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.

Find the slope of the line passing through the points (-18, -5) and (-19, -13)
Answer:
Let (-18, -5) be (x1,y1)
(-19, -13) be (x2,y2)
slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8
Answer: The slope is 8.
Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.

Answer:
See Explanation
Step-by-step explanation:
m = 46° (vertical angles)
j = 92° (vertical angles)
j + k + 46° = 180° (staright line angles)
92° + k + 46° = 180°
138° + k = 180°
k = 180° - 138°
k = 42°
n = 37° + 44° = 81°

Answer:
62.22%
Step-by-step explanation:
First, find how many total marbles there are:
12 + 11 + 17 + 5
= 45
Then, find how many marbles that are not blue:
12 + 11 + 5
= 28
Then, divide 28 by 45, and multiply by 100
(28/45) x 100
= 62.22% is the probability of not choosing a blue marble

Answer:
0.00565 miles / second
Step-by-step explanation:
1 mile = 1609.344 meters
100 meters = 100/1609.344 = 0.0621 miles (aprox)
100 meter/ 11 seconds = 0.0621miles / 11 seconds

Let b represent the hours Liz spends babysitting. Let t represent the number of hours she spends tutoring. Given that Liz can work at most 12 hours per week, write an inequality that models the number of hours she spends babysitting and tutoring in a week.
Answer:
b+t < 12 (< has a line under it)
Step-by-step explanation:
Liz can work at most 12 hours per week. So, add the number of hours she spends babysitting, b, and the number of hours she spends tutoring, t, in a week, and represent the sum as less than or equal to 12:
b + t < 12

A. 33cm
B. 0.002
C. 0.03
D. 7500 cm
Answer:
Option C - 0.03 cm
Step-by-step explanation:
The model has a length of 15 cm.
Now, we are told that the scale is 1:500. This means that 1 unit is represents 500 cm on the model.
Since the length on the model is 15 cm which is 15 units, then the true length would be;
15 × 1/500 = 0.03 cm
Therefore, the true length is 0.03 cm.
Option C is correct

Write the Linear Equation in Point-Slope Form for a line that has a slope of
-10 and passes through the point (8,2). *
Answer:
y = -10x + 82
Step-by-step explanation:
Plug in the slope and point into y = mx + b to solve for b:
y = mx + b
2 = -10(8) + b
2 = -80 + b
82 = b
Then, plug b and the slope into y = mx + b
y = -10x + 82 is the equation in point slope form.
