5 + 5 + 10 = 20
x + y + z = 160
5 × 80 : 5 × 80 : 10 × 80
400 : 400 : 800
If they're travelling towards each other;
Effective speed = 75+55 = 130
Distance = 338m
Time= distance/ speed
T= 338/130
T= 2.6 hrs
The statement that explains how the company can determine whether pool LMNO is similar to pool PQRS is;
B. Translate PQRS so that point Q of PQRS lies on point M of LMNO, then dilate PQRS by the ratio segment PQ over segment LM.
<h3>How to carry out Transformations?</h3>
Given that quadrilaterals ABCD and EFGH are similar:
The corresponding points on the quadrilaterals are:
P → L
Q → M
R → N
S → O
So, the first step is any of the following:
Translate point P to L
Translate point Q to M
Translate point R to N
Translate point S to O
Notice that the side lengths of PQRS are bigger than that of LMNO
This means that the Quadrilateral PQRS has to be dilated (compressed) by a ratio of side lengths of LMNO divided by side lengths of PQRS
For example, the point M is translated to point Q. The figure will then be dilated by a ratio of LM divided by PQ.

Step-by-step explanation:
<u>Part a</u>
P(x) = 0
150x - x^2 = 0
x(150-x)
x=0,150
Laura should sell 150 pies in order to "break-even" on her sales.
<u>Part b</u>
Because the maximum profit occurs at the vertex of the function,
x = -b/2a = -150/-2 = 75
P(75) = 150 * 75 - 75^2 = 5625
Laura maximizes her profit to $5625 when she sells exactly 75 pies.
