Select the correct answer from each drop-down menu. the four vertices of an inscribed quadrilateral divide a circle in the ratio
AleksandrR [38]

The four angles of a quadrilateral are  30°, 60°, 150°, and 120°  if the four vertices of an inscribed quadrilateral divide a circle in the ratio 1:2:5:4.

<h3>What is quadrilateral?</h3>

It is defined as the four-sided polygon in geometry having four edges and four corners.

We have the four vertices of an inscribed quadrilateral divide a circle in the ratio:

1:2:5:4

Let the sides of the quadrilateral be x, 2x, 5x, 4x.

We know the sum of all angles of quadrilateral = 360°

x+2x+5x+4x=360

12x = 360

First angle, x = 30°

Seconds angle, 2x = 2×30 ⇒ 60°

Third angle, 5x = 5×30 ⇒ 150°

Fourth angle, 4x = 4×30 ⇒ 120°

Thus, the four angles of a quadrilateral are  30°, 60°, 150°, and 120°

Answer:

x > −4

Step-by-step explanation:

Step 1: Add 5 to both sides.

6x-5+5 > -29+5

6x>-24

Step 2: Divide both sides by 6

6x/6 > -24/6

x > -4

A beverage manufacturer is mixing up a 30% tomato juice blend. The manufacturer already
Mariulka [41]

Answer:

1110 liters

Step-by-step explanation:

Let x = amount of 26% juice.

Amount of tomato juice:

740 liters of 36% juice contains 0.36(740) = 266.4 liters of tomato juice

x liters of 26% juice contains 0.26x liters of tomato juice

The result will be x + 740 liters of the juice blend at a concentration of 30%. It contains 0.3(x + 740) liters of tomato juice.

266.4 + 0.26x = 0.3(x + 740)

266.4 + 0.26x = 0.3x + 222

-0.04x = -44.4

x = 1110

Answer: 1110 liters
