Answer:
Numbers of pitchers of lemonade = 8
Step-by-step explanation:
Given as
Amount of lemonade concentration = of a cup
Now, of a cup of concentration mix with
of water
So, -
=
of cup of lemonade,
∴ The number of small pitcher of lemonade =
= 4 × 2 = 8 Answer
Answer:
A,C,D
Step-by-step explanation:
Complete Question:
<em>"Which pairs of points would result in a line with a rate of change of 2:1? select all that apply"</em>
<em>A.(−4,−11) and (−2−7) </em>
<em>B.(5,6) and (−5, 12) </em>
<em>C.(0,−3)and (−4,−11) </em>
<em>D. (0,−3) and (5, 7)</em>
<em />
Rate of change is the slope. 2:1 would mean a slope of simply, 2.
We need to find slope of each of the choices from A - D and see which one has 2. The formula would be:
Where m is the slope and
x_1 is first x point
x_2 is second x point
y_1 is first y point
y_2 is second y point
Let's calculate slope of each of the choices.
A.
THis one is okay.
B.
THis one is not 2:1.
C.
THis one is okay.
D.
This one is okay.
Hence, A, C, and D all have rate of change of 2:1
