We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
Answer:
Choice B
Step-by-step explanation:
Divide both of the choices by the price and ounces. You will find that the unit rate of choice B is lower.
Work
3.49/25=0.14
4.79/45=0.106
Therefore choice B has the lowest unit rate and that is the answer!
Answer:
y = 
Step-by-step explanation:
Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.
Let the number of gallons of white paint required = x
and number of gallons of red paint required = y
y ∝ x
y = kx [k = proportionality constant]
Since a point (4, 1) lies on this line,
1 = 4k
k = 
Therefore, equation that describes the relationship will be,
y = 
Answer:
Step-by-step explanation:
<u>Co-planer</u>
When points are in the same plane it means that the points are co-planer.
