Answer:

1. 14.5

2. 16

Step-by-step explanation:

1. a^2 + b^2 =c^2

20^2 + 21^2 = c^2

400 + 441 = c^2

841 = c^2

\sqrt{841} = \sqrt{c}

29 = c

29/2 = x

14.5 =x

2. c^2-b^2 = a^2

34^2 - 30^2 = a^2

1156 - 900 = a^2

256 = a^2

\sqrt{ 256 } = \sqrt{a}

16 = a

Answer:

Equation: y = \frac{7}{4} x

21/2 cups of water

Step-by-step explanation:

Plug in 7 as y and 4 as x

7 = 4k

Find k

k = 7/4

Then plug k into th equation

y = 7/4 x

For the second part of the question:

Plug in x which is 6 into the bolded equation.

y = (7/4)(6) = 42/4 = 21/2 (simplified form)

21/2 cups of water
