1cm³=1mL
1942cm=x mL
1cm³ 1942cm³
________ = ________
1mL x mL
Cross multiply
1x=1942
divide both sides by 1
x=1942mL
Answer=1942mL
Answer:
x^3 + 1/x^3 = 488
Step-by-step explanation:
- x^2 + 1/x^2 = 62
- x^2 + 1/x^2 + 2 = 64
- ( adding 2 in both sides )
- (x + 1/x ) ^2 = 64
- x + 1/x = 8
now,
- ( x+ 1/x ) ^ 3 = 512
- x^3 + 1/x^3 + 3 × x × 1/x ( x + 1/x )
- x^3 + 1/x^3 + 3 ( 8 )
- ( since x + 1/x = 8 )
- x^3 + 1/x^3 + 24 = 512
- x^3 + 1/x^3 = 488
hence, we got x^3 + 1/x^3 = 488
The sum of -2.5, -3 and 6.7 is 1.2
Any number that ends with 0 or 5 is divisible by 5. If it ends with any other numbers such as 1 2, 3, 4, ,6, 7, 8, 9 then it is not divisible by 5. If a number is divisible by it means that the number can be divided by 5.
5, 10, 15, 20, 25, 1234567890, 9876543210, etc. are going to be divisible by 5 because they end or a 0.
So, look through your given options. Which answer choice has a 0 or a 5 at the end of the number? That's your answer. :)
Hope that helped. (:
