Answer:d
Explanation:
The participants at the meeting should consider the cost and benefits of each way before choosing any one of the several ways as suggested by the mayor about how the town could provide child care to families in which both parents work.
What is cost and benefit analysis?A systematic method for determining the advantages and disadvantages of options is cost-benefit analysis (CBA), sometimes known as benefit-cost analysis. It is used to choose solutions that will maximise savings while achieving benefits in areas including transactions, activities, and functional business requirements. A CBA can be used to assess current and possible courses of action, as well as to calculate or compare a decision's value to its cost. It is frequently used to assess commercial deals, project investments, and judgments about business or policy (especially public policy).
What is child care?The care and supervision of one or more children at a time, whose ages range from two weeks to eighteen years, is known as child care, also referred to as day care. A vast range of specialists, organisations, settings, activities, and social and cultural norms fall under the broad issue of child care.
Professional caregivers provide care either at centres (such as daycares, preschools, and schools) or at homes (nannies or family daycare). The majority of childcare facilities mandate that staff members undergo rigorous first aid training and hold CPR certification.

Global changes and problems such as population growth, deforestation, chemical spills, air pollution, burning natural gas, coal and oil, pesticides, industrial gases, carbon dioxide, emissions contribute to global warming which results in
Answer:
If the choices are as follows...
A.Extreme Weather Events
B.Shortage of potable water around the World
C.More frequent heat waves and droughts
D.All of the above
Explanation:
Then It should be D.
Global changes and problems such as population growth, deforestation, air pollution, burning natural gas, coal and oil, pesticides, industrial gases, carbon dioxide, and emissions contribute to global warming which results in a disbalance in the natural ecosystem and an increase in temperature.
What is deforestation?Deforestation is referred to as the cutting down of trees in large numbers which reduced the quantity of plant vegetation in order to perform commercial activities with the objective to develop better infrastructure.
If the number of greenhouse gases in the atmosphere suddenly increased, more heat would be radiated toward the surface of Earth, causing a dramatic rise in temperature.
Global issues and adjustments like deforestation, air pollution, burning of fossil fuels like coal, oil, and gas, pesticides, industrial gases, and emissions all contribute to global warming, which disrupts the natural ecosystem and makes it harder for organisms to survive.

Explain all the types of erosion caused by water
Answer:
There are three types of soil erosion caused by water. They are: Sheet, Rill and Gully.
Sheet Erosion
This type of erosion takes away the top soil over a wide area thereby making it look as though it took a sheet of the top soil. As a result, this is not easy to notice at first glance because the soil from the whole area is gone so there is nothing to compare it to.
Rill Erosion
When water goes in channels and makes lines in the soil a by carrying off the soil that was previously on those lines, that is rill erosion. These channels must be shallow to be considered Rill erosion however because if they are too big, it would become gully erosion.
Gully Erosion
Gully erosion is much like Rill erosion but on a much larger scale. With gully erosion, the channels are much bigger and allow for more soil to be taken. Gully erosion can remove a lot of soil from an area. The Grand Canyon for instance was formed by Gully erosion.

Answer:
a) w = 98°
b) x = 137°
Explanation:
The reason is that they are angles at a point
Which means they are equal to 360°.
Example;
a) 165° + 97° + w = 360°
262° + w = 360°
You then group like terms
w = 360° - 262°
w = 98°

C. 1.4 degrees Fahrenheit
D. 2.1 degrees Fahrenheit
Answer:
Q1 china Q2 B. Electricity and heat production
Explanation:
The largest carbon dioxide emitter is China. The majority of greenhouse gas emissions are produced during the production of electricity and heat.
Of all the greenhouse gases, fluorinated gases have the greatest potential to cause global warming. The average global temperature rose 2.1 degrees Fahrenheit during the past century. Options (D), (B), (A), and (D) are thus correct in that order.
What is the greenhouse effect?The greenhouse effect is a phenomenon in which heat from a planet's host star passes through its atmosphere and warms the surface of the planet, but greenhouse gases in the atmosphere prevent part of the heat from going directly to space, making the world warmer.
Without greenhouse gases, Earth would be below freezing, but the planet's natural greenhouse effect prevents this from happening. Additionally, when greenhouse gas concentrations rise due to human activity, more heat is trapped and the Earth gradually gets warmer.
Hence, chronologically, Options (D), (B), (A), and (D) are correct.

On a cool summer morning in East Lansing, Michigan, the temperature was 7 ℃elsius and the air was saturated with RH = 100%. That afternoon, the temperature rose to 29° Celsius. If the same air mass remained in place all day (meaning the moisture content did not change throughout the day).
Required:
a. Would the relative humidity increase or decrease in the afternoon?
b. What was the relative humidity during that afternoon (rounded to the nearest percent)?
Answer:
The correct answer is -
a) The relative humidity decreases with an increase in temperature.
b) 25%
Explanation:
The dew point (Td) is the temperature at which the Relative humidity (RH) is 100%. So in the given question dew point, is (Td) is 7° C. The RH can be calculated by the formula:
[tex]RH: =100*\frac{(EXP((17.625*TD)/(243.04+TD))}{EXP((17.625*T)/(243.04+T)))}[/tex]
Putting the values of Td and T we get RH=
[tex]RH: =100*\frac{(EXP((17.625*7)/(243.04+7))}{EXP((17.625*29)/(243.04+29)))}[/tex]
= 25.02 or 25 %.
This globe from the atmospheric moisture investigation shows specific humidity, with blue and green being highest. What is a possible explanation for why specific humidity values are relatively low in the ocean adjacent to the western coast of southern Africa
Answer:
Due to temperature.
Explanation:
The values of specific humidity are relatively low in the ocean adjacent to the western coast of southern Africa because of the presence of temperature of large water bodies around the area. Humidity depends on the temperature of the air means if the temperature is higher than there is high humidity in the air because the air has the ability to hold more water vapors which ultimately increases humidity.
Qué nombre recibe la incapacidad de una población para reponerse después de un desastre
Answer:
Vulnerabilidad.
Explanation:
El término vulnerabilidad es una extensión de los enfoques convencionales de la pobreza. Se reconoció que la pobreza por sí sola no puede describir y explicar adecuadamente los problemas de desarrollo y las crisis sociales en las naciones, especialmente cuando estos no surgen de cuestiones puramente económicas, sino también climatológicas o de otra índole. La vulnerabilidad no solo significa deficiencia y necesidades insatisfechas, sino una condición social que se caracteriza por inseguridad e indefensión ante eventos externos. Las personas y poblaciones vulnerables están expuestas a choques y factores estresantes y tienen dificultades para afrontarlos. La vulnerabilidad debe entenderse como un proceso dinámico. Las personas afectadas pueden ser o volverse vulnerables de manera diferente según la situación. Las fases individuales de este proceso de vulnerabilidad van desde la vulnerabilidad básica (fase de afrontamiento o arreglo) a través de varios pasos intermedios hasta una catástrofe existencial, que se caracteriza por un colapso de la seguridad vital y la dependencia total de los afectados de las medidas de ayuda externa. Una hambruna es un ejemplo de tal colapso.
