Looking at the predicted three terms, the sequence seems to neither arithmetic nor geometric.<span />
-3x + 4 = 2x - 1
5x = 5
x = 1
When x = 1, y = 1
I'm not sure about the graph, but I solved them simultaneously? If you meant which graph but forgot to upload a photo attachment, look where it crosses the Y axis. If it is 4, it will be the first equation, if it crosses at -1, it will be the second equation
Answer:
She needs 301.8 in² of tissue paper.
Step-by-step explanation:
In order to calculate the amount of tissue paper she needs to make 21 hats, we need to find the area of each hat and multiply it by the total number of hats she wants to make.
Since the Vietnamese conical hats are hollow and don't have a base, we need to find the area of the it's lateral walls, this is given by the following expression:
lateral area = pi*r*l
r = d/2 = 16/2 = 8 in
We were given the height, but we need the slant height, therefore:
l = sqrt(r² + h²) = sqrt(8² + 9²) = sqrt(64 + 81) = sqrt(145) = 12.041 in
Then the lateral area is:
lateral area = pi*8*12.0141 = 301.8 in²
She needs 301.8 in² of tissue paper.
Answer:
It's 10,920 ( E)
Step-by-step explanation:
1 hr = 60 mins
7 hrs = 60 × 7
7 hrs = 420 mins
if they package 26 cases per minute,
they would package 420 × 26 in 7 hours
i.e they'd package 10920 cases in 7 hours
