I NEED SERIOUS ANSWERS WITHIN 15 MINUTES PLEASE, WILL MAKE BRAINLIEST

Can anybody help me out please

romanna [79]

Answer:

175(130)^t) < 1200

Step-by-step explanation:

The occupancy is 1200 so it must me less than 1200 (<1200)

the number of people in at any time is 100% of the people in or 1.00

and it increases by 30% or 0.30 (1.30)

And it starts with 175 people (1.75)

so

start people / How its increases / to the power of t / less than capacity

175 (1.30) $^{t}$ < 1200

a product code consists of picking a two-digit number (including 00) and 3 not necessarily distinct letters. How many codes are

Brrunno [24]

Answer:

The codes are:

N,_,_,_

Where each _ represents a possible letter, out of 26.

And N is a number of two digits.

So in total we can think that we have 5 empty slots.

_,_,_,_,_

In the first slot we can put any digit between 0 and 9, so here we have 10 options.

In the second slot we can put any digit between 0 and 9, so here we have 10 options.

In the third slot we can put any letter, so here we have 26 options (and exactly the same for the fourth and fifth slots)

The total number of different combinations is equal to the product of the number of options for each slot.

C = 10*10*26*26*26 = 1,757,600

Now, if we want to have at least one nine, we can fix it in the first slot.

Then we have:

in the first slot we have only one option (the 9)

In the second slot we can put any digit between 0 and 9, so here we have 10 options.

In the third slot we can put any letter, so here we have 26 options (and exactly the same for the fourth and fifth slots)

The number of combinations is:

C = 1*10*26*26*26 = 175,760

But we also should consider the case where we fix the 9 in the second slot, so the actual number of combinations is twice the number above.

C = 2*175,760 = 351,520

The probability that the code does not contain the number 9.

Now in the first slot we have only 9 options, all the whole numbers between 0 and 8.

The same for the second slot, 9 options.

For the third, fourth and fifth slot is the same as before.

The total number of combinations is:

C = 9*9*26*26*26 = 1,423,656

PLEASE HELP. D: !!!!

attashe74 [19]

Answer:

52 seconds
7093 feet

Step-by-step explanation:

This is the kind of problem that is most easily solved graphically, because the solution point coordinates give both the time and the altitude.

The attached graph shows the planes both arrive at the altitude of 7093 feet after 52 seconds.

__

The equations for altitude in feet (y) as a function of time in seconds (x) are ...

y = 3687 +65.5x . . . . . plane A

y = 5000 +40.25x . . . plane B

Subtracting the second equation from the first gives . . .

0 = -1313 +25.25x

x = 1313/25.25 = 52 . . . . . . . add 1313 and divide by the x-coefficient

y = 3687 +65.5(52) = 3687 +3406 = 7093

After 52 seconds both planes have an altitude of 7093 feet.
