Answer:
a) never true
Step-by-step explanation:
a radius is always half of a diameter
Answer:
87 packages
Step-by-step explanation:
First we need to find the volume of the cone-shaped vase.
The volume of a cone is given by:
V_cone = (1/3) * pi * radius^2 * height
With a radius of 9 cm and a height of 28 cm, we have:
V_cone = (1/3) * pi * 9^2 * 28 = 2375.044 cm3
Each package of sand is a cube with side length of 3 cm, so its volume is:
V_cube = 3^3 = 27 cm3
Now, to know how many packages the artist can use without making the vase overflow, we just need to divide the volume of the cone by the volume of the cube:
V_cone / V_cube = 2375.044 / 27 = 87.9646 packages
So we can use 87 packages (if we use 88 cubes, the vase would overflow)
Answer:
For the first one the answer is:
<K = 31°
Sorry I don't know the second one.
Answer:
The pair (5, 3) means x or the pounds of cabbage is 5 and y or 3 is the dollars
So 5 pounds of cabbage costs $3
Cabbage is $0.60/pound
10,6 means 10 pounds of cabbage costs $6.
Step-by-step explanation:
Just divide the $3 by the 5 pounds of cabbage to get $.60 for each cabbage.
