If a bike travels 5 miles in 20 minutes, how long does it take to travel 25 miles?

faust18 [17]

Answer:

100 minutes

Step-by-step explanation:

To solve this, we can make a proportion.

The bike travels 5 miles in 20 minutes, and 25 miles in x minutes

5/20=25/x

Cross multiply

5*x=20*25

5x=500

Divide both sides by 5. This will cancel out the 5, and leave x by itself.

5x/5=500/5

x=100

There are 60 minutes in 1 hour. If we subtract 60 from 100,

100-60=40

So, this is also equivalent to 1 hour and 40 minutes.

It takes 100 minutes, or 1 hour and 40 minutes, to travel 25 miles.

Hey! I would appreciate some help with this

arsen [322]

Answer:

...

Step-by-step explanation:

since they give us the side opposite of the given angle(Opposite) and we are trying to find for a (Adjacent/side), so we use TOA

tan(30)= $\frac{4}{a}$

i see u dont want it solved but ill solve it anyways

since a is on the bottom then lets switch them

$x=\frac{4}{tan30}$

x= 6.928

Tickets to a local circus cost $5 for students and $8 for adults. A group of 9 people spent a total of $60. How many adults were

S_A_V [24]

Answer:

Step-by-step explanation:

You need to set up and solve a system of linear equations here.

Let s and a represent the number of students and adults respectively.

Then s + a = 9, and s = 9 - a.

Total ticket cost for the adults was ($8/adult)(a)

and for the students ($5/student)(s).

Total cost of the tickets was then ($8/adult)(a) + ($5/student)(s) = $60.

Then our system of linear equations is:

8a + 5s = 60

a + s = 9, or s = 9 - a. Substituting 9 - a for s, we get:

8a + 5(9 - a) = 60.

Then 8a + 45 - 5a = 60, or 3a = 15.

Solving for a, we get a = 5.

Solving for s using s = 9 - a, we get s = 9 - 5, or s = 4.

There were 5 adults in the group (and 4 students).
