<h3>How many hours would it take to
type 3.2 x 10^5 words?</h3>
Standard form is used in expressing large numbers in smaller numbers. It is used to transform large numbers into smaller number.
In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example: 1 x 10² is equivalent to 100
The first step is to determine how many words he can type in 1 hour : 40 x 60 = 2400 words = 2.4 x 10³
The second step is to divide 3.2 x 10^5 words by 2.4 x 10³
3.2 x 10^5 ÷ 2.4 x 10³ = 1.33 x 10^(5 - 3)
1.33 x 10^2 hours

Explanation:
You need to divide 12.75 by 3 in order to find the price of one ticket.
Answer:
y = 16.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 15 when y = 12, that is
12 = 15k ( divide both sides by 15 )
= k, so
k = 0.8 y = 0.8x ← equation of variation
When x = 21, then
y = 0.8 × 21 = 16.8
123.875 i think is the answer
