5 0

Answer:

  A)  R = 1900 -24t

  B)  1684 billion barrels

  C) 79.17 years

Step-by-step explanation:

<h3>A)</h3>

Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.

  R = 1900 -24t

__

<h3>B)</h3>

For t=9, the reserves will be ...

  R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels

__

<h3>C)</h3>

The reserve will be 0 when ...

  0 = 1900 -24t

  24t = 1900 . . . . . add 24t

  t ≈ 79.17 . . . . divide by 24

Reserves will be gone in about 79.17 years.

The degree measures of the angles of a triangle are represented by x, 3x and 5x -54.
lora16 [44]

Answer:

x = 26

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + 3x + 5x - 54 = 180 , that is

9x - 54 = 180 ( add 54 to both sides )

9x = 234 ( divide both sides by 9 )

x = 26

A raffle is being held to benefit the local animal shelter. They sell 717 tickets that do not win any prize, 19 tickets that win
matrenka [14]
Let’s start by finding the total amount of tickets sold

717+19+1=737

Now multiply by 5 to see how much money they initially brought in

737•5=3,685

Now let’s find the total expense of the prizes

166+(19•20)=t

166+380=546


Now subtract the expenses from the total ticket sales

3,685-546=3,139


They made $3,139 TOTAL


Now let’s divide the total made by the total tickets sold

3139 / 737 = 4.26


They made $4.26 PER TICKET


Hope this helps!
