How many whole minutes does it take 10000 viruses to grow to 1 million if their population doubles every 15 minutes?

nikitadnepr [17]

Let's solve how many whole minutes does it take 10 000 viruses to grow to 1 million if their population doubles every 15 minutes.
=> 10 000 x n = 1 000 000
=> 1 000 000 / 10 000 = 100 times
=> 100 times * 15 minutes = 1500 minutes to make 1 million viruses

Two ropes are attached to a large ballon in a parade. The people holding the ropes are 40 feet apart,and the angle between the t

qaws [65]

Ropes are 9.63 meters ans 8.178 meters.

Step-by-step explanation:

Step 1 :

List all the given things

Distance between people holding ropes = 40 =(40*0.3048) meters = 12.192 meters

Angle between two ropes = 86 degrees

Angle of elevation of one rope = 42 degrees

Step 2 :

Two angles of triangle are already given so third angle can be calculated as -

Third angle = 180 - ( 86 + 42 ) = 52 degrees

Step 3 :

As we know all three angles we will apply sine rule now, which is

$\frac{a}{sine A} = \frac{b}{sine B} = \frac{c}{sine C}$

Step 4 :

By putting values, we have

$\frac{a}{sine 52} = \frac{b}{sine 42} = \frac{12.192}{sine 86}$

Step 5 : Calculating a and b

$a = 12.192 * \frac{sine 52}{sine 86}$ , $b = 12.192 * \frac{sine 42}{sine 86}$

Step 6 :

By putting values of all sine and calculating we get,

a = 9.63 meters and b = 8.178 meters

Write the following number in scientific notation. .00078

Aliun [14]

Answer:

7.8 × 10^-4

Step-by-step explanation:

Although this answer is perfectly O.K., most commonly the base, or the 0.00078, is written as a number with just one digit to the left of the decimal.

To format your number in this way, we'll multiply the .00078 by 10, 4 time(s), making it a 7.8.

We do this, because each multiplication by 10 moves the decimal point to the right one digit.

But in order to keep our number the same number, we must have a × 10-4 next to the 7.8.

So, the final answer is 7.8 × 10^-4
