Answer:
5/9
Step-by-step explanation:
Experimental was what actually happened.
Theoretical was what should happen in a perfect, equal world.
E: 6/6 = 1
T: 4/9
E-T= 1-4/9=5/9
Answer:
non-linear because there is not a constant rate of change
Step-by-step explanation:
x y
175 213
167 219
145 179
86 98
175-167=8
167-8=159
The missing value is 3255
Explanation:
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:
x=4
Step-by-step explanation:
