310 / 10 = 31.
31 x 12 = 372 feet.
That is one fast elevator
Answer:372
Step-by-step explanation:
310/10=31

You work as a lab assistant. Each morning you are responsible for grouping the correct number of test tubes for each experiment that will be conducted that day. Today 40 test tubes will be used for 12 experiments. The first two experiments will require 4 test tubes each. Six of the experiments will require 3 test tubes each, and 2 of the experiments will require 2 test tubes each. Each of the two remaining experiments will use exactly the same number of test tubes.
Which calculation is appropriate to perform first when determining the number of test tubes that will be used for each of the two remaining experiments?
A) 10/2
B) 40 − 30
C) 40 − 12
D) 2(4) + 6(3) + 2(2)
Answer: D
Step-by-step explanation:
In total 40 test tubes are required for 12 experiments.
The first two experiments will require 4 test tubes for each.
Hence, there will be a requirement of = 8 test tubes.
Six experiments require 3 test tubes each.
Hence, these 6 experiments will take 18 test tubes.
Other 2 experiments will take 2 test tubes.
Here, = 4 test tubes will be required.
Till now a total of (8 + 18 + 4) = 30 test tubes have been used.
The remaining number of test tubes is (40 - 30) = 10.
The remaining experiments require test tubes.
The first calculation to perform is 2(4) + 6(3) - 2(2).

What is the natural phenomenon that will be explained? or What do we see in nature because of this story? What did the character learn that relates to the nature?
(Ares god of war)
Answer:
“These phenomena, like all others, demand an ultimate exposition of the truth.” This innocuous passage from a 22 March 1930 review in Nature of the book Growth and Trophic Movements of Plants by Jagadis Chandra Bose caught Gregory’s eye: it shared his vision of science as the search for a deep connection with the absolute truth. The review’s 26-year-old author, Lionel John Farnham Brimble (pictured) — Jack to his friends — was duly asked to join the Nature team as an assistant editor in 1931. Like Gregory, Brimble had earlier passed over a career in research to be an educator and communicator of science, and he flourished in the Nature office. In the late 1930s, he actively pushed for schools to teach biology, particularly his speciality of botany, which was previously taught only to girls in Britain.

Cell Phone Plan A charges $25 per month plus $10 per gigabyte of data. Cell Phone Plan B charges $50 per month plus $5 per gigabyte of data. What number of gigabytes of data results in the same cost for one month?
Answer:
[tex]gb = 5.[/tex]
Step-by-step explanation:
[tex]plan \: A. : \\ 25(per \: month) \: + 10(per \: gb) \\plan \: B. : \\ 50(per \: month) \: + 5(per \: gb) \\for \: both \: plan \: to \: be \: equal \: based \: on \: gb : \\ 50 + 5gb = 25 + 10gb \\ 5gb = 25 \\ gb = 5.[/tex]
The number of the Gega bytes for the same cost will be 5 GB.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Cell Phone Plan A charges $25 per month plus $10 per gigabyte of data. Cell Phone Plan B charges $50 per month plus $5 per gigabyte of data.
The two equations can be written as,
Plan A, 10G + 25
Plan B, 5G + 50
Equate two equations for the same cost.
10G + 25 = 5G +50
10G - 5G = 50 - 25
5G = 25
G = 5 gb
Therefore, the number of the Gega bytes for the same cost will be 5 GB.

Phillp and Arnold are helping their teacher buy supplies for a research project.
The teacher gave Phillip $39.00 to buy pencils from the school store. The pencils come in boxes of 12 and cost $1.95 per box.
Arnold was given $48.00 to buy index cards at an office supply store. Index cards are sold in packs of 200 cards and cost $4.80 per pack.
Each student will receive a bag containing three pencils and 25 index cards. How much will each bag cost?
Part A. Create an equation to model how many boxes of pencils Phillip can purchase. Solve the equation. (5 points)
Part B: How many pencils was Phillip able to purchase? (5 points)
Part C: Create an equation to model how many packs of note cards Arnold can purchase. Solve the equation. (5 points)
Part D: How many note cards was Arnold able to purchase? (5 points)
Part E. In a complete sentence, answer how many bags of 3 pencils and 25 note cards can Arnold and Phillip create (5 points).
Answer: Part A
20 boxes of pencils
Part B
240 pencils
Part C
10 boxes of note cards
Part D
2,000
Part E
80 bags
Step-by-step explanation:
Part A
Divide 39.00 by 1.95 and you should get your answer
Part B
take the answer you got from part a and multiply it by the number of pencils that are in the box
Part C
take 48.00 and divide it by 4.80 and you should get your answer
Part D
take your answer from Part C and multiply it by how many card are in a box and you should get your answer
Part E
divide the amount of pencils by three and it gives you 80 and for the cards do the same but take the amount of cards and divide it by 25 and it gives you 80 so the amount is 80 bags.
