Answer:
Step-by-step explanation:
I think you mean 1/2 for 12. I will assume so
40 = (1/2) m v^2 Multiply both sides by 2
40*2 = (1/2)*2 *m * v^2 Combine the 2s cancel.
80 = m * v^2 Divide by v^2
80/v^2 = m * v^2/v^2 Cancel
80/v^2 = m
Since I don't have the drop down menus, you'll have do the matching.
Answer:
B
Step-by-step explanation:
Exponents mean the base times itself
So 2^6 = 2 times itself six times
The cardinality of the union between two sets is given by
In fact, if an element is in both A and B, it is counted in both N(A) and N(B), so we're counting it twice. By subtracting the cardinality of the interserction, we're taking back one of these "extra-counted" element, and the count is correct. In your case, the numbers are
This means that the two sets cover, without repetitions, 43 of the 66 elements in the sets. So, there are
elements which are in neither A nor B
Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.
Step-by-step explanation: Let consider the number as ‘X’
Quotient of a number and 5 can be written as
X divided by 5
Ten subtracted from the quotient of a number and 5 can be written as
(X divided by 5)-10
Ten subtracted from the quotient of a number and 5 is 18 can be written as
(X divided by 5)-10=18
By solving the above equation, find ‘X’
(X divided by 5) = 18 + 10
X/5=28
X = 28 x 5 = 140
Answer:
400% of 5 = 5 x 400/100 = 20.
20 > 10 and 20 < 100
Hope this helps!
