Eduardo flips a coin three times and gets tails only once, so his fraction of tails so far is 1/3 . Eduardo says, “Next time I flip my coin, I am much more likely to get tails because that would make my new fraction of tails 2/4 which is equal to the probability of getting tails.”

FALSE ANSWERS/SCAMS/TROLLS WILL IMMIDIATELY BE REPORTED!

Answers

Answer:

256 sq cm

Step-by-step explanation:

cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.

The cross-section described is shown below.

The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.

         A=lw

             =(16cm) (16cm)

                =256 sq cm  

So, the area of the cross-section is 256 sq cm.

The answer to that would be 3/8

Answer:

I got 11/12

Step-by-step explanation:

Because you would take 2/3 × 1/4

They don't have the same denominators so you have to find a multiple. 12 is a multiple of both 3 and 4. In order to get a denominator of 12 for 2/3 you would have to multiply 3 by 4 and 2 by 4 leaving you with 8/12. Then you would have to multiply 1 by 3 and 4 by 3 leaving you with 3/12. Then you add them giving you 11/12. Hope this helps

Step-by-step explanation:

Answer:

m∠A=60,m∠ B=60, m∠C=60°

Step-by-step explanation:

We know that the interior angles of a triangle total up to 180°. We also know that the six angles given are congruent. So we can do 180÷6=30. So each angle equals 30. There are two of these angles at one angle of the whole triangle. So we can do 30×2=60 for each angle of the triangle. Hope this helps :)

Answers

Answer:

A.  26.10 cm

B. 118.95 cm

Step-by-step explanation:

ST = 41^2 - 40^2 =  c^2  = hypotenuse

ST = 1681 - 1600 = c^2

ST = c^2 = sq rt 681 =26.0959767014 = 26.1cm

Nearest 100th = 26.10

Length = 26.10 cm to nearest 100th

Perimeter of RSU we find (M) of SU first then add that to the other 3 lengths on the exterior of the triangle.

SU = 10^2 + 26.1^2 = c^2 = hypotenuse

SU = 100 + 681.21 = c^2

SU = c^2 = sqrt 781.21 = 27.9501341678 = 27.95cm

P TOTAL RSU  = SU + TR + RS + TU

= 27.95 + 40+ 41 + 10 = 118.95cm
