Answer:
it is 84
Step-by-step explanation:
the least common multiple of 7 and 12 is 84. i have no step by step explanation...sorry
You can find the LCM by listing the multiple for each factor.
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84
12, 24, 36, 48, 60, 72, 84
Is this case, the factor 84 is the LCM
Hope this helps!!!
21..........
None, the answer will be the same
8/15
4/5 times 2/3
7.96 ft
Given;
Length of ramp L = 8 ft
Angle with the horizontal (ground) = 6°
Applying trigonometry;
With the length of ramp as the hypothenuse,
The horizontal distance d as the adjacent to angle 6°
Since we want to calculate the adjacent and we have the hypothenuse and the angle. We can apply cosine;
Cosθ = adjacent/hypothenuse
Substituting the values;
Cos6° = d/8
d = 8cos6°
d = 7.956175162946
d = 7.96 ft
The building is 7.96ft away from the entry point of the ramp.
