You would take 1818÷33=55.09

55.09 is how many toothpicks it took for each step made

Then you would take 55.09×55=3029.95

You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up

To answer this we will do the following:-

1818 ÷ 33 ≈ <span>55.09
55.09 toothpicks per stair. 

55.09 </span>× 55 = <span>3029.95

So, to build a 55-step stair case Ann will need</span> ABOUT 3029.95 tooth <span>picks.

Hope I helped ya!! </span>

makvit [3.9K]

Answer:

The correct answer is C= $99.400

Step-by-step explanation:

You need to sum all he has and then rest all he owes

The car has a balance of 20000 owed so 38000-20000=$18000 to sum

%195000+$5000+$1400+$180000=$219400

Then you rest what he owes= $219400-$120000=$99400

Thats Ben's net worth

The Answer is C=$99400

The car has a balance of 20000 owed so 38000-20000=$18000 to sum

How do you find the vertex and axis of symmetry for this function, <br><br> F(x)=3(x+1)^2
Andrews [41]
Answers:
Vertex is (-1,0)
Axis of symmetry is x = -1

============================================

Explanation:

F(x) = 3(x+1)^2
is the same as
y = 3(x-(-1))^2 + 0
which is in the form
y = a(x-h)^2 + k

We can see that
a = 3
h = -1
k = 0

Therefore the vertex is (h,k) = (-1,0)
The axis of symmetry is x = h = -1 which is the equation x = -1

The axis of symmetry in this case is a vertical line through the vertex.
