Answer:
the first one is D and the second is C
Step-by-step explanation:
this is because a trapezoid has one length that is longer than the other, so the bottom of the trapezoid is longer than the top in this case
Since there are 14 boys and the whole class has 31 students
We get, the ratio of the part-to-whole relationship for boys is 14/31.
And since there are 17 girls
We get, the ratio of the part-to-whole relationship for girls is 17/31.
The percent of change will be a percentage increase because we go from a smaller number to a larger number. To find a percentage increase, we will use the percentage increase formula:
% increase = final value - original value / original value x 100
Substituting the values in:
% increase = (8,200) - (7,500) / 7,500 x 100, where 8,200 is the new value and 7,500 is the original value.
Simplification after multiplication: 700 / 7,500 x 100
Simplification after division: 0.093 x 100
Simplification after multiplication of 100: 9.333%.
We can round 9.333% down to 9%.
