Answer:
64 cm²
Step-by-step explanation:
(12*4.5)+(2*5)= 54+10=64
Answer:
Step-by-step explanation:
Similar figures have the same shape but the same size.
Moving from left to right:
The first figure is similar because it is rotated
The second figure is not similar because of shape
The third figure is not similar because of different ratio the ratio for the figure above is 3/5 or 0.6, while this figure is 12/15 or 0.8
The fourth figure is not similar because of ratio, but it is still a rectangle
The fifth figure is not similar because of shape
The last figure is similar because the ratio is the same with 6/10 or 0.6
Answer:
8x + 16y = 39 and
40x + 8y = 42
Step-by-step explanation:
Let the length of the blue tiles is b inches and that of the white tiles is w inches.
So, given that a row of 8 blue tiles and 16 white tiles has a length of 39 inches and a row of 40 blue tiles and 8 white tiles has a length of 42 inches.
Therefore, we can write the system of linear equations that represents the relationship between the length if a blue tile and a white tile in inches as
8x + 16y = 39 and
40x + 8y = 42 (Answer)
Answer:
the answer is the first one
Step-by-step explanation:
39.99 rounded up is 40.00
19.99 rounded up is 20.00
40.00*0.05 = 2, 40-2 = 38
20.00*0.15 = 3, 20-3 = 17*.05 = 0.85, 17-0.85 = 16.15
38+16.15 = 54.15
Answer:
x+y≤14
10x+5y>100
