c
Step-by-step explanation:
150 is a good sample of a middle school and students at lunch is random again because most students eat lunch
Meters are 100 times as large as centimeters. So, if we have 800 centimeters, that is the equivalent of 8 meters.
In this scenario, we want to know how many meters is equivalent to 7
centimeters. Since 1 centimeter is 1/100 of 1 meter, we can multiply the
amount of centimeters by 1/100 to get the measurement in meters.
7(1/100) will yield 7/100 or .07 meters.
To write this in scientific notation, we take 7 and multiply it by 1/100 or 10^(-2). This is written "7x10^(-2) m".
7 centimeters in scientific notation is just 7x10^0 because it is a
single unit. Scientific notation allows us to compare the size of
numbers more easily.
For instance 7.12x10^3 is much larger
than 7.12x10^(-3) due to the exponents and how many "10s" we are
mulitplying our number by.
Answer:
10
Step-by-step explanation:
To answer this question you will use ratios. The information given gives us a part to part ratio of 1 part vinegar for every 3 parts oil.
Because the total amount of furniture polish is 30 ounces, we will need to write one part vinegar to three parts oil as a part to part to whole ratio.
Use this information then and create an equivalent ratio with a total of 30 ounces. See below.
1 vinegar (x7.5) = 7.5 ounces
3 oil. (X7.5). = 22.5 ounces
4 total (x7.5). = 30 ounces
You will need 7.5 ounces of vinegar and a 22.5 ounces of oil.
