Which is another way to check the sum of 104+34+228+877?

Answers

Answer 1

Answer: The answer is digit sum method.

Digit sum method is method used to check the sum of sum numbers. If the sum of all of the digits of numbers is equal to the sum of all of the digits of the total sum, then the arithmetic process was correct.

We need to check the sum of 104+34+228+877:
104 + 34 + 228 + 877 = 1243

Let's first summarize the digits of individual numbers:
104 *** 1 + 0 + 4 = 5
34 *** 3 + 4 = 7
228 *** 2 + 2 + 8 = 12 *** 1 + 2 = 3
877 *** 8 + 7 + 7 = 22 *** 2 + 2 = 4

Now, let's sum these sums:
5 + 7 + 3 + 4 = 19 *** 1 + 9 = 10 *** 1 + 0 = 1

Then, let's summarize the digits of the total sum:
1243 *** 1 + 2 + 4 + 3 = 10 *** 1 + 0 = 1

Since the sums of the digits on the both sides of equation is 1, than the arithmetic process was correct and the sum of 104 + 34 + 228 + 877 is really 1243.

Which expression is equivalent to i to the power of 233a. 1
b.-1
c.i
d.-i

Answers

i works in a cycle of fours
i^0=1
i^1= i
i^2= -1
i^3=-i
So divide the number by four and whatever the remainder is you use in this key so 233/4 = 58 remainder 1 so that is equivalent to i^1 which is i
So the answer is c) i

$y=(5)/(2)\cdot0+5\ny=0+5\ny=5$

Q, y=5/2x+x if x is zero

An, ( y=5/2×0+5 ) as you know if i multiply number to zero you get zero so "x" change to the zero you get
( y=0+5 )= ( y=5 ) that is your answer

3x + 2y = 1

A.

B.
coincident

C.
consistent and independent

D.
inconsistent

Answers

Answer:

B. coincident

Step-by-step explanation:

An coincident system of equations means that it has infinite solutions, because one line is on the other one. This happens when their equation are the same, or their "parent" line is the same.

So, given equations are:

6x + 4y = 2 and 3x + 2y = 1

Observe that if we divide the first by 2, we have

$(6x + 4y)/(2)=(2)/(2)\n(6x)/(2)+(4y)/(2)=1\n 3x+2y=1$

As you can see, using the first equation, we found that it has the same "parent" equation than the second equation. In other words, they are basically the same. This means that they represent the same line, so, the system is coincident and they have infinite solutions.

After analyzing the data provided in this question one can conclude that they are coincident. For the first system equation we have: 6x + 4y = 2. If we divide everything by 2 we will get: 3x + 2y = 1. Coincident means the same line.

The answer is choice B). Coincident.

Find the coordinates of the midpoint of a segment with the endpoints (16,5) & (28, -13)

Answers

The midpoint can be obtained by taking the averages of the x-coordinate and the y-coordinate. The averages obtained are the new coordinates for the midpoint. This is shown below:

x-coordinate:

X = (16 + 28)/2
X = 22

y-coordinate:

Y = (5 + -13)/2
Y = -4

Therefore, the midpoint has the coordinates M (22 , -4)
