all the answer choices are correct
Step-by-step explanation:
reflections & rotations dont change any of the angle measures
A dime is a ten cent coin while a quarter is a 25 cent coin. The total of the money should be $8.40. Let x be the number of dime and y be the number of quarter. The equation that would best represent the given problem is,
0.1x + 0.25y = 8.40
x + y = 45
The values of x and y are 19 and 26, respectively. Thus, there are 19 dimes and 26 quarters.
P = 2(L + W)
160 = 2(50 + W)
160 = 100 + 2W
160 - 100 = 2W
60 = 2W
60/2 = W
30 = W
so length is 50 and width is 30
A = LW
A = (50)(30)
A = 1500 ft^2 <===
