Which of the following is a characteristic of car sharing
devlian [24]
Although every CSO is different, carsharing has a number of distinct characteristics that are the same within every CSO:

Carsharing is defined by its environmental and social purpose, rather than business and financial objectives.Carsharing is designed for local users in support of community transit and environmental goals. Its mission, vision and values lead to actions aimed at decreasing personal car ownership, reducing vehicle distance travelled, improving urban land use and development, providing affordable access to vehicles for all constituencies, as well as motivating residents to walk, cycle and take buses and trains, and decreasing dependence on fossil fuels while reducing the emission of greenhouse gases.Carsharing is a membership based service available to all qualified drivers in a community. No separate written agreement is required each time a member reserves and uses a vehicle. All CSOs offer members access to a dispersed network of shared vehicles 24-hours, 7 days a week at unattended self-service locations.

Carsharing is primarily designed for shorter time and shorter distance trips as an extension of the transportation network, providing a public service designed to enhance mobility options. Longer trips may be available to further discourage car ownership. CSOs help members save money over the cost of individual car ownership by encouraging members to drive less often, plan trips more, use other modes of transportation more, and share fuel efficient vehicles when a car is needed.

Alex_Xolod [135]

Answer:

0.02

Step-by-step explanation:

The volume of the earth's oceans is approximately 1.34\cdot 10^{9}1.34⋅10

1, point, 34, dot, 10, start superscript, 9, end superscript cubic kilometers (\text{km}^3)(km

)left parenthesis, start text, k, m, end text, cubed, right parenthesis, and ocean water has a mass of about 1.03 \cdot 10^{12}\,\dfrac{\text{kg}}{\text{km}^3}1.03⋅10

​

1, point, 03, dot, 10, start superscript, 12, end superscript, start fraction, start text, k, g, end text, divided by, start text, k, m, end text, cubed, end fraction .

To simplify, we will use the product of powers property of exponents that says that x^a\cdot x^b = x^{a+b}x

a

b

=x

a+b

x, start superscript, a, end superscript, dot, x, start superscript, b, end superscript, equals, x, start superscript, a, plus, b, end superscript.

\qquad 1.34\cdot 10^{9}\,\cancel{\text{km}^3} \cdot 1.03 \cdot 10^{12}\,\dfrac{\text{kg}}{\cancel{\text{km}^3}} = 1.3802 \cdot 10^{21}\,\text{kg}1.34⋅10

Hint #2

Next we want to know what portion of the earth's mass this represents. We have:

\qquad \begin{aligned} \dfrac{\text{mass of the oceans}}{\text{total mass of the earth}} &= \dfrac{1.3802 \cdot 10^{21}\,\text{kg}}{6\cdot 10^{24}\,\text{kg}} \\\\ &= \dfrac{1.3802}{6\cdot 10^{3}} \\\\ &= \dfrac{1.3802}{6000} \\\\ &= 0.0002300\overline{3} \end{aligned}

total mass of the earth

mass of the oceans

1.3802⋅10

​

=

1.3802

​

=

6000

1.3802

​

=0.0002300

3

​

To convert this to a percent, we multiply by 100100100, so the oceans represent 0.02300\overline{3}\%0.02300

3

%0, point, 02300, start overline, 3, end overline, percent of the earth's total mass, according to these figures.

Hint #3

To the nearest hundredth of a percent, 0.020.020, point, 02 percent of the earth's mass is from oceans.

Make y the subject: <br><br> 5x + 2y = 11
Anton [14]
Does that mean solve for y? If so, here it is:
5x + 2y = 11.

Move the x term by subtracting.
2y = -5x + 11

Divide by 2.
y = -5/2x + 11/2
