The rate of change is given as 10 per day--the number of cans the class plans to bring each day.

After 10 days at that rate, the change will be 10*10 = 100. Since the total after 10 days is 205, we compute the initial value as 205 -100 = 105. This is the number the teacher already had.

cans = 10*days +105

What are two ratios that are equivalent to 27:9
skad [1K]
For this case we have the following relationship:
 27:9
 To find two equivalent relationships, what we must do is divide both numbers by a number that is multiple of both.
 We then have to divide by three:
 9:3
 Then, dividing again between three we have:
 3:1
 Answer:
 two ratios that are equivalent to 27:9 are:
 Ratio 1:
 9:3
 Ratio 2:

Answer:

  the probability is 2/9

Step-by-step explanation:

Assuming the coins are randomly selected, the probability of pulling a dime first is the number of dimes (4) divided by the total number of coins (10).

  p(dime first) = 4/10 = 2/5

Then, having drawn a dime, there are 9 coins left, of which 5 are nickels. The probability of randomly choosing a nickel is 5/9.

The joint probability of these two events occurring sequentially is the product of their probabilities:

  p(dime then nickel) = (2/5)×(5/9) = 2/9

_____

<em>Alternate solution</em>

You can go at this another way. You can list all the pairs of coins that can be drawn. There are 90 of them: 10 first coins and, for each of those, 9 coins that can be chosen second. Of these 90 possibilities, there are 4 dimes that can be chosen first, and 5 nickels that can be chosen second, for a total of 20 possible dime-nickel choices out of the 90 total possible outcomes.

  p(dime/nickel) = 20/90 = 2/9

If A line has a y -intercept of 10 and a slope of 4 . What is its equation in slope -intercept form
chubhunter [2.5K]

Answer:

<h2>          y = 10x + 4</h2>

Step-by-step explanation:

The equation of a line in slope-intercept form is: y = mx + b, where <em>m</em> is a slope and<em> b</em> is y-intercept.

m = 10

b = 4

So, the equation:  y = 10x + 4
