The builder buys 16.1 acres of land to develop a new set of walking trails and baseball fields. The builder plans to use .25 of the land for baseball. How many acres will be used for baseball?

Answers

Answer: 4.025 acres.

Step-by-step explanation:

Given: The builder buys 16.1 acres of land to develop a new set of walking trails and baseball fields.

Thus, the total land he has =16.2 acres

If the builder plans to use 0 .25 of the land for baseball.

Then the land will be used for baseball $0.25*16.1=4.025\ acres$

Hence, only 4.025 acres of the land will be used for baseball.

In math, "of" almost always means "times".

(0.25) x (16.1 acres) = 4.025 acres .

Which statement can be used to prove that the two triangles are congruent? A: the HL Theorem

B: the Angle-Side-Angle Postulate (ASA)

C: the Angle-Angle-Side Theorem (AAS)

D: the SAS Postulate

Answers

Answer:

HL Theorem

Step-by-step explanation:

Here, we see that both triangles have a right angle, making them right triangles. We know that the hypotenuse must be equivalent, as it is the same line. Furthermore, we see that one of the legs from each triangle are equivalent. Therefore, we can use HL Theorem to prove these triangles are equal.

Answer:

The SAS postulate

Step-by-step explanation:

Longer lengths of the two triangles are equal (S)

The triangles are reflected about the line where their equal hyputenuses meet (S)
The right angle of one triengle is equal to the right angle of the other triengle (A)

Thus the two triangles are congruent as evidenced by the SAS postulate.
