Answer:
3 and 1/4
Step-by-step explanation:
Bob is hiking down a 12-mile country trail. He could hike at 3 mph for the first two hours and then go the rest of the way at 5 mph or he could just go the whole way at 4 mph. How long would each of these options take? Which option is the faster?
Answer:
The first option will take a total of 3.2 hours while the second option will take just 3 hours
This shows that the second option is faster
Step-by-step explanation:
Here, we want to compare two hiking options and see the one which is faster.
At any point in time;
Distance = speed * time
In the first option, he could hike at 3 mph for two hours.
Total distance covered would be 3 * 2 = 6 miles
Distance left = 12 miles - 6 miles = 6 miles
Time taken to hike 6 miles at 5 mph will be ; 6/5 = 1.2 hours
Total time for the first type hiking = 1.2 hours + 2 hours = 3.2 hours
For the second option;
Time = distance/speed = 12 miles/4 mph = 3 hours
We can see that the second option is faster
Here, we are required to determine how long each of the options take and which of the 2 options is faster .
Therefore;
Therefore;Option 1: 3.2hours
Therefore;Option 1: 3.2hoursOption 2: 3hours.
Therefore;Option 1: 3.2hoursOption 2: 3hours.Ultimately, since option 2 takes 3hours and option 1 takes 3.2hours to hike down the distance respectively, Option 2 is faster.
Total hiking distance = 12 milesFor first option;
He could hike at 3 mph for the first two hours and then go the rest of the way at 5 mph. The statement above suggests that after the first 2 hours, 6 miles will have been covered and the remaining 6 miles can be covered at 5mph in (6/5)hours = 1.2hours.Therefore, the total time taken using this option is;(2 + 1.2) hours = 3.2hours.For second option;
He could go the whole way at 4mph.At this pace, he is able to travel the whole 12mile hiking distance in (12/4)hours.Therefore, the total time taken using this option is; 3hours.Therefore;
Option 1: 3.2hoursOption 2: 3hours.Ultimately, since option 2 takes 3hours and option 1 takes 3.2hours to hike down the distance respectively, Option 2 is faster.

A gym employee is paid monthly. After working for three months, he had earned $4,500. To
determine how much money he will make over a six-month period, he created the table below.
Write an equation to represent the constant of proportionality
Answer:
$9000
Step-by-step explanation:
A gym employee has earned in 3 months =$4500
Then his monthly salary =$4500/3 =$1500
After six months he will earn = 6 × his monthly salary
= 6×$1500=$9000

The required equations are 2x − 3=11 and 2x − 3=−11. Option C is correct.
Given that,
To determine what are the two equations to set up to solve the equation |2x−3|=11.
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given equation,
| 2x − 3| = 11
2x - 3 = ± 11
Taking (+)
2x - 3 = 11 - - - - - - - (1)
Taking (-)
2x - 3 = -11 - - - - - - - - (2)
Thus, the required equation are 2x−3=11 and 2x−3=−11. Option C is correct.

Three girls-- Kali, Annie, and Xiaoling -- go on a trip with their youth orchestra. The three girls share the cost of the hotel. The bill comes to $295.48. It includes $13.25 for some food that Annie orders and $14.00 for cleaning Xiaoling's uniform. What is the dollar amount of each girl's share of the hotel bill?
Answer:
About $107.57
Step-by-step explanation:
if you add up the bill cost and the 13.25 for the food and 14.00 for cleaning Xialing's uniform its $322.73 divide that between the 3 girls and you get about 107.57
Each girl would pay Kali = $89.41
Annie = $102.66
Xiaoling = $103.41
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
Foe example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Total bill amount = $295.48
Now, the amount excluding the amount of food ordered by Annie
= 295.48 - 13.25
= $282.23
and, the amount excluding Cleaning amount
= 282. 23 - 14
= $268.23
So, Each Girl would pay
Kali = $ 268.23 / 3 = $89.41
Annie = 89.41 + 13.25 = $102.66
Xiaoling = 89.41 + 14 = $103.41

Help me pls i need soon
Tksss
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]5^x+5^{x+1}=150[/tex]
First, separate the second term:
[tex]5^x+(5\cdot5^x)=150[/tex]
Let u equal 5ˣ. So:
[tex]u+5u=150[/tex]
Combine like terms:
[tex]6u=150[/tex]
Divide both sides by 6:
[tex]u=25[/tex]
Substitute back u:
[tex]5^x=25[/tex]
Take the base 5 logarithm of both sides:
[tex]\log_5(5^x)=\log_5(25)[/tex]
The left cancels:
[tex]x=\log_5(25)[/tex]
Evaluate the right:
[tex]x=2[/tex]
So, our answer is 2.
And we're done!
