132 m/s
Explanation:
Average speed is defined as the distance traveled divided by the time of travel, so in your case
v
=
528 m
4 s
=
132 m/s
Since 9 times 8 is 72, and 7200 is close to that number, a proper estimate would be 800.
Answer:
d
Step-by-step explanation:
A linear parent function is the equation y = x or f(x) = x. A parent function is the simplest equation of a function. Thus, f(x) = x is the simplest of all linear functions and that is the reason why it is called linear parent function.
Answer:
67.33.
Step-by-step explanation:
To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.
To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.
Answer:
6%
Step-by-step explanation:
- 90 + 60 = 150
- 7 + 2 = 9
- Set up a proportion:
- Cross multiply, then divide: 9 × 100 = 900, 900 ÷ 150 = 6
- So, 6% of students in 6th grade were left-handed
