Total journey of bob was 108 miles .
<u>Step-by-step explanation:</u>
Here we have , Bob traveled 90 miles which was 83 1 3 % of his trip. We need to find How long was the trip .Let's find out:
According to question , Bob has traveled a distance of :
⇒ 
Which is 
of his journey . So , Let total miles be x , So we have following equation framed according to question as :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , Total journey of bob was 108 miles .
II. f(x) doubles for each increase of 1 in the x values. Thus, r must be 2, and so we our ar^1 = 6 from ( I ) above becomes f(x) = a*2^x. Applying the restriction ar^1 = 6 results in f(1) = a*2^1 = 6, or a = 3.
Then f(x) = ar^x becomes f(x) = 3*2^2 (Answer A)
Hi, thank you for posting your question here at Brainly.
Since the hedge is surrounding the square base, the area of the base can be determined by subtracting the area of the base from the hedge.
A = pi*r^2 - (4x)^2
A = pi*(6x)^2 - (4x)^2
A = 2x^2*(3pi - 2)
I hope I was able to answer your question. Have a good day.
X = 4 , y = -1
Explanation:
solve by elimination ie eliminate x or y from the equations by performing operations on them.
first label the equations , to follow the process.
x - y = 5 ----------------(1)
x+ y = 3 ----------------(2)
If (1) and (2) are added then y will be eliminated.
(1) + (2) gives : 2x = 8 → x = 4
now substitute this value of x into either of the 2 equations and solve for y.
let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1
check in (1) : 4-(-1) = 4+1 = 5
check in(2) : 4 - 1 = 3
