Answer:

Our required integers will be 9,11,19.

Step-by-step explanation:

Let three integers all less than 25 be x,y,z

Since we have given that

Range = 10

Mean = 13

These three integers will be

Since their range is 10 i.e.

And Mean = 13

Hello from MrBillDoesMath!

Answer: 6 * p^(3/2) * q^4

Discussion:

We are evaluating

sqrt { 36 * p^3 q^8 }

where "sqrt" indicates the square root and the ^ (as in q^8) means "raised to the power of:

The square root of the product is the product of the square roots. (Say that 5 time out loud quickly!). So the above equation becomes

sqrt { 36 * p^3 q^8 } =

sqrt( 36) * sqrt( p^3) * sqrt (q^8)

The square root of 36 is 6 as 6* 6 = 36 so the equation equals

6 * p ^ (3/2) * q^ (8/2)

Note that the square root of a number, for example, r, is the same as raising the number to the (1/2) power. That's where the (1/2) terms came from above.

But 8/2 = 4 so the equation simplifies to

6 * p^(3/2) * q^4

Thank you,

A certain radioactive isotope has leaked into a small stream. Three hundred days after the leak, 3% of the original amount of t

sesenic [268]

If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days

But, during the same summer, teachers stopped wearing high heels; each of them became 4% shorter. Copy and fill in the chart. Te

alexgriva [62]

Answer:

It is given that,

'When the teachers stopped wearing heels, they became 4% shorter'.

So, the relation becomes,

<em>Height without heels = Height with heels - 4% of height with heels</em>

Then, we have,

1. Ms. Mathey is 190 cm with heels.

So, Ms. Mathey = 190-4% of 190 = 190 - 7.6 = 182.4 cm without heels

2. Mrs. Meansy is 162.5 cm with heels.

So, Mrs. Meansy = 162.5-4% of 162.5 = 162.5 - 6.5 = 156 cm without heels

3. Ms. Cool is 140 cm with heels.

So, Ms. Cool = 140-4% of 140 = 140 - 5.6 = 134.4 cm without heels

Also, the relation can be written as,

<em>Height with heels = Height without heels + 4% of height without heels</em>

4. Miss Short is 155.1 cm without heels

So, Miss Short = 155.1+4% of 155.1 = 155.1+6.2 = 161.3 cm with heels

5. Miss Lora is 159.8 cm without heels

So, Miss Lora = 159.8+4% of 159.8 = 159.8+6.4 = 166.2 cm with heels

Thus, the final table is,

Height with Heels Height without Heels

Ms. Mathey 190 cm 182.4 cm

Mrs. Meansy 162.5 cm 156 cm

Ms. Cool 140 cm 134.4 cm

Miss Short 161.3 cm 155.1 cm

Miss Lora 166.2 cm 159.8 cm
