Answer:
last year 100 boys and 60 girls, for a total of 160.
this year, 120 boys and 75 girls, for a total of 195.
35 more than 160 is a 21.8% increase
Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
1. Let's check the problem backwards. So let's map A"B"C" to ABC
2. We first need to reflect A"B"C" to A"B"C' with A"B"" as the axis of rotation.
3. Then we shift a few units up (translation) A"B"C' to A'B'C
4. Finally we rotate A'B'C around C to map the triangle onto ABC
going backwards we get the answer: b
