A counterexample shows that one side is true while the other is false

x>7 and x>11

sub in the answers

9>7 and 9>11 -this is true for the first half but false for the second

5>7 and 5>11 -this is false for both

13>7 and 13>11 -this is true for both

15>7 and 15>11 -this is true for both

Are the ratios 2:3 and 12:18 equivalent?

lesya692 [45]

Answer: Yes

Step-by-step explanation:

Yes, they are, because if you multiply 2*6=12 and 3*6=18, so here we multiplied both 2 and 3 by the same number (6) and we got the same result 12:18. This method also works with fractions.

A stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer. If the top laye

Svetlanka [38]

Answer: The total number of logs in the pile is 6.

Step-by-step explanation: Given that a stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer and the top layer has two logs.

We are to find the total number of logs in the pile.

Let n represents the total number of logs in the pile.

Since each subsequent layer has 6 fewer logs then the previous layer, so the number of logs in each layer will become an ARITHMETIC sequence with

first term, a = 32 and common difference, d = -6.

We know that

the n-th term of an arithmetic sequence with first term a and common difference d is

$a_n=a+(n-10)d.$

Since there are n logs in the pile, so we get

$a+(n-1)d=2\\\\\Rightarrow 32+(n-1)(-6)=2\\\\\Rightarrow 32-6n+6=2\\\\\Rightarrow 6n=36\\\\\Rightarrow n=6.$

Thus, the total number of logs in the pile is 6.

Select 4.0625 as a mixed number in simplest form.

coldgirl [10]

(4.0625/1) * 10000 = 40625/10000. That simplifies to 65/16. The mixed number is 4 1/16
