How do you get 100 percent on scantron?
Answer 100% of the questions/problems correctly.
How many questions would you miss to get 80 percent out of 20 problems?
Four questions.
How do you find the percent of a number?
The first step in calculating the percent of numbers is to change the percent to a decimal. When you see the word "of" in word problems, that signals multiplication, so take the decimal and multiply by the number.
What happens to the circumference of a circle when the radius is increased by 50 percent?
The circumference is directly proportional to the radius. So increasing the radius by 50% causes the circumference to also increase by 50%.
What is 65 percent of 100?
65. That's one of the simplest math problems you will ever face.
How does proportional reasoning relate to percent?
A percent is a proportion with the denominator equalling 100.
If two quantities are directly proportional when one quantity increases by 10 percent what does the other do?
If two quantities are directly proportional, when one quantity increases by 10 percent, the other quantity will also increase by 10 percent. This means that the relationship between the two quantities remains consistent as they change by the same proportion.
Where does 70 percent of crashes involving cars and bicycles occur?
Driveways or intersections
If you have 50 math problems and you do 48 percent of them how many problems have you done?
24 problems
Why is a 5 percent sales tax on gasoline regressive?
This is a fixed rate (proportional) tax, not a regressive tax.
2 and one half percent as a decimal?
.025 Keep in mind one percent = .01, that makes it easier to solve questions involving %'s!
Why are rectangles still similar if you increase dimensions by 50 percent?
They are similar because their sides are proportional and their angles are equal.
What are the advantages of using A readings rather than percent T as a means of estimating microbial growth?
The density of a cell suspension is expressed as absorbance (A) rather than percent T, since A is directly proportional to the concentration of suspended cells, whereas percent T is inversely proportional to the concentration of suspended cells. Therefore, as the turbidity of a culture increases, the A increases and percent T decreases, indicating growth of the cell population in the culture.
In 1991 about what percent of incidents involving police use of force were reported to involve civilian shootings?
10
What of these is not a risk factor for teen drivers?
fifty six percent of crashes involving teens occurred on a weekday
Which of these is not a risk factor for teen drivers?
Fifty-six percent of crashes involving teens occurred on a weekday.
What are the major types of stoichiometry problems?
The major types of stoichiometry problems involve calculating the quantities of reactants and products in a chemical reaction. This includes determining mole ratios, mass-mass relationships, limiting reactants, and percent yield. Other common types of problems include volume-volumetric relationships and stoichiometry involving gases.
