Answer:
x = 9.7
Step-by-step explanation:
Reference angle (θ) = 68°
Opposite = 24
Adjacent = x
Apply, the trigonometric function, TOA which is:

Plug in the values

Multiply both sides by x

Divide both sides by tan 68

x = 9.69662942
x = 9.7 (nearest tenth)
Answer:
3
Step-by-step explanation:
The common ratio here is 3. Note that 4 is the first term of this sequence, and that n is the index: first term, second term, etc.
Every term is found by mult. the previous term by 3.
This is eazy 630=90x
divide 90 on both sides
7=x
x=in
7feet=1in

Step-by-step explanation:
I like to work problems involving repetitive calculations using a spreadsheet. The sort function can easily put the results in the appropriate order.
__
Here, we need to compute minutes and kilometers remaining for each cyclist, and then divide the former by the latter to find the required timing.
Minutes remaining will be the difference between the qualifying time and the time used so far.
Km remaining will be the difference between the race length and the distance traveled so far.
Required minutes per km will be the ratio of minutes remaining to km remaining.
Levi has the least allowed minutes per km for his remaining distance. Roberto has the most.
_____
Christopher only has to increase his average speed by about 5% in order to qualify; Levi has the greatest challenge, as he needs about 18% more speed for the rest of the race.
