Answer:
A.
Explanation:
Associate property of multiplication: a × (b × c) = (a × b) × c
Option A
Shows associate property of multiplication. Does not change final answer.
Option B
The grouping does not change inside the parenthesis.
Option C
This does show associate property but multiplying first 8 × 1/3 is complex.
Option D
Product of this changes the final answer. Not correct.
Answer:
A. 50.38
Step-by-step explanation:
Bill is 38.96. Calculate sales tax: 38.96x.0775=3.02.
38.96 + 3.02=41.98 total before tip
41.98x.20=8.40 tip
41.98 + 8.40=50.38
Answer:
The slope of the line is 14 pounds per day
Step-by-step explanation:
We are given that The local hiking club went on a 7-day hiking trip to Denali National Park.
The group started with 98 pounds
We are also given that the decreasing amount of food each day is modeled by a linear function
On Day 1 amount of food = 98 pounds
Since day 7 was the last day
So, On Day 8 amount of food = 0
So,
Slope = Constant Rate of change per unit
Slope =
So, Slope =
Slope = - 14
Negative sign shows decreasing amount of food each day
Hence the slope of the line is 14 pounds per day
This is what a local maximum is:

I don't know the answer but hope this helps you figure it out.</span>
