Verizon [17]

Answer:

6:2,\,9:3

Step-by-step explanation:

Given: The ratio of cups of sparkling water to cups of grape juice concentrate is 3:1 in a recipe for fizzy grape juice.

To find: two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe

Solution:

Equivalent ratios are the ratios that have the same value.

Find two ratios equivalent to 3:1=\frac{3}{1}

Multiply both numerator and denominator of \frac{3}{1} by 2

\frac{3(2)}{1(2)} =\frac{6}{2}

Multiply both numerator and denominator of \frac{3}{1} by 3

\frac{3(3)}{1(3)} =\frac{9}{3}

So, two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe are 6:2,\,9:3

Answer:

Step-by-step explanation:

The tangent of the angle can be found using the identity for the tangent of the difference of angles.

  tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))

The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.

  tan(α) = -2/3

  tan(β) = 4/7

  tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))

  = (-14-12)/(21 -8) = -26/13 = -2

Then the magnitude of the angle between the vectors is ...

  arctan(2) ≈ 63.43°

Solve for X-4 1/6 = 9 1/3
Gala2k [10]

Answer:

  13 1/2

Step-by-step explanation:

X-4 1/6 = 9 1/3

Add 4 1/6 to each side

X-4 1/6+ 4 1/6 = 9 1/3 + 4 1/6

x = 9 1/3 + 4 1/6

  = 9 2/6 + 4 1/6

   13 3/6

    13 1/2
