What is the last digit of

Mathematics

Papessa [141]2 years ago

Answer:

<em>Answer C. 5</em>

Step-by-step explanation:

<u>Product of Odd and Even Numbers</u>

Any number ending in 5 is necessarily a multiple of 5. For example, 85, 1005, 12345 are all multiple of 5.

Any number ending in 0 is a multiple of 5 and even therefore, is a multiple of 10.

Any integer number multiplied by another number ending in 5 gives one of these possible results:

* A multiple of 5 if the number is odd

* A multiple of 10 if the number is even.

The given product 1*3*5*7*9*11*13 is a multiple of 5 because 5 is one of the factors, and since the rest of the factors are all odd numbers, then the result is a multiple of 5 and has its last digit of 5.

4 0

Step-by-step explanation:

When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).

=> Last digit = 0 or 5.

Since 0 is not an option here, the answer must be 5. (C)

RS has a midpoint at M(7, 10). Point R is at (8, 10). Find the coordinates of point s.
Elena L [17]

Answer:

S(6, 10)

Step-by-step explanation:

1. The Midpoint (in this case, M) will always be halfway between both R and S (or other characters in some cases).

2. As M is only one X value away from R, it is only 1 X value from S as well, but in the other direction.

3. (7, 10) - (1, 0) = (6, 10)

The (7, 10) is the Midpoint Coordinates.

The (1, 0) is the distance from M to R.

The (6, 10) is the coordinates of S.

Find the equation of the line that is perpendicular to y = –3x + 1 and passes though the point (6, 3).
noname [10]

Answer:

A. y=1/3x+1

Step-by-step explanation:

When finding a line that is perpendicular to another line, all you have to do is find the "opposite reciprocal" of the slope. In this case that means writing the slope as the fraction -3/1, and then flipping the fraction over (1/-3) and taking away the negative sign which gets you 1/3 for the slope of your new line. Now, all you have of your new equation is the slope. You need to take your new equation (y=1/3x+b) and plug in the x and y coordinates to that equation, and then solve for the last variable which is b. That solving process goes as follows:

3=1/3*6+b

3=2+b

1=b

now you can replace the b with 1 in your equation to get your final answer of y=1/3x+1
