in 2019 there were 16 named storms, of which 8 grew into hurricanes and 5 were major. What fraction of hurricanes were major?
olga2289 [7]
There were 16 total storms, meaning our denominator is 16. Since 8 grew into hurricanes, we can leave that alone. Since 5 out of 16 storms were major, 5 is our numerator.

5/16 storms were major because 8 were hurricanes and the other 3 were other kinds of storms. As a decimal conversion, about 31% of these storms were major.

How to find the percentage conversion:

Step 1: We take the fraction 5/16.

Step 2: Since our numerator is 5 and the default denominator is a maximum of 100, we can multiply 5 by 100.

5 x 100 = 500

Step 3: We can divide 100 by 16 to get our decimal conversion.

100 divided by 16 will give us 31.25, which also is representative of 31 and 1/4 added together.

Your final answer: With there being 16 storms, 5 of these storms are major (5/16). In terms of if there were 100 total storms, about 3/10 of these storms were major.

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car use
klemol [59]

Answer:

200 litres

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd\sqrt{s} ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × \sqrt{100} = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d\sqrt{s} ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × \sqrt{64} = 0.025 × 1000 × 8 = 200
