It can be helpful to realize the the "%" symbol is a shorthand way to write "/100". That is 9% means exactly 9/100. Of course, you know that hundredths are written in the second decimal place, so
... 9% = 9/100 = 0.09
Answer: 300
Step-by-step explanation:
Answer:
OR = √65
Step-by-step explanation:
M and N are the midpoints of their respective sides, so O is the centroid of the triangle. That means ...
ON = QN/3 = 12/3 = 4
By the Pythagorean theorem, ...
OR² = NR² +ON²
OR² = 7² +4² = 65
OR = √65
Using the Pythagorean theorem, we can find the value of OR as √65 or approximately 8.06 .
In the given figure, we can use the Pythagorean theorem to find the value of OR.
The Pythagorean theorem is a formula that relates the lengths of the sides of a right triangle, which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
This can be seen as c² = a² + b².
M and N are the midpoints of their respective sides, so O is the centroid of the triangle.
Given that QN is perpendicular to PR,ON = QN/3 = 12/3 = 4.
The value of ON =4, and the value of NR = PR/2
NR = 14/2(Because the N is midpoint for PR)
NR =7
By the Pythagorean theorem:-
OR² = NR² +ON²
OR² = 7² +4² = 65
OR = 8.06

x+20=45 is the equation to express how long do spent doing homework.
Two or more expressions with an Equal sign is called as Equation.
Given,
Joe has 45 minutes before he has to go to a soccer practice he spends 20 minutes eating a snack
Rest of the time doing his homework.
We need to form an equation to express how long do spent doing homework.
Let x be the time taken by Joe to make homework.
x+20=45
20 is the time taken for eating snack.
x=45-20
x=25
25 minutes is the time taken by Joe to make homework.
Hence, x+20=45 is the equation to express how long do spent doing homework.
