Answer:8
Step-by-step explanation:
First, substitute 7 into the equation for b:
1/3(2x7+10)
Now, simplify using the order of operations:
1/3(14+10)
Then:
1/3 (24)
And you arrive at your answer:
8
Length of circular track is:
L = 2*r*pi
He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi
To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds
v = L'/t = 3*r*pi/2*105
v = r* pi/70
If we take that r = 1
answer
Answer:
6 miles
Step-by-step explanation:
x = miles driven
4.00 + 2.75 * x = 20.50
2.75x = 20.50 - 4.00 = 16.50
so
x = 16.50/2.75 = 6 miles
The answer is 1.38 gallons
becuase 12 + 6 = 18
then 18 / 13 is 1.384615385
but you cant write that down so we round to the nearest hundreth and you get 1.38 as your final answer
