I would go with c. It looks like point b is where the right triangle is
Answer:
The first one is B. 11.75
The second one is A. 4
Step-by-step explanation:
In order to find how many liters (L) of paint he used you need to do 2.5*5.5=13.75 Then to find out how much he has left you do 25-13.75=11.75 So your answer is 11.75.
The second one you have to do the reverse. So since it says 4*_=48, you do 48÷4=_=12. Then since it says 12*1/3=_ You can do 12÷3=_=4 So your answer is 4.
Answer:
Step-by-step explanation:
y=ax^2+bx+c
when x=0,y=7 so c=7
when x=3 then y=a*3^2+b*3+7=-2
9a+3b+7=-2
9a+3b=-2-7
9a+3b=-9
V(3,-2)
3=-b/2a
-b=3*2a
b=-6a
9a+3*(-6a)=-9
9a-18a=-9
-9a=-9
a=1
b=-6*1
b=-6a
b=-6
so y=x^2-6x+7
I think f^-1(x)= 3/28 + x/4
Answer:
2 cake donuts
Step-by-step explanation:
This is a question on probability, which means that we can find:
<em> # of wanted outcomes/total outcomes</em>.
Wanted outcomes: Vicky ate 3 cake donuts, so our value is 3.
Total outcomes: Vickey ate 3 + 4 + 8 = 15 donuts, so our value is 15.
Plug in: <em>3/15</em>
Simplify: <em>1/5</em>
So <em>1/5 of donuts Vicky eats will probably be cake donuts</em>.
1/5 * 10 = 2
