Tan =opposite/adjacent
opposite = y
adjacent = 15
tan = 26.5
rearrange the fomula to make:
opposite = tan × 15 (or tan26.5* 15)
y = 7.47 or rounded to 7.5ft
Plan A: 30 + 0.01m
Plan B: 20 + 0.05m
in order for 2 plans cost the same, both need to be equal
so should be
20 + 0.05m = 30 + 0.01m
answer is D. last one
20 + 0.05m = 30 + 0.01m
dogs to cats means 4 dogs for every 6 cats
if there are 36 cats. divide that by 6
36/6 = 6 then multiply that by 4 so 6*4 = 24
so 24 dogs
So basically when you are adding or subtracting fractions the denominators the number on the bottom of the fraction 12 in this case and 8 as well the two denominators sharing the least common multiple so what is the lowest multiple of 12 and 8 so count off 12: 12, 24, 36... 8: 8, 16 , 24 does that help?
