K(2, 7), L(6, 12), M(13, 13), N(9.8) (Slope Formula) is it a parallelogram?

1 answer:

8 0

angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.

What in mathematics is a parallelogram?

A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal).
A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus.

Slope Formula: y2-y1/x2-x1

KL: 12-7/6-2 = 5/4

LM; 13-12/13-6 = 1/7

MN: 8-13/9-13 = 5/4

KN: 7-8/9-2 = 1/7

Since angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.

You are looking at a 260 foot by 180 foot building lot to subdivide and build two houses. Your town requires 1/2 acre (one acre

Varvara68 [4.7K]

Answer:

You have 1.07 acres in this building lot and you can only build 2 houses.

Step-by-step explanation:

You are looking at a 260 foot by 180 foot building lot to subdivide and build two houses.

We are given that 1 acre = 43,560 square feet.

In this building plot (260 foot by 180 foot), the area is:

260 * 180 = 46,800 square feet

Hence, the number of acres we have in this lot is:

$\frac{46800}{43560} = 1.07$

Since your town requires 1/2 acre to build a house, the number of houses that you can build on it will be:

$\frac{1.07}{\frac{1}{2} } = 1.07 * 2 = 2.14$

Since the number of houses can only be whole number, we approximate to nearest whole number ≅ 2 houses.

You have 1.07 acres in this building lot and you can only build 2 houses.

X - y = 0<br><br>A, B, C, or D

skad [1K]

Answer: D

Step-by-step explanation:

Using the equation y = mx + b.

m represents the slope

b represents where the line crosses the y axis.

We can attempt to set up the equation given in the same way.

x - y = 0

Add y to both sides and the 0 can drop out.

x = y

This is also equal to:

y = x

In this equation the m is equal to 1 and the b is equal to 0.

Taking this into account the answer is D.

Find C. round to the nearest tenth:

Anna [14]

Answer:

56.3 cm

Step-by-step explanation:

$\dfrac{\sin 28^\circ}{27} = \dfrac{\sin 102^\circ}{c}$

$c\sin 28^\circ = 27 \sin 102^\circ$

$c = \dfrac{27 \sin 102^\circ}{\sin 28^\circ}$

$c = 56.3$

Answer: 56.3 cm
