the height of the oak tree when Vlad moved into the house, we can use the given information. The tree grows by 26 centimeters each year, and it was 292 centimeters tall after 4.5 years.
First, let's find the total growth during the 4.5 years:
26 cm/year * 4.5 years = 117 cm
Now, subtract the total growth from the current height to find the initial height:
292 cm - 117 cm = 175 cm
So, the oak tree was 175 centimeters tall when Vlad moved into the house.
To find out how many years passed until the tree was 357 centimeters tall, we can use the growth rate again:
First, find the difference in height between the target height (357 cm) and the initial height (175 cm):
357 cm - 175 cm = 182 cm
Now, divide the difference in height by the growth rate to find the number of years:
182 cm / 26 cm/year = 7 years
