CALCULATOR! Sorry but I mean....really?
Answer:
a)
Step-by-step explanation:
its the same thing if you multiply 3×4 and 4×3 for example
and you get the same result both times
575 / 14
Use easy multiples of 14 that do not exceed 575. Use 10.
(1) 14*10 = 140 575 -140 = 435
(2) 14*10 = 140 435 - 140 = 295
(3) 14*10 = 140 295 -140 = 155
(4) 14*10 = 140 155 - 140 = 15
Now you cannot use another 10*14. Then just divide 15 by 14 which gives 1 and have remainder 1
(5) 15/14 = 1
15 - 14 = 1 = Remainder
Then, the sum of the partial quotients is 10+10+10+10+1 = 41; and you have remainder 1, therefore 575 = 41*14 + 1
And the result of the division is 575/14 = 41 plus remainder 1
Answer:
An equation of the form y = kx can be thought of as an equation of the form y = mx + b where m = k and b = 0.

Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²
