Answer:
Step-by-step explanation:
82.1 = 82 1/10 (thats 82 and 1/10) or 821/10 (if you dont want a mixed number)
7.3 = 7 3/10 or 73/10
9.3 = 9 3/10 or 93/10
if there is 1 number to the right of the decimal, put that number over 10....not the whole number, just the number to the right of the decimal. Leave the number to the left of the decimal alone.
if there were 2 numbers to the right of the decimal, then put those two numbers over 100.
example :
3.43 = 3 43/100
2.76 = 2 76/100
if there were 3 numbers to the right of the decimal, put those 3 numbers over 1000
example :
2.347 = 2 347/1000
3.679 = 3 679/1000
you understand ?
So for this you must ignore the student with 2.
then you see how many in order
1-6 siblings
1-5 siblings
2-3 siblings
add up the left coulumn to get 4 people have more than 3 siblings
2 = degree
x = variable
expression = <span>3x^2-4x+1
coefficients = 3 and -4
constant = 1</span>
<h3>
17) 5ft</h3>
In order to do this problem you must use square roots. Basically the same number multiplied twice to get your answer. In this problem, 5 * 5 = 25.
<h3>
18) 10m</h3>
Since they are asking for the square root to the nearest whole unit, we must know that the √105 lies in between 10 and 11, since 10 * 10 = 100 and 11 * 11 = 121. 105 is closer to 100 than it is to 121 and therefore the answer is 10.
Don't forget your labels!!! (Feet and meters)
The man is 5.5 feet tall
Explanation: 22 is 110 percent of 20, similarly, 5.5 is 110 percent of 5
