What is the last digit of
[tex]1 \times 3 \times 5 \times 7 \times 9 \times 11 \times 13[/tex]

A. 1
B. 3
C. 5
D. 7​

Answers

Answer 1

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)

Answer 2

Answer:

Answer C. 5

Step-by-step explanation:

Product of Odd and Even Numbers

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.

Answer C. 5

Answer:

40

Step-by-step explanation:

It's basically reverse-simplifying. You can cross multiply, but for me, the easiest thing is to look and see how 3 turned in to 12. To get 12 from 3, you multiply by 4. So then multiply 10 by 4 and you get 40. Hope this helps!! :)

What is the sum of the measures of the interior anles of a convex 13-gon? There is a formula... the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it's (1)180=180 degrees.

Step-by-step explanation:

180(n-2)

n=number of sides

from question, number of sides=13

substitute 13 into the equation given above

Slope=3 y intercept=(0,-1) Second graph: Linear. Third graph: Non linear

Step-by-step explanation:

I recommend using math w ay algebra problem solver to get answer on the first question.

Answer:

1)     slope = 3

       y-intercept = -1

2)     linear

       non-linear

Step-by-step explanation:

In the equation y=mx+b, m is the slope and b is the y-intercept. The number next to the x will always be the slope, and the number after represents the y-intercept.

Linear graphs are always straight lines, the values are always constant.

Non-linear graphs are graphs with curves.

A-one
B-two
C-infinitely many
D-none

Answers

Answer:

c

Step-by-step explanation:

First, I'll isolate the x in x+4y=5 to match with the other equation.

The new equation would be x= -4y+5

Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.

-1(-12y + 15 = 3x )

3(-4y + 5 = x)

The new equations would be :

12y - 15 = -3x

-12y + 15 = 3x

Add the equations and you get

0 = 0

The equation has an infinite amount of solutions
