11/6+3 is 29/6. 2/(29/6) is 12/29, which is the answer.

The correct answer is:


1250 skiers and 2500 snowboarders.


Explanation:


The ratio is 1:2. We are told that more snowboarders buy season tickets than skiers; this means the ratio is skiers/snowboarders.


Let x be the number of skiers that bought season tickets. Since 1250 more snowboarders bought season tickets, this means the number of snowboarders would be represented by x+1250.


We can use the ratio to set up a proportion:


(1)/(2)=(x)/(x+1250)


Cross-multiply:


(x+1250)(1) = x(2)

x+1250 = 2x


Subtract x from each side:

x+1250-x = 2x-x

1250 = x


This means the number of skiers is 1250.

The number of snowboarders would then be 1250+1250 = 2500.

v = l*w*h

divide by wh on each side

v/wh =lwh/wh

v/(wh) = l

Answers

Answer:

The reasonable domain is the set of natural numbers.

Step-by-step explanation:

When we talk about a reasonable domain for a function, we refer to all values inside the domain set that makes sense to the problem which models the function. For example, if the function models people's age, then the reasonable domain must be all positive integers.

In this case, we have the function

f(x)=3.25x

Where x represents the number of cars.

The mathematical domain refers to the comple domain set, using negative and positive numbers. However, the mathematical domain doesn't make sense to this problem, because the domain represents cars, and they cannot be represented by negative numbers and decimals.

So, the reasonable domain to this function is the set of all natural numbers, because they are positive and integers.

Therefore, the right answer is the first choice.

Draw a line with the given slope through the given point.

(-4,1) slope=3/5

Answers

I can't put. Graph out but I can give you points. Since it says 3/5 you must go up three and over five(my teacher likes to call it the rise/run method). So here are the points

(1,4)

(6,7)

And the point you already gave, (-4,1). Hope this helped!
