Answer:
125.97
Step-by-step explanation:
We’ll start by the cone
We first have to know how to calculate the volume of a cone
V = pi(r^2)(h)/3 where r = radius & h = height
But since we’re only seeing a diameter of 6 cm in the bottom of the cone, we’ll need to divided 6 by 2
Radius = 3
Then we can start solving for the volume of the cone!
V = pi(3^2)(7)/3
V = pi(9)(7)/3
V = pi(63)/3
V = 197.82…/3
V = 65.97
The volume of the cone is approximately 66 cm
Now for the Rectangular Prism:
V = l • w • h where l = length w = width and h = height
V = 12 • 5 • 1
V = 60 • 1
V = 60
Finally add each of the volumes!
65.97 + 60 = 125.97
The volume of the object is approximately 126 cm
If the 20 fl.oz bottle contains 125% of the next smallest size, the next smallest bottle should be 4/5 of the 20fl. oz bottle.
That means the smaller bottle has 16 fl. oz (you can check it, multiply 16 by 1.25 and you get 20).
Next, you can find the price as dollars per fluid ounce.
The bigger bottle will be: 5.8/20=$0.29
The smaller bottle: 5.12/16=$0.32
In this case, the larger bottle is the better buy because you pay less per fluid ounce of lotion.

12
Step-by-step explanation:
3r = 36
3r/3 = 36/3
r = 12
Answer:
D(-1,0)
Step-by-step explanation:
Plot points A(-3, 2), B(-1, 4), and C(1, 2) on the coordinate plane (see attached diagram).
Two sides AB and BC are of equal length and are perpendicular, because
If the quadrilateral ABCD has all sides perpendicular, then ABCD is a square. The diagonals of the square bisects each other. Find the coordinates of the point of intersection of these diagonals. This is the midpoint of segment AC:
If point O(-1,2) is the point of intersection of diagonals, then it is the midpoint of the diagonal BD. Find coordinates of point D:
Thus, D(-1,0)
