Answer:

I found this over the internet and hope it helps:

A rectangle is a quadrilateral with all four angles right angles. It follows form this that the opposite sides are parallel and of the same length. A square is a quadrilateral with all four angles right angles and all four sides of the same length.

Also note that a square is always a rectangle, but a rectangle is not always a square.

Answer:

A square and rectangle are both quadrilaterals. They both have right angles.

A rectangle's opposite sides are parallel and equal , while all the square's sides are equal.

Every square is a rectangle, but not all rectangles are squares.

8. The talent show committee sold a total of 530 tickets in advance. Student
Alex Ar [27]

Answer:

Number of students tickets sold = x = 380 tickets

Number of adults tickets sold = y = 150 tickets

Step-by-step explanation:

Let

Number of students tickets sold = x

Number of adults tickets sold = y

x + y = 530 (1)

3x + 4y = 1740 (2)

From (1)

x = 530 - y

Substitute x = 530 - y into (2)

3x + 4y = 1740

3(530 - y) + 4y = 1740

1590 - 3y + 4y = 1740

- 3y + 4y = 1740 - 1590

y = 150

Substitute y = 150 into (1)

x + y = 530

x + 150 = 530

x = 530 - 150

x = 380

Number of students tickets sold = x = 380 tickets

Number of adults tickets sold = y = 150 tickets

Find the arc length if the Central Angle is 340 and the Circumference is 6.​
GenaCL600 [577]

Answer:

17/3

Step-by-step explanation:

      To find the length of the arc, we have to find what fraction of the circle is the arc. To find this, we do 340/360 because there are 360 degrees in a circle, and get 17/18. Since the circumference is 6, we take 17/18 of 6 which is 17/3.

6) The three points (15, 189), (9, 111) and (-7, y) are all on the
Leona [35]

Answer:

Step-by-step explanation:

If it's on the same line, that means that the slope from each point to the other must be the same.

Using the first given points, we can calculate the slope to be:

m = \frac{189-111}{15-9}=\frac{78}{6}=13\\

We can solve for y

13 = \frac{111-y}{9--7}\\13=\frac{111-y}{16}\\111 - y = 208\\y = -97\\

We can double check:

m = \frac{111--97}{9--7}\\m=\frac{208}{16}=13

How do I find the surface area of a right circular cone?
UkoKoshka [18]
Greetings!

"<span>How do I find the surface area of a right circular cone?"...
</span>
The formula to find the surface area of a right cone is :
=\pi r(r+ \sqrt h^2+r^2)

Lets it out:
r=5 and h=12

=\pi(5)((5)+ \sqrt (12)^2+(5)^2)
Follow PEDMAS.
=\pi(5)((5)+ \sqrt 169)
=\pi(5)((5)+ 13)
=\pi(5)(18)
=15.7079633(18)
=282.743339

The SA of the cone would be <span>282.743339.

Hope this helps.
