9/10 - 5/10
because the denominators are the same you keep it and just subtract the numerators
=4/10
This can be reduced to 2/5
Answer:
EF ≈ 1.98
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = 
= 
= 
( multiply both sides by 4.5 )
4.5 × sin26° = EF
4.5 × 0.44 = EF , that is
EF ≈ 1.98 ( to 2 dec. places )
Answer:
Step-by-step explanation:
Subtract 3 from both sides:
Subtract 10x from both sides:
Divide both sides by -3:
-x represents the length of the trouts that can NOT be kept
-Less than ten inches long
x<10
Answer:
All we have to find the fraction of students who preferred green and go from there.
Subtracting blue and red out of the all students,
1- (1/8+1/4)
1- 3/8
5/8 is the remaining students, in order to find 3/5 of the remaining students, we multiply by 3/5
5/8(2/5) = 3/8
3/8 preferred green, which was 15 students. In order to get 100% of the whole population (1), we multiply by 8/3:
15(8/3) = 40
40 students were surveyed in total.
