Answer:
100 litres
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
First, factorize the number 3,240:
So,
Now consider the fraction
If k = 10, then
is a square number.
For all k < 10, the fraction tex]\dfrac{3,240}{k}[/tex] is not a square number (this follows from factorization).
Or you can simply check the values of the fraction for all k < 10:
- k = 1, is not a square number;
- k = 2, is not a square number;
- k = 3, is not a square number;
- k = 4, is not a square number;
- k = 5, is not a square number;
- k = 6, is not a square number;
- k = 7, is not a square number;
- k = 8, is not a square number;
- k = 9, is not a square number.
Answer:
x = or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)
You can divide the total number of outcomes.
Add 2.38 and 4.89 then subtract 3 giving you 4.27
