2 Answers:  A) line symmetry and B) rotational symmetry

=====================================================

Explanation:

We have line symmetry because we can draw a vertical line down the center, and this is a mirror line. One half folds over the vertical line to match up with the other half. There are other lines of symmetry as well.

We also have rotational symmetry because we can rotate the figure some amount of degrees and have it line up with its original image. The before and after will be identical. This applies to any regular polygon.

pishuonlain [190]

Answer:

He sold 180 chicken sandwiches and 150 burguers.

Step-by-step explanation:

Since 330 items were sold, then the amount of burguers and chicken sandwiches sold must be equal to this value. From this information we have:

burguers + sandwiches = 330

We know that each burguer cost $9 and each chicken sandwich cost $11.25 and that we made a total of $3,375. So we have:

9*burguers + 11.25*sandwiches = 3,375

From the first equation we have:

burguers = 330 - sandwiches

Applying it on the second equation:

9*(330 - sandwiches) + 11.25*sandwiches = 3,375

2,970 - 9*sandwiches + 11.25*sandwiches = 3,375

2.25*sandwiches = 3,375 - 2,970

2.25*sandwiches = 405

sandwiches = 405/2.25 = 180

So,

burguers = 330 - 180  = 150

He sold 180 chicken sandwiches and 150 burguers.

The formula for the slant height of a cone is , where S is surface area of the cone. Use the formula to find the slant height, l
liq [111]

we know that

The formula of the surface area of the cone is equal to

SA=\pi r^{2}+\pi rl

where

SA is the surface area

r is the radius of the cone

l is the slant height

in this problem we have

SA=500\pi\ ft^{2}\\r=15\ ft\\l=?

Solve the formula for l

SA=\pi r^{2}+\pi rl\\ \\\pi rl=SA-\pi r^{2} \\ \\l=\frac{SA-\pi r^{2} }{\pi r}

substitute the values

l=\frac{500\pi -\pi 15^{2} }{\pi15}\\ \\l=\frac{275}{15}\ ft\\ \\l=\frac{55}{3}\ ft\\ \\l=18\frac{1}{3}\ ft

therefore

<u>the answer is</u>

The slant height is 18\frac{1}{3}\ ft

Which inequality is equivalent to I x-4 I &lt;9
Leni [432]

(B) –9 < x – 4 < 9 inequality is equivalent to Ix-4I <9.

<h3>What is inequality?</h3>
  • Inequality is a statement of an order relationship between two numbers or algebraic expressions (greater than, greater than, or equal to, less than, or less than or equal to).
  • Inequality is defined as a difference in size, amount, quality, social position, or another factor.
  • Inequality occurs when you have ten of something and someone else has none.
  • (mathematics) A statement stating that one quantity is less than (greater than) another.

So, Ix-4I <9:

  • |x-4|<9 ⇒ -9 < x-4 < 9
  • -5 < x < 13

Therefore, (B) –9 < x – 4 < 9 inequality is equivalent.

The complete question is given below:

Which inequality is equivalent to I x-4 I <9?

A –9 > x – 4 < 9

B –9 < x – 4 < 9

C x – 4 < –9 or x – 4 < 9

D x – 4 > –9 or x – 4 < 9
