The total spent amount on water is $220
The total area is 37.5=75/2
The number of lots is 75/2/3/4=50 nos
Total rent is 50×50=2500
So 3/5 will go to david 2500×3/5=1500
2/5 will go to john 2500×2/5=1000
So 60% Renters choose 100 gallons
Total renters is 50
60% renters is 50×60%=30 nos
40% renters choose 70 gallons
40% of 50 is 20 nos
The tank fills twice
100×30+70×20=4400 to be filled
Per gallon cost is $0.05
So the total cost is 4400×0.5=$220
So they spent $220 on water

If the sum of a number and two is tripled, the result is five less than twice the number . Find the number
If the sum of a number and two is tripled, the result is five less than twice the number, the number is - 11
Let the given number be x,
the number, x is added with 2 and then it is tripled which means (x + 2)*3 is equal to five less than two times of that number which is 2x - 5
3(x + 2) = 2x - 5
3x + 6 = 2x - 5
3x - 2x = - 5 + (-6)
x = - 11
Therefore, If the sum of a number and two is tripled, the result is five less than twice the number, the number is - 11

Step-by-step explanation:
Newton’s law of cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small.
Definition: According to Newton’s law of cooling, the rate of loss of heat from a body is directly proportional to the difference in the temperature of the body and its surroundings.
Answer:
Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei to atomic nuclei to form more energetically stable atomic nuclei. Radioactive decay is a highly exoergic, statistically random, first-order process that occurs with a small amount of mass being converted to energy. Since it is a first-order process, each radioactive species is characterized by its own half-life, the length of time in which an initially very large number of such nuclei will have decayed to only half the original number.

one cubic foot holds 7.48 gallons of water and one gallon of water 8.33 pounds. How much does 5.1 cubic ft of water weigh in pounds? In tons?
The 5.1 cubic ft of water weighs 317.77 pounds
The weight of 5.1 cubic ft of water in tons is 0.16 tons
Calculating weightFrom the question, we are to calculate how much 5.1 cubic ft of water weigh in pounds
From the given information,
"one cubic foot holds 7.48 gallons of water"
Therefore,
5.1 cubic ft of water = 5.1 × 7.48 gallons of water
= 38.148 gallons of water
Also,
"one gallon of water 8.33 pounds"
That is,
38.148 gallons of water = 38.148 × 8.33 pounds
= 317.77 pounds
Thus, 5.1 cubic ft of water weigh 317.77 pounds
For the weight in tons
NOTE: 1 pounds = 0.0005 tons
∴ 317.77 pounds = 0.0005 × 317.77 tons
= 0.158886 tons
≈ 0.16 tons
Hence, the weight of 5.1 cubic ft of water in tons is 0.16 tons

a 42 inch string is to be cut so that one piece is 7 inches longer than the other. what is the length of the shorter piece?
Answer:
17.5 inches
Step-by-step explanation:
Let the length of the shorter piece be x
Shorter piece + Longer piece = Whole string
x + (x + 7) = 42
x + x + 7 = 42
Both sides minus 7 to remove the 7 from the left side of the equation.
2x + 7 - 7 = 42 - 7
2x = 35
x = 17.5 inches

If the reading on a mercury manometer at 25 C is 56.38 cm the local acceleration of gravity is 9.832m.s^-2 atmospheric pressure is 101.78kpa The absolute pressure in kpa being measured is: 176.803kPa.
Absolute pressureUsing this formula
Pabs=Pg+Patm
Where:
Pabs= Absolute pressure.
Patm=Atmospheric pressure
ρm=Density of mercury
g=Acceleration of gravity
h=Reading on a mercury manometer
Let plug in the formula
Pabs=101.78×10³Pa+( 13.534×10³kg/m×9.832 m/s²×0.5638 m.
Pabs=101.78×10³Pa+75.023×10³kg/m.s²

A recent study of 50 U.S. chess players details such things as the number of years the players have been active and the chess ratings of the 50 players. (A chess rating is a number, with a higher number indicating greater expertise.) The chess rating data for the sample of 50 players are summarized in the following histogram.
Using the given histogram, we have that 90% of the players in the sample have scores that are less than 2300.
What is the missing information?This problem is incomplete, but researching it on a search engine, we have that the histogram states as follows:
6 of these players have scores between 300 and 700.6 of these players have scores between 700 and 1100.13 of these players have scores between 1100 and 1500.14 of these players have scores between 1500 and 1900.6 of these players have scores between 1900 and 1300.5 of these players have scores between 2300 and 2700.It asks the proportion of players in the sample with scores that are less than 2300.
What is an histogram?An histogram is a graph that shows the number of times each element of x was observed.
Above, we already gave the amounts presented by histogram, and we have that 45 out of 50 players have scores that are less than 2300, hence the proportion is given by:

(−4, 0)
The turning point is the point where the function changes its slope for the given mode function f(x)=|x|+4 the turning point is at (0,4) so option (B) will be correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand behavior of the graph.
Given the mode function,
f(x)=|x|+4
For x < 0 the function f(x) will be
f(x) = -x + 4
For x > 0 the function f(x) will be
f(x) = x + 4
Now,
Slope at x < 0 → f'(x) = -1
Slope at x > 0 → f'(x) = +1
Since the slope is changing at x = 0 there fore x = 0 will be the turning point of the graph.
Hence "The turning point of the given mode function f(x)=|x|+4 will be at x = 0".
