Answer:

1  1/3 cups of juice

Step-by-step explanation:

Let the volume of the container be c, which is measured in cups.

Then (2/3)c = (8/9) cups juice.  We must solve this for the container volume, c.

      (8/9) cups

c = ----------------

           2/3

Inverting the divisor (2/3) and multiplying, we get:

      3(8/9 cups)

c = ------------------ =  12/9 cups, or 4/3 cups, or 1 1/3 cups.

             2

The container originally held 1 1/3 cups of joice.

How do you find a if given c and 0 (angle) in a right triangle where a is the opposite, c is the hypotenuse, b is adjacent and 0
Yakvenalex [24]
C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))

William is setting up for folding chairs for a meeting he arranges the chairs and seven rows of the same link he has three chair
DiKsa [7]

Answer:

William has a total of 66 chairs.

Step-by-step explanation:

Let the number of chairs in each row be 'x'.

Also let the Total number of chairs be 'y'.

Given:

If he arranges the chairs in seven rows of the same length he has three chairs left

Number of rows = 7

Number of chairs left = 3

Now we can say that;

Total number of chairs will be equal to number of chairs in each row multiplied by Number of rows plus Number of chairs left.

framing in equation form we get;

y=7x+3

Also Given:

If he arranges the chairs in five rows of the same length he has 21 chairs left

Number of rows = 5

Number of chairs left = 21

Now we can say that;

Total number of chairs will be equal to number of chairs in each row multiplied by Number of rows plus Number of chairs left.

framing in equation form we get;

y=5x+21

Now we know that Total number of chairs are same.

Hence we can say that both the equations are equal.

7x+3=5x+21

Combining like terms we get;

7x-5x=21-3\\\\2x= 18

Dividing both side by 2 we get;

\frac{2x}{2}=\frac{18}{2}\\\\x=9

So we can that there are 9 chairs in each row.

Now to find the total number of chairs he has we will substitute value of x in any of the equation we get;

y =7x+3\\\\y=7\times9+3\\\\y=63+3 =66

Hence William has a total of 66 chairs.
