Answer:
A
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = 
To find k use the condition y = 48 when x =
, thus
k = yx = 48 ×
= 16
y =
← equation of variation
Answer:
Its the symbol "pi" which is 3.14
First, we'll need to find the definition for "unit cost" and "unit rate"
What is a unit rate?
Rates are usually expressed as a quantity of 1 such as 2 feet per second or 5 miles per hour
The words: miles per hour or feet per hour is a unit rate.
What is a unit cost?
Unit costs are used as a measure of a company's cost to build one unit of a product. This includes fixed costs and variable costs.
In conclusion.
Unit rates and unit costs are almost the same thing. But, they're sometimes used in different ways.
Answer: 12
Step-by-step explanation: To find the least common multiple or lcm of 4 and 12, begin by listing the first few multiples of each number.
<em><u>Multiples of 6</u></em>
1 × 6 = 6
2 × 6 = 12
3 × 6 = 18
Notice that we skipped 0 × 6 in our list of multiples.
That's because 0 × 6 is 0 and our least common multiple can't be 0.
When listing the multiples of 12, it's a good idea to keep an eye on the list of multiples for 4 so that we will notice when we find a least common multiple.
<em><u>Multiples of 12</u></em>
1 × 12 = 12
Notice that 12 is also a multiple of 6 so our least common multiple is 12.
We can stop here because all other multiples
that we find will be greater than 12.
So the least common multiple or LCM of 4 and 12 is 12.
