Answer:
1 hour and 15 minutes
Step-by-step explanation:
Nuala drives 20 miles per hour, which makes the trip 2 hours and 30 minutes long. If Nuala drove at 40 miles per hour, the trip would take 1 hour and 15 minutes. Why? Because:
40 miles per hour
50 miles- 40 miles=10 miles (that makes 1 hour already)
so now we figure out how long it takes for 10 miles at the speed of 40 miles per hour.
10/40=1/4 and 1/4 of an hour or 60 minutes is 15 minutes.
Therefore, it would take Nuala 1 hour and 15 minutes if she drove 40 miles per hour.
Hope this helped!
First find the slope by calculating rise (change in x) over run (change in y).
(4/5)-0/0-(-5)
(4/5)/5=0.16
The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.
Then plug this into y=mx+b where m is slope andb is y intercept.
Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5
Answer:
Which question and can it be more clear
Step-by-step explanation:
Answer:
the area is 68 feet
Step-by-step explanation:
-first pretend that one spot is filled and if you do that the whole rectangle is 8 by 10.
- the area of something is length times width and so 8 times 10 is 80
- however, we can't pretend that we don't have a hole anymore so to figure out that tiny rectangles area we have to find its width and length which is 4 and 3.
- 4 times 3 is 12 and since we have that we subtract 12 from 80 and we get 68.
If you mean:
1/(3a^2)-1/a=1/(6a^2) we need a common denominator of 6a^2
2/(6a^2)-6a/(6a^2)=1/(6a^2), multiplying all terms by 6a^2 then:
2-6a=1 subtract 2 from both sides
-6a=-1 divide both sides by -6
a=1/6
