Answer:
Jeff got 20 answers right.
Step-by-step explanation:
The maximum number of points Jeff can get is 100. (25 * 4) However, for each question he gets wrong, he's actually losing 6 points because he doesn't get the four points for getting right, and has the additional -2 points for getting it wrong. Since he only got a score of 70, that means he lost 30 points.
30/6 = 5. So he missed 5 question and got 20 question right.
Answer:
30
Step-by-step explanation:
What you need to do is add all the sides when you want to find perimeter so for this one you would want to do 8+8+7+7 and that should give you 30. I hope I could help!!
If you write .6 and .7 as fractions you get 6/10 and 7/10. If you double those you get 12/20 and 14/20, so one potential fraction between the two could be 13/20.
f(x)=0
Domain are the set of x values
f(x)=0 , we find all the x values where y =0
At x intercepts y is always 0
so we find all the x intercepts.
x intercepts are the points where the graph crosses x axis
In the graph we can see that the graph crosses x axis at
-2.5 , -0.75 and 1
-2.5 , -0.75 and 1 are the domain where f(x)=0
Answer:
Step-by-step explanation:
<u>Given</u>
a)
- DC /AB = 3/2 ⇒
- DC = 3/2AB = 3/2p
b)
- BC = AD + (DC - AB)
- BC = q + (3/2p - p) = q + 1/2p
