Her average now is 88.
She needs to bring it up to a 90.
Let's start with if she gets a 90.
88 + 90 = 178
178/2 = 89
A 90 would only get her an average of 89, so you need to go higher.
88 + 91 = 179
179/2 = 89.5
88 + 92 = 180
180/2 = 90
She must get at least a 92 to get an average of 90.
first bar: 4(high),21(across)
second bar: 9(high),22(across)
third bar: 12(high),14(across)
so let's firstly find the component form of "u", keeping in mind that "v" is really in the opposite direction and twice as long, so v = -2u.
1) Which of the following is an example of a dilation?
The correct answer is A) The hearts.
2) If triangle ABC is reflected across line m, the new coordinates will be located at A'(2, -4) B'(7,-7) C'(-2, -7).
The answer is False.
I hope this helps! I can't really see #3. Sorry. But I got #'s 1 & 2 though!
