In a thunderstorm, the wind velocity in meters per second can be described by the function v(p) = 5.7 √998 - p, where p is the a

nataly862011 [7]

Answer:

923.1927 millibars

Step-by-step explanation:

The wind velocity is given by the function:

$v(p)=5.7\sqrt{(998-p}$

#We make p the subject of the formula:

$v(p)=5.7\sqrt{(998-p}\\\\v=5.7\sqrt{(998-p}\\\\\frac{v}{5.7}=\sqrt{(998-p}\\\\\frac{v^2}{5.7^2}=998-p\\\\p=998-\frac{v^2}{5.7^2}$

#Substitute the given values in the function above to solve for p;

$p=998-\frac{v^2}{5.7^2}\\\\=998-\frac{49.3^2}{5.7^2}\\\\=923.1927\ millibars$

Hence, the air pressure is 923.1927 millibars.

What is the estimate for the probability of selecting a red crayon OR a yellow crayon from the bag?

pogonyaev

Answer: It would be both because there is no number to it

Step-by-step explanation:

For example if there were 15 red crayons and 10 yellow ones it would be the red crayons because there is a bigger amount of them in the bag but because there is no number you have the same possibility of picking both.

Go step by step to reduce the radical of the equation given. (Figure the step for the box)

Rama09 [41]

$\sqrt{32} ~~ \begin{cases} 32=2\cdot 2\cdot 2\cdot 2\cdot 2\\ \qquad 2^4\cdot 2\\ \qquad 2^{(2)(2)}\cdot 2\\ \qquad (2^2)^2\cdot 2 \end{cases}\implies \sqrt{(2^2)^2\cdot 2}\implies 2^2\sqrt{2}\implies 4\sqrt{2}$

I'll give u brianliest if you share the answer and how you got it

Bogdan [553]

Answer:a is 52 b is 65

Step-by-step explanation:

a:Write 65% as 65100.

65100 of 80 = 65100 × 80.

Therefore, the answer is 52. If you are using a calculator, simply enter 65÷100×80 which will give you 52 as the answer.

b: it is 65 because it is the same question but in reverse which still gives you the same answer.

Hope this helps

Find the surface area of the rectangular prism.<br> 2 cm <br> 6 cm<br> 3 cm <br> 3 cm

Nookie1986 [14]

Answer:

72. If the second 3cm has some relevance, leave a note and I'll come back and modify my answer.

Step-by-step explanation:

Givens

L = 6 cm

W = 3 cm

H = 2 cm

I don't know what the extra 3 cm is for.

Formula

SA = 2*L*W + 2*L*H + 2*H*W

SA = 2*6*3 + 2*6*2 + 2*2*3

SA = 36 + 24 + 12

SA = 72
