Levant will receive about 9 american dollars when he exchanges his pesos.
According to this question, 1 american dollar is worth about 11 pesos. In order to find that, you need to divide 3000/270 which gives you around 11. In order to find out how many dollars he will receive for his pesos, you need to divide 100 by 11 which gives you about 9 dollars.
When purchased for 6.19, after mark up +4.20 = $10.39
The average rate of change of the function from x = 0 to x = 2 is -2
From the complete question (see attachment), we have the following ordered pair when x = 0 and x = 2

The average rate of change is calculated using:

So, we have:

Evaluate common terms

Divide -4 by 2

Hence, the average rate of change of the function from x = 0 to x = 2 is -2

Answer:
b = infinity
Step-by-step explanation:
1 − 3(3 + 6b) = −6(3b + 1) − 2
1 - 9 - 18b = -18b + 1 -2
1 - 9 = 1 - 2
-8 = -1
Answer:
Length = 15 cm, width = 12 cm, Perimeter = 54 cm
Step-by-step explanation:
The ratio of the length and breadth of a rectangle is 5:4 and its area is 180 cm².
Length = 5x
Breadth = 4x
Area of rectagle,
A = bl
180 = 5x × 4x
180 = 20x²
x² = 9
x = 3
Length = 5x = 5(3) = 15 cm
Width = 4x = 4(3) = 12 cm
Perimeter of rectangel,
P = 2(l+b)
= 2(15+12)
= 54 cm
Hence, this is the required solution.
