Answer:
Step-by-step explanation:
If there are 90 students and the ratio of boys to girls is 3:2, that means 3x+2x=90
Combine like terms: 5x=90
x=18
2x (girls)=36
3x (boys)=54
1/3 of the boys scored full marks, so 54/3=18 boys scored full marks
The number of girls who scored full marks is half of the number who did not score full marks means that 1/3 of the girls scored full marks. 36/3=12, so 12 girls scored full marks.
(I don't know what the question is sorry if it's incorrect but there's not enough information)

Answer:
12.5 percent increase
Step-by-step explanation:
so we know from 48 oz to 54 oz, the amount increases by 6 oz
now we just have to determine 6 oz is what percentage of 48 oz
6 goes into 48 eight times
100 divided by 8 is 12.5
6 is 12.5 percent of 48
we can double-check this by multiplying 12.5 x 8 which equals 100 so that confirms its 12.5 percent
we get the 8 by seeing that 6 goes into 48 eight times.
if this is confusing comment below and i'll try to clarify
Answer:
where the dots are
Step-by-step explanation:
Two or more lines are parallel when they lie in the same plane and never intersect. The symbol for parallel is <span>||</span>. To mark lines parallel, draw arrows <span>(>)</span> on each parallel line. If there are more than one pair of parallel lines, use two arrows <span>(<span>>></span>)</span> for the second pair. The two lines below would be labeled <span><span><span>AB</span><span>←→</span></span> || <span><span>MN</span><span>←→−</span></span></span> or <span>l || m</span>.
For a line and a point not on the line, there is exactly one line parallel to this line through the point. There are infinitely many lines that pass through A, but only one is parallel to l.
