Answer:
<em>x=60°</em>
<em>x=48°</em>
<em>x=21°</em>
Step-by-step explanation:
<u>Inequalities</u>
The sum of the exterior and the interior angle of a triangle is 180°.
The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.
This angle is said to be at least twice x, thus:
180 - x ≥ 2x
Adding x:
180 ≥ 3x
Dividing by 3:
60 ≥ x
Swapping the inequality:
x ≤ 60°
The measure of x must be less or equal to 60°.
Three possible solutions are:
x=60°
x=48°
x=21°

Answer:
The first bottle has 4 pints or 8 cups or 2 quarts. The seconds has 1.25 quarts or 5 cups or 2 1/2 pints. The one with 4 pints would have more so it would be a better deal.

Answer:
(0,7) is one the x axis beacuse the 0 is first

Part (d)
Answer: 180 degrees
----------------------
Explanation:
QS is a diameter, which makes angle SPQ to be 180 degrees (ie a straight angle). Arc QTS is also going to be 180 degrees, because all semicircles are half of the full circle of 360 degrees. So (1/2)*360 = 180.
==================================================
Part (e)
Answer: 50 degrees
----------------------
Explanation:
Angle QPR is a central angle that subtends (cuts off) the minor arc RQ, which is shown to be 50 degrees. The central angle is equal to this arc measure, so angle QPR is also 50 degrees
