If donations are received from 45 people, each one should contribute 75 dollars to get the total necessary to build the playground.
How to calculate how much each donor should contribute?To calculate how much each donor must contribute, we must take into account the total money that it is worth to build the park. To do this, we perform the following operation:
25 × $135 = $3,375
So if 45 people donated, we need to divide this value by that number of people as shown below:
$3375 ÷ 45 = $75
Note: This question is incomplete because there are some information missing. Here is the missing information:
A neighborhood group wants to build a new playground using donations from residents. The amount needed from each donor varies inversely to the number of people donating. If 25 people donate, each of them would need to contribute $135. Solve for the amount each person needs to contribute if 45 people donate.

Answer:
$75.00
Explanation:
Given amount of people: 25.
Needed contribution: $135.
Total contribution: 25 * 135 = $3375
Divide $3375 by 45 to see how much each of the 45 people would need to contribute,
$3375/45 = $75.00
$75.00 is what each person would need to donate.
Suppose that a bored student wants to go to a restaurant for lunch, but she only has an hour in which to go, eat, and get back in time for class. Considering that it usually takes about 30 minutes in most restaurants to get served and to eat, what is the farthest restaurant the student can go to without being late for class? assume in this part that the student has a car that can accelerate to its top speed in a negligible amount of time. Also, the local speed limit is 30 mph and the student would not like to get a speeding ticket.
Well, it really depends, one would need to know the restraunts around them and know how long it would to take to get to them.
Now lets say there is one 10 minutes away from the school, but the serving time is a about 30 minutes, then again it would also depend on how fast the student can eat, assuming it takes about 20-30 minutes, the student would most likely be 10-20 minutes late.
Hope this helped!! (And good luck with getting the food!!) Have a nice day!!

The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹
The chemical reaction :
C₂H₅Cl ------> C₂H₄(g) + HCl(g)
Determine the value and unit of the rate constant ( K )let the rate of reaction be expressed as
R = k [ C₂H₅Cl ]ⁿ ---- ( 1 )
where : n = order
k = rate constant
From the table
2 = 2ⁿ
therefore n = 1
Hence we can rewrite equation ( 1 ) as
R = k [ C₂H₅Cl ] ¹ ( first order reaction ) ---- ( 2 )
Next step : substitute the value of C₂H₅Cl and initial rate into equation 2
0.630 * 10⁻³⁰ = k ( 0.1 ) ¹ M

Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks. Carbon sinks in the land and the ocean each currently take up about one-quarter of anthropogenic carbon emissions each year.

Consider the mass of the cart to be m1 and the angle the first cart sits on to be θ1, while the mass of the second cart as m2 and the angle it sits on to be θ2.

How can the expression for the acceleration be derived?A possible question is the expression for the acceleration, a in terms of the mass, m₁, m₂, and the angles θ₁ and θ₂.
The drawing representing the situation, obtained from a similar question and created with MS Visio, is attached
From the drawing, we have;
By equilibrium of forces, the tension in the cable, T, is given as follows;

Where;
a = The acceleration that the two carts experience
Equating both values of T gives;
m₁·a + m₁·g·sin(θ₁) = m₂·g·sin(θ₂) - m₂·a
m₁·a + m₂·a = m₁·g·sin(θ₁) - m₂·g·sin(θ₂)

What general trend does electronegativity follow on the periodic table.
Answer:
As you go across the table and the periods get higher, the electronegativity increases. As you go down the periodic table by groups, the electronegativity decreases
Explanation:
Answer:
electronegativity decreases down a group and increases from left to right of the table
Explanation:
electronegativity shows how well an atom can attract electrons to itself in a covalent bond.
It is measured on the pauling scale, and the most electronegative element is fluorine.
electronegativity decreases down the group, because the increasing number of shells decreases the attraction between the nucleus and outermost electrons.
Electronegativity increases from left to right of a row, as across the row the number of protons in the nucleus increases. This allows a stronger attraction between outermost electrons and the nucleus.
So electronegativity increases up a group and across the row of the periodic table. Fluorine is the most electronegative element, measuring 4 on the pauling scale ( 4 is the highest number).

Explanation:
A 7. 5 kg block is attached to a horizontally-mounted spring with a spring constant of 750 j/m2. The block is released from rest with the spring extended by 15 cm from its normal length of 27 cm. The horizontal surface along which the block moves is frictionless. How long (in s) will it take this system to complete 2. 5 oscillations?.
It takes the system 1.58 s to complete 2.5 oscillations
Period of oscillationThe period of oscillation of the horizontally mounted spring is T = 2π√(m/k) where
m = mass of block = 7.5 kg and k = spring constant = 750 N/m²Substituting the values of the variables into the equation, we have
T = 2π√(m/k)
T = 2π√(7.5 kg/750 N/m²)
T = 2π√(0.01 kgN/m²)
T = 2π × 0.1 s
T = 0.2π s
T = 0.2 × 3.142
T = 0.6284 s
T ≅ 0.63 s
Time to complete 2.5 oscillationsSince one oscillation = period = 0.63 s, then 2.5 oscillations = 2.5 × 1 oscillation = 2.5 × 0.63 s
= 1.575 s
≅ 1.58 s
So, it takes the system 1.58 s to complete 2.5 oscillations
