Natasha2012 [34]3 years ago
6 0

The answer is 4.55

When you divide 5 by 11 you will get  0.45454545454 than when you multiply these numbers by 10 you will get 4.54545454545 and then the rounded answer is 4.55.

Find x. You have to use Pythagorean theorem
Anuta_ua [19.1K]

Answer:

x = √18 = 4.24

Step-by-step explanation:

The radius is half of diameter so radius is 6/2 = 3

Right triangle is formed by 2 equal sides which is the same as radius

According to Pythagorean theorem: x^2 = 3^2 + 3^2

x^2 = 9 + 9 = 18

x = √18 = 4.24

Can somebody help me with this?
Elis [28]
The answer is choice D because we are adding the two angles UVW and WVX to form the larger angle UVX. The angle addition postulate basically says "glue two adjacent angles together and you can form a larger angle" more or less. It is similar to the segment addition postulate.

Part A
Volgvan

Answer:

Part A = C

Part B = 1/12

Step-by-step explanation:

Part A= this is because you need all the outcomes from the coin and from the dice joined together .

Part B= Because there is only one outcome that shows how you get a head on the coin and 6 on the dice.

Need help with pre-cal
timurjin [86]

A plot of the points A(-2, 11), B(5, 7), C(1, 0) is given by the option;

  • D

  • The triangle is a right triangle given that (AC)² = (AB)² + (BC)²

  • The area of the ∆ABC is 32.5 square units.

  • Sum of the squares of the lengths of the legs of the triangle = <u>130</u>

  • Square of the length of the hypotenuse of the triangle = <u>130</u>

<h3>How can ∆ABC be proven to be a right triangle from its dimensions?</h3>

The coordinates of the vertices of the triangle are;

A = (-2, 11), B = (5, 7), C = (1, 0)

Therefore, on the coordinate plane, we have;

The highest and leftmost point of the triangle is the vertex, <em>A</em>

The second highest and rightmost point of the triangle is the vertex, <em>B</em>

The<em> </em>vertex of the triangle that is midway between <em>A </em>and <em>B </em>and the lowest vertex of the triangle is the vertex <em>C</em>

  • The<em> </em>correct<em> </em>option that shows the points ABC and triangle ABC is the option <em>D</em>.

The lengths of the sides of the triangle are;

AB = √((-2 - 5)² + (11 - 7)²) = √(65)

BC = √((5 - 1)² + (7 - 0)²) = √(65)

AC = √((-2 - 1)² + (11 - 0)²) = √(130)

Therefore;

(AC)² = 130 = (AB)² + (BC)² = 65 + 65

Which gives;

  • (AC)² = (AB)² + (BC)²

Therefore;

  • ∆ABC is a right triangle, from the definition of a right triangle.

The legs of ∆ABC are AB and BC

AC is the hypotenuse of ∆ABC

The area of ∆ABC is therefore;

Area = (1/2) × AB × BC

Which gives;

Area of ∆ABC = (1/2) × √(65) × √(65)

√(65) × √(65) = 65

  • Area of ∆ABC = (1/2) × 65 = 32.5

(AB)² + (BC)² = 65 + 65 = 130

Therefore;

  • Sum of the squares of the lengths of the legs of the triangle = 130

(AC)² = 130

  • Square of the length of the hypotenuse of the triangle = 130

Answer:

Step-by-step explanation:

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century.
