Answer:
1st statement is true
Step-by-step explanation:
The 1st statement is true since .25 is 25/100
The 2nd statement is false since 20 / 10 = 2 not .20 which is 2/10
The 3rd statement is false since 2/3 = .6666667 not .23
The 4th statement is false since .4 = 4/10 not 1/4 which is .25
Answer: 22
Step-by-step explanation:
Answer: option A. 9.2 gal/year
Justification:
The average rate of change from 1960 to 1970 is the change on the variable gallons consumed per passenger car divided by the period
average rate of change = Δg / Δt
Δg = 760 gallons - 668 gallons
Δt = 1970 year - 1960 year
760 gal - 668 gal 92 gal
average rate of change = -------------------------------- = ---------- = 9.2 gal / year
1970 year - 1960 year 10 year
Answer: 9.2 gal / year
As you see for this specific period, 1960 to 1970, the vehicles increased their consumption of gas per passenge, meaning that they became less efficient.

Answer:
15 cos(33°) m
Step-by-step explanation
Presumably m stands for meters.
If RS were 1, x would be cos(33°)
Multiply sides of triangle by 15 m
When calculating cos(33°) first make sure cos(90°) comes out zero, not -0.448...
