A)
The percent of students with a curfew is:
number of students with a curfew/total students*100
The number of students with a curfew is 37+33=70 students. It says in the problem that the total is 125.
70/125*100=0.56*100=56%
56% of students have a curfew.
b)
The percent of students without chores is:
number of students without chores/total students*100
The number of students without chores is 27+33=60 students. It says in the problem that the total is 125.
60/125*100=0.48*100=48%
48% of students are without chores.
c)
Look across the chart. Only 33 students for the description.
33/125*100=0.264*100=26.4%
d) The only answer possible is the second choice.
Good luck!
Answer:
10 and 2/7
Step-by-step explanation:
7/6 = 1 1/6

Answer:
247 yd²
Step-by-step explanation:
this figure can be "split" into 3 sub-figures.
2 rectangles and one triangle "at the top".
these 3 areas can be easily calculated, and the we simply sum them all up, and that is the total area.
my approach is to pick the first rectangle to be the one extruding one to the right.
R1 = 11×5 = 55 yd²
the second rectangle is then the rest of the"straight" area up to the beginning of the triangle top
R2 = 8 × (13+5) = 8×18 = 144 yd²
and the area of a triangle is
baseline × height / 2
we can clearly see in our example, it is a right-angled triangle, so the left side is also the height, which is the remainder of the long side of the original figure, when we deduct all the other parts we used for the rectangles.
so, we have
T = 8 × (30 - 5 - 13) / 2 = 8×12/2 = 8×6 = 48 yd²
so, in total we have
F = 55 + 144 + 48 = 247 yd²
1+3=4
A counterexample is an a example that proves the statement false.
1+3 are not even numbers but they equal an even one, so it just proved the statement wrong.
