Given:1st grade:
19%2nd grade:
14%3rd grade:
22%4th grade:
26%5th grade:
19%TOTAL : 205 students.To find -Since the total students have been given, we just have to find the percentage of the 205 students that are 5th graders (19%).
So this can be found out:
19% of 205
Solution:
Always use this formula to find a percentage:
% / 100 = Part / Whole replace the given values:
19 / 100 = Part / 205
Cross multiply:
19 x 205 = 100 x Part, or
3895 = 100 x Part
Now, divide by 100 and get the answer:
Part = 3895 / 100 = 38.95
Since decimal cant be a whole number round to nearest tenth:
First note that 38.95 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 38Fractional Part: 95To round 38.95 to nearest tenth means to round the numbers so you only have one digit in the fractional part.
We use the following rules to round 38.95 to the nearest tenth:
A) If the last digit in the fractional part of 38.95 is less than 5, then simply remove the last the digit of fractional part.B) If the last digit in the fractional part of 38.95 is 5 or more and the first digit in the fractional part is less than 9, then add 1 to the first digit of the fractional part and remove the second digit.C) If the last digit in the fractional part of 38.95 is 5 or more and the first digit in the fractional part is 9 then add 1 to the Integer part and make the fractional part 0.With 38.95, rule C applies and the answer is:
39.0

Each equation below is followed by several stories.
Select all of the stories that can be represented by the equation.
If none of the stories can be represented, select "None of the above".
(a)x+11=44
Answers
Typically, there are keywords in the story that tell us what operations we need to use.
For instance, in terms of age:
"Younger" or "older" connotes to subtraction from the age of the older person. It can also connote to the addition to the age of the younger person."Years ago" typically connotes to the subtraction of x years from the person's current age."More years" typically connotes to the addition of x years to the person's current age.Solving the QuestionLet's take a look at our first option.
Yousif is x years old. Rana is 44 years older than Yousif. Rana is 11 years old.Firstly, this option doesn't even make sense. How can Rana be 11 years old but also 44 years older than Yousif?
Let's look at our second option.
Rana is x years old. in 11 more years, she will be 44 years old.Immediately, we see "11 more years". This means that we will be adding 11 to Rana's current age, which is x:
[tex]x+11[/tex]
This expression above is equal to 44, since the question tells us that Rana will be 44 years old in 11 years:
[tex]x+11=44[/tex]
This is our final expression. It is the same as the given expression in the question.
AnswerRana is x years old. in 11 more years, she will be 44 years old.

In a quadrilateral OABC, D is the midpoint of BC and E is the point on AD such that AE : ED=2: 1. Given that OA = a, OB = b and OC = c, express OD and OE in terms of a, b and c.
Answers
Answer:
Step-by-step explanation:
CB=OB-OC;
CD=CB/2=(OB-OC)/2=(b-c)/2;
OD=OC+CD=c+(b-c)/2=c/2+b/2;
AD=OD-OA=c/2+b/2-a;
AE=2/3*AD=2/3*(c/2+b/2-a)=c/3+b/3-2*a/3;
OE=OA+AE=a+c/3+b/3-2*a/3=a/3+b/3+c/3;
-------------------------------------------------------------------------------------------------
OD=c/2+b/2;
OE=a/3+b/3+c/3;
The value of OE = (a+ b+ c)/3 and OD = (b + c)/2.
In quadrilateral OABC, we are given that D is the midpoint of BC,
and E is a point on AD such that AE : ED = 2 : 1.
Also, OA = a, OB = b and OC = c
Now, By the Midpoint Theorem, we also have
OD = (1/2)OB + (1/2)OC.
OD = (1/2)(OB + OC)
OD = (1/2)(b + c)
OD = (b + c)/2.
and, CD= (OB- OC)/2 = (b-c)/2
Now, AD=OD-OA= (c+b)/2 - a
and, AE=2/3 x AD
= 2/3 x (c+ b)/2 - a
= (c + b - 2a)/3
Then, OE = OA + AE
= a + (c + b - 2a)/3
= (a+ b+ c)/3

Please remember that an arithmetic sequence is a sequence where we use either addition or subtraction to get to the next term.
Now, let's find an arithmetic sequence here.
Is it Option A?
Remember: It should have a common difference of 2.
Which means we either add or subtract 2 to get to the next term.
Well, it seems like Option A is right.
Let's check the other options.
Is Option B right? Nope.
Here's why.
Hint: Pay attention to the signs.
We have
1, -3, 5, -7, 9...
So Option B is wrong.
Option C is correct, because we subtract 2 each time.
Option D is wrong, because we multiply by 2 each time.
Hence, the right options are
