Answer:

7.5

Step-by-step explanation:

Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:

Hours        Dollars

0                 25 = 25 + 0(20)=25

1                  25+20 = 25 + 1(20)=45

2                  25+20+20 = 25 +2 (20)=65

3                  25+20+20+20 = 25 +3 (20)=85

4                  25+20+20+20+20 = 25 +4 (20)=105

5                  25+20+20+20+20+20 = 25 +5 (20)=125

 

n                  25+n(20)=175

To find how many hours he worked for $175 we solve the equation using inverse operations:

25+n(20)=175

25-25+n(20)=175-25

n(20)=150

n= 7.5 hours

Can someone please help me on this table?
kiruha [24]

Answer:

Step-by-step explanation:

Given expression which gives the distance is 16t².

Here, t = time or duration

For t = 20 seconds,

16t² = 16(20)²

      = 6400 feet

For t = 21 seconds,

16t² = 16(21)²

      = 7056 feet

For t = 22 seconds,

16t² = 16(22)²

      = 7744 feet

For t = 23 seconds,

16t² = 16(23)²

      = 8464 feet

Therefore, complete table will be,

t             20            21           22           23

h         6400       7056       7744     8464
