The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.7
Artist 52 [7]

Answer:

24%

Step-by-step explanation:

The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.76)^t . What is the rate of decrease of original oxygen?

The formula for Exponential Decrease is given as:

y = a(1 - r)^t

Where

y = Amount after time t

a = Original amount

r = Rate of decrease

t = Time

Comparing both Equations

y = 0.32(0.76)^t = y = a(1 - r)^t

We know that

0.76 = 1 - r

Solving for r

Collect like terms

r = 1 - 0.76

r = 0.24

Converting to Percentage

= 0.24 × 100

= 24%

Therefore, the rate of decrease of original oxygen is 24%

What is the value of x?
SVETLANKA909090 [29]
The rule for secants tells you
  EC·ED = EB·EA
  (x+4)(x+5) = (x+1)(x+12)
  9x+20 = 13x+12 . . . . . . simplify, subtract x²
  8 = 4x . . . . . . . . . . . . . . add -12-9x
  2 = x

The value of x is 2.

Ben has a collection of 812 stamps. He gives his brother 345 stamps. About how many stamps does Ben have left
dedylja [7]

It is given in the question that

Ben has a collection of 812 stamps. He gives his brother 345 stamps.

And we have to find how many stamps does Ben have left .

Let x stamps are left.

So we have

x+345=812

Subtracting 345 from both sides

x+345-345 = 812-345

x = 467

Therefore after giving 345 stamps to his brother, 467 stamps are left .
