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.
36 donuts (2 1/2 dozen) = $8.00
So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.
One dozen donuts = $2.64
Number 2 is 7 9/8 but its an improper fraction so you'll have to reduce that since im having trouble doing that.
Number 5 is 9 11/12
Hope this helps!
Answer:
y intercept = 5
Step-by-step explanation:
f(x)=5•(1/6)^x
The y intercept is when x =0
Let x =0
f(0)=5•(1/6)^0
= 5* 1 = 5
The y intercept is 5
If the question is
f(x)=5•(1/6)x
although I have never seen the question written this way
The y intercept is when x =0
Let x =0
f(0)=5•(1/6)0
= 5* 0 = 0
The y intercept is 0
