Explanation:
- 9 feet
- 10 feet (10 ft = 10·12 in = 120 in)
- 130 inches
- 12 feet (12 ft = 12·12 in = 144 in)
- 145 inches
_____
Obviously, 9 < 10 < 12, so ordering by feet is easy. Then we need to figure out where the inch measurements belong.
1 foot = 12 inches, so we can figure some references to use to compare to the inch measurements.
10 feet = 10·12 in = 120 in, so 130 in is longer, by less than 1 ft.
12 feet = 12·12 in = 144 in, so 145 in is longer.
Answer:
2 and 3
Step-by-step explanation:
20/12 = 1.6666666
15/9 = 1.6666666
The slope is 1/4, so only choices B, D, E are worth considering. Only choices D and E have the correct point in the point-slope form.
The appropriate selections are
D. y -4 = (1/4)(x -4)
E. y -6 = (1/4)(x -12)
Answer:
32
Step-by-step explanation:
80/2 = 40
64/2 = 32
so she can make about 32
