Answer:
57 questions correct
Step-by-step explanation:
95% of 60 is 57
3x + 3y + 6z = 9
2x + 1y + 3z = 7 ⇒ 6x + 6y + 8z = 6
1x + 2y - 1z = -10 6x + 6y + 8z = 6
4z = 12
3x + 3y + 6z = 9 4 4
2x + 1y + 3z = 7 ⇒ 0x + 0y + 4z = 12 z = 3
1x + 2y - 1z = -10 2x + y = -2
2x + (-4) = -2
2x - 4 = -2
+ 4 + 4
2x = 2
2 2
x = 1
(x, y, z) = (1, -4, 3)
Pitch = rise/span = rise/(2 x run)
5/11 = rise/(2 x 33) = rise / 66
rise = 66 x 5/11 = 30 feet.
Answer:
19.5 cm wide
36 cm tall
Step-by-step explanation:
The given, 3 cm : 2 ft, is your first fraction (3 cm / 2 ft). We need to figure out how many cm is 13 ft and 24 ft. Let's start with 13 ft. We would use the first fraction, 3 cm / 2 ft, is equal to x cm / 13 ft. Then, you would cross multiply and get an answer of 19.5 cm. Now, we do the same thing but instead of 13 ft we need to use 24 ft. So again, 3 cm / 2 ft is equal to x cm / 24 ft. Then, cross multiply and get a final answer of 36 cm.
