A round trip from Montreal to LA is 2,688 miles and takes an airline 9 hours and 20 minutes. Given the outbound trip is the same distance as the return trip, and the speed of the plane was 25%faster on the return trip, how long did the return trip take? Answer to the nearest minute.
Answer:
4.074 hours
Step-by-step explanation:
r =
The formula for speed = Distance × Time
Hence,
Let the outbound speed = r
return trip speed = r + 25x/100 = 125r/100 = 1.25r
Note that: 9 hours and 20 minutes = 9.167
Let t1 and t2 be the time taken to travel on way and return journey.
t1 + t2 = 9 hr 10 min = 9.167 hrs
Hence:
2688/r + 2688/1.25r = 9.167
LCM(1.25r)
(2688 × 1.25) + 2688 /1.25r= 9.167
3360 + 2688 = 9.167 × 1.25r
6048 = 11.45875r
r = 6048/11.45875
Outbound trip rl = 527.8062615904876mph
Return trip speed = r + 25x/100 = 125r/100 = 1.25r
= 1.25 ×
659.75782699mph
Time for return trip = Distance/Speed
= 2,688 miles/659.75782699mph/
= 4.0742222222 hours
Approximately = 4.074 hours

Oceanside bike rental shop charges 16 dollars plus 9 dollars an hour for renting a bike.Sam paid 52 dollars to rent a bike.How many hours did he pay to have the bike checked out?
Answer:
4 Hours
Step-by-step explanation:
Since the equation is:
y = 9x + 16
You have to find x
This is the logical way:
52-16 = 36 because thats the starting fee
So 36 divided by 9 equals 4
You do that because 9 is the charge per hr
So he rented it for 4 hours.
Hope this helps:)

Need help ASAP please!!! The formula determines the magnitude of an earthquake, where I is the intensity of the earthquake and S is the intensity of a “standard earthquake.” How many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6? Show your work.
Answer:
100
Step-by-step explanation:
M = log(I/S)
The intensity of the first earthquake:
8 = log(I₁/S)
10⁸ = I₁/S
I₁ = 10⁸ S
The intensity of the second earthquake:
6 = log(I₂/S)
10⁶ = I₂/S
I₂ = 10⁶ S
The ratio is:
I₁/I₂ = (10⁸ S) / (10⁶ S)
I₁/I₂ = 100
It is 100 times stronger.
An earthquake with a magnitude of 8 is 100 times stronger than an earthquake with a magnitude of 6.
Given the following data:
Magnitude A = 8Magnitude B = 6To determine how many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6:
Mathematically, the magnitude of an earthquake is given by the formula:
[tex]Magnitude = Log(\frac{I}{S} )[/tex]
Where:
I is the intensity of the earthquake.S is the intensity of a standard earthquake.For earthquake A:
[tex]8=Log (\frac{I_A}{S} )\\\\10^8=\frac{I_A}{S}\\\\I_A=S10^8[/tex]
For earthquake B:
[tex]6=Log (\frac{I_B}{S} )\\\\10^6=\frac{I_B}{S}\\\\I_B=S10^6[/tex]
For strength:
[tex]Strength = \frac{I_A}{I_B} \\\\Strength = \frac{S10^8}{S10^6} \\\\Strength = 10^2[/tex]
Strength = 100

Let p=x^2+6p=x 2 +6p, equals, x, start superscript, 2, end superscript, plus, 6. Which equation is equivalent to (x^2+6)^2-21=4x^2+24(x 2 +6) 2 ?21=4x 2 +24left parenthesis, x, start superscript, 2, end superscript, plus, 6, right parenthesis, start superscript, 2, end superscript, minus, 21, equals, 4, x, start superscript, 2, end superscript, plus, 24 in terms of p ?
Answer:
(p+3)(p-7) = 0
Step-by-step explanation:
Given p=x^2+6p and (x^2+6)^2-21=4x^2+24
We are to substitute the the p = x²+6 into the expression as shown;
The expression (x^2+6)^2-21=4x^2+24 will become
(x²+6)²-21 = 4(x²+6)
On substituting p, the expression becomes;
p²-21 = 4p
Subtract 4p from both sides
p²-21-4p = 4p-4p
p²-4p-21 = 0
p²-7p+3p-21 = 0
p(p-7)+3(p-7) = 0
(p+3)(p-7) = 0
Hence the expression in terms of p is (p+3)(p-7) = 0

A high school is having a pancake breakfast fundraiser.They have 5 packages of pancake mix that each feed 140 people.The function N(p)=140p represents the number of people,N(P),that packages of pancake mix feed write the domain and range as compound inequalities.
Answer:
They have 5 packages of pancake mix.
N(p) = 140*p
Represents the number of people that can be feed with p = # of packages of pancake mix used.
Now, the domain will be the set of the possible values of p that we can use here.
the set of possible values of p will be:
{0, 1, 2, 3, 4, 5}
We can not use more than 5 because there are only 5 packages.
But we can use actually half a package or a third, so we not should use only whole numbers in the domain, then the domain can be written as:
D = 0 ≤ p ≤ 5
Now, the range is the set of the possible values of N(p)
The minimum will be when p = 0.
N(0) = 140*0 = 0
The maximum will be when p = 5
N(5) = 140*5 = 700
Then the range can be written as:
R = 0 ≤ N ≤ 700
Here we could add another restriction, because we can only feed a whole number of people, then we also should add the restriction that N must be a whole number:
R = 0 ≤ N ≤ 700, N ∈ Z
