Yes, 2.86 × 10⁸ is written in the scientific notation. it can be also expressed as expanded form :

Answer:286 000000

Step-by-step explanation:Scientific notation can be used to represent very large or very small numbers. A number written in scientific notation will have a non-zero digit to the left of the decimal point, multiplied by a power

ten , with an exponent corresponding to the number of places the decimal will move.

Answer:

[tex] \frac{6}{7} [/tex]

Step-by-step explanation:

[tex] \frac{5}{7} + \frac{1}{7} [/tex]

[tex] = \frac{6}{7} [/tex]

The dimension of a room is the length and width of the room.

From the question, we have:

[tex]L \to[/tex] Number of feet

(a) An expression for the length of the room in yards

In standard unit of conversion

[tex]1ft = \frac{1}{3} yd[/tex]

Multiply both sides by L:

[tex]L \times 1ft = L \times \frac{1}{3} yd[/tex]

[tex]L\ ft = \frac{L}{3} yd[/tex]

Hence, the length of the room in yard is L/3

(b) An expression for the length of the room in unit of 3ft

In (a), we have:

[tex]L \to[/tex] Number of feet

To calculate the length in units of 3 feet, we simply multiply L by 3

[tex]Unit = 3 \times L[/tex]

[tex]Unit = 3L[/tex]

An expression for the length of the room in unit of 3ft is 3L

(c) How many times longer the room is, than 3ft.

In (b), we have:

[tex]Unit = 3L[/tex]

The number of times (n) the room is longer than 3 ft is:

[tex]n = Unit \div 3[/tex]

[tex]n = 3L \div 3[/tex]

[tex]n = L[/tex]

The room is longer than 3 feet, in L times

Answer:

what question?...........

Step-by-step explanation:

7.)

13 - 24 / (8 - 2) × 1³

brackets first

13 - 24 / (6) × 1³

exponents next

13 - 24 / 6 × 1

dot operations (division, multiplications) next

13 - 24 / 6 × 1 = 13 - 24×1/6 = 13 - 24/6 = 13 - 4

dash operations (adding, subtracting) last

13 - 4 = 9

8.)

-81/9×4 + 8²

no brackets, so exponents first

-81/9×4 + 64

dot operations next (often best is going left to right, but the sequence actually does not matter; e.g. -81/9×4 = -81×4/9).

-81/9×4 + 64 = -9×4 + 64 = -36 + 64

dash operations last (again, sequence does not matter, if you handle all signs correctly, but in case of doubt just go left to right).

-36 + 64 = 28

No the larger the number the steeper the slope. 1 would be a steeper slope than a number less than 1.

Answer:

3 > -7

Step-by-step explanation:

-9 < 21

/-3   /-3

------------

3 < -7

Now, whenever you divide or multiply by a negative, you will change the inequality sign.

So, 3 < -7 becomes 3 > -7

Answer:

3 > -7

Step-by-step explanation:

-9/ -3 = 3

21/ -3 = -7

3 = -7

3 > -7

Answer:

Step-by-step explanation:

8/15

The fraction representing the number of apples is 8/15 thus, the numerator will be 8.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and the lower word is called the denominator.

As per the given apple lot,

The total number of fruits = 20

The total number of apples = 8

Thus, the fraction will be 8/20 where the numerator will be 8.

Hence "The fraction representing the number of apples is 8/15 thus, the numerator will be 8".

Answer:

The number of chirps per minute is 72

Step-by-step explanation:

Here, using the formula given, we want to find the number N representing the number of chirps per minute.

To get this, we shall simply substitute the value of 58 for T in the equation;

Thus;

58 = 50 + (N-40)/4

58 -50 = (N-40)/4

8 = (N-40)/4

4 * 8 = N -40

32 = N -40

N = 40 + 32

N = 72

The percentage can be written as a function of the number of years, that is:

[tex]p(x) = 33 - \frac{x}{2}[/tex]
