Based on the data, the median time it takes players to complete the game is 1148 minutes.

<h3>What is the median?</h3>

It is the mathematical value that is the middle when values are sorted.

<h3>How to find the median time?</h3>
  • Organize the values

457 - 548- 866 - 952 - 976 - 1037 - 1148 - 1235 - 1245- 1431-1486 - 1759 - 1864

Identify the value of the middle

Considering there are 13 values, the value of the middle is the value number 7 or 1148.

Note: This question is incomplete because the data is missing, below I attached the missing section,

A woman bought some large frames for $19 each and some small frames for $9 each at a closeout sale. If she bought 18 frames for
MAXImum [283]

Answer: 6 large frames and 12 small frames

Step-by-step explanation:

We define the following:

x = number of large frames

y =  number of small frames

Make the following equations:

x + y = 18

19x + 9y = 222

Use system of equations to solve. We find the value of x first.

y = 18 - x

⇒ 19x + 9(18 - x) = 222

⇒ 19x + 162 - 9x = 222

⇒ 10x + 162 = 222

⇒ 10x = 60

⇒ x = 6

Find value of y:

6 + y = 18

y = 12

∴ 6 large frames and 12 small frames were purchased.

68.64 divided by 2.4 SHOW WORK PLEASE
34kurt

Answer:28.6

I started by seeing how many 2.4 can go into 68.64. I found that it is pretty easy to find that if you multiply the 2.4 by ten you get 24 so we do that twice and have 48. We then subtract 48 from the 68.64 which leaves us with 20.64. If we multiply 2.4 by 5 we get 12 so once again subtract 12 from that 20.64 and now we are left with 8.64. So now we need to figure out how many more 2.4 are left well it is more than three because three gives us 7.2 so let’s subtract that from it now we are left with 1.44. Now we need to find out what times 2.4 gives us 1.44. Well it would be .6. So now if we add up everything we get the answer of 28.6. Sorry if this very complicated

A ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the len
masha68 [24]

Answer:

25\text{ feet}

Step-by-step explanation:

The ladder, ground, and building form a right triangle where the vertical distance between the top of the ladder and the bottom of the ground is one leg, the horizontal distance between the bottom of the ladder and the building is another leg, and the length of the ladder is the hypotenuse.

For any right triangle, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared (a^2+b^2=c^2), where c is the hypotenuse.

Let the length of the ladder be \ell (hypotenuse of right triangle). The distance between the top of the ladder and the ground (vertical distance) can be represented as \ell -1.

From the Pythagorean Theorem, we then have:

7^2+(\ell-1)^2=\ell^2

Expand using (a-b)^2=a^2-2ab+b^2:

49+\ell^2-2\ell+1=\ell^2

Subtract \ell from both sides and add 2\ell to both sides:

49+1=2\ell

Combine like terms:

50=2\ell, \\2\ell =50

Divide both sides by 2:

\ell=\frac{50}{2}=\boxed{25\text{ feet}}

Therefore, the length of the ladder is 25 feet.
