Answer:
-1

Explanation:
3π / 4 = (3*180) / 4 = 135 degrees
Since 135 is in the 2nd quadrant, therefore:
tan (135) = - tan (45) = -1

cot θ = 1/tanθ
Therefore:
cot (3π / 4) = 1/tan(3π / 4)
cot(3π / 4) = -1

Hope this helps :)

Answer:

y = -7

Step-by-step explanation:

Put x = 2 in any one of the equation

5x +2y = -4

5*2 + 2y = -4

10 +2y = -4

      2y = -4 -10

      2y = -14

        y = -14/2

         y = -7

The statements that apply to the ratio of rice and water are:

  • The ratio of rice to water is 1 to 2.5
  • The ratio of water to rice is 2.5 to 1

<h3>Ratios</h3>

Ratios are used to compare quantities of different measurements

The entries on the table are given as:

<u>Rice          Water</u>

2                  5

3                  7.5

5                 12.5

8                 20

<h3>The ratios of both quantities</h3>

The ratio (r) of rice and water is then calculated as:

r = \frac{Water}{Rice}

Pick any corresponding table entry.

So, we have:

r = \frac{5}{2}

Divide

r = 2.5

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1
