Answer:
The width of the football field is 160 feet.
The length of the football field is 360 feet.
Step-by-step explanation:
Let w represent width of the football field.
We have been given that the length is 200 ft more than the width, so the length of the field would be 
.
We are also told that the perimeter is 1,040 ft. We know that football field is in form of rectangle, so perimeter of field would be 1 times the sum of length and width. We can represent this information in an equation as:
Let us solve for w.
Therefore, the width of the football field is 160 feet.
Upon substituting in expression , we will get length of field as:
Therefore, the length of the football field is 360 feet.
Answer:
The factors of 8 are 1,2,4, and 8.
Step-by-step explanation:
Answer:
a = 10
Step-by-step explanation:
From the solution given, x = a and y = -1
Substitute for x and y in either of the equations
y = -x + 9
-1 = -a + 9
a = 9 + 1 = 10
Step-by-step explanation:
1. 3.81 = 3.8 because 8 is in the tenths place and you rounded it. 1 is less than 5 so the number stays the same.
2. 72.27 = 72.3 because 2 was in the tenths place and you rounded it by 7. 7 is more than 5 so the number changes to 3.
The number beside the number you want to round on the left must be equal or more than 5.
3. 167.79 = 167.8 4. 67.04 = 67 5. 1.356 = 1.36 6. 0.048 = 0.05
7. 8.333 = 8.33 8. 1.9973 = 2 9. 7.4 = 7 10. 171.68 = 172
11. 0.0018 = 0 12. 600.55 = 601
