Marty has 3 white T-shirts, 2 coloured T-shirts, and 4 sweaters. What is the ratio of T-shirts to sweaters?

5:4

Step-by-step explanation:

3 shirts+2 shirts= 5 shirts

4 sweaters

5:4   OR    5/4   OR    5 to 4

Step-by-step explanation:

First of all, I just want to explain that the answer can be written in the three different ways above.

To solve this question, first we need to know what a ratio is:

Ratio: In mathematics, a ratio indicates how many times one number contains another.

For example, if there are 8 oranges and 6 lemons in a bowl full of fruit, then the ratio of oranges to lemons is 8 to 6

Now, back to the question ⇒

The question is asking for the ratio of T-shirts to sweaters so we need to add all the T-shirts. It doesn't matter if the T-shirt is blue or white, etc.

3 + 2 = 5

5 T-shirts in total.

Then we see how many sweaters there are, which is 4.

There are 5 T-shirts to 4 sweaters, giving us the ratio 5:4

I hope that was helpful! Brainliest??? ;P

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
