The inequality that models this situation is 150x + 350 y ≤ 250000 and x + y < 1200

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let x represent the number of wheat acres and y represent the number of corn acres, hence:

150x + 350 y ≤ 250000 (1)

Also:

x + y < 1200 (2)

The inequality that models this situation is 150x + 350 y ≤ 250000 and x + y < 1200

What value of z makes the equation z+6÷13=4 true?

netineya [11]

Answer:

z = 46/13

Step-by-step explanation:

Step 1: Write equation

z + 6 ÷ 13 = 4

Step 2: Solve for z

Rewrite: z + 6/13 = 4
Subtract 6/13 on both sides; z = 46/13

Step 3: Check

Plug in z to verify it's a solution.

46/13 + 6/13 = 4

52/13 = 4

4 = 4

Step-by-step explanation:

YELLOW TRIANGLE:

$\sin(30) = \frac{x}{12} \\ x = 12 \sin(30) = 6$

PURPLE TRIANGLE:

Since one of the angle is 45°, x = BC = 6

To prove:

$\tan(45) = \frac{bc}{x} \\ bc = x \tan(45) = 6 \tan(45) = 6$

PINK TRIANGLE:

$\tan(60) = \frac{bc}{y} \\ y = \frac{bc}{ \tan(60) } \\ = \frac{6}{ \tan(60) } \\ = 2 \sqrt{3}$
