Alright! In order to find the answer you'd first write a fraction. The total number of snakes over the amount of snakes that are not venomous. To find which snakes are not venomous you'd subtract 600 from 2700:

[2700 - 600 = 2100].

So, the the fraction of snakes that are not venomous is 2100/2700. and simplified is 4/9.

4/9ths is approximately .77 in decimal form.

How many possibe values of w can there be if w is a number between 39 and 56, w is an even number, and w is evenly divisible by
german

Answer: 3

Step-by-step explanation:

The numbers possible to begin with are 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56 (18 options)

Making it only evens brings it down to 40, 42, 44, 46, 48, 50, 52, 54, 56 (9 options)

Then divisible by three leaves 42, 48, 54 (3 options)

Chris has a collection of 20 baseball cards and Kyle has collection of 40 baseball cards. Chris is adding 3 baseball cards per m
UkoKoshka [18]

Answer:

11 months

Step-by-step explanation:

The initial number of baseball cards that Chris has is 20.

This is like the first term of a sequence.


If Chris is adding 3 baseball cards per month, then there will be a constant difference of 3.

The number of baseball cards after n months is given by the formula;

C_n=20+(n-1)3


\Rightarrow C_n=20+3n-3


\Rightarrow C_n=3n+17 where n\ge1


Similarly, Kyle initially has 40 baseball cards and adds one base ball card per month to  his collection;

The number of his baseball cards after n months is given by the formula;


K_n=40+(n-1)1


K_n=40+n-1


\Rightarrow K_n=n+39


To determine the number of months that will pass before Kyle and Chris have the same number of base ball cards, we equate both equations to get;






\Rightarrow 3n+17=n+39


We group like terms to get;

3n-n=39-17


\Rightarrow 2n=22


\Rightarrow n=11


Therefore Chris and Kyle will have the same number of baseball cards after 11 months.

If the green spinner is spun and then the purple spinner is spun, creating a 2-digit number, what is the probability that the re
Mamont248 [21]

Answer:

2/3

Step-by-step explanation:

It will have to land on 2 or 3 to result in a number greater than 14 because if it lands on 1 the highest number you can get is 14 and that’s not greater than 14 it’s equal to it. The second die is irrelevant in the process if the first die lands on 2 or 3.
