Step-by-step explanation:
<h3>Part A</h3><u>Multiply the energy produced in 1 second by the number of seconds:</u>
10⁻³ is same as 0.001 times and 10³ is same as 1000 times.
1.6*1000 = 1600 mm = 160 cm = 1.6 m is way too big for the measurement of the distance between the tracks on a CD.
So the first option is correct.
Answer:
The daily value for saturated fat is 20g.
Step-by-step explanation:
Percentage problems can be solved by rule of three
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.
A percentage problem is an example where the relationship between the measures is direct.
The problem states that 1g is 5% of the daily value for saturated fat. The daily value(100%) for saturated fat is x, so:
1g - 5%
xg - 100%
5x = 100
x = 20g
The daily value for saturated fat is 20g.
