Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Answer:
6
Step-by-step explanation:
tan 45 = 6 / x
1 = 6 / x
x = 6
Note :
Tan 45 value = 1
Answer:
Step-by-step explanation:
The diagonals of a rectangle always bisect each other. Therefore, we can set 
:
Answer:

Step-by-step explanation:
A drop in temperature is indicated by - ( negative symbol )
A drop of 2° followed by a drop of 3° is
- 2 + (- 3) = - 2 - 3 = - 5°
the sign of the sum is - ( negative add a negative is negative )
the total change in temperature is - 5°
the sum of 2 positive integers is positive , that is
+ 2 + (+ 3) = + 2 + 3 = = + 5
If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line. Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary. Example: Graph the quadratic inequality.
