F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
Answer:
4 cm ×12 cm
Step-by-step explanation:
To find the dimensions of the sticker, start by forming 2 equations for its area and perimeter.
Perimeter of rectangle= 2(length +breadth)
Let the length and breadth of the rectangle be L and B cm respectively.
2(L +B)= 32
Divide both sides by 2:
L +B= 16 -----(1)
Area of rectangle= length ×breadth
LB= 48 -----(2)
From (1): L= 16 -B -----(3)
Substitute (3) into (2):
(16 -B)(B)= 48
Expand:
16B -B²= 48
B² -16B +48= 0
(B -4)(B -12)= 0
B -4= 0 or B -12= 0
B= 4 or B= 12
Substitute into (3):
L= 16 -4 or L= 16 -12
L= 12 or L= 4
Thus, the dimensions of the sticker is 4 cm ×12 cm.
Step-by-step explanation:
This ≤ inequality sign means:
- Less than/Equal to
- No more than
- At most
- Maximum of
-5 ≤ 4
And then:
-3x ≤ 2
OR:
-5 ≤ 4 -3x ≤ 2
Hi!!! Sorry, I didn't know if they were suppose to be together or separate, so I just did it both ways!!! :) Really sorry if I am wrong...
Here is how you solve this:
1) If a line bisects an angle, then both angles are equal (This means that angle OLN and angle OLM are equal).
2) If 2 angles of 2 triangles are equal, then the sides opposite of each angle are equal (This means that, since angle OLN and angle OLM are equal, side NO and side OM are equal).
3) If NO=OM, then OM=4.
The answer is x=4.
Answer:
Trees can help stop erosion by managing runoff. Their leaf canopies help reduce erosion caused by falling rain. They also provide surface area where rain water lands and evaporates. Roots take up water and help create conditions in the soil that promote infiltration.
