Answer:
The area of the sidewalk is 144.44 m².
The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.
Since the radius is half the diameter, r = 25/2 = 12.5.
The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².
The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.
The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

First let's define the variables of the problem:
t: Tip
b: dinner bill.
We write the inequality based on the following proposition:
"Maria would like to leave a tip (t) of at least 15% of her dinner bill (b)"
We have then that the inequation is:
t> = 0.15b
Answer:
An inequality best could be used to find the amount of the tip Maria would like to leave is:
t> = 0.15b
Answer:
not a function. domain = -2, 3, 8 (you don't have to write them in any specific order and you also don't need to write -2 twice)
Step-by-step explanation:
to be a function, all of the x's must be different
Answer:
a.the car is traveling at the speed of 126 km/h
b.the car will cover 630 km in 5 hours
Step-by-step explanation:
first of all we will convert meter in kilometer and second in hour
1 m = (1/1000) km
1s = (1/3600) h
35m/s = 30m/s *(1/1000)km/m *(3600)s/h
now we will cancel the units
35m/s = 35 *(1/1000)km *(3600)/h
= 0.035 * 3600
= 126km/h
