Answer:
The percent error of the length of the soccer field is 1.4%
Step-by-step explanation:
Actual length of soccer field = 500 feet
Length shown in measuring instrument = 493 feet
We need to find the percent error of the length of the soccer field.
The formula used to find percent error of the length of the soccer field is: 
The exact length = 500
Approximate length = 493
Putting values and finding percent error

So, the percent error of the length of the soccer field is 1.4%
Answer:
x = 13
Step-by-step explanation:
5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.
Then 5x + 25 = 7x - 1, and
25 = 2x - 1, and so 2x = 26 and x = 13
Answer:
11
Step-by-step explanation:
- 9+3(8-3(7-5))-4
- 9+3(8-3(2))-4
- 9+3(8-6)-4
- 9+3(2)-4
- 9+6-4
- 15-4
- 11
I first delt with simplifying the parentheses till step five. Then in five I just added 9+6 because it came before the -4. But PEMDAS is very important when doing these problems because it tell you the order
- P (parentheses)
- E (exponents)
- M (multiply)
- D (divide)
- A (add)
- S (subtract)
- **the biggest thing is that with multipe and divide it depends what comes first. If you see divide before multipe in the problem just do it that way. It is the same way with add and subtract but The multiple/divide group ALWAYS comes BEFORE add/subtract
