The no. of quarters will be 4 and no. of dimes will be 6.
It is given that Total value of jar of quarters and dimes = $8.80
We have to found the no. of quarters and no. of dimes.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , division , etc.
As per the question ;
Total value of jar of quarters and dimes = $8.80
Also ;
Number of quarters is 8 less than twice the number of dimes.
Let's assume the number of dimes be x.
So ;
The no. of quarters = 2x - 8
and
Total value will be equal to ;
2x - 8 + x = 8.80
3x = 16.80
x = 16.80 ÷ 3
or
No. of dimes = x = 5.6 ≈ 6
And no. of quarters will be ;
= 2 × 6 - 8
= 12 - 8
= 4
Thus , the no. of quarters will be 4 and no. of dimes will be 6.

write a problem based on the information given c = regular cost of one airline ticket 0.2c = amount of 20% promotional discount 3(c - 0.2c) = 330
The question for this information:
The cost of buying 3 airline tickets at a promotional discount of 20% is 330 dollars. Find the regular cost of 1 ticket.
Discounts and allowances are price reductions from a product's or service's base price.
Discount is calculated by subtracting the sell price of an article from its Marked price.
The given conditions in the question are
C=regular cost of a ticketamount of promotional discount=20%=0.2cAnd the expression 3(c - 0.2c) = 330So from the above information we can see that if the price of a ticket is c dollars then the discounted price of 1 ticket will be (c - 0.2c).
Total price of 3 tickets =3(c - 0.2c)
but the total price is 330 dollars
Therefore:
3(c - 0.2c) =330
or, 2.4c=330
or, c=330÷2.4
or, c=137.5 dollars
Hence the regular price of each ticket is 137.50 dollars.

4. Philips is given an interest free loan to buy a LCD television. He needs to repay the loan by monthly instalments. He repays RM35 for the first month, RM38 for the second month and the repayment increase by RM3 each month until the loan is fully settled.
(a) Show that the monthly instalment earned form an arithmetic series and state its common difference. [2 marks]
(b) If the final monthly instalment if RM212, calculate the number of months it takes Philips to settle the loan. [4 marks]
(c) Determine the sum of the loan taken. [4 marks]
The monthly instalment amounts forms an (a) Arithmetic Progression with common difference 3. (b) Phillips takes 60 months to settle the loan. (c) The sum of the loan is $7410 .
A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
The n-th term of an arithmetic progression is given by:
aₙ = a + ( n - 1 ) d
Where a is the first term and d is the common difference .
(a) Amount of money repaid in the first month = $35
Amount of money repaid in the second month = $38
Amount of money repaid in the third month = $ (38+3) = $ 41
Therefore 41 -38 = 3 and 38 - 35 = 3 . So we see that each monthly instalment is increasing by 3 and the difference between each installment is 3
Therefore the numbers are in an arithmetic progression whose common difference is 3 .
(b) Given the final monthly installment is $ 212
Let us consider that after this is the installment for the n-th month.
∴ aₙ =212 , a= 35 and d=3
Putting the values in the equation of the n-th term of an AP we get:
aₙ = a + ( n - 1 ) d
or, 212 = 35 +(n-1)3
or, 212 - 35 + 3 = 3n
or, n = 60 months
Therefore Phillips takes 60 months to settle the loan.
(c) The formula for the sum of all terms of an AP is given by:
S = (n / 2 ) ( a + aₙ )
or, S = (60/2) × (35+212)
or, S = 30 × 247
or, S = 7410

The positive integer between 1 and 100 that cannot be represented as a whole percent are 8, 15, 36 and many more.
How to find the positive integer that cannot be represented as a whole percent?The class has 99 students.
One student of the class is 1% of the class when rounded to the nearest whole percent. The actual percentage of one student is 1 / 99 × 100 = 100 / 99 = 1.0101010101%

The perimeter of a rectangle is the sum of the lengths of all its sides.
Formula
Perimeter of rectangle= 2(width) +2(length)
Substitute the given information into the formula:
92= 2(2x +3) +2(x +7)
Expand:

Craig’s job pays him $18.75 per hour, plus overtime at
the usual rate. Last month, Craig worked the following
hours per week:
• Week 1 = 37 hours
• Week 2 = 47 hours
• Week 3 = 42 hours
• Week 4 = 39 hours
The monthly payment to Craig is $ 3093.75
Given,
The payment got by Craig for his job = $ 18.75 per hour
Weekly working hours of Claig:
Week 1 = 37 hours
Week 2 = 47 hours
Week 3 = 42 hours
Week 4 = 39 hours
We have to find the total monthly payment of Craig:
That is,
Week 1 + Week 2 + Week 3 + Week 4
For getting the weekly salary, we have to multiply hourly payment with hours worked:
So,
Week 1 = 37 × 18.75 = 693.75
Week 2 = 47 × 18.75 = 881.25
Week 3 = 42 × 18.75 = 787.5
Week 4 = 39 × 18.75 = 731.25
Now calculate the total monthly payment:
That is,
693.75 + 881.25 + 787.5 + 731.25 = 3093.75

A cannonball is fired in the air at an angle of 45∘. How far does it travel before it is
1,700 feet above ground? (Assume the cannonball travels in a straight line. Ignore the force of gravity and wind resistance. Give your answer to the nearest foot.)
It travels 2404 feet before it is 1,700 feet above ground;
The given question can be represented in the form of equation;
y = tan(45°)x + c;
Since it is launched from ground; c = 0;
thus; y = x is the equation of motion of cannonball;
According to question; y = 1700 feet
x = 1700 feet;
The distance travelled by cannonball will be
√(x² + y² = √(1700² + 1700²) (∵ it is a right angled triangle;
using Pythagoras theorem)
= 2404.16 feet
≅ 2404 feet
