(r^2- r^4)- (6r^4+ 2r^2)
= r^2 -r^4- 6r^4- 2r^2
= (r^2- 2r^2)+ (-r^4-6r^4)
= -r^2 -7r^4
= -r^2* (1+ 7r^2).

The final answer is -r^2* (1+ 7r^2).

Hope this helps~

Suppose that the world's current oil reserves is
SOVA2 [1]

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.

Landon puts 30.5% of his paycheck in his savings account. What decimal is equivalent to 30.5%
GarryVolchara [31]

Answer:

0.305

Step-by-step explanation:

When we use the percentage (%) notation, to express for example the happening of a success is X%, we are expressing that the corresponding fact is happening X times every 100 times. Instead of X% we could use X/100.

In this example, every 100 units of his payment check, Landon takes 30,5 unites and puts them to his saving account. So, instead  of 30.5% we could say 30.5/100. (30.5% = 30.5/100).

So, we have:

30.5% = 30.5/100 = 0.305

This way, 0.305 is the decimal equivalent to 30.5%.

Observation: For avoiding comas in the latter fraction we could also say: 305/1000.
