What is the length of a diagonal of a cube with a side length of 3 cm? O 18 cm 0 27 cm 182 cm OW38 cm​

Answers

Answer 1

Answer:

18 cm

Step-by-step explanation:

please mark this answer as brainliest

Answer 2

Answer:

18 cm

Step-by-step explanation:

The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.

Given: side x = 3 cm

Use the diagonal formula,

Diagonal of cube = 3–√x

Diagonal of cube = 3–√ × 3

We know that the value of √3 is 1.734

Therefore, the diagonal of a cube  = 1.734 (3)

Diagonal of cube = 5.20 cm

A collection of nickels and dimes is worth 25 dollars. There are twice as many nickels as dimes. How many of each are there? Use let statements and solve algebraically.
May I please get an explanation too?

Answers

There are 125 dimes and 250 nickels.

A dime is 0.1$ and a nickel is 0.05$. The total number of them should give 25$.
The number of nickels are twice the number of dimes. So lets call the number of dimes X, then the number of nickels should be 2X.

Putting it in a formula: 0.05(2X) + 0.1X = 25.

Then by solving we get:
0.1X + 0.1X = 25
0.2X = 25
X = 25/0.2 = 125

Step-by-step explanation:

divide by 7 on both sides

Answer:

n = 2

Step-by-step explanation:

7n is the same as 7 times value = 14.

You may find the value of n by simply dividing both sides by seven, in order to isolate the variable.

^ 14/7 = 7n/7

A fish was at the river-bed at a certain time. After 5 minutes, the water level of the river rose
up 2.4 cm and the water level of the river rose up again 3½cm after 4 minutes. The moment, the fish was at 14.6 cm from the river-bed and 162 cm below water level of the river.

Calculate the original height, in cm, of the water level of the river.​

Answers

Answer:

170.7 cm

Step-by-step explanation:

Let the original water level is x.

Use below equation to find its value:

x + 2.4 + 3 1/2 = 162 + 14.6x + 2.4 + 3.5 = 176.6x + 5.9 = 176.6x = 176.6 - 5.9x = 170.7 cm

Answer:

  x ∈ {-1/2, 1, 2-√3, 2+√3}

Step-by-step explanation:

The given zeros mean that one of the quadratic factors of the given polynomial is ...

  (x -2)^ -3 = x^2 -4x +1

When that is factored out (see first attachment), the remaining quadratic is ...

  2x^2 -x -1

This can be factored as ...

  = (2x +1)(x -1)

which has roots that make these factors zero: x = -1/2, x = 1.

So, all of the zeros of the given polynomial are ...

  -1/2, 1, 2-√3, 2+√3 . . . all zeros

A graphing calculator can often point to the zeros of the function quite nicely.

Additional comments

When p is a zero of a polynomial, (x-p) is a factor of it. The given zeros mean that factors are (x-2-√3) and (x-2+√3). The product of these factors is the difference of the squares (x-2)^2 and (√3)^2, so is (x -2)^2 -3.

Using the pattern for the square of a binomial, we see this is ...

  (x-2)^2 = x^2 -2·2x +2^2 = x^2 -4x +4

The product of the given factor is then 3 subtracted from this square. The given zeros mean there is a quadratic factor of ...

  (x-2-√3)(x-2+√3) = (x-2)^2 -3 = x^2 -4x +4 -3 = x^2 -4x +1
