Do all circles have all right angles? <br><br>Yes or no​
Zarrin [17]

Answer:

They do

Step-by-step explanation:

Both have 4 90 degree (right) angles.

A triangle has 3 sides and 3 angles. The angles of a triangle always add up to 180 degrees.The “angle” of a circle is 360 degrees – all the way around.

Hope this helps (Sometimes i think circles don't have any angles at all)

Stells [14]

Answer: Expression used to find the total ribbon she used = x+11.2

And

The length of brown ribbon is used to make a bow for a dress = 11.2 inches

Expression need to find the total ribbon she used will be sum of blue and brown ribbon altogether

i.e. x+11.2 inches

So, the required expression will be x+11.2 inches

Ms. Tucker travels through two intersections with traffic lights as she drives to the market. The traffic lights operate indepen
sleet_krkn [62]

Answer:

b. 0.45.

Step-by-step explanation:

The total possible outcome of a probability is 1

Given;

Probability that both lights will be red when she reaches them = 0.22

Probability that the first light will be red and the second light will not be red = 0.33

Probability that the second light will be red when she reaches it = x

These are all the possible outcomes, therefore

0.22 + 0.33 + x = 1

0.55 + x = 1

x = 1 - 0.55

x = 0.45

Option b

I dont understand this problem
Fiesta28 [93]

Answer:

D and F

Step-by-step explanation:

x^{2}+4x+4=12 can be rewritten as x^{2} +4x-8=0.

From there you can use the quadratic formula x=\frac{-b±\sqrt{b^{2}+4ac } }{2a} (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.

x=\frac{-4±\sqrt{4^{2}-4(1)(-8)} }{2(1)}

Then you get x=\frac{-4±\sqrt{16+32}}{2}

Then you get x=\frac{-4±\sqrt{48} }{2}

So x=-2±\frac{4\sqrt{3} }{2}

Which means x=-2+2\sqrt{3} or -2-2\sqrt{3} which are choices D and F.
