Your grandmother got out of the hospital she was so excited she gave you some money you decided to go to canada where the exchange rate is $1.06 canadian dollars to $1 us dollar as of november 2013. you have $1 to take with you. how many canadians dollars do you have to spend?

You have $10.600 Canadian dollars to spend.

Step-by-step explanation:

This problem can be solved by a rule of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

In this problem, we have the following measures:

-The number of US dollars

-The number of Canadian dollars.

As the number of US dollars increases, so does the number of Canadian dollars, which means that the relationship between the measures is direct.

The problem states that $1 US dollar is $1.06 Canadian dollars. The problme wants to know how much $10000 is in Canadian dollars. So:

1 - 1.06

10000 - x

x = 10000*1.06

x = $10.600

You have $10.600 Canadian dollars to spend.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
