The best way to explain it is to provide a couple of examples.
<u>Example 1:</u> 1.111 x 10³ multiplied by 5
= (1.111 x 5) x 10³
= 5.555 x 10³
<u>Example 2:</u> 6.666 x 10³ multiplied by 5
= (6.666 x 5) x 10³
= 33.330 x 10³
= 3.3330 x 10⁴
Answer: multiply the numbers together and then include 10ⁿ. Convert answer into scientific notation afterward, if needed.
Answer:
y = 49
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 21 when x = 6 , then
21 = 6k ( divide both sides by 6 )
3.5 = k
y = 3.5x ← equation of variation
When x = 14 , then
y = 3.5 × 14 = 49
Make it an improper fraction with two as the denominator, and you'll get 9/2. There are 9 halves in 4 1/2 meters
