Erica makes necklaces from beads. Each necklace consists of blue, white and green beads in the ratio of 6 : 4: 1 One necklace ne

Assoli18 [71]

Answer:

<u>For one Necklace you would need...</u>

24 blue beads.

16 white beads.

4 green beads.

Ratio: 24: 16: 4

Step-by-step explanation:

If you quadruple the amount of beads from the original amount (6 : 4: 1), the total beads for that necklace will be 44.

Step 1: 6 x 4 = 24 (amount of blue beads in necklace).

Step 2: 4 x 4 = 16 (amount of white beads in necklace).

Step 3: 1 x 4 = 4 (amount of green beads in necklace).

Now check to see if the total of all types of beads sum up to 44:

Step 4: 24 + 16 + 4 = 44

______________-

There is your answer:

You need 24 blue beads, 16 white beads, and 4 green beads to have a total sum of 44 beads in that one necklace.

Answer:

$\cos(D) = 0.2195$

Step-by-step explanation:

Given

The attached triangle

Required

$\cos(D)$

This is calculated as:

$\cos(D) = \frac{Adjacent}{Hypotenuse}$

So, we have:

$\cos(D) = \frac{1.8}{8.2}$

$\cos(D) = 0.2195$

Please show me step by step how to do this

Stels [109]

Answer:

The next three terms of the sequence are 17, 21 and 25.

The 300th term of the sequence is 1197.

Step-by-step explanation:

The statement describes an arithmetic progression, which is defined by following formula:

$p(n) = p_{1}+r\cdot (n-1)$ (1)

Where:

$p_{1}$ - First element of the sequence.

$r$ - Progression rate.

$n$ - Index of the n-th element of the sequence.

$p(n)$ - n-th element of the series.

If we know that $p_{1} = 1$ , $n = 2$ and $p(n) = 5$ , then the progression rate is:

$r = \frac{p(n)-p_{1}}{n-1}$

$r = 4$

The set of elements of the series are described by $p(n) = 1 + 4\cdot (n-1)$ .

Lastly, if we know that $n = 300$ , then the 300th term of the sequence is:

$p(n) = 1 + 4\cdot (n-1)$

$p(n) = 1197$

And the next three terms of the sequence are:

n = 5

$p(n) = 1 + 4\cdot (n-1)$

$p(n) = 17$

n = 6

$p(n) = 1 + 4\cdot (n-1)$

$p(n) = 21$

n = 7

$p(n) = 1 + 4\cdot (n-1)$

$p(n) = 25$

The next three terms of the sequence are 17, 21 and 25.

The 300th term of the sequence is 1197.
