Answer:
20. 8% increase = 108% total
2,550 × 1.08 = 2,754
D. 2,754 square feet
21. 25% off + 10% off = 65% total
239.99 × 0.65 = 155.9935
A. $156
22. Adding a negative number is the same as just subtracting.
D. 14 + (-9)
23. C. There is a change in temperature from -3°F to 3°F
24. C = pi × d
C = pi × 8
C = 25.1327
B. 25.1 units
25. 20 ÷ 4 = 5 pages per hour
25 ÷ 5 = 5 pph
D. Yes, because 20/4 = 25/5
26. A = Pi × r^2
9 ÷ 2 = 4.5
4.5^2 = 20.25
C. 20.25pi square inches
27. 100 ÷ 5 = 20
A. m = 20n
30. 250 + 20 - 270 = 0
A. Deposit $20 in the first week and withdraw $270 in the second week
31. 7.44 ÷ 24 = 0.31
A. C = 0.31b
32. -3(-6b + 5)
-3(-6b) + -3(5)
18b + (-15)
D. 18b - 15
33. -13.74 × 4 = -54.96
A. -54.96 feet
Answer:
D.130°
Step-by-step explanation:
An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.
-Given that AC and BC are diameters, then since they are alternate angles.
#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:
Hence, mBC=130°
Answer:
Step-by-step explanation:
y ÷ 3(4 - 2) + 5.5
= y ÷ 3(2) + 5.5
= y ÷ 6 + 5.5
= y/6 + 5.5
= (y + 33)/6
