Answer:

Step-by-step explanation:

if two parallel lines are cut by a traversal, the alternate exterior angles are congruent. If two lines are cut by a traversal and the alternate exterior angles are congruent, the lines are parallel. Corresponding Angles: The name does not clearly describe the "location" of these angles

Answer:

No

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

We see that: 4.1 + 1.3 < 8.4

=> Can't form a triangle from 4.1 cm, 8.1 cm and 1.3 cm

Slope of (0,45) (6,33) (15,15)

Vladimir [108]

Answer:

The slope is -2

Step-by-step explanation:

Given

$(x_1,y_1) = (0,45)$

$(x_2,y_2) = (6,33)$

$(x_2,y_3) = (15,15)$

Required

The slope (m)

Slope is calculated as:

$m = \frac{y_2 -y_1}{x_2 - x_1}$

So, we have:

$m = \frac{33 -45}{6 - 0}$

$m = \frac{-12}{6}$

$m =-2$

A fountain in the park has two circular pools that are the same size. What is the total area of the pools if the radius is 3 yar

mihalych1998 [28]

Answer:

56.6 square yards.

Step-by-step explanation:

Given:

A fountain in the park has two circular pools that are the same size.

<u>Question asked:</u>

What is the total area of the pools if the radius is 3 yards ?

<u>Solution:</u>

First of all we will calculate the area of a circular pool.

As we know:

$Area\ of\ circle=\pi r^{2}$

$=\frac{22}{7} \times(3)^{2} \\ \\ =\frac{22}{7}\times9\\ \\ =\frac{198}{7} \\ \\ =28.28\ square\ yards$

Area of circular pool nearest tenth = 28.3 square yards

Now, as given that both pools are of same size.

Total area of the pools = 28.3 square yards + 28.3 square yards

= 56.6 square yards.

Thus, the total area of the pools are 56.6 square yards.
