Answer 16

36/2.25= 16 pieces of rope

Answer: 16

Step-by-step explanation:

To get the number of tape that can be cut from 2 1/ 4 , we simply divide 36 by 2 1/4

36 ÷ 2 1/4

but 2 1/4 = 9/4

36 ÷ 2 1/4 = 36 ÷9/4 = 36 × 4/9

=144 / 9

=16

Therefore, we can cut sixteen 2 1/4 m lengths of tape from 36m.

If two angles are complementary. One angle measures 22 degrees. And the other angle measures 2x degrees, what is the value of x?
levacccp [35]

Answer:

x=34

Step-by-step explanation:

34*2=68

68+22=90

A complementary angle adds up to 90 degrees.

17/9 15 divided 6 divided 30 divided and 3^3 from least to greatest
qaws [65]

I assume you mean: Order the following from least to greatest:

17/9, 15 divided by 6, 30, and 3^3

17/9 = 1 8/9

15/6 = 2 1/2

3^3 = 9

So it would be: 17/9, 15 divided by 6, 3^3, and 30

Make necessary adjustments if it was actually 6/30; the wording was confusing.

natita [175]

<em>Answer:</em>

<em>There would be 173,535 lionfish after 6 years.</em>

<em>Step-by-step explanation:</em>

<em>Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:</em>

<em></em>

<em>A)</em>

<em>8000 x 1.67 ^ n = f  </em>

<em>B)</em>

<em>8000 x 1.67 ^ 6 = X</em>

<em>8000 x 21.691961596369 = X</em>

<em>173,535.692770952 = X  </em>

<em>C)</em>

<em>(8000 - 1200 x 1 ^ n) x 1.67 ^ n = f</em>

<em>Therefore, there would be 173,535 lionfish after 6 years.</em>

In a normal distribution, what is the probability that a data value will fall below the 
Serga [27]

Answer:

A 99.96%

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is positive if the raw score is above the mean while the z score is negative if the raw score is below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma} \\\\where\ z=z-score,\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }

The probability can be gotten from the normal distribution table. Therefore from the normal table:

P(z < 3.37) = 0.9996 = 99.96%
