At the beginning of an experiment, there are 400 grams of contaminants. Each hour, three-fourths of the contaminants are filtered out.


Use the model to calculate the number of contaminants after the third hour of the experiment.

the answer is not 168.75 cause that is how much filtered/went away. I need to know how much is left after it was filtered.

Answers

Answer:

18.75

Step-by-step explanation:

first hour: 400×(1/4) = 100

second hour: 100×(1/4) = 25

third hour: 25×(1/4) = 18.75

but i have to give credit to the first answerer, this is not my answer, though i know how to do it i dont know how to explain it properly.

3x2 − 8x + 4

Answers

Answer:

(3x - 2) (x - 2)

Step-by-step explanation:

im smart

First multiply 3 and 4 to get 12. Now, we must get two numbers that multiply to 12, but also add to -8. The answer is -6 and 2.

Now rewrite this expression as “3x^2-6x+2x+4.

Now, group together each set of two terms and find the GCF of each. The GCF of 3x^2 and -6x is -3x. The GCF of 2x and 4 is 2.

Now, divide each group by the GCFs and place them next to each other. You should get -3x(x+2)+2(x+2). We know this is correct because the parentheses match.

Now, rewrite the duplicate factors as one, and group together what is outside the parentheses. The final answer is...

(-3x+2)(x+2).

To check, you can double distribute (FOIL) to see if it matches the original expression.

Answers

Answer:

  -15/16  

Step-by-step explanation:

The sum of a geometric series with first term a1 is ...

  S = a1/(1 -r)

Then the common ratio (r) is ...

  r = 1 -a1/S

For the given values, the ratio is ...

  r = 1 - 124/64 = -15/16

The common ratio is -15/16.

The number of planes in a year will be 219000 planes.

How to calculate the value in a year?

Rate demonstrates how many times one number can fit into another number. Rate contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

Here, 150 planes arrive in 6 hours. The number of planes in a day which is 24 hours will be:

= 150 × (24/6)

= 600 planes.

The planes in a year will be:

= 600 × 365

= 219000 planes.

The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.

Does the cost of the chemical increase or decrease with time?

Group of answer choices

Increase

Decrease

Answers

9514 1404 393

Answer:

  increase

Step-by-step explanation:

Your cost function appears to be an exponential function of the form ...

  c(x) = (initial cost)·(growth factor)^x

When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).

The cost function increases with time.

the wheel?

49.7 cm?
198.9 cm?
99.5 cm
19.6 cm?

Answers

Answer:

49.7 [tex]cm^{2}[/tex]

Step-by-step explanation:

Although it is hidden a bit, we are actually given the circumference of the circle, which is 25 cm.

We know that C = 2πr, so we can substitute variables to find the radius (r).

25 = 2πr

r = 25/(2π)

r = 3.9788... cm

The area of a circle is A = π[tex]r^{2}[/tex], so:

A = π [tex]3.9788^{2}[/tex]

A = 49.7359... [tex]cm^{2}[/tex]

A ≈ 49.7 [tex]cm^{2}[/tex]

Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many fish did Jacob catch last year?

Answers

Answer:

12 fish

Step-by-step explanation:

You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.

[tex]\frac{30-6}{2}[/tex] = x

[tex]\frac{24}{2}[/tex] = x
