Answer:

arc PSQ is the name

I believe it would just be called a semi circle.

Major arcs are > 180°

Minor arcs < 180°

Exactly 180°, I'm not sure

The perimeter of the square is equal to the perimeter of the triangle. What are the side lengths of each figure? square: ? units
blsea [12.9K]

Answer:

<em>Square= 12 units</em>

<em>Triangle long sides= 19 units</em>

<em>Triamgle short side= 10 units</em>

Step-by-step explanation:

<em>It is a square, so all sides are the same.  That means 3x+3 equals 4x.  What number can be subsituted into x to equal 4?  If x is 3, then 3x+3 would be 3(3)+3.  It equals 12.  4 times 3 is also 12.  It works!  That also means the square's side is 12 units.</em>

<em>Square= 12 units</em>

<em />

<u><em>So, x=3</em></u>

<em />

<em>The triangle's longer sides are 7x-2.  Subsitute x in, which is 3, and you get 7(3)-2.  It equals 19.  The two longer sides of the triangle are the same length, so both are 19 units.</em>

<em>Triangle long sides= 19 units</em>

<em />

<em>The triangles shorter side is 2x+4.  Subsitute 3 in for x and you get 2(3)+4.  It equals 10, so the shorter side is 10 units.</em>

<em>Triangle short side= 10 units</em>

Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression cou
Lady bird [3.3K]

3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Step-by-step explanation:

<u>DATA:</u>

Length of strips Eli need is 2.5 feet long

Length of roll of ribbon is 7.5 feet long

Number of strips that can be cut from the 7.5 feet long roll is x

<u>SOLUTION:</u>

To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.

Number of strips that can be cut = \frac{Total Length of roll}{Length of strips needed}

x = \frac{7.5}{2.5}  (expression)

x = 3 strips

Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Hey there :)

We know the distance formula is:
D = \sqrt{(x2-x1)^2+(y2-y1)^2}

1) Coordinates are: ( -10, -5 ) , ( 8 , 5 )
                                    ↓   ↓       ↓    ↓
                                    x₁ y₁     x₂   y₂
We plug in the values 
D =\sqrt{(8 -(-10))^2+(5-(-5))^2}
    ≈20.59 ≈ 20.6 (nearest tenth)

We do the same for the rest

2) Coordinates are ( 10 , 0 ) , ( -2 , 1 )
D = \sqrt{(-2-10)^2+(1-0)^2}
   ≈ 12.04 ≈ 12.0 (nearest tenth)

3) Coordinates are ( 4 , 8 ) , ( 7 , -8 )
D = \sqrt{((7-4)^2+(-8-8)^2}
   ≈ 16.27 ≈ 16.3 (nearest tenth)

4) Coordinates are ( -10, -4 ) , ( 8 , 8 )
D = \sqrt{(8-(-10))^2+(8-(-4))^2}
    ≈ 21.6 (nearest tenth)

5) Coordinates are ( 6 , -3 ) , ( -8 , 9 )
D = \sqrt{(-8-6)^2 + (9-(-3))^2}
   ≈ 18.4 (nearest tenth) 

You can find the matching below :)

How many degrees does each angle of an equilateral triangle measure? 45o, 60o, 90o, 100o
LiRa [457]
A triangle has 3 angles.

The sum of the measures of the angles of a triangle is 180.

In an equilateral triangle, all angles have the same measure.

180/3 = 60

Answer: 60 degrees.
