Answer:

5

Step-by-step explanation:

<u>Given</u><u> </u><u>:</u>

  • b = 3
  • y = -7

<u>To </u><u>Find</u><u> </u><u>:</u>

  • Value of 4b - y .

<u>Solution</u><u>:</u>

Put on the respective values ,

⇒ 4b - y = 4 × 3 - 7

⇒ 4b - y = 12 - 7

⇒ 4b - y = 5

<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>5</u><u> </u><u>.</u>

The mean sustained wind velocity, v, can be determined by the equation v = 6.3 StartRoot 1013 minus p EndRoot, where p is the ai
olya-2409 [2.1K]

Answer:

910 millibars

Step-by-step explanation:

According to the Question,

  • Given That, The mean sustained wind velocity equation v=6.3*\sqrt{1013-p} And The mean sustained wind velocity is 64m/s (v=64) . where, p is the air pressure(in millibars).

Now, the air pressure at the center of a hurricane when the mean sustained wind velocity is 64 m/s is

64=6.3*\sqrt{1013-p}\\\frac{64}{6.3} = \sqrt{1013-p}\\

on squaring both sides we get,

(10.1587)² = 1012 - p  ⇒ p = 908.80≈910millibar

p = 910millibars air pressure .
