Answer:

Step-by-step explanation:

To get this right, we need to get the correct formula for the volume of a cube.

Imagine this:

What is the area of a square? Easy ! Length of the edge times itself. You can imagine what this means as the edge if the we have one line E move straight along an E-long line, the path it made is the square.

Similarly to the cube. Imagine what can be a volume of a cube with edge E that has something to do with the edge?

That's right. A square with edge Emove vertically straight in a E-long line. So the correct volume should be the area of the square times the length of its edge. But the area of the square is already the edge times itself

In formula, if a cube has volume V and edge length E, we have the equation.

V = E×E×E

Answer:

20

Step-by-step explanation:

since the sign is pointing to the "greater number"

any number over 13 is fine

The value of x can be 14, 15, .... and so on.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write  Olivia's Age ≤ 12. This is a real-world example of an inequality.

Given:

13< x

So, we have to choose the value which are greater than 13.

The value of x cannot be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.

Thus, the value of x can be satisfies by 14, 15, .... and so on.

The probability the letters will spell the word ENVELOPE is 1/6720 option (D) 1/6720 is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

If all the letters in the word ENVELOPE are randomly rearranged,

As we know, a permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

From the definition of the permutation and combination we can calculate the total number of arrangements:

E :: 3

N :: 1

V :: 1

L :: 1

O :: 1

P :: 1

The arrangement Letters:

E,L,N,O,P,V

Total Number of Letters:

8

Total Number of Unique Letters:

6

Total arrangements  = 8!/3!

Total arrangements  = 8×7×6×5×4

Arrangements  =  6720

Total number of outcomes = 6720

Number of favorable outcomes = 1

Probability = 1/6720

Thus, the probability the letters will spell the word ENVELOPE is 1/6720 option (D) 1/6720 is correct.

Answer:

6 + x = 9

Step-by-step explanation:

We know that x = 3, and that we need to add x (which equals 3) to 6.

So, all we need to do is add 6 + 3.

6 + x = 9

We know this because for the expression 6 + x, we replace x with it's given value, which is 3.

Answer:

The total cost for john's meal would be $66.84

Step-by-step explanation:

6.5% of 52.30 = 3.3995

52.30 plus 3.3995 = 55.6995

20% of 55.6995 = 11.14$

55.6995 + 11.14 = $66.84

Answer:

function 2 only

Step-by-step explanation:

The Function that have a slope have 1 is Function 1.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

From function 1, the slope is

Slope = (0-2)/ (1- 3)

Slope = (-2)/ (-2)

Slope = 1

Now, for function 2 the slope is

Slope = 2

and, for Function 3 the slope is

Slope = 0

and, For function 4 the slope is

Slope = 3/2

Thus, Slope of function 1 have slope 1.

x=-2, y= 1

Step-by-step explanation:

Given data

-2x+3y= 7 --------------1

5x+8y= -2--------------2

Multiply 1 by 5 and 2 by 2 and add

-2x+3y= 7   X 5

5x+8y= -2   X 2

-10x+15y= 35  

10x+16y= -4  

0x+31y= 31

31y= 31

y= 31/31

y= 1

put y= 1 in eqn 1

-2x+3y= 7

-2x+3(1)= 7

-2x+3=7

-2x= 7-3

-2x= 4
