Find 3/7 • 9/10 as a fraction
Lynna [10]

Answer:

27/70

Step-by-step explanation:

This is simple: First, you multiply the numerators. 3x9 is 27. That is the numerator to your answer.

Next, you multiply the denominators. 7x10 is 70. That's the denominator to the answer.

Put them together and you get 27/70.

Hope I helped!!!

An air freshener starts with 33 grams and evaporates. In each of the following situations define a function that gives the remai
grin007 [14]
Hello!

A) 
<span>The mass of the air freshener A decreases by 3.2 grams each day. Define a function, f, to represent this situation.

In this function, the mass of the air freshener A (m) is the dependent variable and the days (t) and the initial amount of the air freshener A (mi) are the independent variables. If the mass decreases by a fixed amount each day, you only have to multiply this amount by the number of days:

</span>m=mi-(3,2*t)

<span>B) The mass of the air freshener B decreases by 3.2% each day. Define a function, g, to represent this situation.
</span>
This function is trickier since there isn't a fixed amount of decreasing. Instead, the rate of decreasing depends on the initial amount of the freshener (mi). You have to include this initial amount in the equation to correctly model it. This is how you do it:

m=mi-(mi* \frac{3,2}{100}*t)

Have a nice day!

Researchers recorded that a certain bacteria population declined from 110,000 to 400 in 30 hours. At this rate of decay, how man
Arlecino [84]

Answer:

  3137

Step-by-step explanation:

The decay factor is 400/110,000 = 1/275 in 30 hours. Assuming an exponential decay, the equation for the number remaining can be ...

  n(t) = 110,000·(1/275)^(t/30)

Then after 19 hours, the number remaining is ...

  n(19) = 110,000·(1/275)^(19/30) ≈ 3137

There will be about 3137 bacteria after 19 hours.
