Answer:
1st, 3rd and 4th
Step-by-step explanation:
Only 2nd is false
Equation for circumference is c = 2(pi)r
r = 1/2(d)
d = 20
So…. r = 1/2(20) = 20/2 = 10
Going back to circumference equation
c = 2(pi)(10) = 2(3.14)(10) = 62.8
Answer:
16.5x == 465.3
Step-by-step explanation:
To find the rate , take the number of miles and divide by the gallons
rate = 465.3 / 16.5
Let the rate be x
x = 465.3 / 16.5
Multiply each side by 16.5
16.5x = 465.3
Answer:
0.09
Step-by-step explanation:
avg rate of change is: change in y/ change in x
so it´d be 3.59 - 0.89 / 2014 - 1984
= 2.7/ 30
= 0.09
note:
The slope formula and the average rate of change formula are the same, just written a bit different, so you could also use:
y2 - y1 / x2 - x1
