Answer: 2439

I think what you want is, all the four digits numbers which can be formed with the help of the ten digits i.e. {0, 1, 2, 3, ……. … … , 9} which contains 0 at least once in it. Taking this way, to find all the required numbers, we may proceed as follows;

To form four digits numbers means to fill up four vacant places say X, X, X, X with the help of these ten digits. Since nothing has been said about repetition or non-repetition of the digits, so I take it that repetitions of digits are allowed so that all possible numbers come into consideration. Now;

1st vacant place can be filled up by 9 ways (as 0 can not come to this place otherwise number formed will be of three digits). Further,

2nd, 3rd and 4th vacant place each can be filled up by 10 ways (each)(as 0 may also come to these places).

Hence, total no. of numbers of four digits = 9 .10.10.10 = 9000.

Next the total no. of numbers of four digits without zero at any place = 9. 9. 9. 9 = 6561.

Therefore, required no. Of numbers of four digits having at least one zero = 9000 - 6561 = 2439.

Answer:

13.83 %

Step-by-step explanation:

13/94 = 13.829...

13.829 rounded to nearest hundredth = 13.83

The correct choice is:

The graph titled 'Hours of Sunlight and plant growth' showing 'hours of sunlight' from 0 to 17 in increments of 2 on the x-axis and 'growth in inches' from 0 to 12 in increments of 1 on the y-axis has points at (8, 1), (9, 2), (10, 3), (11, 3), (12, 5), (13, 6), (14, 7), (15, 9) and (16, 10).

(OR)

The scatter plot graph titled 'Hours of Sunlight and plant growth' is shown with 9 data points showing a positive relationship. The x-values of the data points extend from 8 to 16, and the y-values of the data points extend from 10 to 1.

From the given table, we have the following data points:

(8, 1), (9, 2), (10, 3), (11, 3), (12, 5), (13, 6), (14, 7), (15, 9), and (16, 10)

The correct choice shows that these data points are plotted on a scatter plot with the x-axis ranging from 0 to 17 (in increments of 2) and the y-axis ranging from 0 to 12 (in increments of 1).

The scatter plot shows a positive relationship between the two variables, which means that as the hours of sunlight increase, the growth of the plant also increases

Answer: 25 miles

Step-by-step explanation:

Answer:

The answer is 25.

Step-by-step explanation:

Since the scale shows 10 miles for every 2 inches, you can easily figure out that it is 5 miles per inch.

Now, it says two towns are 5 inches apart. With the previous information, you can either multiply 5 inches by 5 miles per inch or think deeper.

Thinking deeper: If there is 4 inches, that is 20 miles. Adding another inch doesn’t add another ten. It adds half of ten and half of ten in 5. 20+5=25

Answer:

Each Almond costs $1.5

Each Jelly bean costs $3.75

Step-by-step explanation:

Let Almonds be a

Let Jelly beans be j

- For the first case;

3$ of Almond + 2$ of Jelly beans = $12

[tex]{ \tt{3a + 2j = 12 - - - eqn(i)}}[/tex]

- For the second case;

5$ of Almond + 6$ of Jelly beans = $30

[tex]{ \tt{5a + 6j = 30 - - - eqn(ii)}}[/tex]

✍️ From equation (i), make 2j the subject;

[tex]{ \tt{2j = 12 - 3a - - - eqn(iii)}}[/tex]

✍️ Substitute 6j in eqn (ii) with 2j in eqn (iii)

[tex]{ \tt{5a + 6j = 30}} \: \: \: \: \: \: \\ \\ { \tt{5a + 3(2j) = 30}} \\ \\ { \tt{5a + 3(12 - 3a) = 30}} \\ \\ { \tt{5a + 36 - 9a = 30}} \\ \\ { \tt{ - 4a + 36 = 30}} \\ \\ { \tt{ - 4a = - 6 }} \\ \\ { \tt{a = 1.5}} \\ \\ { \colorbox{silver}{almond = 1.5 \: pounds}}[/tex]

From eqn(iii)

[tex]{ \tt{2j = 12 - 3a}} \\ \\ { \tt{2j = 12 - 3(1.5)}} \\ \\ { \tt{2j = 7.5}} \\ \\ { \tt{j = 3.75}} \\ \\ { \colorbox{silver}{jelly \: beans = 3.75}}[/tex]

One mile is equal to 1,760 yards. Therefore, two and one-half miles can be calculated as:

2.5 miles * 1,760 yards/mile = 4,400 yards

So, the answer is A) 4,400 yards.

Step-by-step explanation

For the first sum you nee to find the same coefficient or add or subtract a number

[tex]-x^3 -2x -7[/tex]

This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.

The next sum we have to simplify both numerals so we know if both sum’s answer are

[tex]-x^3 -2x -7-x^3 -2x -7[/tex]

After simplifying them,  both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same

Step-by-step explanation:

Answer:

Converting customary units of weight can be helpful in everyday life when you need to measure ingredients for cooking or baking. For example, if a recipe calls for 2 pounds of ground beef, but you only have a scale that measures in ounces, you will need to convert the measurement to ounces to make sure you use the correct amount of beef.

To convert pounds to ounces, you can use the conversion factor of 16 ounces per pound. So, to convert 2 pounds to ounces, you would multiply 2 by 16, which equals 32 ounces.

Another example is when you need to weigh yourself in kilograms, but your scale measures in pounds. To convert pounds to kilograms, you can use the conversion factor of 0.453592 kilograms per pound. So, if you weigh 150 pounds, you can convert that to kilograms by multiplying 150 by 0.453592, which equals 68.04 kilograms.

In general, knowing how to convert between customary units of weight can help you to make accurate measurements and better understand how much of a substance you are using or consuming.
