Solve the system of inequalities: a) .4x−1≤0 <br> 2.3x≥4.6

OleMash [197]

Answer:

(a) $x \leq 2.5$

(b) $x \geq 2$

Step-by-step explanation:

Solving (a):

$0.4x - 1 \leq 0$

Add 1 to both sides

$0.4x - 1 + 1\leq 0 + 1$

$0.4x \leq 1$

Solve for x

$x \leq 1/0.4$

$x \leq 2.5$

Solving (b):

$2.3x \geq 4.6$

Solve for x

$x \geq 4.6/2.3$

$x \geq 2$

Question 1 (0.5 points)

Finger [1]

Answer:

39.91 degrees.

Step-by-step explanation:

Formula

Sin(A)/a = Sin(B) / b

Givens

A = 84
a = 31
B = ?
b = 20

Solution

Sin(84)/31 = Sin(B)/20

20*Sin(84) / 31 = Sin(B)

Sin(B) = 0.6416

B = 39.91 degrees.

====================

This looks like it is right, but you should check. Let h be the height opposite angle A.

h/20 = sin(39.91)

h = 20*sin(39.91)

h = 12.83

31 has to be longer than that amount (which it is.) So there is one solution.
