Step-by-step explanation:

As,

[tex] {7}^{3} \times {7}^{ - 5} [/tex]

[tex] = {7}^{3 - 5} [/tex]

[tex] = {7}^{ - 2} [/tex]

Answer:

c. (1/7^2) is the answer

Answer:

OOOOOOOOOOOOOOOOOOOOOOOOOOO OK BRO

Step-by-step explanation:

The students must make use of varying string lengths in his experiment in other to make string length the independent quantity.

In the first first scenario,

The number of swings made by each pendulum is the dependent variable, as it is the variable which is measured in the experiment. While ;

The different pendulum masses tested are the Independent variable as it is the variable which is manipulated in other to cause changes to the measured variable.

In other make the string length the independent quantity, the student will need to use strings of different length and not just a string of 27 cm in other to be used as the independent variable. This will enable manipulation of the independent quantity to other to cause changes to the measured variable.

Answer:

  -2 7/8

Step-by-step explanation:

The usual recommendation is to convert the mixed numbers to improper fractions before multiplying.

  [tex]-2\dfrac{5}{9}\times1\dfrac{1}{8}=-\dfrac{9\cdot2+5}{9}\times\dfrac{8\cdot1+1}{8}\\\\=-\dfrac{23\cdot9}{9\cdot8}=-\dfrac{23}{8}=\boxed{-2\dfrac{7}{8}}[/tex]

__

Note the factors of 9 cancel in the first expression on the last line, leaving -23/8.

Answer:

[tex]\frac{23}{8}=2\frac{7}{8}[/tex]

Step-by-step explanation:

[tex]-2\frac{5}{9}\times \:1\frac{1}{8}[/tex]

Step 1: Convert into an improper fraction

[tex]2\frac{5}{9}=\frac{2\times 9+5}{9}\\\\=\frac{23}{9}[/tex]

[tex]-\frac{23}{9}\times \:1\frac{1}{8}[/tex]

[tex]1\frac{1}{8}=\frac{1\times 8+1}{8}\\\\=\frac{9}{8}[/tex]

[tex]-\frac{23}{9}\times \frac{9}{8}[/tex]

Step 2: Cross-cancel 9

[tex]=-\frac{23}{8}[/tex]

Step 3: Convert to an improper fraction

[tex]\frac{23}{8}=2\frac{7}{8}\\\\2\frac{7}{8}[/tex]

Answer:

Natural Numbers are basically "counting numbers". If I ask you to start counting, you'll start at 1, then 2, then 3, and so on. It doesn't include 0 or any negative numbers because you wouldn't start from -10 when asked to count.

Answer:

-7 is negative so it cannot be a natural number, but it is an integer. An integer is a whole number, this means that it does not have any decimal places or fractions. However, a natural number must be a whole non-zero number and positive. This is because natural numbers are numbers found naturally in measurements or in counting. Additionally, all natural numbers are integers but not all integers are natural numbers. For example, -3 would be an integer, 9 would be an integer and a natural number, and 7.6 would be neither.

Answer:

2n+8

Step-by-step explanation:

"eight more than twice a number" so twice a number would be 2n because its 2×n (double/twice a number) and eight more would be +8

(7 + y) - 6 = 8

If you also need the correct number its 7

(7 + 7) - 6 = 8

Answer:

7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

Ok, so we know 42 is the number of points added up, and we know that she threw 6 darts all scoring the same. Now, all we have to do is figure out what number(for example x) multiplied by 6 equals 42. Or in the form of an equation:

6x = 42

Now, to finish the equation, all we have to do is divide:

6x/6 = 42/6

42/6 = 7

x = 7

Hi! I'm happy to help!

To first solve this, we need to know what is going on. In the order of operations, everything inside of the parenthesis happens first. Since 4 and m are being multiplied inside of the parenthesis, that would happen before being moved to the fifth power. Since m is unknown, we make everything inside of the parenthesis to the fifth power, and make sure they are multiplied together as they are inside of the parenthesis. (Everything inside of the parenthesis applies to the raising to the fifth power.)

[tex]4^{5}[/tex]·[tex]m^{5}[/tex]

From here, we can simplify [tex]4^{5}[/tex] to 1024.

1024·[tex]m^{5}[/tex]

We don't need the multiplication sign because it is a variable.

1024[tex]m^{5}[/tex]

Since we cannot simplify m, this is our most simplified form: 1024[tex]m^{5}[/tex]
