M stands for a whole number greater than 10 and less than 20n stands for a whole number greater than 2 and less than 10

1. What is the smallest number that m x n could be?
2. What is the largest number that m - n could be?

Answers

Answer 1
Answer: 10 < m < 20
So m can be 11, 12, 13, 14, 15,16, 17, 18 or 19

2 < n < 10
So n can be 3, 4, 5, 6, 7, 8 or 9
Q1. What is the smallest number that m times n could be? That would be the product (the "times") of the two smallest number in each range, so 11 times 3 = 33.

Q2. What is the largest number that m - n could be? Here we want to make the difference between the two numbers the largest. So we take the largest value for m which is 19 and the smallest number for n, which is 3.

19 - 3 = 16.

You are asked to draw a triangle using three of the following angles: 0°, 30°, 45°, 55°, 60°, 80°, 90°, 105°. Which triangle cannot exist?A) 30°, 60°, 90°
B) 45°, 55°, 80°
C) 30°, 45°, 105°
D) 30°, 45°, 55°

Answers

Answer:

D

Step-by-step explanation:

When you add all the the angles of a triangle, they  will end up to be exactly 180 degree. When you add the three numbers A, B, and C end up with 180 degree, but D end up with 130 degree, therefore, D is the triangle that cannot exist.

Hope it helps :D

How do you reduce 42/70- math

Answers

Well i think you mean to simplify 42/70 which is:

(2 * 3 * 7) / (2 * 5 * 7)
= ((2 * 3 * 7) : (2 * 7)) / ((2 * 5 * 7) : (2 * 7))
= (42 : 14) / (70 : 14) = 3 / 5

Eric's notebook has 30 pages. He wants to write a number on each page. How many digits will he write when he numbers all the pages in the notebook?

Answers


i think it would be ... 60 because 30 times 2 = 60 and on each page there are 2 pages the one in the front and the one in the back .... I hoped i gaved u the right answer
when you number something it depends wethor or not you are using 0 as a place holder (01 02 03 ect.) if so the answer would be 60 because all you have to do is multiply by two. If you are not using place holders the answer would be 59 because 30*2=60-9 you take away 9 beace there were nine place holders (Zero)

F(x, y) = 4x + 7y - 6, please find the value of f(5,-5).

Answers

f(x, y) = 4x + 7y - 6

substitute x=5 and y=-5

f(5,-5) = 4(5) + 7(-5) - 6

f(5,-5) =20-35-6

        = -15-6

        =-21
