Pauline chasse has just signed a lease agreement with landlord, wayne godbrey to rent a house he owns in delano. The lease states definite beginning (january 1, 2016) and ending (october 30, 2016) dates, and sets forth the rent amount and due dates and all additional property and personal information required in such a lease. Wayne hands a copy to pauline, but she notices that he has not signed it. When she comments about this to him, he tells her that signatures are not necessary since the lease is for less than a year. Which of the following is true of this situation?.

Answers

The correct option that is true as regards Wayne's situation about the lease is;

B; Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

The missing options are;

Under the Statute of Frauds in California,

A) leases of less than one year are not even required to be in writing, and therefore, signatures are not required.

B) Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

C) Leases of less than one year are not required to be in writing; but if there is a written lease, then it must be signed by both the lessee and lessor.

D) Because the property being leased is located in Northern California, a lease agreement is required to be both written and signed by the lessor if the lease period is for 6 months or more

Now, California has some principles that guide the regulation of the real estate industry and according to the California Principles of Real State, it has to be said that leases of less than one year are not required to be in writing.

Now, even though the law stated that the consent of both parties are not enough to bind themselves in the lease agreement, it is recommended that just for the sake of keeping things legally binding as regards the agreement between both parties, then both parties may state it in written and the lessor must sign it.

What is the mass in kilograms of 14. 0 l of gasoline.

Answers

Answer:

The density of gasoline is 0.755 kg/L

ῥ_{gasoline} = 0.755 kg/L

And density is mass per volume.

ῥ = mass / volume

0.755 kg/L = mass / 14

mass = 0.755 x 14

mass = 10.57 kg

The mass in kilograms of 14.0 L of gasoline is about 10.57 kg. Note that this is just the rough value. As density of gasoline varies from 0.71 to 0.77 kg/L. SO the mass of 14.0 L of gasoline can be anywhere between 9.94 kg and 10.78 kg.

A cube of aluminum measures 3 cm on each side and weighs 81 g. What is its density? (hint: find the volume of the block first).

Answers

Answer:

3 grams per cubic centimeter.

Explanation:

density = mass ÷ volume.

d = m ÷ v.

m=81 g.

volume = length × width × height.

volume = 3 cm × 3 cm × 3 cm = 27 cubic centimeters.

v = 27 cubic centimeters.

d = 81 ÷ 27

density = 3 grams per cubic centimeter.

If the coordinates of one vertex of a triangle is (-4,-1), what will be the its new coordinates if the triangle slides 6 units to the right?.

Answers

Transformation involves changing the position of a point in the coordinate plane

The new coordinate is (-10,-1)

The vertex (A) of the triangle is given as:

[tex]A = (-4,-1)[/tex]

The rule of sliding the triangle 6 units right is:

[tex](x,y) \to (x - 6,y)[/tex]

So, we have:

[tex]A' = (-4 - 6,-1)[/tex]

Subtract 6 from -4

[tex]A' = (-10,-1)[/tex]
