Answer:
Step-by-step explanation:
Given that,
The surface Area of a cube is equal to the sum of the 6 Square faces
And each side has a length of 's'
Formula to calculate the surface area is
A = 6s²
Given that the surface area is 1944 units²
It is a straight forward question,
The questions already gave us the formula for area of a cube and which is 6s² and the question said that if the area is 1944 unit², find 's'
So,
A = 1944
6s² = 1944
s² = 1944 / 6
s² = 324
s = √324
s = 18 units
So, the value of s- is 18 units
Answer:
The simplified sum of these polynomials is 3x^4y - 2xy^5
Step-by-step explanation:
In order to find this, we need to remember that we can only add together like terms in this case, there are only two like terms. Both of the first terms end in x^2y^2. So, we add these two together.
3x^2y^2 - 3x^2y^2 = 0
Since they cancel out, we simply just put the other two terms as our answer.
3x^4y - 2xy^5
Answer:
(D) xy/(x + y)
Step-by-step explanation:
To find r in terms of x and y
Given,
- two resistors with resistances x and y are connected in parallel
- r is the combined resistance of these two resistors
- the reciprocal of r is equal to the sum of the reciprocals of x and y
Then,
1/r = 1/x + 1/y
1/r = (y + x)/xy
Find the reciprocal of both sides
r = xy/(x + y)
The right answer is option (D) xy/(x + y)
Probabilities are used to determine the chances of events
The probability that the first erroneous bit is the 28 bit is 0.0076
<h3>How to determine the probability</h3>
The given parameter is:
p =1% --- the probability that a bit has errors
The probability that the first erroneous bit is the 28 bit means that the first 27 bits do not have errors.
So, we have:
The equation becomes
Evaluate
Hence, the probability that the first erroneous bit is the 28 bit is 0.0076

An integer is a whole number.
1) if Isaac is on the 4th floor and goes up 7, that is 4 + 7= 11. So he is on the 11th floor.
2) the integer representing the floor he is starting on is 4 because that is the whole number associated with "4th."
3) the integer representing how many floors he will rise is 7.
4) the elevator will stop at 11.
Hope this helps! :)
