In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.
Answer:
Dos numeros primos
Step-by-step explanation:
31 y 37 no son productos de dos números naturales más pequeños. Los otros numeros entre 30 y 40 son compuestos.
All the points if they lay on top of eachother
if they arent on top of eachother, they can intersect at 2 points
In geometry, the three undefined terms are: the point, the plane and the straight line.
Since all the given graphs represent lines,we will need to choose the straight line among them.
Straight line is a line that has no start and no end.
From the choices:
Figures a and c are rays
figure b is a line segment
figure d is a straight line
Therefore, the correct choice is: D
Answer:
Tyrone's rate is 1 more mile per hour than John's
Step-by-step explanation:
Given
--- John number of jog
See attachment of Tyrone's number of jog
Required
Select the true option
From the attached graph, we have:
Calculate the slope (m); i.e. unit rate
For John, we have:
A linear equation is represented as:
Where m represents the unit rate. So, by comparison;
--- John unit rate
--- Tyrone unit rate
<em>Option B is correct because Tyrone's rate is 1 more mile per hour than John's</em>
<em>i.e. 6 - 5 = 1</em>
