4 pizzas because, 12 slices /3 per person =4 and 16 people /4 = 4 pizzas
Answer:
The height between the two trees will be 1.67 feet.
Step-by-step explanation:
What you do is you take the 1/2 have and times it by 6 because it is every two years that the tree grows 1/2 of a foot. So it will be 3 feet. The other tree grew 4 inches in 3 years so it will be 16 inches you will then have to make the 16 inches into feet to get 1 1/3. You will then minus the 3 feet and the 1 1/3 to get 5/3 or 1.67 feet.
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
Answer:
Part 1) The vertex is the point (-83,-9)
Part 2) The focus is the point (-82.75,-9)
Part 3) The directrix is 
Step-by-step explanation:
step 1
Find the vertex
we know that
The equation of a horizontal parabola in the standard form is equal to
where
p≠ 0.
(h,k) is the vertex
(h + p, k) is the focus
x=h-p is the directrix
In this problem we have
Convert to standard form
so
This is a horizontal parabola open to the right
(h,k) is the point (-83,-9)
so
The vertex is the point (-83,-9)
step 2
we have
<em>Find the value of p</em>
<em>Find the focus</em>
(h + p, k) is the focus
substitute
(-83+1/4,-9)
The focus is the point (-82.75,-9)
step 3
Find the directrix
The directrix of a horizontal parabola is
substitute

Answer:
(2 · 10⁰) + (5 · 109)
= (2 · 0) + (5 · 109)
= 2 + (5 · 109)
= 2 + 545
= 547
Your answer is 547.
