Complete question is;
In a race that consisted of three parts, the cycling part was 12 1/2 miles long. The running part of the race was 1/4 the distance of the cycling part. The kayaking part of the race was 1/2 the distance of the running part. What was the entire distance, in miles of the race?
Answer:
Total distance of race = 17.1875 miles
Step-by-step explanation:
The 3 parts of the race are; cycling, running and kayaking.
The cycling distance was; 12½ miles
We are told that the running part was ¼ of the cycling distance. Thus;
Running distance = ¼ x 12½ = ¼ x 25/2 = 25/8 miles
Lastly, we are told that the kayaking part was ½ the distance of the running part. Thus;
Kayaking distance = ½ x 25/8 = 25/16
Thus,total distance of race = cycling distance + running distance + kayaking distance = 12½ + 25/8 + 25/16 = 17.1875 miles
Answer:
So I', just guessing you are solving for why.
y=5+2x
Step-by-step explanation:
Basically you move all the numbers that don't have why on to the other side of the equation and vice versa if you are solving for x.
X=40
Complementary=90 degrees
50+x=90
-50 -50
X=40
<u>Answer:</u>
The number of ways can you win first prize and your mom win second is 1/56 ways.
<u>Step-by-step explanation:</u>
Total number of people entered the contest= 8 people
Total number of prices awarded=3 prizes
Therefore the total number of ways in which 3 prizes can be awarded = 8*7*6 = 336 ways
The number of ways in which you can win first prize and your monm can win the second prize is =1*1*6 = 6 ways
So,by probability to find the ways with which you can win the first prize and mom can win the second prize can be calculated as = 6/336 = 1/56
Cos can not be greater than 1 therefore it’s not possible
