Answer:
Tristan will need 32 feet of material for the perimeter of the garden.
Step-by-step explanation:
Given that
Area of square garden = A = 64 square feet
Perimeter = P = ?
We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.
So,
s is for side
Putting the value of area
Taking square root on both sides
The length of side is 8 feet.
Perimeter will be:
Hence,
Tristan will need 32 feet of material for the perimeter of the garden.
Exponential growth has the form:
F=Ir^t, F=final amount, I=initial amount, r=rate, t=time.
First let's solve for the rate, r, using the points provided...
37325/34560=(Ir^2)/(Ir^1)
r≈1.08
Now find the initial amount...
34560=I(1.08)^1
I=32000 so now we have the entire equation, using x and y...
y=32000(1.08)^x
Let's make an equation.
19,000x=24,320
This equation shows the percentage increase, which is x. Once we have x, we need to subtract 1 from it since in the equation the 1 shows that it's increeasing. All we need to do is divide both sides by 19,000.
24,320÷19,000
1,28-1=0.28; we need to multiply by 100 to find the increase.
0.28×100=28
So, the percentage increase is 28%.
Answer:
4x-2y
Step-by-step explanation:
Answer: Diego has 5 fewer counters.
Step-by-step explanation:
In order to find the answer, you need to find the difference between the amount of counters Dara has compared to Diego.
(Amount Dara has) - (Amount Diego has) = Difference
12 - 7 = 5
Diego has 5 fewer counters
