Answer:
450 km (rider a)
360 km (rider b)
Step by-step explanation:
(if they are going at a constant speed you can choose any point)
find how fast rider a is going:
60/2 = 30 km/h
find how fast rider b is going:
72/3 = 24 km/h
30 km/h for 15 hours = 30 x 15 = 450 km (rider a)
24 km/h for 15 hours = 24 x 15 = 360 km (rider b)
2/5 of the number 100 is 40 because 100÷5=20 that is 1/5 so just add 1/5 of 100, 20, to 20 and you will get 40. hope it helps
Answer:
Option C
10 miles
Step-by-step explanation:
We're given that and the first thing will be to simply the denominators since 15-5=10 and 15+5=20 then the above equation is written as
Bringing like terms together then
Simplifying then
By cross multiplication then m=0.5*20=10
Therefore, m=10 miles
The location AC + CB is mathematically given as
AC + CB= AB
This is further explained below.
<h3>What is the location AC + CB of AB ?</h3>
Because point C can be seen to be in between A and point B, the equation AC + CB must equal AB.
It is important to keep in mind that point C may be located in any part of the space between A and B; yet, the solution will still be considered to be AB in this scenario.
Again, AC + CB = AB.
In conclusion, By way of deduction: if point C is located between points A and B, then it follows that point C is situated on line AB conversely, if point C is not situated on line AB, then it cannot be located between points A and B. As a result, you are able to deduce that AB is a line and that point C is situated on it in the middle of points A and B.

Answer:
6.5 feet
Step-by-step explanation:
Based on the Cosines Law, we have:
If we isolate b (which is our x in this problem), we have
We have
a: 2
c: 5
B: 131 (since it's the complement of the 49 degrees angle: 180 - 49).
So, we plug these numbers in the formula....
We round it up to the tenth of the unit... to get 6.5
