The percentage of change from 45 to 56 is 24.4%

A frog is climbing out of a well that is 11 feet deep. The frog can climb 3 feet per hour but then it rests for an hour, during

Dimas [21]

Answer:

It takes the frog 7 hours to get out of the well.

Step-by-step explanation:

We know that the well is 11 feet deep and the frog can climb 3 feet per hour.

Each time it climbs, it rests for an hour, and decreases its height by 1 foot.

So, if the frog reaches 3 feet in the first hour, then in the next hour it is 2 feet.

Lets calculate with the same pattern:

1st hour: 3 feet

2nd hour: $3-1=2$ feet

3rd hour: $2+3=5$ feet

4th hour: $5-1=4$ feet

5th hour: $4 +3= 7$ feet

6th hour: $7-1=6$ feet

5th hour: $6+3=9$ feet

6th hour: $9-1=8$ feet

7th hour: $8+3= 11$ feet

Therefore, it takes the frog 7 hours to get out of the well.

- 6x+4=-2 algebra question

QveST [7]

You need to get x= something.

To do this, you -4 on both sides to leave you with just an x value on the left. This gives -6x=-6

Then you need x on its own, so you divide both sides by -6.

-6/-6= 1, so x=1
