20x + 9 = 14x + 15 
<span>6x = 6 </span>
<span>x = 1 </span>

<span> So base angles are 20 + 9 means 29 degrees. To calculate the m of  angle k, subtract 29 from 180: </span>

<span>180 - 29 = 151 degrees.
hope it helps</span>

Which counterexample shows that the conjecture "All animals that can fly are birds" is false?
QveST [7]
It seems like you forgot to post the answer choices. However, bats are one animal where they can fly but they aren't birds. So this is one counter-example to prove the claim false. Another example would be any flying insects.

Answer:

<h2>The circumference is multipled by 4.</h2>

Step-by-step explanation:

The formula of an area of a circle"

A=\pi r^2

The formula of a circumference of a circle:

C=2\pi r

The area multipled by 16:

16A=16\pi r^2\\\\16A=\pi(4^2r^2)\\\\16A=\pi(4r)^2

The radius has increased fourfold, therefore:

C'=2\pi(4r)=4(2\pi r)=4C

The circumference is multipled by 4.

You can calculate the area and check the circumference:

r=11.6\ in\\\\A=\pi(11.6)^2=132.56\pi\\\\16A=(16)(134.56\pi)=2152.96\pi\ in^2

Calculate the radius:

\pi r^2=2152.96\pi             <em>divide both sides by π</em>

r^2=2152.96\to r=\sqrt{2152.96}\\\\r=46.4\ in

Calculate the circumference of both circles:

r=11.6\ in\\\\C=2\pi(11.6)=23.2\pi\ in

r=46.4\ in\\\\C'=2\pi(46.4)=92.8\pi\ in

\dfrac{C'}{C}=\dfrac{92.8\pi}{23.2\pi}=4\to C'=4C

Find the perimeter of a square that is 3 3/4 inches on a side. 7 inches 15 inches 12 inches 30 inches
RoseWind [281]

Answer:

  15 inches

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of its sides. A square has 4 sides, all the same length. We can either add up the side lengths, or we can recognize that multiplication of one side's length by 4 is a useful alternative.

  perimeter = 4 × (3 3/4 in)

  = (4×3 +4×3/4) in

  = 12 in + 3 in = 15 in

PART 20 ! PLEASE HELP ALGABRA 1
34kurt

Answer:

B

Step-by-step explanation:

If it cost $2.05 for each hamburger that's going to be your constant.

And it says plus an additional $2,000 so you will add that after 2.05x.

And it says 13,025 is the total so that would be on the left.

13,025 = 2.05x + 2,000

I'm 100% sure

I took Honors Algebra 1 in 8th grade, so you can trust me!!!

Grayson knits 17 squares on Thursday. He knits 5 more squares each day from Friday through Saturday. How many squares does Grays
jekas [21]
27 squares because both Friday and Saturday he knits 5 squares, if you add them together you will get 10 squares. Then you have to add the 10 squares to the original 17 squares he made.
