First we think of a 3 digit dividend for example 100.
Next we think of a divisor between 10 and 29 for example 20.
We divide 100÷20=5

Here's a division problem:

Sophia has 100 pencils. She has 20 boxes with the same number of pencils in them. How many pencils does Sophia put her box?

Divide 100 by 20 which equals 5

Your answer is 5

Kaya devoted 2/5 of her study time to mathematics, 3/20 of her time to social studies, 1/3 of her time to chemistry and the rema

andrezito [222]

Answer:

54 minutes

Step-by-step explanation:

The sum of fractions is ...

2/5 + 3/20 + 1/3 = 11/20 +1/3 = (3·11 + 20·1)/(20·3) = 53/60

Then the 42 minutes devoted to English represents 1 - 53/60 = 7/60 of her study time.

Kaya's social studies time is 3/20 = 9/60 of her total, so the ratio of SS to Eng is ...

SS : Eng = (9/60) : (7/60) = 9 : 7

When we multiply the numbers in this ratio by 6, we find ...

SS : Eng = 54 : 42

Kaya spent 54 minutes studying social studies.

Tritium is a radioactive isotope of hydrogen that decays by about 5% per year. A large bottle of water that contained 450,000 tr

Basile [38]

Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

In this problem:

The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.

The amount decays by about 5% per year, hence r = 0.05.

Thus, the equation is given by:

$A(t) = A(0)(1 - r)^t$

$A(t) = 450000(1 - 0.05)^t$

$A(t) = 450000(0.95)^t$

After 11 years, the amount is given by:

$A(11) = 450000(0.95)^{11} = 255960$

The bottle contains 255,960 atoms of tritium after 11 years.
