Let s = # of students in the sixth grade. 60% of these, or 0.60s, ate pizza: thus, 0.60s = 36. Solving for s, s = 36/0.60 = 60.
There are 60 students in the sixth grade.
Steps:
1) 50 / .1 = 500
2) 500 * .25 = 125
Answer = 125
Answer:
8 inches
Step-by-step explanation:
The area of a triangle is:
a = 1/2 × b × h
- b = length of the base
- h = height
We can sub in the values we know:
16in² = 1/2 × b × 4in
To find b, we divide both sides by 1/2 and 4in:
16in² ÷ (1/2 × 4in) = b
16in² ÷ 2in = b
b = 8in
Hope this helps!
Answer:
B) 15/91
Step-by-step explanation:
Probability of a girl as first choice is ...
number of girls / total number of students = 6/14 = 3/7
Probability of a girl as second choice (given a girl as first choice) is ...
number of girls / remaining number of students = 5/13
Then the probability of the two events is the product of their individual probabilities:
(3/7)·(5/13) = 15/91 . . . . . matches choice B
