Answer:
1. AB is a diameter. (False)
2. ST, SP and SQ are radii. (True)
3. SQ = 12 cm. (False)
4. PQ is 12 cm. (True)
Step-by-step explanation:
1. AB is not a diameter because a diameter must pass through the center of the circle.
2. ST, SP and SQ are radii because they all meet at the center of the circle.
3. SQ is not equal to 12 cm. SQ is equal to 6 cm because it is a radius.
4. PQ is equal to 12 cm because it is a diameter. Radius = 6 cm. Diameter = 2 × radius = 2 × 6 cm = 12 cm
Answer:
x = -7/4
Step-by-step explanation:
"Eight times a number equals 4 times that number less 7."
Subtracting 4x from both sides of this equation, we get:
4x = -7
Dividing both sides of this result by 4 yields
x = -7/4
Answer:
24 hours
Step-by-step explanation:
4·10 = 40
180 - 40 = 140
140/7 = 20 hours from Mon - Fri
4 hours on Sat
20 + 4 = 24
