Answer:
<u>27</u> students are girls.
Step-by-step explanation:
Given:
There are 3/4 as many girls as there are boys.
In the fifth grade total there are 63 students.
Now, to find the number of students that are girls.
Let the number of students that are boys be 
So, the number of students that are girls = 
Total number of students = 63.
Now, to get the number of students that are girls we solve an equation:
Now, substituting the value of 
:
Therefore, 27 students are girls.
Answer:
For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.
Step-by-step explanation:
We all know, the Pythagorean theorem can be stated as follows:
The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.
i.e.
Where, 
is the hypotenuse and 
are the two other legs of the right angled triangle.
Given that:
and 
are rational numbers.
To find:
Situation for which is irrational.
Square of a rational number is always rational.
So, 
both will be rational.
And sum of squares of two rational numbers will also be rational.
Therefore, 
will also be rational.
and
For the value of can be irrational, sum of squares of other two legs might be imperfect square number.
Acceleration is the change in velocity over time. There's are formula's for such problems which are called kinematics equations. Look em up. One of them doesn't have t (time) in them you would normally use that one to solve this problem. 16/2/20=a=0.4m/s^2
I did it for you but please look it up, understand and memorize it ;)
5 object which are longer than your hand- span in my surrounding is Note book, Laptop, Window, Curtain, Table.
Hand span is a measure of distance from the tip of the thumb to the tip of the little finger with the hand fully extended.
Hand span is a measure that has been used for many years. By placing the hand on the edge of a piece of paper and marking the tips of the thumb and little finger, the student can measure a straight line. This is a better method than placing the hand directly on the ruler.
Hand span and cubit are not used as standard units of length because their sizes vary from person to person. So, two different persons may give different measurements for the same length, which is not desirable for a standard unit.
Measure using yours hands and write as per your hand-span measurement.
Therefore,
5 object which are longer than your hand- span in my surrounding is Note book, Laptop, Window, Curtain, Table.
