Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,
Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,
cube cm.
⇒ First option is correct.
Answer:
The number of servings of gelatin is 48
Step-by-step explanation:
step 1
Find out the number of molds
Divide the number of packages of gelatin (8) by 1 1/3 to obtain the number of molds
Remember that
so
step 2
Find out the number of servings of gelatin
we know that
Each mold can be divided into 6 servings
To obtain the number of servings multiply the number of molds by 6
therefore
The number of servings of gelatin is 48
You'll need to graph y = (5/3)x + 3 and y = (1/3)x - 3 on the same set of axes. These two lines will intersect. From the graph, determine the coordinates of the point of intersection. The result is the desired solution (x, y).
First of all, are you able to graph these two lines? Secondly, can you read the coordinates of the point of intersection from the graph?
I urge you to try graphing these lines and determining the point of intersection.
Of course there are other ways in which you could solve this problem (if you were to ignore the requirement that you solve it graphically): elimination by substitution, elimination by addition or subtraction.
