Număr în parc = 106
Numărul din parc reprezintă 1/3 din numărul elevilor care participă la activitatea de curățenie.
Pentru a obține numărul total de studenți care participă la activitate; fie numărul total = x
Prin urmare;
1/3 din x = 106
x / 3 = 106
Înmulțiți ambele părți cu 3
x = 318
Prin urmare, numărul total de studenți implicați în activitatea de curățenie = 318 stuaen

What is compound interest?
What is simple interest?
Answer: Is below
Step-by-step explanation:
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.
Simple interest is a quick and easy method of calculating the interest charge on a loan. Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Answer:
See below.
Step-by-step explanation:
[tex]\boxed{\underline{\text{Compound Interest}}}[/tex]
Compound interest is earned on an investment when the interest earned for each period is added to the previous principal.
Compound interest formula:
[tex]\Longrightarrow: \sf{A=P(1+\dfrac{r}{n})^n^t}}[/tex]
A: represents the current balance or compound amount in the account.P: represents the principal (the original amount deposited).R: annual interest rate (in decimal form).N: the number of times per year that interest is compounded.T: time in years the money has been invested.[tex]\boxed{\underline{\text{Simple interest}}}[/tex]
A simple interest investment is one that earns interest only during the first period but does not earn interest thereafter.
Simple interest formula:
[tex]\Longrightarrow: \sf{I=PRT}[/tex]
I= InterestP= PrincipalR= RateT= TimeI hope this helps, let me know if you have any questions.

Clare is 5 years older than her cousin. cousin How old would Clare be if her cousin is: A. 10 years old? B. 2 years old? C. X years old? Clare is 12 years old. How old is Clare's cousin?
Answer:
if her cousin is 10 clare will be 15, cousin=2 clare=7, cousin=x clare= x+5. if clare= 12 then 12-5=7
The age of cousin when Clare is 12 years old is computed as 7 years.
What is meant by mathematical operations ?Mathematical operations are defined as the operations used for calculating or computing various solutions of two or more values.
Here,
Given that, Clare is 5 years older than her cousin.
Age of Clare at different ages of her cousin is calculated.
A) 10 years old
Age of Clare = 10 + 5 = 15 years old
B) 2 years old
Age of Clare = 2 + 5 = 7 years old
C) X years old
Age of Clare = X + 5 years old
Cousin's age when Clare is 12 years old can be calculated as,
Age of cousin = 12 - 5 = 7 years old
Hence,
The age of cousin when Clare is 12 years old is computed as 7 years.

If $1=Rs. 102.50 and £ 1=Rs, 140, how many dollars equals to £5?
Answer:
$6.83= £5
Step-by-step explanation:
As £ 1=Rs 140
So, £5 = Rs 140 x 5
£5 = Rs 700 ...(i)
Now, Rs. 102.50 = $ 1
So, Rs. 1 = $ (1/102.5)
Therefore, Rs. 700 = $ (1/102.5)x 700 = $6.83
By using equation (i)
£5 = $6.83
Hence, there are $6.83= £5
If one diagonal is 12 inches long and the other is 32 inches long, how many inches long, to the nearest hundredth of an inch, is a side of the rhombus
Answer:
17.09 inch
Step-by-step explanation:
Given that:
A rhombus with diagonals of length 12 inches and 32 inches.
To find:
The length of rhombus to the nearest hundredth of an inch.
Solution:
First of all, we need to learn about the property of a rhombus, its sides and its diagonals.
The diagonals of a rhombus intersect each other by bisecting each other and are perpendicular to each other.
And all the sides
Kindly refer to the attached image for the given dimensions.
Now, there are four right angled triangles in which we can use Pythagorean theorem to find hypotenuse which is nothing but the side of rhombus.
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow Side^{2} = 6^{2} + 16^{2}\\\Rightarrow Side^{2} = 292\\\Rightarrow Side \approx \bold{17.09\ inch}[/tex]

6/a - 4/b = 1 and 9/a - 8/b = 1
Answer:
a = 3 ; b = 4
Step-by-step explanation:
Eqn.1 = [tex] \frac{6}{a} - \frac{4}{b} = 1[/tex]
Eqn.2 = [tex] \frac{9}{a} - \frac{8}{b} = 1[/tex]
Both the eqns have RHS (Right Hand Side) equal. So,
[tex] \frac{6}{a} - \frac{4}{b} = \frac{9}{a} - \frac{8}{b} [/tex]
[tex] = > \frac{6b - 4a}{ab} = \frac{9b - 8a}{ab} [/tex]
Cancelling ab from both the denominators of both the sides,
[tex] = > 6b - 4a = 9b - 8a[/tex]
[tex] = > 8a - 4a = 9b - 6b[/tex]
[tex] = > 4a = 3b[/tex]
[tex] = > a = \frac{3b}{4} [/tex]
Putting the value of a in Eqn.1,
[tex] \frac{6}{ \frac{3b}{4} } - \frac{4}{b} = 1[/tex]
[tex] = > \frac{24}{3b} - \frac{4}{b} = 1[/tex]
[tex] = > \frac{8}{b} - \frac{4}{b} = 1[/tex]
[tex] = > \frac{8 - 4}{b} = 1[/tex]
[tex] = > b = 4[/tex]
Putting the value of b in the value of a
[tex]a = \frac{3 \times 4}{4} = 3[/tex]

Solve in order of operation
Thanks
Answer:
b) 31 and c) 11
Step-by-step explanation:
IMPORTANT: Order of operations is PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/SUbtraction).
B) Solve inside the parentheses first.
1. 2^3 - 6 = (2*2*2) - 6 = 2.
2. Now the equation looks like 3 + 7 (2)^2, Next we need to do exponents.
3. 2 to the power of 2 is 4, leaving you with 3+7(4)
4. Now multiply 7*4, which is 28 then add 3 to it.
So B) would ultimately be 31.
C) As we did in equation B, we start with parentheses.
1. (6/3) we can just simplify this to 2, so those parentheses are out of the way.
2. Now we need to do exponents, (-3)^2. This is the same as -3 * -3. This would equal 9.
3. So far the equation looks like 4 + 9 - 2 / 2.
4. Next would be to solve any multiplication/division problems we have. We can see from step 3 that we have a -2 divided by a positive 2. This would give us -1.
5. Now the equation looks like 4 + 9 - 2. Now you can just working from left to right.
So C) would solve to 11
