Answer:
60 m wide and 110 m long
Step-by-step explanation:
The more the shape deviates from a square, the smaller the area will be. The area can be reduced by making the park longer and narrower. The sum of length and width must remain the same for the perimeter to be unchanged.
Given park: 70 m × 100 m = 7000 m²
Smaller park: 60 m × 110 m = 6600 m² -- less area than 7000 m²

i am unsure about 3 & 4, i am sorry :(
Answer: 40
<u>Step-by-step explanation:</u>
Let x represent the original ratio and y represent the final ratio:
Egg : Tuna
2x 3x
<u> </u> <u> +15 </u> <em>15 tuna were added</em>
2x = y 3x + 15 = 3y <em>y and 3y are the final 1:3 ratio</em>
Now you have a system of equations. I am going to choose the substitution method. "2x" can be substituted for "y" in the second equation:
3x + 15 = 3y
3x + 15 = 3(2x)
3x + 15 = 6x
15 = 3x
5 = x
Egg (final): 2x = 2(5) = 10
Tuna (final): 3x + 15 = 3(5) + 15 = 15 + 15 = 30
Egg (final) + Tuna (final) = Total sandwiches
10 + 30 = 40
Answer:
6
Step-by-step explanation:
2 to the power of 1 is 2, anything to the power of one is the original number itself. 3*2=6
